Analogues

Furosemide analogues according to the ATC code: Lasix, Furon, Furosemide injection solution, Fursemide.

Do not make the decision to change the drug yourself, consult your doctor.

pharmachologic effect

The active component of the drug has a diuretic property, helping to remove water from the body with magnesium and calcium ions.

The use of Furosemide in heart failure leads to a rapid decrease in the preload on the heart caused by the expansion of large veins.

The effect of the drug after intravenous administration occurs very quickly - after five to ten minutes, and after oral use - after an hour. The duration of the diuretic action of Furosemide varies from two to three hours. With reduced kidney function, the therapeutic effect of the drug lasts up to eight hours.

special instructions

  • Before starting treatment, you should make sure that the urinary system is functioning normally and that there is no violation of the outflow of urine.
  • Patients undergoing treatment with Furosemide require periodic monitoring of blood pressure, uric acid, plasma electrolytes, creatinine, kidney and liver function, and glucose levels.
  • While taking the drug, you should refuse to drive a vehicle and work with complex mechanisms that require increased concentration and reaction speed.
  • Furosemide solution for intravenous or intramuscular injection should not be mixed in the same syringe with other drugs.

During pregnancy and breastfeeding

Contraindicated during pregnancy and breastfeeding.

In childhood

Contraindicated in children under the age of 3 years.

In old age

It is prescribed with caution to elderly patients.

For impaired renal function

Patients with chronic renal failure require careful selection of the dosage of the drug.

Contraindicated in acute glomerulonephritis and acute renal failure with anuria.

For impaired liver function

It is prescribed with extreme caution to patients with severe liver dysfunction. Requires selection of the dosage of the drug. Contraindicated in patients with severe hepatic insufficiency, with hepatic coma and precoma.

pharmachologic effect

Diuretic, sodium and chloruretic.

Pharmacodynamics and pharmacokinetics

Furosemide - what is it?

Furosemide is a loop diuretic diuretic , which acts mainly on the thick segment of the ascending limb of the loop of Henle. Differs in speed. The diuretic effect is pronounced, but short-lived.

How long does Furosemide take?

After oral administration, the drug begins to act after 20-30 minutes, after infusion into a vein - after 10-15 minutes.

Depending on the characteristics of the body, the effect when using the oral form of Furosemide can persist both for 3-4 and for 6 hours, while it is most powerful after an hour or two after taking the pill.

After the introduction of the solution into the vein, the effect reaches a maximum after half an hour and lasts for 2-8 hours (the more pronounced kidney dysfunction the longer the drug lasts).

Pharmacodynamics

The mechanism of action of the drug is associated with a violation of reabsorption in the tubules of the nephrons of the kidneys of chloride and sodium ions. In addition, Furosemide increases the excretion of magnesium, calcium, phosphates and bicarbonates.

The use of the drug in patients with fromheart failure leads to a decrease in preload on the heart muscle after 20 minutes.

The hemodynamic effect reaches its maximum severity by the 2nd hour of Furosemide action, which is due to a decrease in the tone of the veins, a decrease in BCC (the volume of circulating blood), as well as the volume of fluid filling the intercellular spaces in organs and tissues.

Reduces blood pressure. The effect develops as a consequence:

  • reducing the response of the muscles of the vascular walls to vasoconstrictor (provoking vasoconstriction and a decrease in blood flow in them) exposure;
  • decrease in BCC;
  • increase in excretion sodium chloride .

During the period of action of Furosemide, the excretion of Na + ions increases significantly, however, after the termination of the action of the drug, the rate of their excretion falls below the initial level (“withdrawal” or “rebound” syndrome). Due to this, when administered once a day, it does not have a significant effect on blood pressure and daily excretion of Na.

The reason for this effect is a sharp activation of antinatriuretic links of neurohumoral regulation (in particular, renin-angiotensin) in response to massive diuresis.

The drug stimulates the sympathetic and arginine vasopressive systems, reduces the plasma concentration of atriopeptin, and causes vasoconstriction.

Pharmacokinetics

Absorption from the digestive tract is high, bioavailability (the proportion of absorbed drug) when taken orally is from 60 to 70%. The plasma protein binding rate is 98%.

TSmax when taken per os - 1 hour, when infused into a vein - 0.5 hours.

Furosemide is able to cross the placenta and be excreted in breast milk.

The substance undergoes biotransformation in the liver. Metabolites are secreted into the lumen of the tubules of the kidneys.

T1 / 2 for the oral form of the drug - from one hour to one and a half hours, for parenteral - from half an hour to an hour.

From 60 to 70% of the dose taken orally is excreted by the kidneys, the rest - with faeces. When injected into a vein, about 88% of furosemide and its metabolic products are excreted by the kidneys, with feces - about 12%.

Furosemide indications for use

Furosemide - what are these pills for?

Tablets are prescribed for:

  • edema, the causes of which are pathologies of the kidneys (including nephrotic syndrome ), CHF II-III stage or ;
  • appearing in the form pulmonary edema acute heart failure ;
  • hypertensive crisis (as a monotherapy or in combination with other drugs);
  • severe forms arterial hypertension ;
  • cerebral edema ;
  • hypercalcemia ;
  • eclampsia .

The drug is also used for forced diuresis in case of poisoning with chemicals that are excreted from the body by the kidneys in unchanged form.

With increased blood pressure that develops against the background of chronic renal failure, Furosemide is prescribed if the patient is contraindicated thiazide diuretics , and also if Clcr does not exceed 30 ml per minute).

Indications for use of Furosemide in ampoules

In the annotation for Furosemide in ampoules, the same indications for use are given as for the tablet form of the drug.

With parenteral administration, the drug acts faster than when taken orally. Therefore, doctors answer the question “What is the solution for?”, Answer that the introduction of Furosemide IV allows you to quickly reduce pressure (arterial, in the pulmonary artery, in the left ventricle) and preload on the heart, which is extremely important in emergency conditions (for example , at hypertensive crisis ).

When the drug is prescribed for nephrotic syndrome treatment of the underlying disease should come first.

