title: d-Amphetamine and ethanol: a drug-drug interaction study.
abstract: The in vivo and in vitro effects of d-amphetamine on the specific activities of endogenous liver alcohol-(L-ADH) and aldehyde dehydrogenase (L-ADH) were studied using rat and mouse liver enzyme preparations. d-Amphetamine, 10(-4)M, noncompetitively inhibited rat and mouse L-ALDH in vitro. Mitochondrial L-ALDH was not affected by d-amphetamine in vivo and in vitro in both species studied. A noncompetitive inhibition of mouse L-ADH, occurred in vivo 16 hr after administration of d-amphetamine, 4 mg/kg, IP. A moderate, but not significant decline in specific activity of rat L-ADH was determined after injection of d-amphetamine, 4 mg/kg IP, showed a significant decrease in their blood and brain content of exogenously administered ethanol from corresponding saline-treated controls for the 60 min and 90 min periods after ethanol administration, respectively. The results show species differences in d-amphetamine action on liver enzymes studied and indicate that d-amphetamine can interfere in the metabolism of ethanol.
