Effect of Sertraline on Plasma Nortriptyline Levels in Depressed Elderly

Abstract

Overall, a modest effect of sertraline was observed on nortriptyline metabolism in these elderly depressed patients. This is consistent with prior reports of a weak inhibition of CYP2D6 by sertraline in vitro and in young healthy volunteers. However, some patients showed a change in plasma nortriptyline level that would be considered clinically significant. Thus, careful monitoring of plasma nortriptyline levels is recommended in all patients treated with a combination of nortriptyline and sertraline.