Furosemide contraindications

The drug is not prescribed for:

  • intolerance to its components;
  • OPN, which is accompanied anuria (if the value of GFR does not exceed 3-5 ml / min.);
  • urethral stenosis ;
  • severe liver failure ;
  • hepatic coma ;
  • hyperglycemic coma ;
  • precomatose states;
  • obstruction of the urinary tract by a calculus;
  • decompensated stenosis of the mitral valve or the mouth of the aorta;
  • conditions in which blood pressure in the right atrium exceeds 10 mm Hg. Art.;
  • hyperuricemia ;
  • (in the acute stage);
  • arterial hypertension ;
  • hypertrophic subaortic stenosis ;
  • violations of water-salt metabolism (hypocalcemia, hypochloremia, hypomagnesemia, etc.);
  • digitalis intoxication (intoxication caused by the intake of cardiac glycosides).

Relative contraindications to the use of Furosemide:

  • benign prostatic hyperplasia (BPH);
  • hypoproteinemia (when taking the drug, the risk of developing ototoxicity increases);
  • obliterating cerebral atherosclerosis ;
  • hepatorenal syndrome ;
  • hypotension in patients at risk of ischemia (coronary, cerebral or otherwise), which is associated with circulatory failure;
  • hypoproteinemia on the background nephrotic syndrome (it is possible to increase the undesirable side effects of Furosemide (especially ototoxicity) and reduce its effectiveness).

Patients at risk should be under constant medical supervision. Violation of the KShchR, hypovolemia or dehydration are grounds for reviewing the treatment regimen and, if necessary, temporarily discontinuing the drug.

Diuretics contribute to the excretion of sodium from the body, therefore, in order to avoid the development hyponatremia before starting therapy and subsequently throughout the entire course of Furosemide, it is necessary to control the sodium level in the patient's blood (especially in patients with cachexia , cirrhosis as well as in the elderly).

Application loop diuretics may cause sudden hypokalemia . The risk group includes:

  • aged people;
  • patients who are not receiving adequate nutrition and / or taking several drugs at the same time;
  • patients diagnosed with cirrhosis with ascites ;
  • patients with heart failure .

hypokalemia raises cardiotoxicity of digitalis preparations (Digitalis) and risk cardiac arrhythmias . At long QT interval syndrome (congenital or drug-induced) hypokalemia contributes to the emergence bradycardia or potentially life-threatening torsades de pointes .

In diabetics throughout the course of treatment, it is necessary to systematically monitor the level of sugar.

Additional Information

The drug is not doping, but it is often used to remove prohibited substances from the body, as well as a means of losing weight in sports where the weight of the athlete is important. In this regard, Furosemide is equated to doping drugs and cannot be used in athletes.

Against the background of the use of the drug, the following side effects may occur:

  • cardiovascular disorders , including orthostatic hypotension , arterial hypotension , arrhythmias , tachycardia , collapse ;
  • dysfunctions of the nervous system manifested by dizziness, muscle weakness, headache, tetany , apathy , adynamia , paresthesia , drowsiness, lethargy, weakness, confusion;
  • sensory dysfunction (in particular, hearing and vision impairments);
  • disorders of the digestive system, including dry mouth, anorexia , cholestatic jaundice diarrhea/constipation, nausea, vomiting, exacerbation ;
  • disorders of the urogenital tract, including oliguria , interstitial nephritis , acute urinary retention (with BPH), hematuria , impotence ;

When furosemide is administered intravenously, it may develop and in newborn babies kidney calcification .

Instructions for use Furosemide

How to take Furosemide for swelling?

Diuretic tablets take inside. The doctor selects the dose individually, depending on the indications and the characteristics of the course of the disease.

An adult with edema that has developed against the background of pathologies of the liver, kidneys or heart is prescribed to take ½-1 tablet / day, if the condition is assessed as moderate. In severe cases, the doctor may recommend taking 2-3 tablets. 1.r./day or 3-4 tab. in 2 doses.

How to lower blood pressure with Furosemide?

To reduce elevated blood pressure in patients with chronic renal failure, the drug is used in combination with antagonists of the renin-angiotensive system. The recommended dose varies from 20 to 120 mg/day. (½-3 tablets / day). The medicine is taken in one or two doses.

Furosemide for weight loss

Some women use the properties of the drug for weight loss. Taking Furosemide tablets (Furosemide Sopharma) really allows you to get rid of several kilograms, but this weight loss can hardly be called weight loss, since the drug does not remove excess fat in problem areas, but only removes water from the body.

Application instruction of Furosemide in ampoules

The preferred method of administering the solution is by slow intravenous injection (performed within 1-2 minutes).

The drug is administered into the muscle in exceptional cases, when the oral or intravenous route of administration is not possible. Contraindications for intramuscular administration of Furosemide are acute conditions (for example, pulmonary edema ).

Taking into account the clinical condition of the patient, it is recommended to transfer from the parenteral to the oral route of administration of Furosemide as soon as possible.

The question of the duration of treatment is decided taking into account the nature of the disease and the severity of the symptoms. The manufacturer recommends using the lowest possible dose at which the therapeutic effect will be maintained.

At edematous syndrome in adults and adolescents over 15 years of age, treatment begins with the introduction into a vein (in exceptional cases - into the muscle) of 20-40 mg of Furosemide.

In the absence of a diuretic effect, the drug is continued to be administered every 2 hours at a dose increased by 50%. Treatment according to this scheme is continued until adequate diuresis is achieved.

A dose greater than 80 mg should be administered by drip into a vein. The rate of administration should not exceed 4 mg/min. The maximum allowable dose is 600 mg / day.

In case of poisoning, to maintain forced diuresis, the patient should be administered from 20 to 40 mg of the drug, after dissolving the required dose in the infusion solution of electrolytes. Further treatment is carried out depending on the volume of diuresis. It is obligatory to replace the salts and fluids lost by the body.

Starting dose at hypertensive crisis - 20-40 mg. In the future, it is adjusted taking into account the clinical response.

Furosemide injections and tablets: instructions for use in children

In pediatrics, the dose is selected depending on the weight of the patient. Furosemide in tablets is given to a child at the rate of 1-2 mg / kg / day. The dose can be taken in one dose or divided into two doses.

