Ebastine (trade names Evastin Kestine Ebastel Aleva Ebatrol) 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.The patent in which the structure of ebastine is first mentioned is in Europe and in the US.
