Serotonin antagonist and reuptake inhibitors (SARIs) are a class of drugs used mainly as antidepressants, but also as anxiolytics and hypnotics. They act by antagonizing serotonin receptors such as 5-HT 2A and inhibiting the reuptake of serotonin, norepinephrine, and/or dopamine. Additionally, most also antagonize α 1-adrenergic receptors.
No difference risk of suicide attempts was detected between SSRIs versus tricyclic antidepressants. [135] A 2006 review suggests that the widespread use of antidepressants in the new "SSRI-era" appears to have led to a highly significant decline in suicide rates in most countries with traditionally high baseline suicide rates.
For example, cocaine, which non-selectively inhibits the reuptake of serotonin, norepinephrine, and dopamine, is an SRI but not an SSRI. SRIs are used predominantly as antidepressants (e.g., SSRIs, SNRIs, and TCAs), though they are also commonly used in the treatment of other psychological conditions such as anxiety disorders and eating disorders.
Other antidepressants include monoamine oxidase inhibitors , serotonin-norepinephrine reuptake inhibitors (SNRIs), atypical antidepressants and tricyclic antidepressants . Lots of acronyms, we know.

A 2006 meta-analysis review found wide variation in the findings of prior studies: for people who had failed to respond to an SSRI antidepressant, between 12% and 86% showed a response to a new drug. However, the more antidepressants an individual had previously tried, the less likely they were to benefit from a new antidepressant trial. [77]
The SSRIs also have less affinity for α 1, α 2, H 1 and muscarinic receptors, which might explain the differences of adverse events between TCAs and SSRIs. [ 6 ] Although SSRIs arrive rapidly to the brain after administration and the effects on 5-HT re-uptake can be measured instantly, it takes about 2–4 weeks to get therapeutic effects ...
