Dextromethorphan Hydrobromide (Dextromethorphan HBr)

Dextromethorphan Hydrobromide (Dextromethorphan HBr) is a synthetic derivative of morphinan and a widely used antitussive agent that suppresses cough reflex. It acts centrally on the cough center in the medulla without causing typical opioid side effects such as analgesia or dependence. It is commonly formulated in syrups, tablets, lozenges, and combination cold and flu medications. Due to its rapid onset, good oral bioavailability, and well-tolerated safety profile, Dextromethorphan HBr is a preferred active pharmaceutical ingredient (API) in cough suppressant products worldwide.

It works by loosening and thinning mucus in the airways, making it easier to cough up and clear from the respiratory tract. It is widely utilized in cough syrups, tablets, and cold remedies. Recognized for its mucolytic and muscle-relaxant properties, Guaiphenesin is included in both prescription and over-the-counter medications worldwide.
