| Summary: | Background and Aims:
Postoperative nausea and vomiting (PONV) is a common complication after surgery. Preventing PONV in high-risk patients often requires a multimodal approach combining antiemetic drugs with diverse mechanisms. While aprepitant, a neurokinin-1 receptor antagonist, is recognised as highly effective for PONV prevention, uncertainties remain regarding its effectiveness.
Methods:
This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The analysis assessed the effectiveness of aprepitant (A), aprepitant plus ondansetron (AO) and aprepitant plus dexamethasone and ondansetron (ADO) in preventing PONV compared to ondansetron alone (O) or in combination with dexamethasone (DO).
Results:
In the analysis of 12 studies involving 2729 patients, aprepitant demonstrated significant efficacy in preventing PONV compared to ondansetron alone (A versus [vs.] O: PONV incidence 12.5% vs. 28.5%, relative risk [RR] = 0.45, P < 0.001; complete response rate 55.97% vs. 50.35%, RR = 1.13, P = 0.010). The combination of aprepitant with ondansetron (AO) also showed a significantly lower incidence of PONV compared to ondansetron alone (11.3% vs. 26.8%, RR = 0.43, P < 0.001) and a higher complete response rate (38.1% vs. 26.84%, RR = 1.41, P = 0.020). In addition, ADO significantly reduced PONV incidence compared to DO (ADO vs. DO: 13.63% vs. 35.38%, RR = 0.38, P = 0.006).
Conclusion:
Aprepitant, whether used alone or in combination with ondansetron or both ondansetron and dexamethasone, consistently outperforms ondansetron in achieving a complete response as it lowers vomiting rates and reduces the need for rescue therapy during the crucial 24–48-h postoperative period. |