The questions of how often you can drink the drug in a particular case, as well as how long the course of treatment will be, can only be answered by the attending physician. Only recommendations on what to take Furosemide with are unequivocal: as an addition to diuretics, you should definitely drink potassium preparations.

Intravenously for children under 15 years of age, the drug is administered at a dose of 0.5-1.5 mg / kg / day.

Furosemide tablets: what are they used for in veterinary medicine?

Why is Furasemide Sopharma used in veterinary medicine? In veterinary practice, Furosemide and similar drugs are used as part of complex therapy for the treatment of heart pathologies in dogs.

The use of diuretics allows you to remove the fluid that accumulates around the lungs, abdominal or chest cavity, and thereby reduce the load on the heart.

For dogs, the dosage of Furosemide depends on the weight of the animal. As a rule, the drug is given 2 times a day at the rate of 2 mg / kg. As an adjunct to treatment, it is recommended that the dog be given bananas daily (one per day) to compensate for potassium losses.

Overdose

Furosemide overdose symptoms:

  • a sharp drop in blood pressure;
  • hypovolemia ;
  • dehydration;
  • collapse ;
  • hemoconcentration ;
  • arrhythmias (including atrioventricular block and fibrillation (flicker) of the ventricles);
  • confusion;
  • drowsiness;
  • arrester with anuria ;
  • apathy;
  • flaccid paralysis.

To normalize the patient's condition, measures are prescribed aimed at correcting the CSR and water-salt metabolism, replenishing the BCC deficiency. Further treatment is symptomatic.

Furosemide has no specific antidote.

Interaction

Furosemide increases concentration and toxicity (in particular, oto- and nephrotoxicity) Ethacrynic acid ,Aminoglycosides , Cephalosporins , , Chloramphenicol , Amphotericin B .

Enhances therapeutic efficacy And Dazoxide , reduces efficiency Allopurine And hypoglycemic drugs .

Reduces the rate of renal excretion of Li + drugs from the blood, thereby increasing the likelihood of intoxication with them.

Enhances induced by non-depolarizing muscle relaxants (peripherally acting relaxants) neuromuscular blockade and action antihypertensive drugs , weakens the effect non-depolarizing relaxants .

In combination with pressor amines, there is a mutual decrease in the effectiveness of drugs, with Amphotericin B and GCS - increases the risk of developing hypokalemia .

Use in combination with cardiac glycosides (SG) can provoke the development of the toxic effects inherent in the latter due to a decrease in the level of potassium in the blood (for low- and high-polarity SGs) and an extension of the half-life (for low-polarity SGs).

Drugs that block tubular secretion increase the serum concentration of furosemide.

Analogues of the parenteral form of the drug: Furosemide-Darnitsa , Furosemide-Vial , Lasix .

Which is better - Lasix or Furosemide?

Lasix is one of the trade names for furosemide. The drug is produced by the Indian company Sanofi India Ltd. and, like its analogue, has two dosage forms: a one-percent solution for injection and tablets of 40 mg.

Thus, when choosing one or another means, one should be guided by subjective feelings. The advantage of Furosemide is its lower price.

furosemide and alcohol

Alcohol is contraindicated in patients taking Furosemide.

Furosemide for weight loss

There is a lot of advice on the Internet about how to use diuretics for weight loss. One of the most affordable drugs in this group is Furosemide.

What does the medicine help? According to the instructions, Furosemide is used for ascites , edematous syndrome , hypertension . Thus, the manufacturer does not report anything regarding the possibility of using diet pills.

However, many women note that with the help of this tool they were able to lose a few kilograms quite quickly (in some cases, up to 3 kg per night). However, it is impossible to regard such weight loss as weight loss: the action of the drug is aimed at removing excess fluid, and by no means at breaking down fat.

Why is furosemide dangerous?

Application diuretics for weight loss can cause serious health problems, because removing water, these drugs also upset the balance of electrolytes in the body. one of the most common side effects is hypokalemia .

Potassium deficiency, in turn, leads to muscle cramps, weakness, visual disturbances, sweating, loss of appetite, nausea, and dizziness.

A very dangerous side effect is arrhythmia . SOLVD studies have shown that treatment loop diuretics accompanied by an increase in mortality among patients. At the same time, both overall and cardiovascular mortality, as well as the number of sudden deaths, are increasing.

Another danger that can be caused by uncontrolled use diuretics for weight loss, is a violation of the kidneys. Moreover, it may take more than one month to restore the function of the kidneys and lymphatic system.

How to take Furosemide for weight loss?

To remove a few extra pounds, women usually take 2-3 (no more!) Furosemide tablets during the day with an interval of three hours between doses, and then 2 more tablets at night.

You can repeat the one-day course no earlier than in 2-3 days.

Furosemide and Asparkam for weight loss

Since one of the side effects of Furosemide is hypokalemia , it is very important to follow a certain diet while using this drug (meaning the use of foods high in potassium) or to additionally take medicines that can minimize the inherent diuretics side effects.

As a rule, Furosemide is recommended to be taken in combination with () . What's happened Asparkam ? This is a drug that is used as an additional source of potassium and magnesium. The drug has a harmless composition, which eliminates the possibility of its undesirable interaction with Furosemide.

Recommendations on how to drink with Asparkam diuretic drugs only a doctor can give. Tablets Asparkama , according to the manufacturer's instructions, take 3-6 pieces per day, dividing the indicated dose into three doses.

How often can Furosemide be taken for weight loss?

Optimal - never. In extreme cases, it is allowed to use the drug as a means of emergency care when you need to urgently remove swelling.

Release form: Solid dosage forms. Tablets.



General characteristics. Composition:

International and chemical names: furosemide;
4-chloro-N-(2-furylmethyl)-5-sulfamoylanthranilic acid;main physical and chemical properties: round tablets, white with a yellowish tint, with a biconvex surface;composition: 1 tablet contains furosemide 40 mg;Excipients: modified corn starch, microcrystalline cellulose, magnesium stearate, povidone, macrogol 6000, lactose monohydrate.


