Nialamide is a nonselective monoamine oxidase (MAO) inhibitor that is used as an antidepressant.
World Health Organization (WHO)
Nialamide, a monoamine oxidase inhibitor (MAOI), was
introduced in 1959 for the treatment of depressive illness. Subsequently concern
regarding potentially serious interactions between MAOIs and foods containing
tyramine inspired much restrictive regulatory action. However, MAOIs still retain a
place in the treatment of serious depressive illness although there is no
international consensus on which compounds should be preferred. Thus nialamide
remains available in several countries.
