Abstract

Introduction: Postoperative nausea and vomiting (PONV) is a common complication following anesthesia. Penehyclidine hydrochloride (PHC), an anticholinergic medication, selectively inhibits the M1 Muscarinic and M3 Muscarinic receptors involved in the nausea and vomiting pathways. This study aims to evaluate the efficacy of PHC in preventing PONV and its potential advantages over existing treatments.

Methods: This study investigated the efficacy and safety of PHC in preventing PONV by analyzing randomized controlled trials (RCTs) identified through a comprehensive search of the PubMed, Scopus, Web of Science, and Cochrane Library databases up to December 2024.

Results: Five RCTs involving 979 patients were included. Compared to the control group, PHC reduced the incidence of PONV in the first 24-72 hours after surgery (RR: 0.64, 95% CI [0.50, 0.82], p = 0.0004) and the requirement of rescue antiemetics (RR: 0.46, 95% CI [0.22, 0.96], p = 0.04). However, PHC significantly increased the incidence of dry mouth (RR: 2.64, 95% CI [1.98, 3.5], p < 0.00001). No significant differences were observed between the two groups regarding other secondary outcomes. Risk of bias assessment was done using RoB2.

Conclusions: PHC shows promising efficacy in reducing PONV and the need for antiemetic medications. Further large-scale RCTs are necessary to verify these results and determine the optimal dose.
