Also provided are methods for use of these combination therapies in potentiating the therapeutic effects of opioid receptor agonists, inhibiting development of acute and/or chronic tolerance to opioid receptor agonists and treating conditions treatable by opioid receptor agonist therapy in a subject. In addition, a method for reversing opioid receptor agonist tolerance and/or restoring therapeutic effect of an opioid receptor agonist in a subject via administration of an alpha-2 receptor antagonist in an amount effective to potentiate, but not antagonize, the therapeutic effect of the opioid receptor agonist is provided.
