Interaction between ethanol and antihistamines: 3. mebhydrolin

We used 17 student volunteers in an experiment to investigate the effects of orally administered mebhydrolin (0.71 mg/kg), alone and in combination with ethanol (0.75 g/kg), on perceptual, cognitive and motor functions. Mebhydrolin did not significantly modify performance when given alone, but showed evidence of enhancing ethanol-induced performance deficits. Histamine challenge experiments indicated that the dose of mebhydrolin used exerted an antihistaminic effect over the period of the ethanol interaction study.
