Bioavailability of Oxazepam: Absence of Influence of Food Intake

Abstract

The possible influence of food intake on the bioavailability of the anxiolytic drug oxazepam was assessed in eight healthy volunteers taking a single dose of the drug both on an empty stomach and together with a standardized breakfast meal. The serum concentrations of oxazepam were determined by gas chromatography on samples obtained before, and at numerous occasions up to 48 hours after drug administration. The results indicate that concomitant food intake has no essential influence on the bioavailability of oxazepam.
