Effectively, good tolerance, less adverse reaction. Used for dizziness, headache, memory disorders, movement disorder, aphasia, hypertensive encephalopathy, etc.. Can also be used in brain blood circulation obstacle caused by mental or neurological symptoms.

Description   

Vinpocetine (42971-09-5) is a phosphodiesterase PDE1 inhibitor (IC50=21 μM).1?Also blocks voltage-gated Na+?channels, IC50=44.2 μM (potency similar to phenytoin), a mechanism which may contribute to its neuroprotective and anticonvulsant activity.2?It reduces inflammatory IL-1β and TNF-α expression in rat hippocampus.3?Displays beneficial effects in a rat model of cerebral ischemia-reperfusion injury.4?Vinpocetine exerts neuroprotective effects by suppressing microglial inflammation.5
