ABSTRACT

Introduction- The herbal drugs mentioned in classics for treatment of airway infections are better than modern drugs like anti-tussive, expectorants, mucolytics etc., as they have no any side effect. Aim: To evaluate acute oral toxicity on swiss albino mice and anti tussive effect in So2 induced cough model of kofasil Syrup (Anti-tussive poly-herbal formulation). Method: The present study was conducted according to OECD guideline AOT-425 to know single dose toxicity of Kofasil Syrup on swiss albino mice. IAEC No. for the study is SKPCPER/IAEC/2016-02/02. Each mouse was treated with a single oral dose of 2000 mg/kg of extract in sequence at 48 h intervals. Body weight of all animals was recorded once in a week. The anti tussive effect was evaluated in SO2 induced cough model in mice by method as describe by Miyagoshi et al., 1986 with modified and simplified. Results: Body weight of all animals did not reveal any significant change as compared to vehicle control group. Mortality was not observed in any animal of a group. Kofasil Syrup showed significant decrease in cough bouts in compression to standard treated (Codeine Sulphate) group. Conclusion: The study shows that Kofasil Syrup (Anti -tussive poly-herbal formulation) did not produce any toxic effect at dose of 2000 mg/kg. So No-Observed-Adverse-Effect-Level (NOAEL) of Kofasil Syrup is 2000 mg/kg. The significant decrease in cough bouts proves potential anti tussive activity of Kofasil Syrup.
