Mechanism of action

Olopatadine works through dual action: it competitively antagonizes H1 receptors on ocular tissues to block histamine-induced symptoms, and simultaneously stabilizes mast cells to prevent degranulation and release of inflammatory mediators. This combination provides both rapid symptom relief and sustained anti-allergic effects for ocular allergy management.
