Reswas Syrup 120 ml is used to treat dry cough. It is a member of the class of drugs known as "cough and cold medicines." The body uses coughing, whether it's productive or dry, to remove irritants from the airways and guard against infection. Dry cough and chesty cough are the two different forms of coughs. A chesty cough (wet cough) means mucous or sputum is generated to help clear your airways, but a dry cough is tickly and doesn't produce any nasty or thick mucus. Levodropropizine (a cough suppressant) and chlorpheniramine maleate are both present in Reswas Syrup 120 ml (antihistamine). Levodropropizine is a member of the class of cough suppressants that prevents the nerve signals from the brain's cough centre from reaching the throat.Disclaimer:For more information contact your physician.
