An overview of intravenous amisulpride as a new therapeutic option for the prophylaxis and treatment of postoperative nausea and vomiting

Abstract

ABSTRACT Introduction Current therapies of postoperative nausea and vomiting (PONV) are based on a combination of antiemetics from different pharmacological classes. Dopamine receptor antagonists are one of the cornerstones of such multimodal antiemetic approach, with droperidol being the best studied representative of this group. Droperidol’s use has significantly declined after the FDA’s black-box warning in 2001 due to its QT-prolonging properties. Amisulpride is a promising antiemetic agent which could fill this gap. Areas covered In this review, the authors discuss the pharmacological profile as well as clinical safety and efficacy of intravenous amisulpride and its relevance in the management of PONV. The article is based on a Medline, ClinicalTrials.gov, and Cochrane Library search for studies on amisulpride conducted so far. Expert opinion Promising clinical results on Barhemsys®, an intravenous formulation of amisulpride, make it a potential future drug of choice from the dopamine receptor antagonist group, replacing droperidol after its safety concerns. Amisulpride’s success on the market will mostly be determined by its cost-effectiveness and it will likely find a brighter use on the US-market, where the black-box warning led to droperidol’s withdrawal, while in many European countries, droperidol is still being used as an antiemetic.
