  • Patent number: 9393192
    Abstract: Dosage forms and methods for providing a substantially ascending rate of release of paliperidone or risperidone are provided. The sustained release dosage forms provide therapeutically effective average steady-state plasma paliperidone or risperidone concentrations when administered once per day. This once-a-day dosing regimen results in only one peak plasma paliperidone or risperidone concentration occurrence in each 24 hour period. In addition, the peak plasma paliperidone or risperidone concentration occurs at a later time following dose administration and exhibits a lesser magnitude than the peak plasma paliperidone or risperidone concentration that occurs following administration of paliperidone or risperidone in an immediate-release dosage form.

  • Publication number: 20140044782
    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.
