  • Publication number: 20090131334
    Abstract: The invention describes compounds, compositions, and methods of using the same comprising a chemical moiety covalently attached to amphetamine. These compounds and compositions are useful for reducing or preventing abuse and overdose of amphetamine. These compounds and compositions find particular use in providing an abuse-resistant alternative treatment for certain disorders, such as attention deficit hyperactivity disorder (ADHD), ADD, narcolepsy, and obesity. Oral bioavailability of amphetamine is maintained at therapeutically useful doses. At higher doses bioavailability is substantially reduced, thereby providing a method of reducing oral abuse liability. Further, compounds and compositions of the invention decrease the bioavailability of amphetamine by parenteral routes, such as intravenous or intranasal administration, further limiting their abuse liability.

  • Patent number: 7375082
    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.

  • Patent number: 7375083
    Abstract: The invention relates to pharmaceutical compositions comprised of a chemical moiety attached to an active agent in a manner that substantially decreases the potential of the active agent to cause overdose or to be abused. When delivered at the proper dosage the pharmaceutical composition provides therapeutic activity similar to that of the parent active agent.

  • Publication number: 20070203055
    Abstract: The invention relates to pharmaceutical compounds and compositions comprised of a chemical moiety attached to an opioid such as oxycodone in a manner that substantially decreases the potential of the opioid to cause overdose. When delivered at the proper dosage the pharmaceutical composition provides therapeutic activity similar to that of the parent active agent. Further the compounds and compositions of the invention are useful in preventing addiction and susceptibility to addiction.
