Bifemelane (INN), sold under the brand names Alnert and Celeport, is an antidepressant and cerebral activator that was widely used in the treatment of cerebral infarction patients with depressive symptoms in Japan, and in the treatment of dementia as well. It also appears to be useful in the treatment of glaucoma. It has been discontinued in Japan since 1998, when it was removed from the market reportedly for lack of effectiveness.
