  • Publication number: 20060251721
    Abstract: Sustained release dosage forms for twice daily oral dosing to a human patient for providing relief from pain are provided. The sustained release dosage form comprises an immediate release component and a sustained release component, wherein the immediate release component and the sustained release component collectively contain a therapeutically effective amount of an opioid analgesic and a therapeutically effective amount of nonopioid analgesic. In a preferred embodiment, the nonopioid analgesic is acetaminophen and the opioid analgesic is hydrocodone and pharmaceutically acceptable salts thereof, and in preferred embodiments, the pharmaceutically acceptable salt is bitartrate. The dosage forms produce plasma profiles in a patient characterized by a Cmax for hydrocodone of between about 0.6 ng/mL/mg to about 1.4 ng/mL/mg and an AUC for hydrocodone of between about 9.1 ng*hr/mL/mg to about 19.9 ng*hr/mL/mg (per mg hydrocodone bitartrate administered) and a Cmax for acetaminophen of between about 2.

  • Publication number: 20050089570
    Abstract: A sustained release dosage form is provided comprising a pharmaceutically active agent and pharmaceutically acceptable salts thereof and adapted to release as an erodible solid over a prolonged period of time, wherein the dosage form provides burst release of the pharmaceutically active agent without the use of an immediate release drug coating. The dosage form is able to deliver high doses of poorly soluble or slowly dissolving active agents at a controlled rate. Methods of using the dosage forms to treat disease or conditions in human patients are also disclosed.
