Abstract
The present invention provides an osmotic device containing controlled release diltiazem in the core in combination with a rapid release ACE inhibitor, or diuretic, in an external coat. The delivery device of the invention can also be a chronotherapeutic osmotic device that provides a delayed and controlled release of diltiazem and a delay and rapid release of an ACE inhibitor or diuretic. A wide range of ACE inhibitors or diuretics can be used in this device. Particular embodiments of the invention provide osmotic devices having predetermined release profiles. One specific embodiment of the osmotic device includes an external coat that has been spray coated rather than 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 blood pressure or hypertension related disorders.
