naphazoline + chlorpheniramine + benzalkonium

Naphazoline + chlorpheniramine + benzalkonium is a fixed-dose combination ophthalmic solution used for the temporary relief of symptoms associated with allergic conjunctivitis and eye irritation. **Naphazoline hydrochloride** is a sympathomimetic amine that acts as a potent vasoconstrictor by stimulating alpha-adrenergic receptors, thereby reducing ocular congestion and redness. **Chlorpheniramine maleate** is a first-generation alkylamine antihistamine that provides relief from allergic symptoms such as itching, watering, and puffiness by competitively antagonizing histamine H1 receptors. **Benzalkonium chloride** is a quaternary ammonium compound primarily included in the formulation as a preservative with antimicrobial properties, though it may also serve as an antiseptic in certain topical formulations. This combination is widely available as an over-the-counter (OTC) medication in various international markets, including India and Japan, to treat eye irritation caused by hay fever, pollen, and animal dander.
