Allerbep 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. Furthermore, bepotastine does not interact with serotonin, muscarinic, benzodiazepine, and beta-adrenergic receptor that would otherwise result in adverse reactions such as dry mouth or sonmolence.Onset of action = 0.25 hours;Duration of action = 12-24 hours;

Uses

Betastin is used for the treatment of itching associated with signs and symptoms of allergic conjunctivitis.

Allerbep is also used to associated treatment for these conditions: Pruritus

How Allerbep works

Because of a type 1 hypersensitivity reaction cascade that is triggered by antigen exposure, allergic conjunctivitis occurs. Allergen exposure is followed by conjunctival mast cell degranulation and histamine released as a result of the formation of complementary IgE cross-links on the conjunctiva. Due to the release of histamine, symptoms such as itching can be observed. Allerbep works to relieve itchy eyes by three primary mechanisms of action. It is a non-sedating, selective antagonist of the histamine 1 (H1) receptor, a mast cell stabilizer, and it suppresses the migration of eosinophils into inflamed tissues to prevent tissue damage and worsening of allergic inflammation of the conjunctiva.
