Study Summary

This is a 4-week sequential drug interaction study to measure the effects of American ginseng on efavirenz pharmacokinetics using steady-state 24-hour Area Under the Curve (AUC) and Cmax as the primary comparison measures in healthy male volunteers. Efavirenz Cmin, T1/2, tmax, and clearance will also be assessed as secondary outcome measures. This study is a phase I, prospective, within-subject, fixed-order, two-period, multiple dose, open label, drug interaction study, to determine the stead-state plasma pharmacokinetic profile of efavirenz before and after concurrent treatment with American ginseng. The investigators hypothesis is that concurrent oral administration of American ginseng for up to 14 days will not significantly alter the steady-state plasma pharmacokinetic of efavirenz.

Primary Outcome

Compare efavirenz AUC0-24 and Cmax when dosed alone at 600 mg daily, to steady-state efavirenz AUC0-24 and Cmax dosed at 600 mg daily and given concurrently with American ginseng 3000 mg daily.
