Clinical Response of Syrup Hydryllin® in Pakistani Subjects With Cough in Routine Practice

Globally, the prevalence of acute cough is 9 to 64%, whereas chronic cough is >10% in most countries or regions, ranging from 7.2%-33%. In Pakistan, a few studies have examined chronic cough resulting from specific occupations, such as those involving brick kilns, textile work, or gem cutting. Additionally, 15.8% of subjects in a periurban area of Karachi City, Pakistan with cough lasting ≥ 2 weeks were found to have pulmonary TB. Overall, to estimate the prevalence and incidence of different coughs, there is no data available based on the local population, and the data assessing the quality of life of patients with different coughs is not available. Locally, few studies were conducted on cough syrups with a small sample size. However, no real data is available for the symptomatic management of cough about the patient's quality of life related to different coughs. The current study is designed to assess the response of different strengths of Syrup Hydryllin ( Syrup Hydryllin & Hydryllin Sugar-Free (Diphenhydramine, Ammonium Chloride, Menthol, Aminophylline) and Syrup Hydryllin DM (Dextromethorphan & Diphenhydramine) in the symptomatic management of cough in routine practice by physicians. The study's main objective is to assess the quality of life of the subjects suffering from the different types of cough.
