What is dangerous Furosemide: adverse reactions, harm to the body, consequences. Furosemide instructions for use, contraindications, side effects, reviews Furosemide 40mg

Furosemide for weight loss is a very popular method that allows you to get rid of extra pounds in a couple of days. The number of drugs that are used for these purposes is huge, but this diuretic is considered the most accessible and well-known. In medical practice, Furosemide has been used for a long time, so all its positive aspects and side effects have been well studied. According to the reviews of losing weight, Furosemide helps to lose weight perfectly when it appears as a result of fluid retention in the body.

Can Furosemide Help You Lose Weight?

Before studying the question of how to drink Furosemide for weight loss, you need to find out how effective the drug is. The composition of the tablets, in addition to the main component, contains: potato starch, magnesium stearate and milk sugar. A diuretic (a group of diuretics) increases urine production. This process helps to draw additional fluid from the tissues, so the medicine is prescribed for people suffering from kidney, liver, cardiovascular pathologies, and not for being overweight.

A side effect of treatment with Furosemide is weight loss, but this is only a temporary effect. Fat deposits remain in place, only water leaves, which, after the abolition of the diuretic, will return again. For this reason, you should not rely solely on Furosemide if you want to get rid of a few excess weight. The drug will help only for a short period of time, so it is better to use it as an express method, but first you need to consult a specialist.

How does Furosemide work on excess weight?

According to the instructions for use, Furosemide diuretic tablets for weight loss are not used. However, reviews of those who are losing weight about this drug claim that its periodic use allows you to control weight and keep your figure normal. Just one tablet of Furosemide after a stormy feast helps to avoid swollen legs and a swollen face in the morning, which means you can seem slim and fresh at work. But do not think that this medicine is a panacea for weight loss. Furosemide is a very powerful drug that should be used as directed by a doctor.

The main plus of Furosemide is the ability to instantly start the withdrawal of water. Already two hours after taking the pill, excess fluid begins to be released from the body. However, along with it, useful substances also leave: vitamins, trace elements, especially calcium, iron, sodium, magnesium, and potassium. The result of such weight loss can be deplorable for health. The heart suffers first, as its work becomes difficult due to a lack of potassium and magnesium, then the muscles lose their tone. It may take several weeks to restore the normal functioning of the body after taking Furosemide for weight loss.

Contraindications for use

Weight loss with Furosemide is contraindicated during pregnancy and lactation. Also, the medication should be abandoned in the presence of the following conditions:

• diabetes;
• gout;
• pancreatitis;
• violation of water-salt metabolism;
• obstruction of the urinary tract;
• kidney or liver failure;
• hypersensitivity to sulfonamides.

How to take Furosemide for weight loss

As already mentioned, if you take Furosemide to lose weight without dieting and exercise, then the effect will not be long-lasting. The lost fluid, respectively, and the initial weight, will return in two days. Taking Furosemide for weight loss requires strict adherence to the dosage. It is advisable to drink no more than 1-3 tablets per day (depending on weight) with a break of 3-4 hours. If Furosemide is selected in ampoules, then it must be administered intravenously for two minutes (dose 2-4 ml). If it is impossible to administer the drug into a vein, an intramuscular method can be used.

Doctors strongly recommend a one-day daily intake of the drug for weight loss. If there are no side effects, then if necessary, Furosemide tablets can be used for two days in a row. In order not to harm the body, you should follow some rules:

1. Salt should be excluded from the diet, otherwise, in combination with Furosemide, weight loss can lead to dehydration.
2. When combining a diuretic with other drugs, you should carefully read the instructions, because if they are incompatible, their effectiveness is reduced.
3. It is necessary to increase the amount of water consumed to 2-3 liters per day.
4. It is advisable to include natural products with a diuretic effect in the diet: oats, lemon and cranberry juice, beets, celery, carrots and other natural diuretics.

