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). [1]
In the rest of the body, norepinephrine increases heart rate and blood pressure, triggers the release of glucose from energy stores, increases blood flow to skeletal muscle, reduces blood flow to the gastrointestinal system, and inhibits voiding of the bladder and gastrointestinal motility.
This translates to the 2nd- and 3rd-most-common antidepressants, behind Lexapro (escitalopram), an SSRI. [88] In some studies, SNRIs demonstrated slightly higher antidepressant efficacy than the SSRIs (response rates 63.6% versus 59.3%). [43] However, in one study escitalopram had a superior efficacy profile to venlafaxine. [89]
How long a person takes an antidepressant varies. Some people may need antidepressants for a relatively short period (like while grieving the loss of a loved one), or they might need medication ...
These past discoveries in psychopharmacology led to the development of antidepressants and a range of drugs with different functions on those neurotransmitters. But a new generation of antidepressants were resulted from the discovery of selective serotonin reuptake inhibitors (SSRIs) (e.g., fluoxetine).
Most antidepressants aim for the same target: the monoamine system. They work by raising levels of one or more of the monoamine neurotransmitters in the brain that are involved in mood—serotonin ...
Noradrenergic and specific serotonergic antidepressants (NaSSAs) are a class of psychiatric drugs used primarily as antidepressants. [1] They act by antagonizing the α 2 -adrenergic receptor and certain serotonin receptors such as 5-HT 2A and 5-HT 2C , [ 1 ] but also 5-HT 3 , [ 1 ] 5-HT 6 , and/or 5-HT 7 in some cases.
Since some tricyclic antidepressants (TCAs) and monoamine oxidase inhibitors (MAOIs) can cause harmful interactions if used within 14 days of starting treatment with other antidepressants, you may ...
