In cases associated with sudden discontinuation of MAO inhibitors (MAOIs), acute psychosis has been observed. [2] [11] [12] Over fifty symptoms have been reported. [13] The SNRI venlafaxine has been reported to have a higher incidence in withdrawal symptoms after discontinuation when compared to other SNRIs. [14]
Monoamine oxidase inhibitors (MAOIs) have a long and prosperous history as medications for major depressive disorder (MDD). But this type of antidepressant has mostly seen its day. 4 FDA-Approved ...
Many MAOIs irreversibly inhibit monoamine oxidase. It can take at least four weeks for this enzyme to be replaced by the body in the instance of irreversible inhibitors. [ 31 ] With respect to tricyclic antidepressants, only clomipramine and imipramine have a risk of causing SS.
The knowledge of MAOIs began with the serendipitous discovery that iproniazid was a potent MAO inhibitor (MAOI). [45] Originally intended for the treatment of tuberculosis, in 1952, iproniazid's antidepressant properties were discovered when researchers noted that the depressed patients given iproniazid experienced a relief of their depression.
Monoamine oxidase inhibitors, or MAOIs, including phenelzine, isocarboxazid, tranylcypromine, selegiline and others. Other antidepressants, including other SSRIs, SNRIs and tricyclic antidepressants
Selegiline acts as a monoamine oxidase inhibitor (MAOI) and thereby increases levels of monoamine neurotransmitters in the brain. [17] [11] [28] [5] At typical clinical doses used for Parkinson's disease, selegiline is a selective and irreversible inhibitor of monoamine oxidase B (MAO-B), increasing brain levels of dopamine.
[35] [29] However, the pathophysiology of Parkinson's disease is complex and multifacted, and MAO-B inhibitors may only slow the progression of the disease and do not halt it. [35] [29] The MAO-B inhibition by oral selegiline shows dosage dependence at typical therapeutic doses and below (i.e., ≤10 mg/day).
