How It Works

This medicine combines two active ingredients with complementary mechanisms. Naphazoline is an alpha-adrenergic agonist that stimulates alpha receptors on the blood vessels of the conjunctiva, causing vasoconstriction and reducing hyperemia and edema. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, thereby preventing histamine-mediated effects such as itching, vasodilation, and increased vascular permeability. Together, they provide symptomatic relief from allergic conjunctivitis.

Mechanism Steps

1
Vasoconstriction by naphazoline: Naphazoline binds to alpha-adrenergic receptors on conjunctival arterioles, causing them to constrict and thereby reducing blood flow and redness.
2
Histamine receptor blockade by chlorpheniramine: Chlorpheniramine maleate competes with histamine for H1 receptors on cells in the eye, preventing histamine from triggering itching, vasodilation, and increased permeability.
3
Symptom relief: The combined actions lead to rapid reduction in eye redness, itching, and watering associated with allergic conjunctivitis.
