Pharmacological properties

Pharmacodynamics

The active component of Metostabil is ethylmethylhydroxypyridine (2-ethyl-6-methyl-3-hydroxypyridine) succinate, belonging to the class of 3-hydroxypyridines, is a membrane protector, inhibits the course of free radical processes, has an antihypoxic effect, and enhances the body's stress resistance. The mechanism of action of 2-ethyl-6-methyl-3-hydroxypyridine succinate is determined by its antioxidant and membrane-protective effects. The drug stimulates the growth of superoxide oxidase activity, inhibits lipid peroxidation, increases the ratio of lipids and proteins, improves the structure and function of the plasma membrane.

The main pharmacological properties of ethylmethylhydroxypyridine succinate:

• modulation of the activity of membrane-bound enzymes (adenylate cyclase, acetylcholinesterase, calcium-independent phosphodiesterase) and receptor complexes [benzodiazepine, acetylcholine, GABA (gamma-aminobutyric acid)], which leads to an increase in their ability to bind to ligands-functional, allowing to maintain the biomembrane transport neurotransmitters and improved synaptic transmission; increased dopamine content in the brain;
• enhancement of compensatory activation of aerobic glycolysis under conditions of hypoxia and a decrease in the degree of inhibition of oxidative processes in the Krebs cycle with an increase in the level of adenosine triphosphate and creatine phosphoric acids, activation of energy-synthesizing functions of mitochondria;
• an increase in the body's resistance to various damaging factors in such pathological conditions as cerebrovascular accident, hypoxia and ischemia, intoxication with ethanol and neuroleptics;
• preservation of the structural and functional organization of cardiomyocyte membranes in conditions of a critical decrease in coronary blood flow, stimulation of the activity of such membrane enzymes as adenylate cyclase, acetylcholinesterase, phosphodiesterase;
• support for the activation of aerobic glycolysis that develops in acute ischemia and assistance in the restoration of mitochondrial redox processes under hypoxic conditions, increased synthesis of adenosine triphosphate and creatine phosphate; ensuring the integrity of physiological functions and morphological structures of the ischemic myocardium;
• improving the picture of the clinical course of myocardial infarction and the effectiveness of thrombolytic (fibrinolytic) therapy, reducing the incidence of arrhythmias and cardiac conduction disorders;
• normalization of metabolic processes in the ischemic myocardium, an increase in the antianginal activity of nitrates, an improvement in the rheological properties of blood, a decrease in the consequences of reperfusion syndrome in patients with acute coronary insufficiency;
• decrease in patients with acute pancreatitis of the severity of enzymatic toxemia and endogenous intoxication;
• increased metabolism and blood supply to the brain, improved microcirculation and rheological properties of blood, reduced platelet aggregation, stabilized membranes of blood cell elements (erythrocytes and platelets), reduced risk of hemolysis;
• a decrease in the concentration of total cholesterol and low density lipoproteins due to the hypolipidemic effect;
• preservation of retinal ganglion cells and optic nerve fibers in patients with progressive neuropathy developing as a result of chronic ischemia and hypoxia; improving the functional activity of the retina and optic nerve, increasing visual acuity (solution for intravenous and intramuscular administration).

