Cavinton forte (Vinpocetine)

 

Vinpocetine, also known under the brand name Cavinton, is an alkaloid derived from Vinca Minor plant which is also known as periwinkle. It was first isolated in 1975 in Hungary, and the commercial production of the drug started in 1978 by the Gedeon Richter company.

Vinpocetine often used in the medical practice as a cerebral vasodilator, a substance that improves cerebral blood flow. The indications for use is cerebrovascular disorders, stroke consequences and age-related impairment of cognitive functions. This drug considered safer than other cerebrovasodilators because it increases brain blood flow without redistribution of the blood flow away from underperfused brain regions.

As a vasodilator substance, Vinpocetine lowers the blood viscosity and relaxes the vascular smooth muscle thus improving cerebral blood flow and retinal microcirculation. It is somewhat similar to its effects to Ginkgo Biloba extract, another substance of the herbal origin used as a Nootropic supplement. Both Vinpocetine and Ginkgo are a possible treatment for tinnitus. The drug exhibits anticonvulsant and neuroprotective properties. Some people use Vinpocetine as Nootropic supplement that can improve memory and focus.
