Abstract:
AIMS:To obtain in vivo evidence for the involvement of cytochrome P450 (CYP) 3A4 in the metabolism of brotizolam. METHODS:Fourteen healthy male volunteers received erythromycin 1200 mg day(-1) or placebo for 7 days in a double-blind randomized crossover manner. On the 6th day they received a single oral 0.5-mg dose of brotizolam, and blood samplings were performed for 24 h. RESULTS:Erythromycin treatment significantly increased the peak plasma concentration (P < 0.05), total area under the plasma concentration-time curve (P < 0.01), and elimination half-life (P < 0.01) of brotizolam. CONCLUSIONS:The present study provides in vivo evidence for the involvement of CYP3A4 in brotizolam metabolism.
