  • Novel compositions and methods for enhancing potency or reducing adverse side effects of opiold agonists
    Publication number: 20090203722
    Abstract: The invention generally relates to novel compositions and methods with an opioid agonist and an opioid antagonist to differentially dose a human subject so as to either enhance analgesic potency without attenuating an adverse side effect of the agonist, or alternatively maintain the analgesic potency of the agonist while attenuating an adverse side effect of the agonist. The invention additionally relates to novel opioid compositions and methods for the gender-based dosing of men and women.

  • Inhibitors of ABC drug transporters at the blood-brain barrier
    Patent number: 7034036
    Abstract: The present invention relates to inhibitors of drug transporters of the ABC protein superfamily, particularly transporters present at the blood brain barrier. ABC transporter inhibitors identified according to the invention increase brain concentrations of CNS-active agents. Such inhibitors increase the influx into the brain and/or reduce the efflux from the brain of such CNS-active agents.

  • Inhibitors of ABC drug transporters in microbial cells
    Publication number: 20040214848
    Abstract: The present invention relates to microbial infections, including those involving multidrug resistance and, in particular, to opioid compounds that are inhibitors of drug transporters of the ABC protein superfamily. The invention relates to methods of treating microbial infections using anti-microbial agents and opioid inhibitors of such transporters. The invention also relates to methods for selecting or identifying compounds for the ability to inhibit drug transporter proteins and to methods of inhibiting drug transporter proteins. The invention concerns the new use of opioid receptor antagonists in the treatment of microbial infections, including multidrug resistant microbial infections.
