We studied the role of the liver monooxygenase system in pharmacological activity of histochrome, a pharmaceutical form of echinochrome A. In experiments on rats, benzonal, an inductor of the monooxygenase system of phenobarbytal type, significantly potentiated the diuretic effect of histochrome. Benzonal withdrawal was followed by a natriuretic reaction. In view of the known inverse relation between the biological effect of the drug and the rate of its metabolism, our findings suggest that the effects of echinochrome A on some kidney excretory function parameters are produced not by native agent, but one of its metabolites.