Side effects

The body can react to the action of diuretic tablets with unwanted side reactions. Uncontrolled intake of Furosemide for weight loss can provoke disturbances in the work of the following systems and organs:

• Heart, blood vessels and circulatory system: arrhythmia, tachycardia, lowering blood pressure, dizziness, convulsions.
• Genitourinary system: decreased potency, urinary retention, nephritis, oliguria.
• Sense organs: dry mouth, blurred vision, hearing loss.
• Skin: itching, rashes, redness.
• Digestive system: nausea, vomiting, diarrhea, constipation.

Why should Furosemide and Asparkam be taken together?

Asparkam is a medicine designed to improve metabolic processes in the body. The drug is prescribed to restore the balance of electrolytes, to quickly move potassium and magnesium ions into tissue cells. The agent has an antiarrhythmic effect, reduces myocardial excitability, improves blood circulation.

When losing weight with the diuretic Furosemide, beneficial substances leave the body. In order for them to be quickly replenished, the lost resources will help to return Asparkam's reception. It is desirable to take the medicine in the same dosage, at the same time and with the same course as Furosemide.

The opinion of doctors about the drug

Doctors say that powerful diuretics, such as Furosemide, are prescribed exclusively for pathologies of the liver, kidneys or heart, in order to get rid of painful swelling. The instructions for use of the drug do not say anything about losing weight, so using the medicine for this purpose is not only useless, but also dangerous.

In case of an overdose, all systems can suffer. The consequences of taking Furosemide can lead to symptoms of diseases of the nervous, digestive, genitourinary and cardiovascular systems. For men, such weight loss can result in impotence. Furosemide should be taken strictly under the supervision of the attending physician.

Edema, which have either renal or cardiac origin, are life threatening.

Their appearance affects the well-being and general condition, which is very important for the full functioning of not only all systems of internal organs, but also parts of the body.

The drug "Furosemide" was developed by experienced pharmacists to relieve edema.

The medicine provides a fairly effective result.

Indications for use

Indications for the use of "Furosemide" is the presence of the following symptoms:

• edema of cardiac or renal origin;
• high blood pressure, which accompanies chronic renal failure.

Way

Given medicine should be taken orally. In this case, the dose is determined by the severity of the disease, as well as the period of its course.

With edema of cardiac, renal or hepatic origin, adults are prescribed the drug in the following doses:

• in moderate condition ½-1 tablet per day;
• in serious condition, 2-3 tablets per day. Reception can be carried out in one or two calls. In addition, in some cases, 3-4 tablets per day are prescribed in two divided doses.
• With significantly elevated blood pressure in patients suffering from chronic renal failure, Furosemide is usually used in combination with other antihypertensive drugs, the daily dose of which usually does not exceed 120 mg.

For the treatment of edema in young children the daily dose is 1-2 mg/kg of body weight. Tablets should be taken in 1-2 doses.

Release form and composition

This drug is available in the form of tablets of 40 mg. They differ in white color with a characteristic light cream tint. Tablets have a flat-cylindrical shape.

The composition of the medicine includes:

active ingredient.
1. Additional substances: magnesium stearate, milk sugar, starch 1500 and potato starch.

Interaction with other drugs

With the combined use of "Furosemide" with other medications necessary for the complex treatment of a particular disease, various side effects may occur:

1. Toxic drugs, as well as "Aminoglycoside" often leads to irreversible hearing loss.
2. "Cisplatin" - the nephrotoxic effect is enhanced.
3. It is forbidden to take "Furosemide" with drugs that are intended to slow down the excretion of lithium from the human body.
4. Angiotensin II receptor antagonists, as well as angiotensin-converting enzyme inhibitors - a sharp deterioration in kidney function, as well as the occurrence of kidney failure.
5. "Risperidone" - significantly increases the mortality rate of elderly patients.
6. Non-steroidal anti-inflammatory drugs - worsens the effectiveness of the drug "Furosemide". In some patients, the development of acute renal failure or an increase in the toxic effect characteristic of salicylates is observed.
7. "Phenytoin" slows down the action of "Furosemide".
8. "Carbenoxolone", "Licorice", as well as glucocorticosteroids - hypokalemia.

