AB  - Atypical antipsychotic drugs (APDs) are being used to treat
acute psychotic episodes in schizophrenia and schizophrenia-related
diseases as well as a variety of nonpsychotic disorders.
Despite their effectiveness, we showed that APDs clozapine
(CLO), ziprasidone (ZIP) and sertindole (SER) increased oxidative
stress and reduced antioxidative defence capacity in rat kidneys
and heart. Given the scarcity of data about CLO, ZIP and
SER actions on the brain redox homeostasis, the goal of current
study was to investigate their impact on antioxidant enzymes:
total superoxide dismutase (SOD), catalase (CAT), glutathione
peroxidase (GPx) and glutathione reductase (GR) in brain of 3 month old male Wistar rats treated daily via intubation with
water (control group), CLO (45 mg/kg/day), ZIP (20 mg/kg/day)
or SER (2.5 mg/kg/day) for 6 weeks. There were no significant
changes in investigated parameters in CLO and ZIP groups.
However, in SER group the total SOD activity was decreased
while CAT and GPx activities were increased compared to control
group (One-way ANOVA with Tukey’s HSD test, P < 0.05).
Since both CAT and GPx catalyze decomposition of H2O2, their
increased activity in SER group suggests an elevated peroxide
pressure. This conclusion can be strengthened since the activity
of SOD can be decreased by elevated concentration of H2O2.
Our results suggest that SER could cause a redox imbalance in
brain with possible negative effects on mitochondrial respiration
and neural tissue metabolism. *The authors marked with an
