Hepatic; may involve CYP2C19 and CYP2D6; extensive first pass metabolism; forms metabolite N-desmethylsertraline (APA [Gelenberg 2010]); Note: Children 6 to 17 years may metabolize sertraline slightly better than adults, as pediatric AUCs and peak concentrations were 22% lower than adults when adjusted for weight; however, lower doses are recommended for younger pediatric patients to avoid excessive drug levels) Urine (40% to 45% as metabolites); feces (40% to 45%; 12% to 14% as unchanged drug) Depression: The onset of action is within a week, however, individual response varies greatly and full response may not be seen until 8 to 12 weeks after initiation of treatment (APA [Gelenberg 2010]).

    Sertraline is used for a number of conditions, including major depressive disorder (MDD), obsessive–compulsive disorder (OCD), body dysmorphic disorder (BDD), posttraumatic stress disorder (PTSD), premenstrual dysphoric disorder (PMDD), panic disorder, and social anxiety disorder (SAD). The comparative efficacy of sertraline and TCAs for melancholic depression has not been studied. A 1998 review suggested that, due to its pharmacology, sertraline may be more efficacious than other SSRIs and equal to TCAs for the treatment of melancholic depression. A meta-analysis of 12 new-generation antidepressants showed that sertraline and escitalopram are the best in terms of efficacy and acceptability in the acute-phase treatment of adults with unipolar MDD. Sertraline used for the treatment of depression in elderly (older than 60) patients was superior to placebo and comparable to another SSRI fluoxetine, and TCAs amitriptyline, nortriptyline (Pamelor) and imipramine. Sertraline had much lower rates of adverse effects than these TCAs, with the exception of nausea, which occurred more frequently with sertraline. In addition, sertraline appeared to be more effective than fluoxetine or nortriptyline in the older-than-70 subgroup. placebo in elderly patients showed a statistically significant (that is, unlikely to occur by chance), but clinically very modest improvement in depression and no improvement in quality of life. A meta-analysis on SSRIs and SNRIs that look at partial response (defined as at least a 50% reduction in depression score from baseline) found that sertraline, paroxetine and duloxetine were better than placebo. Studies have shown that sertraline has no significant affinity for adrenergic (alpha1, alpha2, beta), cholinergic, GABA, dopaminergic, histaminergic, serotonergic (5HT1A, 5HT1B, 5HT2), or benzodiazepine receptors. The chronic administration of sertraline was found in animals to down regulate brain norepinephrine receptors. The effect of sertraline on the QTc interval was evaluated in a randomized, double-blind, placebo- and positive-controlled three-period crossover thorough QTc study in 54 healthy adult subjects. At 2-fold the maximum recommended daily dose (~3-fold the steady-state exposure for sertraline and N-desmethylsertraline), the largest mean ΔΔQTc was 10 ms with upper bound of two-sided 90% confidence interval of 12 ms. The length of the QTc interval was also positively correlated with serum concentrations of sertraline and N- desmethylsertraline concentrations. These concentration-based analyses, however, indicated a lesser effect on QTc at maximally observed concentration than in the primary analysis ) of sertraline occurred between 4.5 to 8.4 hours post-dosing. The average terminal elimination half-life of plasma sertraline is about 26 hours. Consistent with the terminal elimination half-life, there is an approximately two-fold accumulation up to steady-state concentrations, which are achieved after one week of once-daily dosing.
