[Interaction between tiapride and alcohol in man].

Results of a study in nine alcoholic patients designed to investigate the effects on wakefulness of tiapride combined with alcohol are presented. Each patient was given successively alcohol, tiapride, and both. Changes in certain psychomotor performances during each of these three periods are described. In the study patients, the tiapride-alcohol combination produced no detrimental effect on wakefulness; on the contrary, results of one of the tests were improved.
