Introduction: The use of a laryngeal mask airway is associated with complications, such as a sore throat. This study aimed to evaluate the effect of taking the licophar pill on reducing sore throat due to laryngeal mask implantation in cataract surgery candidates. Methods: In this study, ۲۴۱ patients over ۱۸ years of age with cataract surgery and ASA Ι or ΙΙ were randomly divided into the intervention and control groups. The intervention group received one licophar pill half an hour before surgery; however, the control group received nothing. The sore throat severity was measured ۱, ۳, ۶, ۱۲, and ۲۴ h after surgery using the Visual-Analogue Scale (VAS). The data were analyzed in SPSS software (version ۱۶). Results: Out of ۲۴۱ patients, ۱۲۰ cases received licophar pills. There was no significant difference between the two groups in terms of gender; however, the mean age was lower in the control group. On the other hand, the rate of sore throat was significantly higher in the control group, compared to the intervention group. In addition, postoperative pain scores in the intervention vs. control group ۱, ۳, ۶, ۱۲, and ۲۴ h were ۰.۴۶۶ (۱.۴۵۴) vs. ۳.۸۴۲ (۳.۳۵۹), ۰.۳۸۳ (۱.۲۹۸) vs. ۳.۲۸۰ (۳.۰۵۶), ۰.۲۷۵ (۱.۱۰۲) vs. ۲.۶۹۴ (۲.۵۸۰), ۰.۲۰۰ (۰.۸۹۰) vs. ۲.۰۷۴ (۲.۲۷۱), and ۰.۱۰۸ (۰.۵۷۴) vs. ۱.۴۲۹ (۱.۷۱۴), respectively. Moreover, ۱۰۳ and ۴۰ patients in the intervention and control groups reported no pain (VAS=۰), respectively, ۱ h after surgery. Cocclusion: The present study showed that the use of licophar lozenge half an hour before surgery has a significant effect on reducing postoperative sore throat.
