How does Zoloft (sertraline) work?

Serotonin is a chemical in the human brain that plays an important role in mood regulation. Zoloft is a selective serotonin reuptake inhibitor (SSRI), meaning it prevents the reuptake of serotonin in the brain. By doing so, Zoloft increases the level of serotonin in the brain. This mechanism makes Zoloft very effective in treating mental health conditions such as major depressive disorder and anxiety disorders like obsessive compulsive disorder, post-traumatic stress disorders, panic disorder, and others.
