Olopatadine Hydrochloride Eye DropsThird Party Manufacturing in India

Olopatadine hydrochloride works through multiple distinct mechanisms to provide relief from allergic conjunctivitis. It acts as a potent, selective histamine H1 receptor antagonist, blocking histamine from binding to receptors on the conjunctival surface and preventing the itching, redness, and swelling that characterize allergic reactions. Additionally, olopatadine functions as a mast cell stabilizer, inhibiting the immunologically-stimulated release of pro-inflammatory mediators including histamine, tryptase, prostaglandin D2, and tumor necrosis factor-alpha from human conjunctival mast cells. It also decreases chemotaxis and inhibits eosinophil activation. This dual mechanism provides both prophylactic and therapeutic benefits.

Therapeutic Uses

Olopatadine Hydrochloride Eye Drops are prescribed for:

• Seasonal Allergic Conjunctivitis (SAC): Itching, redness, and watering of the eyes triggered by seasonal allergens such as pollens, grass, and mold spores.
• Perennial Allergic Conjunctivitis (PAC): Year-round allergic symptoms caused by indoor allergens like dust mites, pet dander, and cockroach debris.
• Ocular Itching: The primary indication is the relief of ocular itching associated with allergic conjunctivitis, with rapid onset of action.