Pharmacological properties:

Pharmacodynamics. A potent diuretic with a rapidly developing effect, a derivative of sulfonamides. The mechanism of action of Furosemide is associated with the blockade of the reabsorption of sodium and chloride ions in the ascending loop of Henle; also affects the convoluted tubules, and this effect is not associated with the inhibition of carbonic anhydrase or aldosterone activity. The drug has a pronounced diuretic, natriuretic, chloruretic effect. It also increases the excretion of potassium, calcium, magnesium. The drug reduces the filling pressure of the left ventricle, pressure in the pulmonary artery, improves heart function during; lowers systemic arterial pressure.
The drug is equally effective in acidosis and alkalosis. The diuretic effect when taken orally is observed after 20-30 minutes, the maximum effect of the drug is after 1-2 hours. The duration of the effect after a single dose is 4 hours or more.

Pharmacokinetics. After oral administration, Furosemide is absorbed from the digestive tract, bioavailability is 64%. The maximum plasma concentration of the drug increases with increasing dose, but the time to reach it does not depend on the dose and varies widely depending on the patient's condition.
Protein binding (mainly albumin) is 95%. Furosemide crosses the placental barrier and is excreted in breast milk. Metabolized in the liver, turning mainly into glucuronide. Furosemide and its metabolites are rapidly excreted by the kidneys. The half-life is 1-1.5 hours. Approximately 50% of the dose taken is excreted in the urine within 24 hours, while during the first 4 hours - 59% of the total drug that is excreted per day. The rest is excreted unchanged in the feces.

Indications for use:

Edematous syndrome of various origins, including chronic heart failure stage IIB-III, liver cirrhosis (portal hypertension syndrome), nephrotic syndrome; ; ; premenstrual tension syndrome; , .


Important! Get to know the treatment

Dosage and administration:

Furosemide is administered orally before meals. Doses are selected depending on the severity of the disease and the severity of the effect. Orally take 40 mg (1 tablet) 1 time per day in the morning. With insufficient action, the dose is increased to 80-160 mg per day (2-3 doses at intervals of 6 hours). After reduction of hypostases appoint in smaller doses with a break of 1-2 days. The maximum daily dose is 160 mg.
With arterial hypertension, the initial dose of the drug for adults is 80 mg per day, divided into 2 doses. It must match the condition of the patient. With insufficient effect, it should be prescribed together with other antihypertensive drugs.
With concomitant heart failure, the daily dose can be increased to 80 mg.
For children aged 3 years and older, the average daily dose taken orally during or after meals is 4-3 mg/kg in 1-4 doses. Furosemide has the greatest diuretic effect in the first 3-5 days of administration. After the disappearance of edema, they switch to an intermittent appointment of Furosemide - every other day or 1-2 times a week.
If the child has not previously received furosemide or other diuretics, do not immediately prescribe a diuretic in the average daily dose. First, it is necessary to apply a diuretic at a dose of ¼ - ½ of the average daily dose, and then, if there is no diuretic effect, the dose should be increased. For children, the initial dose is 2 mg / kg, if necessary, it can be increased by 1-2 mg / kg.

Application Features:

The drug is prescribed with caution in severe cardiovascular insufficiency, with prolonged therapy with cardiac glycosides, in elderly patients with severe atherosclerosis. Serious electrolyte disturbances should be corrected prior to starting treatment.
During treatment, it is necessary to control the level of electrolytes, carbonates, urea.
Treatment should be carried out against the background of a potassium-rich diet.
During pregnancy in the first half, the drug is contraindicated; in the second half, Furosemide can be used only according to strict indications and for a short time, which is determined by the doctor.
If it is necessary to take Furosemide during lactation, breastfeeding should be discontinued, since the drug may pass into breast milk (and also inhibit lactation).
When using the drug, it is impossible to exclude a decrease in attention, which is important for drivers and people working with mechanisms.
If oliguria persists for 24 hours, furosemide should be discontinued.
To avoid the “rebound” syndrome in hypertension, furosemide is prescribed at least 2 times a day.

Side effects:

Possible, hypovolemia, dehydration, hyperemia, itching of the skin, hypotension, cardiac arrhythmias, reversible hearing loss, vision, interstitial. Due to increased diuresis, there may be,; muscle weakness, thirst, dehydration, hypochloremia, metabolic; transient, uricosuria, exacerbation, in some cases, deterioration in obstructive uropathy. As soon as side effects appear, the dose of Furosemide must be reduced or discontinued.

Interaction with other drugs:

With the simultaneous use of Furosemide with cardiac glycosides, the risk of developing glycoside intoxication increases, and when combined with glucocorticoid agents, the risk of developing hypokalemia.
Furosemide potentiates the action of muscle relaxants, antihypertensive drugs. With simultaneous use with aminoglycosides, cephalosporins and cisplatin, their concentration in blood plasma may increase, which can lead to the development of nephro- and ototoxic effects.
Non-steroidal anti-inflammatory drugs may reduce the diuretic effect of Furosemide.
With simultaneous use with Furosemide, the effect of hypoglycemic drugs may be weakened. The simultaneous use of Furosemide with lithium preparations can lead to increased reabsorption of lithium in the renal tubules and the appearance of a toxic effect.
Probenecid increases the concentration in the blood. with obstruction of the outgoing tract of the left ventricle, lupus erythematosus. Children's age up to 3 years.

