Work Mechanism & Pharmacology
Patient Overview of Work Mechanism
Sertraline boosts the availability of serotonin, an essential mood-stabilizing brain neurotransmitter, by preventing brain cells from absorbing it too quickly.
Clinical Mechanism of Action (MoA)
Potent, highly selective inhibitor of the presynaptic serotonin reuptake transporter (SERT / SLC6A4). Blocks neuronal serotonin (5-HT) reuptake into presynaptic terminals, augmenting extracellular serotonin concentrations in synaptic clefts across the cerebral cortex and limbic system, leading to downstream 5-HT1A autoreceptor desensitization.