Side effects

Furosemide is strictly prohibited for the treatment of people with the following symptoms and diseases:

1. Diabetes.
2. Benign prostatic hyperplasia.
3. Hypotension.
4. Atherosclerosis of the cerebral arteries.
5. Hypoproteinemia.
6. hepatorenal syndrome.

Side effects

When taking "Furosemide" manifestations of various side effects are possible:

It is allowed to take "Furosemide" during the entire first trimester of the disease. During the further period of bearing a child, this drug is allowed to be administered to a woman only if there are vital indications.

Furosemide is a so-called "loop" diuretic. Loop, because the violation of the reabsorption of sodium and chlorine ions caused by it is localized in the ascending part of the loop of Henle. Due to an increase in the excretion of sodium ions, there is an increased, osmotically related excretion of water and potassium, calcium and magnesium ions. With insufficient heart function, the drug quickly reduces the preload on the myocardium by increasing the lumen of large veins. It has an antihypertensive effect due to the intensive excretion of sodium and chlorine ions, a decrease in the volume of circulating blood and a decrease in the sensitivity of the vascular walls to vasoconstrictor factors. The effect of the drug after intravenous administration occurs after 5-10 minutes, after oral administration - after 30-60 minutes. The peak activity of furosemide is noted after 1-2 hours, the duration of action is 2-3 hours (with renal failure - up to 8 hours). The drug is characterized by a withdrawal syndrome: after the termination of its action, the rate of excretion of sodium ions decreases below the initial level. This pharmacological "rebound" is due to a sharp increase in the activity of antinatriuretic neurohumoral links, including renin-angiotensin, which occurs in response to profuse diuresis. Due to the withdrawal syndrome when taken once a day, the drug may not have a significant effect on the daily excretion of sodium ions and blood pressure.

Furosemide is available in the form of tablets and solution for intravenous and intramuscular administration. The dosage regimen of the drug is set by the doctor individually, taking into account the indications, the nature of the course of the disease and the age of the patient. During pharmacotherapy, the dose and frequency of taking the drug is adjusted depending on the therapeutic response and the general condition of the patient. The diuretic (diuretic) effect of furosemide directly depends on its dose, while it is practically impossible to achieve a certain therapeutic "ceiling".

Among the pharmacokinetic disadvantages of furosemide, one should mention too wide a "scatter" of the bioavailability of the drug when taken orally. In different clinical situations, it can vary from 11 to 90%.

Since furosemide has a rapid and at the same time powerful antihypertensive effect, it is often used in the relief of hypertensive crises. For crises of the 1st degree, furosemide is administered orally at a dose of 40-80 mg, for crises of the 2nd degree, it is administered intravenously or intramuscularly at the same dose. At the same time, the use of furosemide in the long-term therapy of arterial hypertension seems to be irrational, because a sharp decrease in circulating blood volume and vasodilation caused by the drug cause reflex sympathetic and renin-angiotensin activation, which eliminates the antihypertensive effect. Fursemide can be used in acute heart failure. So, in acute left ventricular failure under the action of the drug, the volume of circulating blood (BCC) decreases, which reduces the work of the myocardium in pumping blood from a small circle to a large one. On the other hand, a decrease in BCC and dilation of the vessels of the small circle entails a decrease in pressure in the latter, as a result of which the release of blood plasma into the lung stops and edema increases. Furosemide is used to reduce total swelling in congestive forms of heart failure. The use of other diuretics does not allow to achieve such a pronounced effect due to a violation of their absorption in the digestive tract due to edema of the internal organs. After the elimination of massive edema, the use of furosemide is inappropriate, because. further excretion of fluid from the body activates the sympathetic renin-angiotensin-aldosterone system. The drug is also used in acute renal failure. It increases the excretion of urine, regulates the excretion of potassium ions, and in case of poisoning - "washes" the renal tubules.

Pharmacology

"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 excretion rate decreases below the initial level (the "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 1 time / 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

After oral administration, absorption is 60-70%. In severe kidney disease or chronic heart failure, the degree of absorption decreases.