pharmachologic effect

"Loop" diuretic. Violates the reabsorption of sodium ions, chlorine in the thick segment of the ascending part of the loop of Henle. Due to the increase in the release of sodium ions, there is a secondary (mediated by osmotically bound water) increased excretion of water and an increase in the secretion of potassium ions in the distal part of the renal tubule. At the same time, the excretion of calcium and magnesium ions increases. It has secondary effects due to the release of intrarenal mediators and the redistribution of intrarenal blood flow. Against the background of course treatment, there is no weakening of the effect. In heart failure, it quickly leads to a decrease in the preload on the heart through the expansion of large veins. It has a hypotensive effect due to an increase in the excretion of sodium chloride and a decrease in the response of vascular smooth muscles to vasoconstrictor effects and as a result of a decrease in BCC. The action of furosemide after intravenous administration occurs within 5-10 minutes; after oral administration - after 30-60 minutes, the maximum effect - after 1-2 hours, the duration of the effect - 2-3 hours (with reduced kidney function - up to 8 hours). During the period of action, the excretion of sodium ions increases significantly, however, after its termination, the rate of excretion decreases below the initial level ("rebound" or "cancellation" syndrome). The phenomenon is caused by a sharp activation of renin-angiotensin and other antinatriuretic neurohumoral regulation in response to massive diuresis; stimulates the arginine-vasopressive and sympathetic systems. Reduces the level of atrial natriuretic factor in plasma, causes vasoconstriction. Due to the "rebound" phenomenon, when taken once a day, it may not have a significant effect on the daily excretion of sodium ions and blood pressure. When administered intravenously, it causes dilatation of peripheral veins, reduces preload, reduces left ventricular filling pressure and pulmonary artery pressure, as well as systemic blood pressure. The diuretic effect develops 3-4 minutes after the on / in the introduction and lasts 1-2 hours; after oral administration - after 20-30 minutes, lasts up to 4 hours.

Pharmacokinetics

Absorption is high, Cmax is noted in the blood plasma when taken orally after 1 hour. Bioavailability is 60-70%. Relative Vd - 0.2 l / kg. Binding to plasma proteins - 98%. Penetrates through the placental barrier, excreted in breast milk. Metabolized in the liver to form 4-chloro-5-sulfamoylanthranilic acid. It is secreted into the lumen of the renal tubules through the anion transport system existing in the proximal nephron. It is excreted mainly (88%) by the kidneys unchanged and in the form of metabolites; the rest is the intestines. T1 / 2 - 1-1.5 hours. Features of pharmacokinetics in certain groups of patients In renal failure, the excretion of furosemide slows down, and T1 / 2 increases; with severe renal insufficiency, the final T1 / 2 may increase up to 24 hours. In nephrotic syndrome, a decrease in plasma protein concentrations leads to an increase in the concentrations of unbound furosemide (its free fraction), and therefore, the risk of developing an ototoxic effect increases. On the other hand, the diuretic effect of furosemide in these patients may be reduced due to binding of furosemide to tubular albumin and reduced tubular secretion of furosemide. With hemodialysis, peritoneal dialysis and continuous ambulatory peritoneal dialysis, furosemide is excreted insignificantly. In hepatic insufficiency, T1 / 2 of furosemide increases by 30-90%, mainly due to an increase in the relative volume of distribution. Pharmacokinetic parameters in this category of patients can vary greatly. In heart failure, severe arterial hypertension and in elderly patients, the excretion of furosemide slows down due to a decrease in renal function.

Special conditions

Before starting therapy with Furosemide Sopharma, the presence of severe urinary outflow disorders should be excluded, patients with a partial violation of the outflow of urine need to be carefully monitored. Against the background of course treatment, it is necessary to periodically monitor blood pressure, the content of electrolytes in blood plasma (including sodium, calcium, potassium, magnesium ions), acid-base state, residual nitrogen, creatinine, uric acid, liver function and, if necessary, carry out appropriate treatment adjustment. The use of furosemide slows down the excretion of uric acid, which can provoke an exacerbation of the course of gout. Patients with hypersensitivity to sulfonamides and sulfonylurea derivatives may have cross-sensitivity to furosemide. In patients receiving high doses of furosemide, in order to avoid the development of hyponatremia and metabolic alkalosis, it is not advisable to limit the intake of table salt. For the prevention of hypokalemia, the simultaneous administration of potassium preparations and potassium-sparing diuretics is recommended, as well as a diet rich in potassium. The selection of the dosage regimen for patients with ascites against the background of liver cirrhosis should be carried out in stationary conditions (disturbances in the water and electrolyte balance can lead to the development of hepatic coma). This category of patients shows regular monitoring of plasma electrolytes. With the appearance or increase of azotemia and oliguria in patients with severe progressive kidney disease, it is recommended to suspend treatment. In patients with diabetes mellitus or with reduced glucose tolerance, periodic monitoring of the level of glucose concentration in the blood and urine is required. In patients who are unconscious, with benign prostatic hyperplasia, narrowing of the ureters or hydronephrosis, control of urination is necessary due to the possibility of acute urinary retention. This medicinal product contains lactose monohydrate, therefore patients with rare hereditary problems of galactose intolerance, the lapp lactase deficiency or glucose-galactose malabsorption should not take this medicinal product. The composition of the drug includes wheat starch in an amount that is safe for use in patients with celiac disease (gluten enteropathy). Patients with wheat allergy (other than celiac disease) should not use this medicine. Influence on the ability to drive vehicles and control mechanisms During the period of treatment with Furosemide Sopharma, one should avoid engaging in potentially hazardous activities that require increased attention and speed of psychomotor reactions (driving vehicles and working with mechanisms). Overdose Symptoms: pronounced decrease in blood pressure, collapse, shock, hypovolemia, dehydration, hemoconcentration, arrhythmias (including AV blockade, ventricular fibrillation), acute renal failure with anuria, thrombosis, thromboembolism, drowsiness, confusion, flaccid paralysis, apathy. Treatment: correction of water and electrolyte balance and acid-base balance, replenishment of circulating blood volume, gastric lavage, activated charcoal, symptomatic treatment. There is no specific antidote.

