[13] [7] [19] [2] It is a selective inhibitor of monoamine oxidase B (MAO-B) at lower doses but additionally inhibits monoamine oxidase A (MAO-A) at higher doses. [ 13 ] [ 7 ] [ 19 ] [ 2 ] MAO-B inhibition is thought to result in increased levels of dopamine and β-phenethylamine , whereas MAO-A inhibition results in increased levels of ...
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 ...
Some MAOIs inhibit both MAO-A and MAO-B equally, other MAOIs have been developed to target one over the other. MAO-A inhibition reduces the breakdown of primarily serotonin, norepinephrine, and dopamine; selective inhibition of MAO-A allows for tyramine to be metabolised via MAO-B. [43] Agents that act on serotonin, if taken with another ...
The pharmacology of antidepressants is not entirely clear.. The earliest and probably most widely accepted scientific theory of antidepressant action is the monoamine hypothesis (which can be traced back to the 1950s), which states that depression is due to an imbalance (most often a deficiency) of the monoamine neurotransmitters (namely serotonin, norepinephrine and dopamine).

Rasagiline acts as an inhibitor of the enzyme monoamine oxidase (MAO) and hence is a monoamine oxidase inhibitor (MAOI). [2] More specifically, it is a selective inhibitor of monoamine oxidase B (MAO-B). [2] The drug is thought to work by increasing levels of the monoamine neurotransmitter dopamine in the brain. [2]
The study, which involved 106 peri- and postmenopausal women and was presented at the Endocrine Society’s annual meeting in May, indicates women should self-monitor their vasomotor symptoms and ...
More severe symptoms include fever, seizures, irregular heartbeat, delirium, and coma. [75] [76] [11] If signs or symptoms arise, discontinue treatment with serotonergic agents immediately. [75] It is recommended to washout 4 to 5 half-lives of the serotonergic agent before using an MAO inhibitor. [77]
