Selective serotonin reuptake inhibitors (SSRIs) are primarily utilized in the treatment of depression. They function by increasing the levels of serotonin in the brain, which is a neurotransmitter linked to mood regulation. By inhibiting the reuptake of serotonin, these medications enhance mood and alleviate symptoms associated with depressive disorders.

In addition to treating depression, SSRIs can also be prescribed for conditions such as anxiety disorders, obsessive-compulsive disorder, and some other mood disorders, but their primary indication remains major depressive disorder. Understanding the mechanism of action and the role of serotonin in mood regulation highlights why SSRIs are specifically effective for depression.
