Sertraline: a new antidepressant

Sertraline is a serotonin reuptake inhibitor that has been approved for use in the treatment of depression. Its side-effect profile is similar to that of fluoxetine, a drug of the same class. The side effects of these drugs most often affect the gastrointestinal tract. Serotonin reuptake inhibitors are nonsedating and free of cardiac effects; they do not cause hypotension, urinary retention or blurred vision. Sertraline, like fluoxetine, appears to be safer than tricyclic antidepressants in overdose. However, no clinical studies comparing sertraline and fluoxetine have been published. The wholesale cost of a month's supply of sertraline is about $50, compared with about $5 for a generic tricyclic antidepressant. Despite their cost, serotonin uptake inhibitors may be the initial drugs of choice in depressed elderly patients, because these patients are at increased risk for suicide and have a low tolerance for the side effects of tricyclic antidepressants.
