CONTROLLED RELEASE FORMULATIONS OF OPIOID AND NONOPIOID ANALGESICS

摘要

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 a nonopioid analgesic. The nonopioid analgesic is acetaminophen and the opioid analgesic is hydrocodone and pharmaceutically acceptable salts thereof, and 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 19.9ng*hr/mL/mg (per mg hydrocodone bitartrate administered and a Cmax for acetaminophen of between about 2.8 ng/mL/mg and 7.9 ng/mL/mg and AUC for acetaminophen of between about 28.6ng*hr/mL/mg and about 59.1ng*hr/mL/mg (per mg acetaminophen administered) after a single dose.