Vd is 0.1 l/kg. Plasma protein binding (mainly albumin) - 95-99%. Metabolized in the liver. Excreted by the kidneys - 88%, with bile - 12%. T 1 / 2 in patients with normal kidney and liver function is 0.5-1.5 hours. With anuria, T 1 / 2 can increase up to 1.5-2.5 hours, with combined renal and hepatic insufficiency - up to 11-20 hours.

Release form

2 ml - dark glass ampoules (10) - packs of cardboard.
2 ml - dark glass ampoules (5) - contour plastic packaging (1) - cardboard packs.
2 ml - dark glass ampoules (5) - contour plastic packaging (2) - cardboard packs.

Dosage

Installed individually, depending on the indications, the clinical situation, the age of the patient. During treatment, the dosage regimen is adjusted depending on the magnitude of the diuretic response and the dynamics of the patient's condition.

When taken orally, the initial dose for adults is 20-80 mg / day, then, if necessary, the dose is gradually increased to 600 mg / day. For children, a single dose is 1-2 mg / kg.

The maximum oral dose for children is 6 mg/kg.

With intravenous (jet) or intramuscular administration, the dose for adults is 20-40 mg 1 time / day, in some cases - 2 times / day. For children, the initial daily dose for parenteral use is 1 mg / kg.

Interaction

With simultaneous use with antibiotics of the aminoglycoside group (including with gentamicin, tobramycin), it is possible to increase the nephro- and ototoxic effect.

Furosemide reduces the clearance of gentamicin and increases plasma concentrations of gentamicin, as well as tobramycin.

With simultaneous use with antibiotics of the cephalosporin group, which can cause impaired renal function, there is a risk of increased nephrotoxicity.

With simultaneous use with beta-agonists (including fenoterol, terbutaline, salbutamol) and with GCS, hypokalemia may increase.

With simultaneous use with hypoglycemic agents, insulin may reduce the effectiveness of hypoglycemic agents and insulin, tk. furosemide has the ability to increase the content of glucose in the blood plasma.

With simultaneous use with ACE inhibitors, the antihypertensive effect is enhanced. Severe arterial hypotension is possible, especially after taking the first dose of furosemide, apparently due to hypovolemia, which leads to a transient increase in the hypotensive effect of ACE inhibitors. The risk of impaired renal function increases and the development of hypokalemia is not excluded.

With simultaneous use with furosemide, the effects of non-depolarizing muscle relaxants are enhanced.

With simultaneous use with indomethacin, other NSAIDs, a decrease in the diuretic effect is possible, apparently due to inhibition of prostaglandin synthesis in the kidneys and sodium retention in the body under the influence of indomethacin, which is a nonspecific COX inhibitor; decrease in antihypertensive effect.

It is believed that furosemide interacts in a similar way with other NSAIDs.

When used simultaneously with NSAIDs, which are selective COX-2 inhibitors, this interaction is much less pronounced or practically absent.

With simultaneous use with astemizole, the risk of developing arrhythmias increases.

With simultaneous use with vancomycin, it is possible to increase oto- and nephrotoxicity.

With simultaneous use with digoxin, digitoxin, an increase in the toxicity of cardiac glycosides is possible, associated with the risk of developing hypokalemia while taking furosemide.

There are reports of the development of hyponatremia with simultaneous use with carbamazepine.

With simultaneous use with colestyramine, colestipol, the absorption and diuretic effect of furosemide decreases.

With simultaneous use with lithium carbonate, it is possible to enhance the effects of lithium due to an increase in its concentration in the blood plasma.

With simultaneous use with probenecid, the renal clearance of furosemide decreases.

With simultaneous use with sotalol, hypokalemia and the development of ventricular arrhythmia of the "pirouette" type are possible.

With simultaneous use with theophylline, a change in the concentration of theophylline in the blood plasma is possible.

With simultaneous use with phenytoin, the diuretic effect of furosemide is significantly reduced.

