[Controlled study of the analgesic efficacy of 2 drugs: tiapride versus aspirin].

Analgesic effect of aspirin 500 mg IM or IV and tiapride 300 mg IM or IV was compared in a double blind controlled study. Twenty-four patients with active cancer were each given both drugs successively, over 48 hours. No difference was demonstrated in analgesic effects of tiapride (14/24: 58%) and aspirin (11/24: 46%), or in toxicity which was minor for both drugs.
