Sertraline hydrochloride (trade names Zoloft, Lustral) is an antidepressant of the selective serotonin reuptake inhibitor (SSRI) class. It was introduced to the market by Pfizer in 1991. Sertraline is primarily used to treat major depressive disorder in adult outpatients as well as obsessivecompulsive, panic, and social anxiety disorders in both adults and children. In 2011, it was the second-most prescribed antidepressant on the U.S. retail market, with 37,208,000 prescriptions. The efficacy of sertraline for depression is similar to that of older tricyclic antidepressants, but its side effects are much less pronounced. Differences with newer antidepressants are subtler and also mostly confined to side effects. Evidence suggests that sertraline may work better than fluoxetine (Prozac) for some subtypes of depression.