After the on / in the introduction of furosemide against the background of therapy with chloral hydrate, an increase in sweating, a feeling of heat, instability of blood pressure, tachycardia is possible.

With simultaneous use with cisapride, hypokalemia may increase.

It is assumed that furosemide can reduce the nephrotoxic effect of cyclosporine.

With simultaneous use with cisplatin, an increase in the ototoxic effect is possible.

Application features

Use during pregnancy and lactation

During pregnancy, the use of furosemide is possible only for a short time and only if the expected benefit of therapy for the mother outweighs the potential risk to the fetus.

Since furosemide can be excreted in breast milk, as well as suppress lactation, breastfeeding should be discontinued if necessary during lactation.

Application for violations of liver function

Application for violations of kidney function

special instructions

Use with caution in prostatic hyperplasia, SLE, hypoproteinemia (risk of developing ototoxicity), diabetes mellitus (decrease in glucose tolerance), with stenosing atherosclerosis of cerebral arteries, against the background of prolonged therapy with cardiac glycosides, in elderly patients with severe atherosclerosis, pregnancy (especially first half), lactation period.

Before starting treatment, electrolyte disturbances should be compensated. During treatment with furosemide, it is necessary to control blood pressure, electrolyte and glucose levels in the blood serum, liver and kidney function.

For the prevention of hypokalemia, it is advisable to combine furosemide with potassium-sparing diuretics. With the simultaneous use of furosemide and hypoglycemic drugs, dose adjustment of the latter may be required.

Influence on the ability to drive vehicles and control mechanisms

When using furosemide, it is impossible to exclude the possibility of a decrease in the ability to concentrate, which is important for people who drive vehicles and work with mechanisms.

Furosemide is an effective fast-acting diuretic used for excessive accumulation of fluid in the organs of the urinary system, as a diuretic for edema, etc. Let us consider in more detail the drug Furosemide - why it is prescribed, how the tablets or solution work and how effective they are.

Feature of the product

The drug is produced both in the form of tablets and in the form of a solution for injection. The rate of appearance of the first positive results of treatment with Furosemide depends on the use of one or another dosage form of the drug. So, when administered intravenously, it can quickly cause the desired effect and has a diuretic effect after 15 minutes, when using a tablet form - after half an hour. In this case, the effect persists for quite a long time, up to four hours.

For Furosemide, the indications for use are quite extensive. This medicine is prescribed for diseases such as hypertension, kidney and heart failure, nephrotic syndrome, as well as for serious disorders of the liver (for example, with cirrhosis).

Furosemide is also often chosen for cystitis. Unlike many drugs of similar action, it does not reduce glomerular filtration. This allows it to be used in renal failure. The hypotensive effect of the drug expands the scope of its application.

However, this drug may not always be prescribed. For Furosemide, contraindications may be:

The drug should be prescribed by a doctor who explains in advance how to take Furosemide correctly, how to respond to possible side effects. If such phenomena as nausea, vomiting, bouts of thirst, dizziness, diarrhea occur, you should immediately inform your doctor about this. Usually in this case, the dosage of the drug is reduced, or Furosemide is replaced by another drug. In addition to those listed, there may be side effects such as various allergic reactions, general weakness, etc.

As a rule, Furosemide for edema is prescribed at a dosage of 40 mg per day, for which the method of administration is determined - 1 tablet per day in the morning. The dosage can be doubled and divided into two doses with an interval of 6 hours (in the first half of the day). After the swelling decreases, the dosage of the drug is gradually reduced, the interval between applications increases. For children, the dosage is calculated depending on body weight, namely 1-2 mg of medication per kilogram of weight.

Furosemide for cystitis

In order to understand why Furosemide is prescribed for cystitis, you need to know what this disease is. Cystitis is an inflammatory process that occurs in the bladder, which is of a bacterial nature and primarily affects the mucous membrane of the organ. The causative agents of cystitis are the bacteria Escherichia and Pseudomonas aeruginosa, staphylococcus and Candida fungi. Once in the bladder, these microorganisms begin to multiply actively, as a result of which the order of the work of this organ is disrupted.

