Depressants exert their effects through a number of different pharmacological mechanisms, the most prominent of which include facilitation of GABA and inhibition of glutamatergic or monoaminergic activity. Other examples are chemicals that modify the electrical signaling inside the body, the most prominent of which are bromides and channel ...
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).

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.
SSRI’s common or very common side effects can include tiredness, anxiety, feeling nervous, dry mouth, dizziness, impaired concentration, fever, memory loss, and sleep disorders.
Most of the adverse effects of Wellbutrin are mild and transient, although a small percentage of people who use this medication experience more severe or longer-lasting side effects. Common side ...
Further, they have fewer and milder side effects. Tricyclic antidepressants also have a higher risk of serious cardiovascular side effects, which SSRIs lack. SSRIs act on signal pathways such as cyclic adenosine monophosphate (cAMP) on the postsynaptic neuronal cell, which leads to the release of brain-derived neurotrophic factor (BDNF). BDNF ...
