Abstract Eight healthy male volunteers received chlordiazepoxide HCl orally at a dosage of 10 mg every 8 hr over a period of 21 days. On day 22, the regimen was changed to 30 mg every 24 hr for an additional 15 days. Plasma concentrations of chlordiazepoxide and its metabolites desmethyl-chlordiazepoxide, demoxepam, and desoxydemoxepam were measured during 14 of the 36 treatment days. Chlordiazepoxide plasma concentration- time data were consistent with first-order absorption and complete bioavailability. The harmonic mean absorption half-life was 12.3 min. Disposition of chlordiazepoxide was described by a two-compartment open model with a harmonic mean terminal exponential half-life of 10.1 hr. Average steady — state plasma levels of chlordiazepoxide, desmethylchlordiazepoxide, and demoxepam were approximately 0.75, 0.54, and 0.36 μg/ml, respectively.
