The active substance of Cavinton – Vinpocetine. It is a plant alkaloid derived from the flower called periwinkle. The therapeutic properties of this plant have long been known in folk medicine.
Vinpocetine belongs to the class of nootropic drugs that is, drugs that affect the brain. It has cerebrovasculature and cerebroprotective effect. The main effects of Vinpocetine – improve metabolism and blood circulation in the nervous tissue, antioxidant activity. Also, the drug improves blood properties.
Among the demonstrated a drug’s metabolic effects, the following should be noted:
- the decrease of the degree of damage caused by amino acids
- inhibition of the action of sodium and calcium channels,
- stimulation of the neuroprotective effect of chlorpromazine
- improving the consumption and metabolism of glucose and oxygen,
- stimulation of the metabolism of serotonin and norepinephrine
- increasing the concentration of the energy molecule ATP in the brain tissue,
- the increasing resistance of nervous cells to hypoxia.
Effects associated with improve blood circulation:
- reduced resistance of cerebral vessels,
- reducing the tendency of platelet aggregation,
- reduction of pathological blood viscosity,
- increasing the deformability of red blood cells,
- blocking the uptake of adenosine by erythrocytes
- impact of oxygen by erythrocytes
- optimize blood circulation in small capillaries (microcirculation).
The drug has no significant effect on systemic blood flow without changing blood pressure, heart rate.
An important feature of the drug is that it is most active in the affected ischemic pathology of the brain.
The drug readily crosses the blood-brain barrier, which explains its nootropic effect. It is absorbed in the intestines within one hour. Two-fifths of the drug is excreted through the intestines, and three fifths through the kidneys.

- the memory impairment.
Also Cavinton is often used in the recovery after traumatic brain injury.
Ophthalmic the drug is used for:
- spasm of the retinal vessels,
- atherosclerotic lesions of the ocular vessels
- thrombosis and embolism of ocular vessels,
- degenerative changes in the eye tissues,
- secondary glaucoma.
In otolaryngological practice, the drug may be useful in the following cases:
- hearing loss due to advanced age, heart failure or toxic injury of the tissues;
- Meniere’s disease;
- system dizziness;
- vasovegetative disorders during menopause;
- kohleovestibularnyi syndrome.
Cavinton is a relatively safe drug, and it can be applied even people in serious condition. Neither renal nor hepatic failure may not be a contraindication to taking the drug. You cannot take only in severe forms of ischemic heart disease and arrhythmias.
A relative contraindication is the children’s age (under 18). In practice, however, many pediatricians prescribe it to children, if there is no other alternative. However, to treat this drug children should not be, because only the doctor can find the necessary for a child the dose and form of the drug, taking into account the patient’s age and type of disease.
