DESCRIPTION OF ACTIVE SUBSTANCES.

Pharmacological action

Means, improve cerebral blood flow and cerebral metabolism. It inhibits the activity of phosphodiesterase, which contributes to the accumulation of cAMP in the tissues. Preferably has a vasodilating effect on brain vessels, due to a direct antispasmodic effect miotropnym. Systemic blood pressure decreased slightly. It improves blood circulation and microcirculation in the brain tissue, reduces platelet aggregation, It helps to normalize blood rheology. Improves tolerance of hypoxia brain cells, promoting oxygen transport to the tissues due to reduced affinity thereto erythrocytes, enhancing uptake and glucose metabolism. Increases the content of catecholamines in the brain tissue.

Pharmacokinetics

If ingestion is rapidly absorbed from the digestive tract. C_max in plasma is approximately 1 no. In parenteral administration, V_d is 5.3 l / kg. T_1/2 is about 5 no.

Testimony

Acute and chronic cerebral circulatory insufficiency. Encephalopathy, accompanied by memory disorders, dizziness, headache. traumatic encephalopathy. Vascular diseases of the retina and choroid. Hearing impairment of vascular or toxic origin, Meniere's disease, dizziness labyrinth origin. Vascular dystonia with climacteric syndrome.

Dosage regimen

Orally – by 5-10 mg 3 times / day.

The injection (mostly in acute conditions) single dose of 20 mg, with good endurance increase the dose over a 3-4 days before 1 mg / kg; length of treatment 10-14 days.

Pregnancy, hypersensitivity to vinpocetine.

For parenteral administration: severe coronary artery disease, severe arrhythmia.

Pregnancy and lactation

Contraindicated during pregnancy.

safety data, use during lactation are absent.

Cautions

To use caution inside with arrhythmia, angina, unstable when reduced blood pressure and vascular tone. Parenteral, usually, is used in severe cases, to improve the clinical picture, then move on ingestion. In chronic diseases vinpocetine are inside. In hemorrhagic cerebral stroke parenteral administration of vinpocetine is allowed only after the reduction of acute effects (usually 5-7 days).

Drug Interactions

In an application with warfarin reported a slight decrease in the anticoagulant action of warfarin.

With simultaneous parenteral administration of vinpocetine and heparin may increase the risk of bleeding.
