Preparation of Sepestan Anti-cough Syrup and Comparison of its Effectiveness With Diphenhydramine Syrup in Treating Cough in Children With Upper Respiratory Tract Infection: A Double-blind Randomized Clinical Trial

Abstract

Background and Objectives Antihistamine drugs for acute upper respiratory tract infection treatment in children have many side effects. In this study, a anti-cough syrup was prepared from Cordia (Sepestan in Persian) extract and its effect was compared to that of diphenhydramine syrup on cough relief of children with upper respiratory tract infection. Subjects and Methods This double-blind randomized clinical trial was conducted on 124 children with upper respiratory tract infection aged 6-12 years referred to Abouzar Hospital in Ahvaz, Iran during 2019- 2021 in two treatment groups. The first group was given Sepestan syrup at a dose of 20 mg/kg/day and the second group received diphenhydramine syrup at a dose of 5 mg/kg/day in four dosages. For three days, the number and severity of day-time and night-time coughs were examined and the data were analyzed with independent t-test and chi-square test in SPSS software, version 24. Results The number and severity of day-time and night-time coughs in the group received Sepestan syrup significantly decreased compared to the diphenhydramine group, without any side effects (P<0.001). Conclusion High polysaccharides, strong antioxidants, and anti-inflammatory compounds of Sepestan can reduce throat irritation and soften the chest. The mucilage in the Sepestan extract can dissolve in water and produce a viscous substance such as gelatin that cause softening of the breast and expectoration.
