Pharmacology
Olopatadine, an antihistamine, works by blocking the action of histamine in the body, which reduces allergy symptoms. Olopatadine hydrochloride treats sneezing, itching, runny nose, and other nasal symptoms of allergies. Mode of Action : Olopatadine is an anti-allergic molecule that works via several mechanisms. As a mast cell stabilizer, it stabilizes rodent basophils and human conjunctival mast cells and inhibits the immunologically-stimulated release of histamine. Olopatadine acts as an antagonist at the histamine H1 receptors with high selectivity, Upon binding, olopatadine blocks the H1 receptor signaling pathway, inhibiting the release of inflammatory mediators, such as tryptase, prostaglandin D2, TNF-alpha, as well as pro-inflammatory cytokines. Pharmacokinetics : Absorption: Olopatadine was absorbed with individual peak plasma concentrations observed between 30 minutes and 1 hour after twice daily intranasal administration of Olopatadine Nasal Spray. Distribution: The protein binding of olopatadine was moderate at approximately 55% in human serum, and independent of drug concentration over the range of 0.1 to 1000 ng/mL. Metabolism: Olopatadine is not extensively metabolized. Based on plasma metabolite profiles of olopatadine, at least six minor metabolites circulate in human plasma. Elimination: The plasma elimination half-life of olopatadine is 8 to 12 hours. Olopatadine is mainly eliminated through urinary excretion
