Description and Uses

Astemizole belongs to the second-generation class of non-sedating, non-anticholinergic antihistamines. Its non-sedating properties appear to result from its poor penetration of the blood brain barrier. As a result it shows no potentiation of CNS depressants, including alcohol. Its long half-life allows once-daily dosing.
