<span class="mw-page-title-main">Monoamine oxidase inhibitor</span> Type of medication

Monoamine oxidase inhibitors (MAOIs) are a class of drugs that inhibit the activity of one or both monoamine oxidase enzymes: monoamine oxidase A (MAO-A) and monoamine oxidase B (MAO-B). They are best known as effective antidepressants, especially for treatment-resistant depression and atypical depression. They are also used to treat panic disorder, social anxiety disorder, Parkinson's disease, and several other disorders.

Tranylcypromine, sold under the brand name Parnate among others, is a monoamine oxidase inhibitor (MAOI). More specifically, tranylcypromine acts as nonselective and irreversible inhibitor of the enzyme monoamine oxidase (MAO). It is used as an antidepressant and anxiolytic agent in the clinical treatment of mood and anxiety disorders, respectively.

Moclobemide, sold under the brand names Amira, Aurorix, Clobemix, Depnil and Manerix among others, is a reversible inhibitor of monoamine oxidase A (RIMA) drug primarily used to treat depression and social anxiety. It is not approved for use in the United States, but is approved in other Western countries such as Canada, the UK and Australia. It is produced by affiliates of the Hoffmann–La Roche pharmaceutical company. Initially, Aurorix was also marketed by Roche in South Africa, but was withdrawn after its patent rights expired and Cipla Medpro's Depnil and Pharma Dynamic's Clorix became available at half the cost.

Bifemelane (INN), or bifemelane hydrochloride (JAN), also known as 4-(O-benzylphenoxy)-N-methylbutylamine, is an antidepressant and cerebral activator that is widely used in the treatment of cerebral infarction patients with depressive symptoms in Japan, and in the treatment of senile dementia as well. It also appears to be useful in the treatment of glaucoma. Bifemelane acts as a monoamine oxidase inhibitor (MAOI) of both isoenzymes, with competitive (reversible) inhibition of MAO-A and non-competitive (irreversible) inhibition of MAO-B, and also acts (weakly) as a norepinephrine reuptake inhibitor. The drug has nootropic, neuroprotective, and antidepressant-like effects in animal models, and appears to enhance the cholinergic system in the brain.

Eprobemide (INN) is a pharmaceutical drug that was used as an antidepressant in Russia. It is a non-competitive reversible inhibitor of monoamine oxidase A that exhibits selective action on serotonin deamination. Eprobemide differs from moclobemide only in the linker that connects the morpholine fragment with the chlorobenzamide — moclobemide has two carbon atoms while eprobemide has three. Its registration was cancelled on December 30, 2003.

<span class="mw-page-title-main">Acetryptine</span> Drug

Acetryptine (INN), also known as 5-acetyltryptamine (5-AT), is a drug described as an antihypertensive agent which was never marketed. Structurally, acetryptine is a substituted tryptamine, and is closely related to other substituted tryptamines like serotonin (5-hydroxytryptamine). It was developed in the early 1960s. The binding of acetryptine to serotonin receptors does not seem to have been well-investigated, although it was assessed at the 5-HT1A and 5-HT1D receptors and found to bind to them with high affinity. The drug may also act as a monoamine oxidase inhibitor (MAOI); specifically, as an inhibitor of MAO-A.
