Abstract: The invention provides oral formulations for the treatment of cold and allergy symptoms. Each formulation combines an antihistamine, an antitussive, and/or a decongestant into one extended release composition. The invention further provides for methods of making and using such formulations, as well as for methods for preventing abuse or extraction of a single drug present in an oral extended release composition comprising two or more of an antihistamine, antitussive, and/or decongestant.

Abstract: The present invention relates to liquid sustained release suspension dosage forms. In particular, the invention encompasses sustained release compositions comprising a dispersed phase, which contains an ion-exchange matrix drug complex, a diffusion controlling membrane coating and a dispersion medium comprising an excipient capable of impeding water activity such that drug dissolution is inhibited prior to administration. Further, the invention provides for compositions wherein several active ingredients associate in a single bead in the dispersed phase, such that the abuse potential of such active ingredients is reduced. The invention also encompasses sustained release formulations of combination drugs comprising an extended release phase and an immediate release phase. The formulations of the invention may be used to treat a variety of conditions and symptoms, including those that require administration of several drugs, such as cold and allergy symptoms.