drug interaction

Combinations that are not recommended Co-administration of furosemide and chloral hydrate is not recommended. The ototoxicity of aminoglycosides and other ototoxic drugs may be increased by concomitant use of furosemide. Such combinations should be avoided, as the resulting hearing loss may be irreversible. An exception is the use of this combination for health reasons. Combinations Requiring Special Precautions If forced diuresis with furosemide is required during treatment with cisplatin, furosemide may be given at low doses (up to 40 mg) with normal renal function and no fluid deficit. Otherwise, it is possible to increase the nephrotoxic effect of cisplatin. Furosemide reduces the excretion of lithium, thereby increasing the toxic effects of lithium on the heart and nervous system. Lithium levels should be monitored in patients receiving this combination. Treatment with furosemide can lead to severe hypotension and deterioration of renal function, and in some cases to the development of acute renal failure, especially when prescribing angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor antagonists (sartans) at the first dose or at higher doses. It is necessary to cancel furosemide, or reduce its dose 3 days before the use of ACE inhibitors or sartans. Furosemide should be used with caution in combination with risperidone, as mortality may be increased in elderly patients. The need for joint use must be justified taking into account the risks and benefits of this combination. The risk of mortality increases in the presence of dehydration. Significant interactions of furosemide and other drugs. The simultaneous administration of non-steroidal anti-inflammatory drugs (NSAIDs), including acetylsalicylic acid, may reduce the effect of furosemide. In patients with dehydration or hypovolemia, NSAIDs can cause acute renal failure. The toxic effect of salicylates may increase. Perhaps a decrease in the effectiveness of furosemide with the simultaneous appointment of phenytoin. With the simultaneous use of glucocorticosteroids, carbenoxolone, licorice in large quantities, and prolonged use of laxatives, hypokalemia may increase. Hypokalemia or hypomagnesemia may increase myocardial sensitivity to cardiac glycosides and drugs that prolong the QT interval. The effect of drugs that lower blood pressure (antihypertensive, diuretic and other drugs) can be enhanced when used simultaneously with furosemide. Simultaneous use of probenecid, methotrexate and other drugs that are excreted by tubular secretion may reduce the effectiveness of furosemide. Furosemide can lead to a decrease in the excretion of these drugs. It is possible to increase their levels in the blood serum and increase the risk of side effects. The effectiveness of hypoglycemic agents and vasoconstrictive amines (epinephrine / adrenaline, norepinephrine / norepinephrine) may be weakened, and theophylline and curariform agents - enhanced. Furosemide may increase the damaging effect on the kidneys of nephrotoxic drugs. In patients receiving concomitant treatment with furosemide and individual cephalosporins in high doses, deterioration in renal function is possible. With the simultaneous use of cyclosporine A and furosemide, there may be an increased risk of developing secondary gouty arthritis due to furosemide-induced hyperuricemia and deterioration in the excretion of urate by the kidneys caused by cyclosporine. Patients with a high risk of developing nephropathy, when using furosemide in conjunction with radiopaque agents, are more susceptible to impaired renal function. When used in conjunction with thiazides, photosensitivity reactions may develop. In the event of an unexpected photosensitivity reaction when taking furosemide, it is recommended to stop therapy. If repeated administration is necessary, ultraviolet radiation or solar insolation should be avoided.

pharmachologic effect

Diuretic, sodium and chloruretic.

Pharmacodynamics and pharmacokinetics

Furosemide - what is it?

Furosemide is a "loop" diuretic diuretic , which acts mainly on the thick segment of the ascending limb of the loop of Henle. Differs in speed. The diuretic effect is pronounced, but short-lived.

How long does Furosemide take?

After oral administration, the drug begins to act after 20-30 minutes, after infusion into a vein - after 10-15 minutes.

Depending on the characteristics of the body, the effect when using the oral form of Furosemide can persist both for 3-4 and for 6 hours, while it is most powerful after an hour or two after taking the pill.

After the introduction of the solution into the vein, the effect reaches a maximum after half an hour and lasts for 2-8 hours (the more pronounced kidney dysfunction the longer the drug lasts).

Pharmacodynamics

The mechanism of action of the drug is associated with a violation of reabsorption in the tubules of the nephrons of the kidneys of chloride and sodium ions. In addition, Furosemide increases the excretion of magnesium, calcium, phosphates and bicarbonates.

The use of the drug in patients with fromheart failure leads to a decrease in preload on the heart muscle after 20 minutes.

The hemodynamic effect reaches its maximum severity by the 2nd hour of Furosemide action, which is due to a decrease in the tone of the veins, a decrease in BCC (the volume of circulating blood), as well as the volume of fluid filling the intercellular spaces in organs and tissues.

Reduces blood pressure. The effect develops as a consequence:

  • reducing the response of the muscles of the vascular walls to vasoconstrictor (provoking vasoconstriction and a decrease in blood flow in them) exposure;
  • decrease in BCC;
  • increase in excretion sodium chloride .

During the period of action of Furosemide, the excretion of Na + ions increases significantly, however, after the termination of the action of the drug, the rate of their excretion falls below the initial level (“withdrawal” or “rebound” syndrome). Due to this, when administered once a day, it does not have a significant effect on blood pressure and daily excretion of Na.

The reason for this effect is a sharp activation of antinatriuretic links of neurohumoral regulation (in particular, renin-angiotensin) in response to massive diuresis.

The drug stimulates the sympathetic and arginine vasopressive systems, reduces the plasma concentration of atriopeptin, and causes vasoconstriction.

Pharmacokinetics

Absorption from the digestive tract is high, bioavailability (the proportion of absorbed drug) when taken orally is from 60 to 70%. The plasma protein binding rate is 98%.

TSmax when taken per os - 1 hour, when infused into a vein - 0.5 hours.

Furosemide is able to cross the placenta and be excreted in breast milk.

The substance undergoes biotransformation in the liver. Metabolites are secreted into the lumen of the tubules of the kidneys.

T1 / 2 for the oral form of the drug - from one hour to one and a half hours, for parenteral - from half an hour to an hour.

From 60 to 70% of the dose taken orally is excreted by the kidneys, the rest - with faeces. When injected into a vein, about 88% of furosemide and its metabolic products are excreted by the kidneys, with feces - about 12%.

Furosemide indications for use

Furosemide - what are these pills for?

Tablets are prescribed for:

  • edema, the causes of which are pathologies of the kidneys (including nephrotic syndrome ), CHF II-III stage or cirrhosis of the liver ;
  • appearing in the form pulmonary edema acute heart failure ;
  • hypertensive crisis (as a monotherapy or in combination with other drugs);
  • severe forms arterial hypertension ;
  • cerebral edema ;
  • hypercalcemia ;
  • eclampsia .

The drug is also used for forced diuresis in case of poisoning with chemicals that are excreted from the body by the kidneys in unchanged form.

