COMPOSITIONS AND METHODS FOR INCREASING INSULIN SENSITIVITY
Methods and compositions for treating a blood glucose condition involve identifying a suitable subject and administering an effective amount of a composition that contains one or more of an opioid antagonist, an anticonvulsant, and a psychotherapeutic agent.

12 . The method of claim 1 , wherein the composition comprises a combination of a psychotherapeutic agent and an opioid antagonist.
13 . The method of claim 12 , wherein the psychotherapeutic agent is selected from bupropion, mirtazapine, olanzapine, setiptiline, fluoxetine, and valproate, or a pharmaceutically-acceptable salt or prodrug thereof; and wherein the opioid antagonist is selected from nalmefene, nalorphine, naloxone, naltrexone, and methylnaltrexone, or a pharmaceutically-acceptable salt or prodrug thereof.