Cystitis, as an indication for the use of Furosemide, is considered because the inflammatory process occurring in the bladder requires the prevention of urinary stagnation, as a condition for its development. Unfortunately, most often cystitis becomes chronic due to the patient's incorrect approach to treatment. Often, the patient independently chooses medications and methods of therapy, uses traditional medicine, and determines when to stop treatment. In this case, little attention is usually paid to establishing the process of excretion of urine in sufficient volume, and this has a direct effect on suppressing the focus of inflammation in the organs of the urinary system in general and the bladder in particular.

Usually, in the process of treating cystitis, doctors recommend that patients drink as much fluid as possible, while prescribing various diuretics. Furosemide for cystitis is prescribed in this capacity. This approach provides a regular outflow of large volumes of urine, which leads to a decrease in inflammation and a decrease in signs of intoxication.

However, Furosemide for cystitis cannot be the only drug or form the basis of therapy. It must be remembered that inflammation of a bacterial nature requires the use of antibiotics or at least antiseptic herbal preparations, if we are talking about the initial stage of the disease. In the absence of a full-fledged treatment, the disease will progress, and symptoms such as:

If the symptomatic picture is replenished with the above signs, the patient will be shown hospitalization and long-term treatment. Otherwise, the patient's condition will worsen even more, and the disease will lead to serious complications.

Furosemide for edema

If Furosemide is prescribed for cystitis to stimulate the excretion of urine and increase the volume of circulating fluid, then for edema it is used to remove excess fluid from the body. In this case, the patient is usually advised, on the contrary, to reduce the amount of water consumed.

It is very important to maintain a balance in the process of water-salt metabolism. The fluid consumed and excreted must be equivalent in volume. Otherwise, excess fluid will accumulate in the body. If at the same time it begins to be deposited in tissues and cavities, a person may not notice this at first. Only external edema formed on the face, limbs, etc. become noticeable immediately.

Edema occurs due to a number of diseases and dysfunctions. For example, due to allergies, liver disease, due to the use of certain drugs. In any case, excess fluid must be removed from the body. In the absence of contraindications, furosemide can be used for edema.

In this case, it is usually prescribed in the standard dosage - 1 tablet per day (in the morning) daily, as swelling decreases, 1 time in two or three days, until the complete cessation of use.

It is noted that a person who has taken the drug once already notices a slight decrease in edema, and after a few days they, in most cases, disappear completely.

Of course, in this case, it is necessary to take other measures, primarily aimed at eliminating the causes that caused the appearance of puffiness. If the disease that provoked the formation of edema is not cured, then this symptom will return again after stopping Furosemide. Meanwhile, it is impossible to abuse this drug. It must be used according to the scheme established by the attending physician and only after the appointment has been made.

You should be aware that the uncontrolled use of diuretics, including Furosemide, can lead to very serious consequences. In addition, with the liquid excreted from the body, especially in large volumes, many useful elements are washed out, such as magnesium, calcium, potassium, sodium, etc. If the drug is prescribed by a doctor, he gives recommendations for correcting nutrition or prescribes vitamin-mineral complexes.

If, for some reason, the use of diuretics is not possible, for example, the maximum allowable duration of the course of taking Furosemide is exceeded, you can use other methods to relieve edema. For example, a light stroking massage, foot baths, and rest help a lot in this case. You can consult with a specialist who can offer additional options for eliminating this symptom.

Any changes in the patient's condition and therapy for edema should be monitored by the attending physician, since self-medication can lead to an imbalance in the body's water balance, which in itself is very dangerous.

There are many diseases that may require the use of diuretics. They are necessary to remove stagnant urine in order to eliminate edema in a variety of pathological conditions. It is important that diuretics are used, as a rule, in rather severe cases with severe swelling, acute intoxication of the body and a sharp increase in blood pressure. Furosemide is a powerful, fast-acting diuretic.

