Since an SSRI blocks the normal reuptake of serotonin from the synaptic cleft, the neurotransmitter stays in this extracellular space longer than normal, and in response, the brain’s synthesis of serotonin dramatically decreases. As a result, serotonin levels in brain tissues end up markedly depleted.
Do antidepressants decrease serotonin?
SSRIs treat depression by increasing levels of serotonin in the brain. Serotonin is one of the chemical messengers (neurotransmitters) that carry signals between brain nerve cells (neurons). SSRIs block the reabsorption (reuptake) of serotonin into neurons.
