Angiotensin converting enzyme inhibitors and alcohol abuse.
Angiotensin converting enzyme plays a key role in the regulation of blood pressure and inhibitors of the enzyme are effective antihypertensive agents. An association between hypertension and alcohol abuse has long been recognized and manipulations of the renin-angiotensin system in laboratory animals has been shown to alter their consumption of ethanol. Procedures that decrease the renin-angiotensin system increase ethanol consumption. Paradoxically, inhibitors of angiotensin converting enzyme also diminish drinking. Several possible explanations for this observation have been proposed. However, observations on the relationship between stress-induced drinking and the antidipsogenic action of a fragment of adrenocorticotropic hormone suggest another possibility: angiotensin converting enzyme may be involved in the metabolism of this peptide and thereby exert an influence on drinking behavior.
