Product Overview

Being benzalkonium chloride (BAK)-free, it is formulated to offer improved ocular comfort, particularly for individuals with sensitive eyes or those requiring long-term use.
Mechanism Insights (How It Works)
- Histamine Receptor Blockade
Olopatadine selectively blocks H1 histamine receptors in ocular tissues, reducing allergic symptoms such as itching and redness. - Mast Cell Stabilization
It prevents mast cells from releasing inflammatory mediators like histamine and cytokines, reducing the progression of allergic reactions. - Inflammatory Response Control
By limiting mediator release, the drug helps calm ocular surface inflammation and provides sustained relief from allergy-related discomfort.
