Oxidative injury in schizophrenia can be caused by the disease itself and probably by antipsychotics treatment. The aim of the study was to establish whether there is a difference between ziprasidone, clozapine and haloperidol effect on lipid peroxidation in human plasma, measured by the level of thiobarbituric acid reactive substances (TBARS). The samples of plasma from healthy subjects were incubated with the drugs (1 and 24 h) and compared with control samples. The levels of TBARS were measured spectrophotometrically, according to the Rice-Evans method. The multifactorial variance analysis ANOVA II test showed that the differences in TBARS levels significantly depended on the studied drugs (ziprasidone 40 ng/ml, haloperidol 4 ng/ml and clozapine 350 ng/ml) (F = 3.248 p = 0.047) and (ziprasidone 139 ng/ml, haloperidol 20 ng/ml and clozapine 420 ng/ml) (F = 2.248, p = 2.9 × 10(-5)). Statistically increased levels of TBARS after 24 h incubation of plasma with ziprasidone 139 ng/ml and haloperidol 20 ng/ml (p < 0.001, p < 0.05 respectively) in comparison with control samples were observed. Clozapine did not significantly (p > 0.05) increase TBARS level in plasma in comparison with control samples. The results obtained in the study showed that ziprasidone and haloperidol contrary to clozapine induced a significant increase in plasma lipid peroxidation.
