Abstract
Clonidine, guanfacine and tiamenidine, in equihypotensive doses, significantly reduced alcohol intake in ethanol-preferring rats having free choice between 10% ethanol and drinking water. Water intake was only slightly reduced, especially during the first hours following the administration of clonidine. Simultaneous treatment with yohimbine attenuated the clonidine-induced reduction in ethanol intake. Putative central mechanisms underlying the observed inhibitory actions of clonidine and other alpha-2 adrenoceptor agonists on oral self-administration of alcohol are discussed.
