Efficacy and safety of Aprepitant-containing triple therapy for the prevention and treatment of chemotherapy-induced nausea and vomiting: A meta-analysis

BACKGROUND: Most cancer patients suffer from the pain of chemotherapy-induced nausea and vomiting (CINV). This meta-analysis was performed to evaluate the efficacy and safety of a regimen consisting of aprepitant, dexamethasone, and 5-HT3 receptor antagonists in the prevention and treatment of CINV. METHODS: A systematic literature search was conducted across multiple databases, including PubMed, EMbase, Cochrane Library, MEDLINE, CENTRAL, HEED, CNKI, Wanfang, and VIP, to identify randomized controlled trials (RCTs) investigating the use of triple therapy (aprepitant, 5-HT(3) receptor antagonist, and dexamethasone) to prevent and treat CINV. Meta-analysis was performed using RevMan 5.4 and Stata17 software, employing either a fixed-effect or random-effect model based on statistical heterogeneity. RESULTS: A meta-analysis of 23 randomized controlled trials (RCTs) involving 7956 patients was conducted. Efficacy: Results showed significantly improved complete responses (CRs) for CINV in the test group versus the control group in the overall, acute, and delayed phases. Furthermore, in the test group, substantial alleviation of nausea symptoms was observed in the delayed and overall phases but not in the acute phase. Safety: There was no statistically significant difference in the incidence of febrile neutropenia, diarrhea, anorexia, and headache between the 2 groups. The incidence of fatigue and hiccups in the test group was higher than that in the control group; however, the incidence of constipation was significantly lower. CONCLUSIONS: Aprepitant-containing triple therapy is highly effective in the prevention and treatment of CINV, with reliable medication safety.
