What is "bromazine"

n. A particular antihistamine drug, a brominated derivative of diphenhydramine.

Bromazine (trade names Ambrodyl, Ambrodil and others), also known as bromodiphenhydramine, is an antihistamine and anticholinergic. It is a halogenated form of diphenhydramine and in many respects is somewhat stronger than the parent compound. The other three halogenated diphenhydramine derivatives are used in research and chlorodiphenhydramine is also marketed with iododiphenhydramine being a much less common pharmaceutical.