With increased blood pressure that develops against the background of chronic renal failure, Furosemide is prescribed if the patient is contraindicated thiazide diuretics , and also if Clcr does not exceed 30 ml per minute).

Indications for use of Furosemide in ampoules

In the annotation for Furosemide in ampoules, the same indications for use are given as for the tablet form of the drug.

With parenteral administration, the drug acts faster than when taken orally. Therefore, doctors answer the question “What is the solution for?”, Answer that the introduction of Furosemide IV allows you to quickly reduce pressure (arterial, in the pulmonary artery, in the left ventricle) and preload on the heart, which is extremely important in emergency conditions (for example , at hypertensive crisis ).

When the drug is prescribed for nephrotic syndrome treatment of the underlying disease should come first.

Furosemide contraindications

The drug is not prescribed for:

  • intolerance to its components;
  • OPN, which is accompanied anuria (if the value of GFR does not exceed 3-5 ml / min.);
  • urethral stenosis ;
  • severe liver failure ;
  • hepatic coma ;
  • hyperglycemic coma ;
  • precomatose states;
  • obstruction of the urinary tract by a calculus;
  • decompensated stenosis of the mitral valve or the mouth of the aorta;
  • conditions in which blood pressure in the right atrium exceeds 10 mm Hg. Art.;
  • gout ;
  • hyperuricemia ;
  • myocardial infarction (in the acute stage);
  • arterial hypertension ;
  • hypertrophic subaortic stenosis ;
  • systemic lupus erythematosus ;
  • violations of water-salt metabolism (hypocalcemia, hypochloremia, hypomagnesemia, etc.);
  • pancreatitis ;
  • digitalis intoxication (intoxication caused by the intake of cardiac glycosides).

Relative contraindications to the use of Furosemide:

  • benign prostatic hyperplasia (BPH);
  • diabetes ;
  • hypoproteinemia (when taking the drug, the risk of developing ototoxicity increases);
  • obliterating cerebral atherosclerosis ;
  • hepatorenal syndrome ;
  • hypotension in patients at risk of ischemia (coronary, cerebral or otherwise), which is associated with circulatory failure;
  • hypoproteinemia on the background nephrotic syndrome (it is possible to increase the undesirable side effects of Furosemide (especially ototoxicity) and reduce its effectiveness).

Patients at risk should be under constant medical supervision. Violation of the KShchR, hypovolemia or dehydration are grounds for reviewing the treatment regimen and, if necessary, temporarily discontinuing the drug.

Diuretics contribute to the excretion of sodium from the body, therefore, in order to avoid the development hyponatremia before starting therapy and subsequently throughout the entire course of Furosemide, it is necessary to control the sodium level in the patient's blood (especially in patients with cachexia , cirrhosis as well as in the elderly).

Application loop diuretics may cause sudden hypokalemia . The risk group includes:

  • aged people;
  • patients who are not receiving adequate nutrition and / or taking several drugs at the same time;
  • patients diagnosed with cirrhosis with ascites ;
  • patients with heart failure .

hypokalemia raises cardiotoxicity of digitalis preparations (Digitalis) and risk cardiac arrhythmias . At long QT interval syndrome (congenital or drug-induced) hypokalemia contributes to the emergence bradycardia or potentially life-threatening torsades de pointes .

In diabetics throughout the course of treatment, it is necessary to systematically monitor the level of sugar.

Additional Information

The drug is not doping, but it is often used to remove prohibited substances from the body, as well as a means of losing weight in sports where the weight of the athlete is important. In this regard, Furosemide is equated to doping drugs and cannot be used in athletes.

Side effects of furosemide

Against the background of the use of the drug, the following side effects may occur:

  • cardiovascular disorders , including orthostatic hypotension , arterial hypotension , arrhythmias , tachycardia , collapse ;
  • dysfunctions of the nervous system manifested by dizziness, muscle weakness, headache, tetany , apathy , adynamia , paresthesia , drowsiness, lethargy, weakness, confusion;
  • sensory dysfunction (in particular, hearing and vision impairments);
  • disorders of the digestive system, including dry mouth, anorexia , cholestatic jaundice diarrhea/constipation, nausea, vomiting, exacerbation of pancreatitis ;
  • disorders of the urogenital tract, including oliguria , interstitial nephritis , acute urinary retention (with BPH), hematuria , impotence ;

When furosemide is administered intravenously, it may develop thrombophlebitis and in newborn babies kidney calcification .

Instructions for use Furosemide

How to take Furosemide for swelling?

Diuretic tablets take inside. The doctor selects the dose individually, depending on the indications and the characteristics of the course of the disease.

An adult with edema that has developed against the background of pathologies of the liver, kidneys or heart is prescribed to take ½-1 tablet / day, if the condition is assessed as moderate. In severe cases, the doctor may recommend taking 2-3 tablets. 1.r./day or 3-4 tab. in 2 doses.

How to lower blood pressure with Furosemide?

To reduce elevated blood pressure in patients with chronic renal failure, the drug is used in combination with antagonists of the renin-angiotensive system. The recommended dose varies from 20 to 120 mg/day. (½-3 tablets / day). The medicine is taken in one or two doses.

Furosemide for weight loss

Some women use the properties of the drug for weight loss. Taking Furosemide tablets (Furosemide Sopharma) really allows you to get rid of several kilograms, but this weight loss can hardly be called weight loss, since the drug does not remove excess fat in problem areas, but only removes water from the body.

Application instruction of Furosemide in ampoules

The preferred method of administering the solution is by slow intravenous injection (performed within 1-2 minutes).

The drug is administered into the muscle in exceptional cases, when the oral or intravenous route of administration is not possible. Contraindications for intramuscular administration of Furosemide are acute conditions (for example, pulmonary edema ).

Taking into account the clinical condition of the patient, it is recommended to transfer from the parenteral to the oral route of administration of Furosemide as soon as possible.

The question of the duration of treatment is decided taking into account the nature of the disease and the severity of the symptoms. The manufacturer recommends using the lowest possible dose at which the therapeutic effect will be maintained.

