Biodryl Syrup belongs to a class of medications called ‘expectorants’ used to treat 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, namely: 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 your airways. 

Biodryl Syrup is a combination of four drugs, namely: Ammonium chloride (expectorants), Diphenhydramine (antihistamine), Sodium citrate (mucolytic), and menthol (cooling agent). Ammonium chloride belongs to the class of expectorants that works by increasing the volume of fluid in the airways, reduce the stickiness of mucus, and helps to remove it from airways. Diphenhydramine belongs to the class of antihistamines (anti-allergic drugs) that works by blocking the action of histamine, a substance responsible for causing allergic reactions. Sodium citrate is a mucolytic agent (cough/sputum thinner) that works by thinning and loosening phlegm (mucus) in the lungs, windpipe, and nose. Thereby, it helps to cough out easily. Menthol is a cooling agent that produces a cooling sensation and provides relief from minor throat irritation.