In what form is it issued

Furosemide tablets - a form for oral administration. The medicine package contains 50 tablets. The active ingredient (furosemide) in each of them contains 40 mg, in addition, there are auxiliary components. These include:

• lactose;
• potato starch;
• magnesium stearate;
• gelatin.

The white tablet has a flat-cylindrical shape. Tablets can be placed in dark glass bottles or in polymer containers.

Furosemide injection solution is a concentrate of this substance. Additional elements:

• sodium chloride;
• sodium hydroxide;
• water for injections.

The drug in this form is packaged in glass ampoules with a capacity of 2 ml of the drug.

Diuretic Furosemide belongs to the group of "loop diuretics". All of them in general, and Furosemide in particular, have a directed effect on the loop of Gengle, which is the renal tubule. It is characterized by the fact that it is directly responsible for the process of reabsorption of the liquid with all the substances dissolved in it.

Furosemide has a pronounced diuretic effect and is characterized by a fast, but short-lived effect.

Doctor's opinion:
“When taking tablets, the therapeutic effect occurs after 20-30 minutes, after intravenous administration, the onset of action is halved and is 15-20 minutes. The duration of exposure is purely individual for each individual patient and can vary from 3 to 6 hours. The peak of exposure is noted 1-2 hours after taking the pill or within 30 minutes after the administration of the drug. It is noteworthy: kidney dysfunction is more pronounced - the action of the diuretic is longer”

The action of the drug is based on a violation of the reabsorption of chloride and sodium ions in the renal tubules. The excretion of magnesium, calcium and phosphates is increased.

If the drug is used in heart failure, then the preload on the heart muscle decreases 20 minutes after ingestion.

Already after 2 hours, the tone of the veins and the volume of circulating blood and fluid filling the intercellular spaces decrease - this is how the hemodynamic effect manifests itself.

With a single daily administration of the drug, there is no particular effect on blood pressure or sodium excretion.

The drug is characterized by rapid absorption and bioavailability (60-70% when using tablets). Communication with plasma proteins - 98%, and it is much lower in renal failure.

The breakdown occurs in the liver, and its products enter the renal tubules.

Excretion is carried out for the most part by the kidneys (60-70%), the rest is with faeces. If the drug was administered intravenously, then 88% is excreted by the kidneys, the rest with feces.

Important!

The tool has a high ability to overcome the placental barrier and be absorbed into breast milk.

In elderly patients, the diuretic effect is much lower.

The drug should be taken with caution, since in addition to unnecessary stagnant urine, sodium and chlorine salts are excreted.

Furosemide Sopharma- this is the same drug produced by Sopharma. Many believe that the drugs of this company are of better quality, but the indications and medicinal effects of these drugs are absolutely identical.

What is prescribed for: indications for use

The use of tablets is advisable in the following cases:

• Edema of a very different nature, including with renal and heart failure.

Important!

Furosemide is rarely prescribed for cystitis, and this is due, not least, to the negative effects of this drug.

For the treatment of this disease, there are many special drugs. The drug, rather, is used for cystitis as part of self-medication and it is fraught with the development of additional diseases. It should be remembered that even a course of treatment with Furosemide will not rid the bladder of pathogenic microflora, because cystitis is inflammation.

Instructions for use

The drug in tablets begins to be taken from 20 mg per day of a person. If the desired effect is not obtained, then the dose is increased, but the daily maximum is 1.5 g. The tablet is swallowed whole, without chewing, with a small amount of water. The dosage of the drug, as well as the duration of treatment, is selected individually, it depends directly on age, body weight, the severity of the edema itself and the existing diseases. Between doses of tablets should pass at least 6 hours.

Furosemide and alcohol are incompatible. This combination greatly enhances the side effects.

Furosemide instructions for use: a combination of the drug with antihypertensive drugs is allowed - the dose is 20-120 mg per day. Constant monitoring of blood pressure is very important in order to prevent its sharp and significant drop.

If the cardiac, pulmonary or hepatic origin of edema is established, then it is prescribed: in moderate states, 0.5-1 tablet per day, in severe cases, 2-3 tablets per day, sometimes even 4.

