: 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.: 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.: 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.

This article's objective is to present the latest evidence and information on the management of postoperative nausea and vomiting (PONV). PONV continues to affect 30% of the surgical population causing patient dissatisfaction, extending length of stay, and increasing overall costs. This review includes the introduction of 2 new intravenous formulations of antiemetics (amisulpride, aprepitant), updates on nontraditional therapies, suggestions for combination prophylaxis, emerging data on rescue treatment, and considerations for special populations and settings.
Despite advances in antiemetics and protocolized postoperative nausea vomiting (PONV) management, it remains one of the most common postoperative adverse events. In patients who developed PONV despite antiemetic prophylaxis, giving a rescue treatment from the same class of medication is known to be of limited efficacy. Given the widespread use of 5-HT3 antagonists as PONV prophylaxis, another class of effective intravenous rescue antiemetic is in dire need, especially when prophylaxis fails, and rescue medication is utilized.
The second of a two-part series, this article describes eight recently approved drugs, including the first drug approved for the treatment of SARS-CoV-2, a first-in-class HIV attachment inhibitor, and a new intravenous injection indicated for the treatment of acute pain in adults for whom other treatments are ineffective.
