Effect of food on the bioavailability of bromazepam following oral administration in healthy volunteers.
The effect of food on the rate and extent of bioavailability of bromazepam was examined in seven normal volunteers following a single oral dose of 10 mg bromazepam with 200 ml of water in the fasting and non-fasting states. Plasma concentrations of bromazepam were measured by high pressure liquid chromatography. A tmax value in a non-fasting state was prolonged from 2.3 +/- 0.3 (mean +/- S.E.M.) to 2.8 +/- 0.6 h but not significantly different (p greater than 0.05) whereas a Cmax value was significantly (p less than 0.05) decreased from 259 +/- 12.7 (mean +/- S.E.M.) to 169 +/- 13.9 ng/ml. The area under the plasma concentration-time curve in the non-fasting state was also significantly (p less than 0.05) decreased from 1844 +/- 145 (mean +/- S.E.M.) to 1233 +/- 98.1 ng.h/ml after oral administration of bromazepam.
