How It Works

This medicine combines two active ingredients. Naphazoline is a sympathomimetic amine that stimulates alpha-adrenergic receptors on the blood vessels of the conjunctiva, causing vasoconstriction and reducing redness and swelling. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, thereby reducing allergic symptoms such as itching, redness, and tearing.

Mechanism Steps

1
Vasoconstriction by naphazoline: Naphazoline stimulates alpha-adrenergic receptors on conjunctival blood vessels, causing them to constrict and reducing hyperemia.
2
Histamine receptor blockade by chlorpheniramine: Chlorpheniramine maleate competes with histamine for H1 receptors on cells in the eye, preventing histamine-mediated allergic responses like itching and vasodilation.
3
Reduction of allergic symptoms: The combined actions decrease redness, itching, and tearing associated with allergic conjunctivitis.
