Pharmacological Action

An inhibitor of free radical processes – a membrane protector, also possessing antihypoxic, stress-protective, nootropic, antiepileptic, and anxiolytic effects. Belongs to the class of 3-oxypyridines.

The mechanism of action is due to its antioxidant and membrane-protective properties. It suppresses lipid peroxidation, increases the activity of superoxide dismutase, increases the lipid-protein ratio, and improves the structure and function of cell membranes. It modulates the activity of membrane-bound enzymes (Ca²⁺-independent PDE, adenylate cyclase, acetylcholinesterase), receptor complexes (benzodiazepine, GABA, acetylcholine), which promotes their binding to ligands, preservation of the structural and functional organization of biomembranes, neurotransmitter transport, and improvement of synaptic transmission. It increases the concentration of dopamine in the brain.

It enhances the compensatory activation of aerobic glycolysis and reduces the degree of inhibition of oxidative processes in the Krebs cycle under hypoxic conditions with an increase in ATP and creatine phosphate, activating the energy-synthesizing function of mitochondria.

It increases the body’s resistance to the effects of various damaging factors in pathological conditions (shock, hypoxia and ischemia, cerebrovascular disorders, ethanol intoxication, and antipsychotic drugs).

It improves metabolism and blood supply to the brain, microcirculation and rheological properties of blood, and reduces platelet aggregation. It stabilizes the membranes of blood cells (erythrocytes and platelets), reducing the likelihood of hemolysis.

It has a hypolipidemic effect, reducing the content of total cholesterol and LDL.

It improves the functional state of the ischemic myocardium in myocardial infarction, the contractile function of the heart, and also reduces the manifestations of systolic and diastolic dysfunction of the left ventricle.

Under conditions of a critical decrease in coronary blood flow, it helps to preserve the structural and functional organization of cardiomyocyte membranes, stimulates the activity of membrane enzymes – PDE, adenylate cyclase, acetylcholinesterase. It maintains the activation of aerobic glycolysis developing during acute ischemia and promotes the restoration of mitochondrial redox processes under hypoxic conditions, increasing the synthesis of ATP and creatine phosphate. It ensures the integrity of the morphological structures and physiological functions of the ischemic myocardium.

It improves the clinical course of myocardial infarction, increases the effectiveness of the therapy, accelerates the recovery of the functional activity of the left ventricular myocardium, and reduces the frequency of arrhythmias and intracardiac conduction disturbances. It normalizes metabolic processes in the ischemic myocardium, reduces the necrosis zone, restores and/or improves the electrical activity and contractility of the myocardium, and also increases coronary blood flow in the ischemia zone, enhances the antianginal activity of nitro drugs, improves the rheological properties of blood, and reduces the consequences of reperfusion syndrome in acute coronary insufficiency.

It reduces enzymatic toxemia and endogenous intoxication in acute pancreatitis.

Pharmacokinetics

It is rapidly absorbed when taken orally (half-absorption period – 0.08-1 h). T_max after intramuscular administration – 0.3-0.58 h, after oral administration – 0.46-0.5 h. C_max after intramuscular administration at a dose of 400-500 mg – 2.5-4 µg/ml, after oral administration – 50-100 ng/ml.

It is rapidly distributed in organs and tissues. The mean residence time of the drug in the body after intramuscular administration is 0.7-1.3 h, after oral administration – 4.9-5.2 h.

It is metabolized in the liver by glucuronidation. Five metabolites have been identified: 3-oxypyridine phosphate – formed in the liver and, with the participation of alkaline phosphatase, breaks down into phosphoric acid and 3-oxypyridine; the 2nd metabolite is pharmacologically active, formed in large quantities and detected in urine 1-2 days after administration; the 3rd is excreted in large quantities in the urine; the 4th and 5th are glucuronoconjugates.

T_1/2 after oral administration – 4.7-5 h. It is rapidly excreted in the urine mainly as metabolites (50% within 12 h) and in small amounts – unchanged (0.3% within 12 h). It is most intensively excreted within the first 4 hours after taking the drug. The indicators of excretion of the unchanged drug and metabolites in the urine have significant individual variability.

Indications

Anxiety disorders in neurotic and neurosis-like conditions; vegetative-vascular dystonia; dyscirculatory encephalopathy; mild cognitive disorders of atherosclerotic origin.

Acute cerebrovascular accidents (as part of combination therapy).

Withdrawal syndrome in alcoholism with a predominance of neurosis-like and vegetative-vascular disorders; acute intoxication with antipsychotic drugs.

Acute purulent-inflammatory processes in the abdominal cavity (including acute necrotizing pancreatitis, peritonitis (as part of complex therapy));

Acute myocardial infarction from the first days (parenterally); Coronary artery disease; complex therapy of ischemic stroke (orally) – as part of complex therapy.

Dosage Regimen

Determine the dose, route of administration, and treatment duration individually based on the specific indication and clinical presentation.

For oral administration, administer a total daily dose of 250-500 mg. Divide this dose into two or three separate administrations throughout the day. Do not exceed the maximum daily dose of 600-800 mg.

For parenteral use, administer via intramuscular or intravenous routes. The intravenous route may be used for bolus injection or infusion. A single administered dose ranges from 50 mg to 400 mg. The maximum daily dose for parenteral administration is 1200 mg.

Adjust the injection rate for intravenous administration carefully to minimize adverse effects. For bolus injection, administer the solution slowly over several minutes. For infusion, dilute the required dose in a suitable volume of 0.9% sodium chloride solution or 5% dextrose solution.

In cases of acute cerebrovascular accident, initiate therapy with parenteral administration. Transition to oral administration for continuation of therapy as clinically indicated.

For the management of alcohol withdrawal syndrome, use a dosing schedule that typically spans 5 to 7 days. Titrate the dose based on the severity of autonomic and neurosis-like symptoms.

In the context of acute myocardial infarction, begin parenteral administration from the first day. Integrate this drug into the standard comprehensive treatment regimen for this condition.

The duration of the entire therapeutic course is variable. It depends on the disease being treated and the observed clinical response. A typical course of treatment may last from two to six weeks. Repeat courses are possible following a physician’s assessment and decision.

Adverse Reactions

When taken orally nausea, dry mouth, diarrhea, drowsiness, allergic reactions.

With parenteral administration (especially intravenous bolus) dryness, “metallic” taste in the mouth, sensations of “spreading warmth” throughout the body, unpleasant odor, sore throat and discomfort in the chest, feeling of shortness of breath (usually associated with an excessively high rate of administration and are short-term in nature); with prolonged use – nausea, flatulence; sleep disorders (drowsiness or difficulty falling asleep).

Contraindications

Hypersensitivity; acute hepatic and/or renal failure; pregnancy; lactation period; childhood.

Use in Pregnancy and Lactation
