Vinpocetine (brand names: Cavinton, Intelectol; chemical name: ethyl apovincaminate) is a semisynthetic derivative of vincamine, which is extracted from the Periwinkle plant. It increases cerebral blood flow and is said to improve memory.

It is an inhibitor of phosphodiesterases I and IV, with an IC50|IC50 of approximately 10-5 M.

The substance is widely sold as a supplement; however, there appears to be some controversy over the possibility of adverse reaction, and low initial dose is recommended by some retailers. Vinpocetin is included in many performance-enhancing supplements to help with delivery of nutrients to muscles after workout. There is one isolated claim of agranulocytosis.

Health and physiological applications of vinpocetine[edit | edit source]

Side effects[edit | edit source]

Overall, Vinpocetine side effects reported in the literature are rare, usually minor, frequently disappear with prolonged use, and rarely require discontinuance of the drug.

Stomach/ GI upset; dry mouth, rapid heart beat, low blood pressure, and rash/ hives are the main (rarely occurring) reported side effects. There have been no real adverse effects to this drug during human trials.

Not recommended for pregnant women (at doses higher than 2-5 mg).

Care should be taken when it is taken with other nootropics. It is always recommended that a physician be consulted before use.

Dosage[edit | edit source]

It is recommended that the first-time user ingests only 2- 5 mg of vinpocetine to make sure they are not hypersensitive to it. The user may then increase the dosage to 10-30 mg a day (which may, although very rarely, cause some side effects).
