Alcohol and histamine metabolic pathways in the body have the common
enzymes aldehyde dehydrogenase and aldehyde oxidase. The metabolite of
ethanol, acetaldehyde, can effectively compete with the metabolites of
histamine, methylimidazole acetaldehyde, and imidazole acetaldehyde. At the
periphery, alcohol and acetaldehyde liberate histamine from its store in
mast cells and depress histamine elimination by inhibiting diamine oxidase,
resulting in elevated histamine levels in tissues. Histamine mediate
alcohol-induced gastric and intestinal damage and bronchial asthma as well
as flushing in Orientals. On the other hand, alcohol provokes food-induced
histaminosis and histamine intolerance, which is an epidemiological
problem. There are many controversial reports concerning the effect of H2
receptor antagonists on ethanol metabolism and the activity of alcohol
dehydrogenase in the stomach. In addition, alcohol affects histamine levels
in the brain by modulating histamine synthesis release, and turnover.
Histamine receptor antagonists can affect ethanol metabolism and change the
sensitivity of animals to the hypnotic effects of alcohol. In contrast to
other neurotransmitters, the involvement of the brain histamine system in
the mechanisms of the central actions of alcohol and in the pathogenesis of
alcoholism is poorly studied and understood.
