Antazoline is a histamine H1 receptor antagonist. It selectively bind to but does not activate histamine H1 receptors, thereby blocking the actions of endogenous histamine.
- Mechanism of action
Antazoline binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.
