Chloropyramine
Chloropyramine
Chloropyramine (pronounced klor-oh-py-ra-meen) is a first-generation H1-antihistamine that is used in the treatment of allergic conditions such as rhinitis and urticaria. It is also used as an adjunctive therapy in anaphylactic shock.
Etymology
The term "Chloropyramine" is derived from its chemical structure. "Chloro" refers to the presence of a chlorine atom, while "pyramine" is a reference to its pyramidal amine structure.
Pharmacology
Chloropyramine works by blocking the action of histamine, a substance in the body that causes allergic symptoms. It is a competitive antagonist of the H1 histamine receptor, meaning it prevents histamine from binding to this receptor and thus inhibits the allergic response.
