HIDE SMILES / InChI
Bepotastine is a non-sedating, selective antagonist of the histamine 1 (H1) receptor. It belongs to the second-generation piperidine chemical class. It is a mast cell stabilizer and suppresses the migration of eosinophils into inflamed tissues. Bepotastine was approved in Japan for use in the treatment of allergic rhinitis and uriticaria/puritus in July 2000 and January 2002, respectively, and is marketed by Tanabe Seiyaku Co., Ltd. under the brand name Talion. It is available in oral and opthalmic dosage forms in Japan. The opthalmic solution is FDA approved since Sept 8, 2009 and is under the brand name Bepreve.

CNS Activity

Curator's Comment: Because of limited systemic absorption and poor blood-brain barrier penetration, the incidence of drowsiness with oral bepotastine besilate is low in comparison with other oral antihistamine products such as loratadine and cetirizine.
