<unk>  (trade names Claritin-D, Clarinase, Clarinase Repetabs, Lorinase, Rhinos SR) is an orally administered combination drug used for the treatment of allergic rhinitis and the common cold. This drug can be bought "over the counter" in some countries (United States, Hong Kong), but it is restricted to prescription in others (Czech Republic, Israel). * Pseudoephedrine, one of the naturally occurring alkaloids of ephedra, is a sympathomimetic used as a decongestant. It produces a decongestant effect that is facilitated by the vasoconstriction in the mucosal capillaries of the upper respiratory areas. * Loratadine is a long-acting antihistamine (H1 histamine antagonist) that is less sedating than older substances of its type.
