Amisulpride: A New Drug for Management of Postoperative Nausea and Vomiting

OBJECTIVE: To review the pharmacology, efficacy, and safety of amisulpride and determine its role in the management of postoperative nausea and vomiting (PONV). DATA SOURCES: was conducted. STUDY SELECTION AND DATA EXTRACTION: Relevant reports on intravenous amisulpride were included. DATA SYNTHESIS: Six clinical trials were evaluated. In 4 trials on the prevention of PONV, a greater percentage of patients who received amisulpride 5 mg compared with placebo experienced a complete response (44%-60% vs 31%-33%, respectively, when used as monotherapy; 58% vs 47%, respectively, when used in combination with another antiemetic). In 2 trials on the treatment of PONV, a significantly greater percentage of patients who received amisulpride 10 mg compared with placebo experienced a complete response (31.4% vs 21.5%, respectively, in patients who had not received prophylaxis; 41.7% vs 28.5%, respectively, in patients who had received prophylaxis). Adverse effects included infusion site pain, chills, hypokalemia, procedural hypotension, and abdominal distension. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Amisulpride is effective for the management of PONV and may be less likely to cause QT prolongation and extrapyramidal symptoms than other dopamine antagonists. Additional information is needed on its use for chemotherapy-induced nausea and vomiting and in children. CONCLUSIONS: Amisulpride is an important new option for the multimodal management of PONV in adults, and it may be the preferred dopamine antagonist because of the more favorable safety profile that results from its unique pharmacological properties.
