Product Information

• Name: Azelastine N-oxide, mixture of diastereomers
• Brand: Biosynth
• Description: Azelastine N-oxide is a racemic form of azelastine, an antihistamine. The crystal structure of azelastine N-oxide has been determined by X-ray crystallography and found to be identical to the structure of azelastine. Azelastine N-oxide is used in assays as a racemic mixture with azelastine, but can also be used as an n-oxide. Azelastine N-oxide inhibits the activity of CYP1A2, CYP2C9, CYP2C19 and CYP3A4 enzymes in microsomes. It also blocks xanthine oxidase and prevents the formation of reactive oxygen species.
