Abstract:
The present invention relates to compositions for oral administration. The invention preferably comprises at least one abuse - resistant drug delivery composition for delivering a drug having potential for dose dumping in alcohol, related methods of preparing these dosage forms, and methods of treating a patient in need thereof comprising administering the inventive compositions to the patient. The dosage form can include verapamil. These formulations have reduced potential for abuse. In another 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 features solid pharmaceutical dosage formulations comprising ritonavir. As a non-limiting example, a dosage form of the present invention comprises a solid dispersion or solid solution of ritonavir in a matrix, where the matrix comprises at least one water-soluble polymer, such as copovidone, and at least one surfactant, such as polyoxyl 40 hydrogenated castor oil or macrogolglycerol hydroxystearate. Preferably, the solid dispersion or solution does not include, or includes only an insignificant amount of, PEG.
