Methylene blue (lat. Methylenum coeruleum) are green crystals of a dark shade with a bronze luster. It was first obtained by Heinrich Cureau in 1876. Methylene blue powder has disinfecting and redox effects. Due to the fact that it forms compounds with bacterial proteins that are considered insoluble, microorganisms die.

Methylene blue

It is used as an antidote for severe poisoning, in surgery, treatment of purulent lesions, for the treatment of ENT diseases (tonsillitis, pharyngitis) in the textile industry, as a dye for materials, in analytical chemistry, for recognition chemical elements(cobalt, tin, magnesium, mercury, gum, calcium, etc.), in veterinary medicine and as a pigment for stationery pencils. Other names:

• Methylthonium chloride.
• Methylene blue.
• Methylene blue.

The powder of the drug is practically insoluble in alcohol, as well as in water, in proportions of 1:30. The solution in water is blue. Similar drugs:

• Diamond green.

• For cystitis and urethritis, use an aqueous solution of 0.002% in a ratio (1:5000). They should wash their genitals.
• For poisoning with carbon monoxide by various cyanides and hydrogen sulfide, make an aqueous solution of 1% and administer intravenously, in an amount of 50–100 ml; for poisoning with methemoglobin-forming poisons and aniline, methylene blue is used in smaller doses, this is 0.1–0.15 ml/kg. , the solution is also 1%. For carbon monoxide poisoning, use with activated carbon.

The dosage rate for an adult, when taken orally, is 0.1 g. 3-4 times a day, and for children the norm varies depending on age, it is from 0.005 to 0.01 g. 3–4 times a day.

In nephrology, it is used for the treatment of urethritis, cystitis and for diagnostic purposes, after ingestion, a solution of methylene blue gives the urine a bluish tint.

Pharmacodynamics

The active component in the drug is methylthioninium chloride, which exhibits a disinfectant, analgesic effect, participates in oxidation and reduction processes, and serves as a transporter of hydrogen molecules.

Main characteristics medicinal substance– the ability to create slightly soluble complex compounds with mucopolysaccharides and the protein part of cells pathogenic microflora. This destroys microorganisms. The external use of methylene powder prevents it from entering the circulatory system.

Issued as:

• Powdered methylene 10 g.
• 1% alcohol solution (10 and 15 ml each).

Instructions for use of methylene blue

Blue, as a powder, is an organic thiazine dye, in appearance - dark greenish crystals with a bronze tint. They are slightly soluble in water and ethyl alcohol.

Chloroform and diethyl ether They are also not suitable as solvents.

1% alcoholic methylene is applied to damaged, previously cleansed skin and healthy areas around the site of damage.

A 0.02% aqueous solution (the powder is diluted in water, ratio 1:5000) is used for rinsing for cystitis and urethritis.

0.1 g of methylene blue is taken orally 3-4 times a day. Depending on the age of children, the dosage is calculated based on 0.005-0.01 g for each year of life.

1st aqueous or 1% glucose solutions prepared with 25th glucose are administered intravenously for poisoning with nitrites, anilines, hydrocyanic acid, carbon monoxide and other substances that form methemoglobin nuclei. Medical blue is administered at the rate of 0.1-0.15 ml per kilogram of a person’s weight.

What is methylene blue? This is an aniline dye and is used not only in medicine. But as an antidote, the function of blue in toxicology and hematology is to restore methemoglobin to hemoglobin. Overdose leads to reverse process– hemoglobin is oxidized to methemoglobin, a state when oxygen cannot enter tissues and organs with the blood, which inhibits metabolic processes in them.

Side effects

Superficially applied bluing can provoke a local allergic reaction, especially in large areas of damage.

A drug administered rapidly intravenously or its overdose in some cases causes:

• vomiting, nausea, lack of appetite, pain in the epigastric region;

However, sometimes pathogenic microbes come to visit and begin to adversely affect the functioning of cells. An effective remedy antiseptics are used to combat these pests.

A few centuries ago, the concept of disinfection did not intersect with medicine in any way, until the Austrian Ignaz Semmelweis discovered the connection between with dirty hands and increasing mortality rates. With his “clean” hand, the Scot Joseph Lister invented the first antiseptic in the 19th century.

These disinfectants are actively used to heal wounds and to eliminate bacilli and fungal infections.

There are several groups of antiseptics.

Many of them have flaws that appear when used externally, such as chlorine, Strong smell which irritates the mucous membranes. Methylene blue, on the contrary, does not have negative impact on mucous membranes.
