چکیده
Description Vinpocetine (vinpocetine-ethyl apovincaminate) was synthesized in the late 1960s from the alkaloid vincamine, extracted from the leaf of the lesser periwinkle plant (Vinca minor). Vinpocetine was made available under the trade name Cavinton in 1978 and has since been used widely in Japan, Hungary, Germany, Poland, and Russia for the treatment of cerebrovascular-related pathologies. Several clinical studies have confirmed the neuroprotective effects of this compound.

Omeprazole does not change the oral bioavailability or pharmacokinetics of vinpocetine in rats.
Previous studies proved that food strongly enhanced the bioavailability of vinpocetine. Food may change the pharmacokinetics of a drug by affecting various factors, including gastrointestinal pH. However, the influence of proton pump inhibitor-induced pH alterations on vinpocetine pharmacokinetics is not known. The aim was to evaluate the influence of omeprazole on the pharmacokinetics of oral ...
متن کامل[11C]vinpocetine: a prospective peripheral benzodiazepine receptor ligand for primate PET studies.
Vinpocetine, a synthetic derivative of the Vinca minor alkaloid vincamine, is a widely used drug in neurological practice. We tested the hypothesis that vinpocetine binds to peripheral benzodiazepine binding sites (PBBS) and is therefore a potential ligand of PBBS. Positron emission tomography (PET) measurements in two cynomolgous monkeys showed that pretreatment with vinpocetine markedly reduc...
متن کاملThe Effect of Vinpocetine on Human Cytochrome P450 Isoenzymes by Using a Cocktail Method
Vinpocetine is a derivative of the alkaloid vincamine, which had been prescribed for chronic cerebral vascular ischemia and acute ischemic stroke or used as a dietary supplement for its several different mechanisms of biological activities. However, information on the cytochrome P450 (CYP) enzyme-mediated drug metabolism has not been previously studied. The present study was performed to invest...
متن کاملInhibitory Effects of Vinpocetine on the Progression of Atherosclerosis Are Mediated by Akt/NF-κB Dependent Mechanisms in apoE-/- Mice
BACKGROUND Recent studies have found additional roles for vinpocetine, a potent phosphodiesterase type I inhibitor, in anti-proliferation and anti-inflammation of vascular smooth muscle cells and cancer cells via different mechanisms. In this study, we attempted to investigate whether vinpocetine protected against atherosclerotic development in apoE(-/-) mice and explore the underlying anti-ath...
متن کاملVinpocetine and piracetam exert antinociceptive effect in visceral pain model in mice.
The effect of vinpocetine or piracetam on thermal and visceral pain was studied in mice. In the hot plate test, vinpocetine (0.9 and 1.8 mg/kg), but not piracetam, produced a reduction in nociceptive response. Vinpocetine (0.45-1.8 mg/kg, ip) or piracetam (75-300 mg/kg, ip) caused dose-dependent inhibition of the abdominal constrictions evoked by ip injection of acetic acid. The effect of vinpo...
