Effect of ethanol on diazepam distribution in rat.

The effect of an acute oral dose of ethanol (3 g/kg), administered 30 min prior to oral administration of 14C-diazepam (5 mg/kg), on the fate of radioactivity in rats was examined. Ethanol pretreated rats possessed higher tissue levels at 60, 90 and 120 min than control animals. Blood, liver, kidney and plasma tissues showed 1.

Effects of thioridazine and diazepam on the pharmacokinetics of [14C]imipramine in rat: acute study.

The pharmacokinetics of [14C]imipramine (10 mg kg minus 1) were tested in male Wistar rats for interaction with thioridazine (16 mg kg minus 1) or diazepam (10 mg kg- minus 1). All drugs were administered orally with the test substances being given 40 min before [14C]imipramine dosing. Bile and urine were collected for 90 min after the radioactive drug was given.