At edematous syndrome in adults and adolescents over 15 years of age, treatment begins with the introduction into a vein (in exceptional cases, into a muscle) of 20-40 mg of Furosemide.

In the absence of a diuretic effect, the drug is continued to be administered every 2 hours at a dose increased by 50%. Treatment according to this scheme is continued until adequate diuresis is achieved.

A dose greater than 80 mg should be administered by drip into a vein. The rate of administration should not exceed 4 mg/min. The maximum allowable dose is 600 mg / day.

In case of poisoning, to maintain forced diuresis, the patient should be administered from 20 to 40 mg of the drug, after dissolving the required dose in the infusion solution of electrolytes. Further treatment is carried out depending on the volume of diuresis. It is obligatory to replace the salts and fluids lost by the body.

Starting dose at hypertensive crisis - 20-40 mg. In the future, it is adjusted taking into account the clinical response.

Furosemide injections and tablets: instructions for use in children

In pediatrics, the dose is selected depending on the weight of the patient. Furosemide in tablets is given to a child at the rate of 1-2 mg / kg / day. The dose can be taken in one dose or divided into two doses.

The questions of how often you can drink the drug in a particular case, as well as how long the course of treatment will be, can only be answered by the attending physician. Only recommendations on what to take Furosemide with are unequivocal: as an addition to diuretics, you should definitely drink potassium preparations.

Intravenously for children under 15 years of age, the drug is administered at a dose of 0.5-1.5 mg / kg / day.

Furosemide tablets: what are they used for in veterinary medicine?

Why is Furasemide Sopharma used in veterinary medicine? In veterinary practice, Furosemide and similar drugs are used as part of complex therapy for the treatment of heart pathologies in dogs.

The use of diuretics allows you to remove the fluid that accumulates around the lungs, abdominal or chest cavity, and thereby reduce the load on the heart.

For dogs, the dosage of Furosemide depends on the weight of the animal. As a rule, the drug is given 2 times a day at the rate of 2 mg / kg. As an adjunct to treatment, it is recommended that the dog be given bananas daily (one per day) to compensate for potassium losses.

Overdose

Furosemide overdose symptoms:

  • a sharp drop in blood pressure;
  • hypovolemia ;
  • dehydration;
  • collapse ;
  • hemoconcentration ;
  • arrhythmias (including atrioventricular block and fibrillation (flicker) of the ventricles);
  • thrombosis ;
  • thromboembolism ;
  • confusion;
  • drowsiness;
  • arrester with anuria ;
  • apathy;
  • flaccid paralysis.

To normalize the patient's condition, measures are prescribed aimed at correcting the CSR and water-salt metabolism, replenishing the BCC deficiency. Further treatment is symptomatic.

Furosemide has no specific antidote.

Interaction

Furosemide increases concentration and toxicity (in particular, oto- and nephrotoxicity) Ethacrynic acid , Aminoglycosides , Cephalosporins , Cisplatin , Chloramphenicol , Amphotericin B .

Enhances therapeutic efficacy Theophylline And Dazoxide , reduces efficiency Allopurine And hypoglycemic drugs .

Reduces the rate of renal excretion of Li + drugs from the blood, thereby increasing the likelihood of intoxication with them.

Enhances induced by non-depolarizing muscle relaxants (peripherally acting relaxants) neuromuscular blockade and action antihypertensive drugs , weakens the effect non-depolarizing relaxants .

In combination with pressor amines, there is a mutual decrease in the effectiveness of drugs, with Amphotericin B and GCS - increases the risk of developing hypokalemia .

Use in combination with cardiac glycosides (SG) can provoke the development of the toxic effects inherent in the latter due to a decrease in the level of potassium in the blood (for low- and high-polarity SGs) and an extension of the half-life (for low-polarity SGs).

Drugs that block tubular secretion increase the serum concentration of furosemide.

Sucralfate and NSAIDs reduce the diuretic effect of the drug due to the suppression of Pg synthesis, changes in plasma concentration renin and allocation aldosterone .

The use of high doses salicylates against the background of drug treatment increases the risk of manifestation of their toxicity, which is due to competitive renal excretion of drugs.

The Furosemide solution injected into a vein has a slightly alkaline reaction, so it is contraindicated to mix it with drugs whose pH is below 5.5.

Furosemide intravenously within 24 hours of chloral hydrate can cause:

  • nausea;
  • flushes of blood;
  • anxiety;
  • increased sweating;
  • increase in blood pressure;
  • tachycardia.

The use of Furosemide with ototoxic agents (for example, with aminoglycosides ) can cause irreversible hearing loss . Such a combination can only be used for health reasons.

Reviews about Furosemide

Furasemide is one of the most effective diuretics fast and short action.

Reviews of doctors confirm the fact that the drug plays a key role in the treatment edematous syndrome in patients with heart failure , insofar as loop diuretics most effectively block the reabsorption of Na + ions in the ascending segment of the loop of Henle. At the same time, Furosemide retains its activity even in patients with chronic renal failure (including those at the terminal stage of the disease).

However, the application loop diuretics short-acting may cause irreversible damage to the renal tubules, especially in cases where the drug is administered in high doses.

Parallel increase in the delivery of Na + ions to the distal parts of the nephron, where they no longer act loop diuretics , leads to sodium overload and structural damage to these parts of the nephron with the development hyperplasia And hypertrophy .

In addition, after the completion of the action of the drug, the reabsorption of Na + increases significantly and, as a result, the “rebound” effect develops, which is manifested by an increase in postdiuretic reabsorption.

The reviews that patients leave allow us to conclude that the medicine helps well with edema and is indispensable for hypertensive patients. The disadvantages of the drug, as a rule, are called side effects, contraindications and the fact that it is addictive.

Another category of reviews is reviews of Furosemide for weight loss.

Thus, given that Furosemide is a very powerful tool, it can be used only subject to contraindications, without exceeding the prescribed dose and only under the supervision of a doctor (especially during pregnancy). Also, you should not take it for other purposes (for example, when cystitis ).

During treatment diuretics very important is the question - with what to drink the drug. It is optimal to supplement therapy with the use of potassium-rich foods or taking potassium supplements.
