Tiapride versus metoclopramide: comparison after minor gynaecological surgery

Tiapride (Tiapridal, Delagrange), a dopaminergic D2 receptor blocking agent having anxiolytic, sedative, antiemetic and analgesic properties was compared with metoclopramide and placebo in a randomized double-blind trial to determine its effects on post-operative nausea, vomiting, and sedation. The agents were given intravenously immediately before induction of anaesthesia to 75 women scheduled for minor elective gynaecological surgery. A standardized anaesthetic technique was used in all the patients. In the recovery room anti-emetic and sedative effects of tiapride and metoclopramide were similar and significantly better (P < 0.001) than placebo. In the ward at the end of 5 h anti-emetic (P < 0.05), and sedative (P < 0.01) effects of tiapride were significantly better than both metoclopramide and placebo.
