- Drug Entry
- Olopatadine
Olopatadine is a selective histamine H1 antagonist and mast cell stabilizer that works by attenuating inflammatory and allergic reactions. It is a structural analog of doxepin, which has a minimal anti-allergic activity.10 Olopatadine works by blocking the effects of histamine, which is a primary inflammatory mediator that causes inflammatory and allergic reactions. An ophthalmic solution of olopatadine was approved by the FDA and European Union for the treatment of seasonal and perennial allergic conjunctivitis in 1996 and 2002, respectively.2 In comparison to other anti-allergenic ophthalmic medications, olopatadine displays a good comfort and tolerability profile since it does not cause perturbation of cell membranes.6 Olopatadine is used for the symptomatic treatment of ocular itching associated with allergic conjunctivitis in ophthalmic formulations and seasonal allergic rhinitis in intranasal formulations. It is currently marketed under several brand names, including Pazeo, Patanase, and Opatanol.
