Résumé
The objective of this study was to compare the efficacy and safety of cough mixture containing pholcodeine and promethazine - Tixylix (CS1) to a cough mixture which has noscapine, ammonium chloride, and sodium citrate (CS2) as its constituents in treatment of children suffering from dry cough. A total of 208 patients were enrolled at 4 sites. Of these, 179 (94 receiving CS1 and 99 receiving CS2) completed the study. Results of this study suggest that both the cough mixtures were comparable as per evaluation of their primary parameters. According to global assessment for efficacy and tolerability by parents on Day 7, Group CS1 performed better than CS2. It was also observed that no AE was reported in Group CS1 as compared to 2 AEs in Group CS2. To conclude, cough mixture combination of pholcodeine and promethazine - Tixylix exhibited efficacy and safety that was comparable with cough mixture which has noscapine, ammonium chloride, and sodium citrate. It was proven to be efficacious, safe and well tolerated in the select population.
