Description:
Mechanism of Action: Naphazoline, an imidazoline derivative sympathomimetic with α-adrenergic activity, produces vasoconstriction. When applied topically to mucous membranes, it reduces swelling and congestion. It is often used in combination with antazoline, an ethylenediamine derivative antihistamine, in ophthalmic preparations. Antazoline may be used as the hydrochloride, phosphate, sulfate or mesilate salts in ophthalmic preprations, usually in a concentration of 0.5%.
Onset: Local vasoconstriction: within 10 minutes
Duration: Local vasoconstriction: 2-6 hr

Store at 20-25°C (68-77°F). Protect from light.
