• Pharmacology

The naphthylamine derivative sertraline is a potent and selective inhibitor of serotonin reuptake into presynaptic terminals and the most widely used that has been shown to have both antidepressant and antianxiety effects. In the present study the possible role of sertraline (acute and chronically doses) was evaluated on lipid peroxidation levels and antioxidant enzyme activities in plasma and brain tissues of (10, 40, 80 mg/kg) sertraline treated Wistar albino rats (n=48). Lipid peroxidation levels (MDA) of plasma and brain tissue increased in all acute and chronic sertraline treated rats (p < 0.05). According to results of present study superoxide dismutase (SOD) levels of brain tissue decreased while plasma levels increased (p < 0.05) as compared with vehicle group. Catalase (CAT) levels of plasma and brain tissue and paraoxonase (PON) levels of plasma decreased (p < 0.05) as compared with vehicle group. Based on the data, it can be concluded that high dose sertraline administration enhances oxidative stress. Therefore, dose adjustment in depression patients seems significant as it may help prevention of further prognosis of the diseases.
