Sample Use Guides

In Vivo Use Guide
Out-patient Treatment of hypertension with Protoveratrine A: The duration of treatment has been from one month to as long as two years (mean nine months). The total treatment months were 155. The dosage employed varied from 0.5 to 3.6 mg daily. The drug was taken three times daily after meals and an additional dose often on retiring.
Route of Administration: Oral
In Vitro Use Guide
Curator's Comment: Protoveratrine A (10(-4) M), on the other hand, elevated the efflux of glutamate, GABA and possibly aspartate when these amino acids were synthesised from glucose, but not when acetate was the labelled precursor. https://www.ncbi.nlm.nih.gov/pubmed/913529
Protoveratrine A increased the release of gamma-amino[3H]butyrate from small slices of rat cerebral cortex. This effect increased with increasing protoveratrine concentration, reaching a maximum at 100 uM. 2. Removal of Ca2+ from the superfusing medium did not change the increase in release due to 10 uM-protoveratrine.
