Azelastine Chemical Properties,Usage,Production

Description

Azelastine has potent, long-lasting histamine H1-receptor blocking activity and several other interesting anti-inflammatory properties related to its antiallergic efficacy .

Uses

anesthetic, anticonvulsant

Definition

ChEBI: A phthalazine compound having an oxo substituent at the 1-position, a 1-methylazepan-4-yl group at the 2-position and a 4-chlorobenzyl substituent at the 4-position.

brand name

Astelin (Medpointe); Optivar (Medpointe).

Clinical Use

Azelastine, although not a close structural analogue to the benzimidazoles, has some structural similarities to them. It is used as a nasal spray for allergic rhinitis and as eye drops for allergic conjunctivitis.Like olopatadine, azelastine also stabilizes mast cells, preventing degranulation and subsequent release of histamine, leukotrienes, and PGD2. It is available in Europe for systemic use in the treatment of asthma and seasonal allergies. Besides antihistaminic effects, it also may block release of histamine and other inflammatory mediators from mast cells. When administered orally, the N-dealkylated metabolite appears to contribute significantly to its pharmacological effects.

Safety Profile

Poison by ingestion,subcutaneous, intravenous, and intraperitoneal routes.Experimental reproductive effects. When heated todecomposition it emits toxic fumes of NOx and Cl- .
