Lupihist DM Plus Syrup 60 ml, which is a member of the class of drugs known as "cough and cold medicines," is to treat dry cough. The body uses coughing, whether it is 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 the airways, whereas a dry cough is tickly and doesn't produce any nasty or thick mucus. Chlorpheniramine Maleate (Antihistamine), Phenylephrine Hydrochloride (Decongestant), and Dextromethorphan Hydrobromide are the three medications included in Lupihist DM Plus Syrup 60 ml (cough suppressant). Histamine, the chemical responsible for allergies, is inhibited by chlorpheniramine maleate.Disclaimer:For more information contact your physician.
