Pseudoephedrine/loratadine (trade names Claritin-D, Clarinase, Clarinase Repetabs, Lorinase) 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".
- 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.
