Clinical-Pharmacological Group

A drug that improves cerebral circulation and metabolism

Pharmacotherapeutic Group

Cerebrovasodilating agent

Pharmacological Action

A drug that improves cerebral circulation and brain metabolism. It inhibits the activity of phosphodiesterase, which promotes the accumulation of cAMP in tissues.

It has a vasodilating effect primarily on the cerebral vessels, which is due to a direct myotropic antispasmodic action. Systemic blood pressure decreases insignificantly.

It improves blood supply and microcirculation in brain tissues, reduces platelet aggregation, and promotes the normalization of the rheological properties of blood.

It improves the tolerance of brain cells to hypoxia by promoting oxygen transport to tissues due to a decrease in the affinity of erythrocytes for it, and enhances the uptake and metabolism of glucose. It increases the content of catecholamines in brain tissues.

Pharmacokinetics

When taken orally, it is rapidly absorbed from the gastrointestinal tract. C_max in blood plasma is reached in approximately 1 hour.

With parenteral administration, V_d is 5.3 l/kg. T_1/2 is about 5 hours.

Indications

Acute and chronic cerebral circulation insufficiency. Dyscirculatory encephalopathy accompanied by memory impairment, dizziness, headache. Post-traumatic encephalopathy.

Vascular diseases of the retina and choroid. Hearing impairment of vascular or toxic origin, Meniere’s disease, dizziness of labyrinthine origin. Vegetative-vascular dystonia in climacteric syndrome.

ICD codes

Dosage Regimen

Administer orally with a full glass of water after meals to minimize gastrointestinal discomfort.

The standard adult oral dosage is 5 mg to 10 mg taken three times daily.

For parenteral administration, reserve for acute conditions; administer a single dose of 20 mg intravenously.

With good tolerance, increase the parenteral dose gradually over three to four days to a target of 1 mg per kg of body weight.

The typical duration of parenteral treatment is 10 to 14 days.

Following the acute phase, transition from injectable to oral therapy for long-term management.

Do not administer parenterally in the acute phase of a hemorrhagic stroke; delay use until 5-7 days post-event.

Do not use in children or adolescents under 18 years of age.

Adjustment for hepatic or renal impairment is not typically required; use the standard dose.

Adverse Reactions

From the hematopoietic system rarely – leukopenia, thrombocytopenia, decrease/increase in the number of eosinophils; very rarely – anemia, agglutination of erythrocytes, erythrocytopenia.

From the immune system very rarely – hypersensitivity reactions.

From metabolism infrequently – hypercholesterolemia; rarely – decreased appetite, anorexia, diabetes mellitus, hypertriglyceridemia; very rarely – increased body weight.

Mental disorders rarely – insomnia, sleep disorder, anxiety; very rarely – euphoria, depression.

From the nervous system infrequently – headache; rarely – dizziness, dysgeusia, stupor, hemiparesis, drowsiness, amnesia; very rarely – tremor, spasms.

From the organ of vision rarely – edema of the optic disc; very rarely – conjunctival hyperemia.

From the organ of hearing and labyrinthine disorders infrequently – vertigo; rarely – hyperacusis, hypoacusis, tinnitus.

From the cardiovascular system infrequently – decreased BP; rarely – myocardial ischemia/infarction, angina pectoris, bradycardia, tachycardia, extrasystole, palpitation sensation, increased BP, “hot flashes”, thrombophlebitis; rarely – ST segment depression on ECG; very rarely – arrhythmia, atrial fibrillation, BP lability.

From the digestive system infrequently – abdominal discomfort, dry mouth, nausea; rarely – epigastric pain, constipation, diarrhea, dyspepsia, vomiting, increased activity of liver enzymes; very rarely – dysphagia, stomatitis.

From the skin and subcutaneous tissues rarely – erythema, hyperhidrosis, pruritus, urticaria, rash; very rarely – dermatitis.

Other rarely – asthenia, malaise, feeling of heat; very rarely – feeling of chest discomfort, hypothermia, decrease in prothrombin time values.

Contraindications

Hypersensitivity to vinpocetine; pregnancy, breastfeeding period; children and adolescents under 18 years of age; for parenteral use – acute phase of hemorrhagic stroke, severe coronary artery disease, severe forms of arrhythmia.

With caution

For parenteral use: increased intracranial pressure, use of antiarrhythmic drugs, long QT syndrome.

Use in Pregnancy and Lactation

Contraindicated for use during pregnancy.

Use during breastfeeding is contraindicated.

Use in Hepatic Impairment

In case of liver diseases, use at the usual dose.

Use in Renal Impairment

In case of kidney diseases, use at the usual dose.

Pediatric Use

Use in children and adolescents under 18 years of age is contraindicated.

Geriatric Use

Used in elderly patients as indicated.

Special Precautions

Use orally with caution in arrhythmia, angina pectoris, with unstable blood pressure and reduced vascular tone. Parenterally, as a rule, it is used in acute cases until the clinical picture improves, then they switch to oral administration. For chronic diseases, Vinpocetine is taken orally. In hemorrhagic cerebral stroke, parenteral administration of vinpocetine is allowed only after the acute phenomena have subsided (usually 5-7 days).

Drug Interactions

When used concomitantly with warfarin, a slight decrease in the anticoagulant effect of warfarin has been reported.

Concomitant use of vinpocetine and alpha-methyldopa sometimes caused some enhancement of the hypotensive effect, therefore, with such treatment, regular blood pressure monitoring is required.

Despite the lack of data confirming the possibility of interaction, caution is recommended when co-administering with drugs acting on the central nervous system and with drugs of antiarrhythmic and anticoagulant action.

Storage Conditions

Store at 2°C (36°F) to 25°C (77°F). Keep in original packaging, protected from light. Keep out of reach of children.
