VINPOCETINE

General characteristics. Structure:

One tablet contains 5 mg of a Vinpocetine as active agent and excipients (лудипресс, potato starch, magnesium stearate).

Description of the Tablet of color, white or white with a yellowish shade, ploskotsilindrichesky form.

Pharmacological properties:

Pharmacodynamics. Possesses vasodilating, anti-hypoxemic and anti-aggregation action. Inhibits phosphodiesterase and increases the content of cyclic adenosinemonophosphate in cells that in turn, leads to decrease in content of calcium in cytoplasm of smooth muscle cells and to relaxation of myofibrils. Combines vascular and metabolic actions. Expands brain vessels, strengthens a blood stream, it is preferential in ischemic areas, improves supply of a brain with oxygen. Promotes utilization of glucose and increases the level of catecholamines in the central nervous system, stimulates metabolism of a noradrepalin and serotonin in brain tissues. Reduces aggregation of thrombocytes, viscosity of blood, promotes increase in deformability of erythrocytes and normalization of venous outflow against the background of decrease in resistance of brain vessels. System arterial pressure slightly goes down. It is effective in the acute period of a stroke: accelerates regress of all-brain and focal neurologic symptomatology, improves memory, attention, intellectual productivity. Sensitivity of brain vessels to the running-down action of a Vinpocetine increases in advanced and senile age that is caused by a sensitization of system of adenylatecyclase - cyclic adenosinemonophosphate when aging.

Pharmacokinetics. Bioavailability about 60% is quickly soaked up from digestive tract. The maximum concentration in a blood plasma is reached in 1 hour. Easily diffuses through gistogematichesky barriers (including through a blood-brain barrier) and gets into fabrics. Elimination half-life: about 5 hours.

Indications to use:

Acute (after the termination of a course of parenteral administration of a Vinpocetine, and also in cases when parenteral administration is not shown or it is impossible) and chronic forms of insufficiency of cerebral circulation (including acute and residual stages of a stroke, the tranzitorny ischemic attacks, encephalopathies, multiinfarctive dementia). Vascular diseases of a retina and/or a choroid of an eye (owing to arteriosclerosis, a vasomotor spasm, thrombosis); the degenerative changes of a macula lutea caused by atherosclerosis or a vasomotor spasm; secondary glaucoma (owing to obturation of vessels). Age vascular or toxic (medicamentous) hearing disorder, Menyer's disease, dizzinesses of a labyrinth origin. Vegetative manifestations of a menopausal syndrome.

Route of administration and doses:

Inside on 5-10 mg 3 times a day within 2 months. Before drug withdrawal it is necessary to reduce a dosage gradually. Repeated courses 2-3 times a year are possible.

Side effects:

Lowering of arterial pressure, tachycardia, premature ventricular contraction, delay of intra ventricular conductivity.

Contraindications:

Hypersensitivity, the expressed disturbances of a heart rhythm, coronary heart disease (heavy current), acute stage of a hemorrhagic stroke, pregnancy, the lactation period.

Overdose:

At intoxication the gastric lavage, reception of absorbent carbon and a symptomatic treatment are recommended. Interaction with other medicines: Increases risk of hemorrhagic complications against the background of a geparinoterapiya.
