Olopatadina Stallpharma (Olopatadine)

Olopatadine is an antihistamine that acts on ocular allergic pathways to reduce inflammation and itching.

• Allergic conjunctivitis: alleviates redness, itching and watery discharge.
• Seasonal allergic eye disease: provides relief from seasonal pollen‑induced eye symptoms.
• Vernal keratoconjunctivitis: helps control chronic eye irritation in affected individuals.
• Contact lens‑related allergy: reduces discomfort for lens wearers with allergic responses.
• Post‑operative ocular inflammation: supports reduction of inflammation after eye procedures.

• Olopatadine blocks histamine H1 receptors on mast cells and conjunctival tissues, preventing the release of histamine and other inflammatory mediators. It also exhibits mast‑cell stabilising activity, which limits the cascade of allergic inflammation in the eye, thereby reducing redness, itching and swelling.

Olopatadine eye drops may produce a range of ocular and systemic reactions.
