Abstract: The present invention decreases the potential for abuse of opioids, particularly hydrocodone, by covalent modification. The invention provides methods of delivering hydrocodone as conjugates that release the hydrocodone following oral administration while being resistant to abuse by circuitous routes such as intravenous (“shooting”) injection and intranasal administration (“snorting”). Further, hydrocodone compositions of the invention are resistant to oral abuse as well, since release of the hydrocodone at suprapharmacological doses reaches saturation.

Abstract: The invention relates to compounds, compositions and methods comprised of a chemical moiety attached to hydrocodone. The invention provides embodiments that provide a decrease in the potential of hydrocodone to cause overdose or to be abused while still delivering therapeutic activity similar to that of the parent hydrocodone. The invention also provides methods of delivering hydrocodone as conjugates that release the hydrocodone following oral administration while being resistant to abuse by other routes such as intravenous injection (“shooting”) and intranasal administration (“snorting”). Further, hydrocodone compositions of the invention are resistant to oral abuse as well, since release of the hydrocodone at suprapharmacological doses reaches saturation.
Abstract: A multiple pulsed dose drug delivery system for pharmaceutically active amphetamine salts, comprising a pharmaceutically active amphetamine salt covered with an immediate-release coating and a pharmaceutically active amphetamine salt covered with an enteric coating wherein the immediate release coating and the enteric coating provide for multiple pulsed dose delivery of the pharmaceutically active amphetamine salt. The product can be composed of either one or a number of beads in a dosage form, including either capsule, tablet, or sachet method for administering the beads.
