🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary actions. Naphazoline is an alpha-adrenergic agonist that stimulates alpha receptors on conjunctival blood vessels, causing vasoconstriction and reducing hyperemia and edema. Chlorpheniramine maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, thereby reducing itching, sneezing, and allergic responses. Together, they provide rapid symptomatic relief from allergic and irritant conjunctivitis.