Pharmacokinetics

• absorption and distribution: as a result of parenteral administration of 400–500 mg of Metostabil, the maximum concentration of its active substance (C _max) in blood plasma reaches 3.5–4 μg / ml. With both single and course use, the time to reach the maximum concentration (T _Cmax) in the blood plasma is 0.58 h. After oral administration, the half-absorption period is 0.08–1 h, C _max reaches a level of 50–100 ng / ml, and the T _Cmax value varies in the range of 0.46–0.5 hours. The substance is rapidly distributed in tissues and organs. The average time at which 2-ethyl-6-methyl-3-hydroxypyridine succinate is determined in the body for parenteral and oral administration is 0.7-1.3 and 4.9-5.2 hours, respectively;
• metabolism: biotransformation of 2-ethyl-6-methyl-3-hydroxypyridine succinate occurs in the liver through glucuronidation. As a result, 5 identifiable metabolites are formed: 1st - 3-hydroxypyridine phosphate (formed in the liver and with the participation of alkaline phosphatase decomposes into 3-hydroxypyridine and phosphoric acid); 2nd - is pharmacologically active, is formed in large quantities and is determined in urine 1–2 days after the use of Metostabil; 3rd - eliminated in large quantities in the urine; 4th and 5th are glucuron conjugates;
• Elimination: 4 hours after parenteral administration of 2-ethyl-6-methyl-3-hydroxypyridine, succinate is practically not detected in blood plasma. When ingested, it is most intensively excreted during the first 4 hours, T _1/2 (half-life) is from 4.7 to 5 hours. The substance is rapidly eliminated in the urine, mainly in the form of metabolites - up to 50% within 12 hours, an insignificant amount is excreted in the form of an unchanged substance - 0.3% within 12 hours. The quantitative characteristics of the elimination of unchanged drug and its metabolites through the urinary system are characterized by significant individual variability.

• acute intoxication with neuroleptics: 200–500 mg intravenously 1 time per day; course - 7-14 days;
• acute myocardial infarction: for the first 5 days, in order to achieve maximum clinical effect, the solution is recommended to be administered slowly intravenously (to avoid side reactions) by drip infusion, lasting 30-60 minutes, it should be diluted in 100-150 ml of 0.9% sodium chloride solution or 5% dextrose solution (if necessary, Metostabil can also be injected slowly in a jet for at least 5 minutes); the next 9 days, the solution is administered intramuscularly. Infusion and injections are carried out 3 times a day at regular intervals (1 time in 8 hours); the therapeutic dose is determined from the calculation: daily - 6-9 mg / kg of the patient's body weight; single dose - 2-3 mg / kg, while the maximum single dose should not exceed 250 mg, daily dose - 800 mg; course - 14 days (against the background of standard therapy for myocardial infarction);
• glaucoma: 100–300 mg intramuscularly 1 time per day; course - 14 days.

The maximum daily dose for parenteral administration of Metostabil is 1200 mg.

Film-coated tablets

Metostabil tablets are intended for oral administration.

Recommended dosage regimen: 3 times a day, 1-2 tablets (125-250 mg). The course of therapy is from 2 to 6 weeks.

For relief of alcohol withdrawal at the beginning of treatment, take 1-2 times a day, 1-2 tablets (125-250 mg), the dose is gradually increased until a stable therapeutic effect is obtained. The course of therapy is 5-7 days. The treatment should be completed by reducing the dose gradually over 2-3 days.

The maximum daily dose for oral administration of Metostabil is 800 mg.

The duration of the course of treatment for patients with coronary artery disease should be at least 1.5–2 months.

Side effects

With intramuscular or intravenous administration of Metostabil solution, the following negative side reactions from organs and systems are possible:

• digestive system: dryness of the oral mucosa / metallic taste in the mouth, nausea, diarrhea, flatulence;
• nervous system: violation of falling asleep, drowsiness;
• respiratory system: discomfort in the chest, sore throat, feeling of lack of air (it is short-term, most often associated with a too high rate of solution administration);
• cardiovascular system: short-term increase in blood pressure;
• others: hypersensitivity reactions, unpleasant odor, feeling of spreading heat throughout the body.

As a result of taking Metostabil in the form of tablets, dryness of the oral mucosa and / or diarrhea may develop on the part of the digestive system, as well as side effects in the form of hypersensitivity reactions and / or drowsiness.

Overdose

Due to the low toxicity of ethylmethylhydroxypyridine succinate, an overdose of Metostabil is unlikely. Possible reactions in case of accidental overdose are drowsiness and sedation. Intravenous administration of high doses of the drug can cause an increase in blood pressure.

As a rule, the symptoms of an overdose disappear on their own within 1 day and do not require additional therapeutic measures. In case of an excessive increase in blood pressure, it is recommended to use antihypertensive drugs under the control of the patient's condition.

For severe intoxication, accompanied by insomnia, diazepam - 5 mg, nitrazepam - 10 mg, or oxazepam - 10 mg are prescribed.
