Azelastine HCl is a potent, second-generation, selective, histamine antagonist. Target: Histamine Receptor Azelastine is a selective H(1)-receptor antagonist that inhibits histamine release and interferes with activation of several other mediators of allergic inflammation.

Background Information

Azelastine hydrochloride (Astelin) is a potent, second-generation, selective, histamine antagonist. Azelastine hydrochloride (Astelin) has a triple mode of action: Anti-histamine effect, mast-cell stabilizing effect and anti-inflammatory effect. Azelastine hydrochloride (Astelin) has a rapid onset of action: 15 minutes with the nasal spray and 3 minutes with the eye drops. The effect lasts for 12 hours. ......by AbMole BioScience

Azelastine HCl is a potent and selective H1-receptor antagonist, with antiallergic effects related to histamine antagonism, and further antiallergic and anti-inflammatory effects unrelated to H1-receptor binding. Azelastine HCl is an activator of NF-kB activator. Azelastine hydrochloride has been used in a study to investigate the potential of polymeric microspheres for treatment of allergic conjunctivitis. Azelastine is shown to block secretion of IL-6, IL-8, and TNF alpha from mast cells by inhibiting NF-κB activation. ......by MedKoo Biosciences, Inc.
