Pharmacological properties
Pharmacodynamics
Ethylmethylhydroxypyridine succinate belongs to the class of 3-hydroxypyridines, is an inhibitor of free radical processes, a membrane protector. It also has an antihypoxic effect, increases the body’s resistance to stress.
The mechanism of action of ethylmethylhydroxypyridine succinate is due to its antioxidant and membrane-protective effect. The drug inhibits lipid peroxidation, increases the activity of superoxide oxidase, increases the lipid-protein ratio, improves the structure and function of the cell membrane.
Ethylmethylhydroxypyridine succinate simulates the activity of membrane-bound enzymes (calcium-independent phosphodiesterase, adenylate cyclase, acetylcholinesterase) and receptor complexes (benzodiazepine, GABA, and acetylcholine), which enhances their ability to bind to ligands, helps preserve the structural and functional organization of biomembranes, transport neurotransmitters, and improve synaptic transmission. Ethylmethylhydroxypyridine succinate increases the level of dopamine in the brain. Causes an increase in compensatory activation of aerobic glycolysis and a decrease in the degree of inhibition of oxidative processes in the Krebs cycle under hypoxic conditions with an increase in the content of adenosine triphosphoric acid (ATP) and creatine phosphate, activation of energy-synthesizing functions of mitochondria.
Increases the body’s resistance to the effects of various damaging factors in pathological conditions (hypoxia and ischemia, impaired cerebral circulation, intoxication with ethanol and antipsychotic drugs).
In conditions of critical reduction of coronary blood flow, it helps to preserve the structural and functional organization of cardiomyocyte membranes, stimulates the activity of membrane enzymes-phosphodiesterase, adenylate cyclase, and acetylcholinesterase. Supports the activation of acetylcholinesterase that develops in acute ischemia. It supports the activation of aerobic glycolysis that develops in acute ischemia and promotes the restoration of mitochondrial redox processes in hypoxia, increases the synthesis of ATP and creatine phosphate. Ensures the integrity of morphological structures and physiological functions of the ischemic myocardium. Improves the clinical course of myocardial infarction, increases the effectiveness of therapy, reduces the incidence of arrhythmia and disorders of intracardiac conduction.
Normalizes metabolic processes in the ischemic myocardium, increases the antianginal activity of nitrates, improves the rheological properties of blood, reduces the consequences of reperfusion syndrome in acute coronary insufficiency.
Promotes the preservation of retinal ganglion cells and optic nerve fibers in progressive neuropathy caused by chronic ischemia and hypoxia. Improves the functional activity of the retina and optic nerve, increasing visual acuity.
Reduces enzymatic toxemia and endogenous intoxication in acute pancreatitis.
Improves metabolism and blood supply to the brain, microcirculation and rheological properties of blood, reduces platelet aggregation. Stabilizes the membranes of blood cells (red blood cells and platelets), reducing the likelihood of developing hemolysis. It has a hypolipidemic effect by reducing the content of total cholesterol and low-density lipoproteins.
Pharmacokinetics
Suction
With a single and course use, the maximum concentration (Cmax) in blood plasma is reached after 0.58 hours. When administered at a dose of 400-500 mg (Cmax) in blood plasma-3.5-4 mcg / ml.
Distribution
It is rapidly distributed in organs and tissues. The average retention time of ethylmethylhydroxypyridine succinate in the body is 0.7-1.3 hours.
Metabolism
It is metabolized in the liver by glucuronidation. 5 metabolites were identified: 3-oxypyridine phosphate-is formed in the liver and breaks down into phosphoric acid and 3-oxypyridine with the participation of alkaline phosphatase; the 2nd metabolite is pharmacologically active, is formed in large quantities and is detected in the urine 1-2 days after use; the 3rd – is excreted in large quantities in the urine; the 4th and 5th-glucuronconjugates. Deduction
It is removed from the blood plasma quickly and is practically undetectable after 4 hours in it. It is rapidly excreted in the urine mainly in the form of metabolites (50% in 12 hours) and in a small amount – in unchanged form (0.3% in 12 hours). Urinary excretion rates of unchanged ethylmethylhydroxypyridine succinate and its metabolites are individually variable.

How to take, course of use and dosage
Intramuscularly or intravenously (jet or drip). With the infusion method of use, the drug should be diluted in 0.9% sodium chloride solution.
Doses are selected individually.
Jet is administered slowly for 5-7 minutes, drip at a rate of 40-60 drops per minute. The maximum daily dose should not exceed 1200 mg.
