Mechanism of action

Zoloft (sertraline) is a selective serotonin reuptake inhibitor (SSRI) that binds to the serotonin transporter protein and prevents the reabsorption of serotonin from the synaptic cleft back into presynaptic neurons. This increases serotonin concentration in the synapse, enhancing neurotransmission and improving mood regulation. The mechanism is thought to underlie its efficacy in treating depression and anxiety disorders.
