Abstract

We report a patient with a parkinsonian syndrome induced by sertraline (Zoloft®), an SSRI antidepressant, whose symptoms resolved after the drug was discontinued. This case prompted us to investigate the effect of sertraline on dopamine metabolism in animals. Sertraline (30 mg/kg, IP) or placebo (vehicle) was administered to two groups of six normal, anesthetized rats and using cerebral microdyalisis extracellular striatal levels of dopamine, the dopamine metabolites (HVA and DOPAC), as well as the serotonin metabolite 5-HIIA were monitored. In animals pre-treated with sertraline, DOPAC, HVA, and 5-HIAA levels were significantly decreased compared to control animals (p < 0.01). These data indicate that sertraline has an effect on dopamine metabolism, which may alter function in the striatum and induce a parkinsonian syndrome.
