Ebastine
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.
