Abstract |
The action of opiate receptor agonists: (D-Ala2)-methionine enkephalinamide (D-MEA), morphine, heroin, etorphine, and antagonists: naloxone and diprenorphine on audiogenic seizures was tested during ethanol abstinence. The action of diazepam and clonidine was also tested Morphine (5 and 20 mg/kg), but not heroin and etorphine, given intraperitoneally inhibited the seizures, similarly as intraventricularly administered D-MEA did. However, morphine given by this route was ineffective. Diazepam and clonidine inhibited audiogenic seizures: the action of clonidine was counteracted by yohimbine, but not by prazosin. The results may be considered as supporting the hypothesis on the participation of opioid system in ethanol abstinence. However, the participation of gabergic and noradrenergic systems cannot be ruled out: these systems may possibly interact with the opioid system in evoking the symptoms of ethanol abstinence.
