Antazoline is a 1st generation antihistamine with anticholinergic properties used to relieve nasal congestion and in eye drops, usually in combination with naphazoline, to relieve the symptoms of allergic conjunctivitis.[1] To treat allergic conjunctivitis, antazoline can be combined in a solution with tetryzoline.[2] The drug is a Histamine H1 receptor antagonist:[3] selectively binding to but not activating the receptor, thereby blocking the actions of endogenous histamine and subsequently leading to the temporary relief of the negative symptoms brought on by histamine.
