Abstract: The preferred exemplary embodiments in the present application provide formulations and methods for the delivery of drugs, particularly drugs of abuse, having an abuse-relevant drug substantially confined in the core and a non-abuse relevant drug in a non-core region. These formulations have reduced potential for abuse. In the formulation, preferably the abuse relevant drug is an opioid and the non-abuse relevant drug is acetaminophen or ibuprofen. More preferably, the opioid is hydrocodone, and the non-abuse relevant analgesic is acetaminophen. In certain preferred embodiments, the dosage forms are characterized by resistance to solvent extraction; tampering, crushing or grinding. Certain embodiments of the inventions provide dosage forms that provide an initial burst of release of drug followed by a prolonged period of controllable drug release.

Abstract: The present invention relates to formulations comprising a solid dispersion product of an active agent having at least one of a hydrogen bond donor moiety (e.g. ibuprofen, fenofibric acid or naproxen) and a proton donor moiety and a pharmaceutically acceptable polyvinyllactam polyvinylacetate poly(alkylene glycol) graft copolymer, and to methods for preparing such formulations.

Abstract: The present invention features solid compositions comprising Compound IA, IB or IC, or a pharmaceutically acceptable salt thereof, in an amorphous form. In one embodiment, Compound IA, IB or IC, or a pharmaceutically acceptable salt thereof, is formulated in an amorphous solid dispersion which comprises a pharmaceutically acceptable hydrophilic polymer and preferably a pharmaceutically acceptable surfactant.
