Summary
The effects of diphenhydramine, meclastine, and chlormezanone, alone or in combination with alcohol, on psychomotor skills related to driving have been investigated in 300 healthy volunteers. A choice reaction test and two coordination tests were employed. — Diphenhydramine caused sedation, partly independent of the dose, and slightly impaired psychomotor performance. Some subjects were exceptionally sensitive to diphenhydramine induced impairment of skills. It enhanced the effects of alcohol. — Meclastine did not impair psychomotor performance. A 1.5 mg dose did not enhance the effects of alcohol, but 3 mg did, although it was less potent than 50 mg of diphenhydramine. — Chlormezanone 200 mg had a relaxing effect which became apparent as a shortened reaction time at 30 min. Chlormezanone 400 mg did not affect psychomotor performance, nor did it enhance the effects of alcohol on psychomotor skills.
