title: An attempted reversal of cocaine-induced analgesia by dexamethasone.
abstract: Analgesia produced by systemic cocaine (20 mg/kg intraperitoneally) was not attenuated by dexamethasone (0.25-2.5 mg/kg) in the formalin or tail pinch test in rats. The result suggests that the activation of the corticotropin releasing factor-adrenocorticotropin/beta-endorphin axis does not explain cocaine-induced analgesia.
