Carebastine

The active metabolite of ebastine, a second-generation H1 antihistamine in use since 1990: it is formed in the liver by the enzyme CYP3A4 and is the molecule that does the work against allergic rhinitis and urticaria. This family brings together the active ingredient and labelled standards.

Did you know?The conversion of ebastine into carebastine, a carboxylic acid, is practically complete on the first pass through the liver: whoever takes ebastine in effect receives carebastine, which stays in circulation for 15-19 hours.
