Selective serotonin reuptake inhibitors (SSRIs) are a class of drugs that are typically used as antidepressants in the treatment of major depressive disorder, anxiety disorders, and other psychological conditions. SSRIs increase the extracellular level of the neurotransmitter serotonin by limiting its reabsorption (reuptake) into the ...
Serotonin. A serotonin reuptake inhibitor (SRI) is a type of drug which acts as a reuptake inhibitor of the neurotransmitter serotonin (5-hydroxytryptamine, or 5-HT) by blocking the action of the serotonin transporter (SERT). This in turn leads to increased extracellular concentrations of serotonin and, therefore, an increase in serotonergic ...
First, serotonin system dysfunction cannot be the sole cause of depression, because not all patients treated with antidepressants show improvement, despite the fact that most patients still show a rapid increase in synaptic serotonin. Second, if significant mood improvements do occur, this is often not for at least two to four weeks.

In fact, when the former antidepressants build up in the bloodstream and the serotonin level is increased, it is common for the patient to feel worse ...
A serotonin pathway identifies aggregate projections from neurons which synthesize and communicate the monoamine neurotransmitter serotonin. [ citation needed ] These pathways are relevant to different psychiatric and neurological disorders.
