In Vivo Use Guide
Curator's Comment: https://clinicaltrials.gov/ct2/show/NCT01704196?term=NEPICASTAT&rank=3
Post Traumatic Stress Disorder: 120 mg/day Cocaine Dependence: Nepicastat 120 mg and 100 mg riboflavin (once per day) for 11 weeks
Route of Administration: Oral
In Vitro Use Guide
Nepicastat produced concentration-dependent inhibition of bovine and human dopamine-beta-hydroxylase activity. The calculated IC50s for nepicastat were 8.5+0.8 nM and 9.0+0.8 nM for the bovine and human enzyme, respectively.
