What is Olopatadine?
Olopatadine, the active ingredient in Optamont, is a selective H1‑receptor antagonist presented as an ophthalmic solution for ocular use. It is formulated to alleviate eye discomfort caused by allergic reactions, reducing redness, swelling, and itching by stabilizing mast cells and blocking histamine release in the conjunctiva.
GNH USA supplies Optamont as a licensed, GDP‑compliant international pharmaceutical supplier, providing the product to hospitals, pharmacies and clinics worldwide under strict quality standards. The product complies with European Union regulations and is available as an over‑the‑counter eye drop.
What is Olopatadine used for?
Olopatadine acts on ocular allergic pathways to relieve inflammation and itching.
Allergic conjunctivitis: reduces redness, swelling and itching in the conjunctiva. Seasonal allergic conjunctivitis: provides rapid relief of eye symptoms triggered by seasonal allergens. Ocular itching due to allergy: alleviates itching and discomfort caused by allergic reactions in the eye.
