Reversible inhibitor of monoamine oxidase A

Reversible inhibitors of monoamine oxidase A (RIMAs) are a class of drugs which selectively and reversibly inhibit the enzyme monoamine oxidase A (MAO-A). They are used clinically in the treatment of depression and dysthymia, though they have not gained widespread market share in the United States. Because of their reversibility and selectivity, RIMAs are safer than the older monoamine oxidase inhibitors (MAOIs) like phenelzine and tranylcypromine.
