Sertraline belongs to selective serotonin reuptake inhibitors (SSRIs), and its main mechanism of action is related to the inhibition of serotonin reuptake in central neurons. By inhibiting the reuptake of serotonin, it enhances the function of serotonin in neural transmission, exerting antidepressant and antianxiety effects.

Sertraline tablets should be taken orally once daily, one tablet (50mg) each time, either in the morning or evening. It can be taken with food or alone.
