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.
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.
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.

[97] [90] [214] [84] [85] Differences in effectiveness between different antidepressants are small and not clinically meaningful. [215] [214] The small advantage of antidepressants over placebo is often statistically significant and is the basis for their regulatory approval, but is sufficiently modest that its clinical significance is doubtful.
Escitalopram, a selective serotonin reuptake inhibitor (SSRI) used as an antidepressant.. Reuptake inhibitors (RIs) are a type of reuptake modulators.It is a drug that inhibits the plasmalemmal transporter-mediated reuptake of a neurotransmitter from the synapse into the pre-synaptic neuron.
A serotonin modulator and stimulator (SMS), sometimes referred to more simply as a serotonin modulator, is a type of drug with a multimodal action specific to the serotonin neurotransmitter system.
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. [16]
