Livostin

Livostin - General Information

Livostin is a selective second-generation H1-receptor antagonist used for allergic conjunctivitis. Livostin was discovered at Janssen Pharmaceutica in 1979.

Pharmacology of Livostin

Livostin is a selective histamine H1-receptor antagonist exerting inhibitory effects on the release of chemical mediators from mast cells and on the chemotaxis of polymorphonuclear leukocytes and eosinophils. Both histamine and antigens induced conjunctivitis can be inhibited by levocabastine. Livostin can also reduce symptoms of allergic rhinitis by preventing an increase in vascular permeability of nasal mucosa.

Additional information about Livostin

Livostin Indication: As an ophthalmic for the temporary relief of the signs and symptoms of seasonal allergic conjunctivitis. Also used as a nasal spray for allergic rhinitis.
Mechanism Of Action: Livostin is a potent, selective histamine H1-receptor antagonist. It works by competing with histamine for H1-receptor sites on effector cells. It thereby prevents, but does not reverse, responses mediated by histamine alone. Livostin does not block histamine release but, rather, prevents histamine binding and activity. Livostin also binds neurotensin 2 receptors and serves as a neurotensin agonist. This can induce some degree of analgesia.
