Chlorpheniramine Maleate+dextromethorphan Hydrobromide+phenylephrine Hydrochloride is used to treat dry cough. Coughing (dry or productive) is the body’s way of clearing irritants (like allergens, mucus, or smoke) from airways and preventing infection. There are two types of coughs: dry cough and chesty cough. A dry cough is tickly and doesn’t produce any vicious or thick mucus, while a chesty cough (wet cough) means mucous or sputum is produced to help clear the airways.

Chlorpheniramine Maleate+dextromethorphan Hydrobromide+phenylephrine Hydrochloride is a combination of three drugs: Chlorpheniramine maleate (antihistamine), Phenylephrine hydrochloride (decongestant), and Dextromethorphan hydrobromide (cough suppressant). Chlorpheniramine maleate works by blocking the action of histamine, a substance responsible for causing allergic reactions. Phenylephrine hydrochloride helps in shrinking the blood vessels located in the nasal passage, thereby reducing the stuffy nose. Dextromethorphan hydrobromide works by blocking the transmission of nerve signals from the cough centre in the brain to the muscles that produce cough. Together, it helps to provide relief from dry cough.
