Regulation of feeding behavior, with special reference to histamine.

Treatment with psychotropic or antiallergic drugs which block histamine H1-receptors is known to be connected with weight gain. Also in experimental animals food intake is changed after manipulation of the histaminergic system, food intake may be decreased by various treatments with increase histaminergic activity and increased if histaminergic activity is reduced. Recent studies are reviewed illustrating the potential role of brain histaminergic system in the fascinating and complicated regulation of feeding.
