"Route of administration: oral
study duration: read description below
population: 48 male volunteers
ages: mean(std dev): 26(6.7)
Day 7 Alprazolam AUC_i/AUC (0-inf): 1.987
Day 7 4-OH-Alprazolam AUC_i/AUC (0-inf): .71
Description:
This study was conducted to determine the potential for an interaction between nefazodone, a new antidepressant, and alprazolam after single- and multiple-dose administration in a randomized, double-blind, parallel-group, placebo-controlled study in 48 healthy male volunteers. A group of 12 subjects received either placebo twice daily, 1 mg of alprazolam twice daily, 200 mg of nefazodone twice daily, or the combination of 1 mg of alprazolam and 200 mg of nefazodone twice daily for 7 days. Serial blood samples were collected after dosing on day 1 and day 7 and before the morning dose on days 4, 5, and 6 for the determination of alprazolam and its metabolites alpha-hydroxyalprazolam (AOH) and 4-hydroxyalprazolam (4OH) and nefazodone and its metabolites hydroxynefazodone (HO-nefazodone), m-chlorophenylpiperazine (mCPP), and a triazole dione metabolite (dione) by validated high-performance liquid chromatography methods. Steady-state levels in plasma were reached by day 4 for alprazolam, 4OH, nefazodone, HO-nefazodone, mCPP, and dione. Noncompartmental pharmacokinetic analysis showed that at steady state, alprazolam Cmax and AUCtau values significantly increased approximately twofold and 4OH Cmax and AUCtau values significantly decreased by 40 and 26%, respectively, when nefazodone was coadministered with alprazolam. There was no effect of alprazolam on the single-dose or steady-state pharmacokinetics of nefazodone, HO-nefazodone, or dione after the coadministration of alprazolam and nefazodone."
