Effects of catecholamine agonists and antagonists on alcohol uptake in rats with different stages of experimental alcoholism

Abstract

The effects of various catecholamine agonists and antagonists on 15% ethanol ingestion by outbred albino rats were studied in relation to the stage of experimental alcoholism. In animals with stage I and II alcoholism, alcohol intake was most profoundly inhibited by administration of alpha-adrenoblockers (AA), klofelin, and alpha-methyl-DOPA (AMD), while L-DOPA and cocaine stimulated a significant increase in ethanol ingestion. In stage III alcoholism, both AA and L-DOPA depressed alcohol intake, while AMD and haloperidol had a stimulatory effect. It appears, therefore, that different neurochemical mechanisms are involved in alcohol dependence in different stages of experimental alcoholism in the rat. Furthermore, it seems evident that alpha-adrenergic receptors have a key function in maintaining alcohol dependence. In well-established physical dependence, the importance of the noradrenergic system seems to diminish and dopaminergic mechanisms appear to become predominant. Consequently, in the initial stages of alcoholism, agents which depress the noradrenergic system seem indicated, while at the stage of physical dependence agents which normalize noradrenergic mechanisms and depress dopaminergic mechanisms should be considered. 13 references.
