How does an SSRI work on synapses?

How does an SSRI work on synapses?

SSRIs block the reuptake of serotonin, meaning more serotonin than usual remains available in the synaptic space between the two nerves. This eases the symptoms of depression resulting from the low levels of serotonin.

What happens when serotonin reuptake is inhibited?

Selective serotonin reuptake inhibitors slow the process by which serotonin (a substance that nerves use to send messages to one another) is reused by nerve cells that make it. This increases the amount of serotonin available for stimulating other nerves.

What is the effect of SSRIs serotonin reuptake inhibitors on the concentration of serotonin in the synaptic cleft?

An SSRI overload therefore increases the concentration of serotonin in the synaptic cleft, resulting in inhibition of the negative feedback system of serotonin and thus in symptoms of serotonin syndrome.

How do antidepressants affect the synapse?

Antidepressant drugs inhibit the reuptake of monoamines (such as serotonin, noradrenaline and dopamine) into the presynaptic neuron; persistence of these monoamines in the synaptic cleft results in increased postsynaptic receptor stimulation and hence in increased postsynaptic neurotransmission.
