Abstract
Isoniazid (50 or 100 mg kg^βl^ p.o.) inhibited the elimination of ethanol (0Β·5, 1Β·0, and 2Β·5 g kg^βl^ p.o.) from the plasma of rabbit, guinea pig, and rat. The effect of isoniazid, isonicotinic acid, Nβacetylisoniazid, Nβacetylhydrazine, N,Nβdiacetylhydrazine, and hydrazine on the in vitro metabolism of alcohol by rabbit liver alcohol dehydrogenase was examined. Only isoniazid, hydrazine, and acetylisoniazid showed significant inhibitory activity with I~50~'s of 17Β·7, 1Β·25, and 0Β·78 mmol 1^β1^ respectively. Intolerance to ethanol following isoniazid treatment was attributed to isoniazid inhibition of liver alcohol dehydrogenase.