Use of this product in children: The recommended dosage is 1-2mg/kg body weight.

Elderly patients require special attention when choosing a dose, it is necessarily minimal.

Furosemide ampoules with solution for injection are used for intravenous infusions. The introduction must be slow, about 1-2 minutes. Only paramedics can give these injections. If the daily dosage exceeds 80 ml, then droppers with this drug may be indicated. As soon as possible, the patient should be switched to tablets.

Overdose and side effects

Adverse reactions occur, as a rule, with inaccurate dosage. Such manifestations include:

• a jump in blood pressure to the lower side, thrombosis, the occurrence of acute vascular insufficiency;
• muscle weakness and cramps, drowsiness and general lethargy, dizziness;
• sensation of tinnitus;
• thirst with dry mouth, abdominal pain, nausea and vomiting, reactive pancreatitis;
• a sharp decrease in urine output, blood impurities in it, a decrease in libido and even impotence, proliferation of prostate cells;
• dermatitis, urticaria, in severe cases - angioedema, anaphylactic shock;
• a decrease in the level of leukocytes and platelets in the blood, an increase in the level of eosinophils, anemia;
• decrease in the level of potassium, calcium and magnesium ions.

If any of the above effects occur, then either the complete abolition of the drug or a decrease in its dosage follows. An extensive list of possible side effects indicates how actively this substance affects existing human organs and systems. For this reason, it is important to exclude the self-administration of Furosemide, this can cause conditions that pose a direct threat to the life of the patient.

With an incorrect or self-administered dosage, cases of drug overdose may occur. Its features include:

• violation of breathing and functioning of the cardiovascular system;
• coma;
• paralysis;
• thromboembolism;
• drowsiness;
• arrhythmias and ventricular fibrillation;
• collapse.

How it interacts with other medicines

Interaction features:

1. With Phenobarbital, the therapeutic effect of the diuretic is markedly reduced.
2. Furosemide provokes complications from taking antibiotics.
3. Medicines with aminoglycosides: the excretion of the latter is greatly slowed down.
4. Furosemide reduces the therapeutic effect of hypoglycemic agents.
5. When taken in parallel with glucocorticosteroids, the risk of hypokalemia increases.
6. Antihypertensive drugs together with a diuretic provoke a sharp drop in blood pressure.
7. There is a risk of acute renal failure with ACE inhibitors.
8. With the introduction of a radiopaque substance, kidney dysfunction may be detected.

1. This diuretic prevents the normal excretion of uric acid from the body.
2. For patients with diabetes, regular monitoring of glucose in both blood and urine is important.
3. With lactose intolerance, the medication can not be used.
4. It is important to stop the drug in patients who have problems with urine outflow.
5. For those who are prescribed high doses, it is recommended not to limit the intake of table salt and to use diets rich in potassium.

During pregnancy

The drug has a high ability to penetrate the placenta, during pregnancy, you must either completely abandon the use of this diuretic, or use it only in the most extreme cases. It is contraindicated to use the medication for physiological edema during childbearing. Doctors do not recommend the use of this diuretic during this period, because there are many much safer diuretics, even if their cost is much higher. In emergency cases, intravenous administration is considered the safest, because then the drug is more quickly excreted from the body and the effect on the fetus will be minimized.

The same applies to the period of breastfeeding: if there is an urgent need for treatment, then feeding should be suspended until the end of the course of treatment.

With cystitis

Cystitis is an inflammatory disease, therefore, anti-inflammatory drugs are prescribed first of all. Treatment with Furosemide is advisable if there is a need to remove excess fluid. With a not too acute course of cystitis, the medication is able to remove pathogenic microflora from the body, but if the disease has passed into an acute stage, such treatment will not give the expected result.

Analogues and price

The main analogue is the diuretic Lasix, Bufenox, Britomar, Diuver and can also be distinguished.

Furosemide is a fairly cheap remedy, its price fluctuates between 20-40 rubles per pack. The medication is dispensed by prescription from the attending physician.
