Ebastine, is a H1 antihistamine with low potential for causing drowsiness. It does not penetrate the blood–brain barrier to a significant amount and thus combines an effective block of the H1 receptor in peripheral tissue with a low incidence of central side effects, i.e. seldom causing sedation or drowsiness. After oral administration, ebastine undergoes extensive first-pass metabolism by hepatic cytochrome P450 3A4 into its active carboxylic acid metabolite, carebastine. This conversion is practically complete. Ebastine is a second-generation H1 receptor antagonist that is indicated mainly for allergic rhinitis and chronic idiopathic urticaria.
