ABSTRACT:
The present invention provides an osmotic device containing controlled release pseudoephedrine in the core in combination with a rapid release H1 antagonist in an external coat. A wide range of H1 antagonist antihistamines, especially fexofenadine, can be used in this device. Particular embodiments of the invention provide osmotic devices having predetermined release profiles. One embodiment of the osmotic device includes an external coat that has been spray coated rather compression coated onto the device. The device with spray coated external core is smaller and easier to swallow than the similar device having a compression coated external coat. The device is useful for the treatment of respiratory congestion related disorders and allergy related disorders. The present devices provide PS and an H1 antagonist according to specific release profiles in combination with specific formulations.
