Mebanazine is an inhibitor of monoamine oxidase. It was introduced in the 1960s for the treatment of depression and was marketed under trade name Actomol. The drug was withdrawn from the market due to hepatotoxicity. In addition to its antidepressant effect, the drug was found to possess an anorexic action and in animal models, it potentiated the hypoglycemic response to insulin and delayed the recovery of blood glucose levels to normal.
