Application
Olopatadine hydrochloride USP reference standard, intended for use in specified quality tests and assays as specified in the USP compendia.
Biochem/physiol Actions
Olopatadine is a histamine H1 receptor antagonist and mast cell stabilizer. The low level of occupancy H1 receptors in the brain explains the low sedation effect of olopatidine. It is believed that olopatidine is a substrate for P-glycoprotein, which limits its brain penetration.
