Abstract. – OBJECTIVE: Aripiprazole, risperidone, atomoxetine, and methylphenidate are drugs commonly prescribed for many psychiatric conditions and can be used alone or in combination in children and adolescents. This study aimed to investigate comparatively the possible genotoxic effects or genoprotective potentials of these drugs on human lymphocytes and HepG2 cells. MATERIALS AND METHODS: Cytotoxicity analysis was performed with the cell viability test on human lymphocytes and HepG2 cells, and half-maximal inhibitory concentration (IC50) values of the drugs were determined, and three different doses (¼ IC50, ½ IC50, and IC50) were applied for genetic analysis. For the determined doses, cells with and without DNA damage were examined by comet analysis. RESULTS: In lymphocytes, aripiprazole and risperidone increased DNA damage at moderate and maximum doses, whereas atomoxetine increased DNA damage only at the maximum dose. In HepG2 cells, risperidone reduced DNA damage at all doses, while atomoxetine increased DNA damage at all doses. On the other hand, in the DNA-damaged cells induced by hydrogen peroxide (H2O2), DNA damage decreased at all concentrations of all drugs in both lymphocytes and HepG2 cells. CONCLUSIONS: As a result, the genotoxicity of the drugs was found to be dose-dependent, and all drugs showed a genoprotective effect on DNA-damaged cells.
