  • Publication number: 20170182033
    Abstract: The present disclosure provides extended release pharmaceutical compositions comprising oxycodone and acetaminophen that produce a quick initial onset of analgesia, yet, maintain analgesia for about 12 hours after administration of the composition to a subject in need thereof. The pharmaceutical compositions disclosed herein also reduce the levels of acetaminophen in a subject's blood near the end of the dosing interval because the acetaminophen released by the pharmaceutical composition is being eliminated by a subject's body faster than it is being absorbed.

  • Publication number: 20160250177
    Abstract: The present invention provides compositions for the treatment of cancer. The compositions include liposomes containing a phosphatidylcholine lipid, a sterol, a PEG-lipid, and a taxane. The PEG-lipid constitutes from about 2 to about 8 mol % of the lipids in the liposome. The taxane is docetaxel esterified at the 2?-O position with a heterocyclyl-(C2-5 alkanoic acid). The present invention also provides liposomal compositions for the treatment of cancer comprising administering to a patient in need thereof a liposome, wherein the liposome comprises: a phosphatidylcholine lipid; a sterol; a PEG-lipid; and a taxane or a pharmaceutically acceptable salt thereof; wherein the taxane is docetaxel esterified at the 2?-O-position with a heterocyclyl-(C2-5alkanoic acid); and wherein upon administration of the liposomal composition to the patient, the plasma concentration of docetaxel remain above an efficacy threshold of 0.2 ?M for at least 5 hours.
