Assessment of Potential In Vitro Genotoxic and Cytotoxic Effects of Bupropion Hydrochloride (Wellbutrin) in Human Peripheral Lymphocytes and Human Cortical Neuron
Keywords:Comet assay, genotoxicity, micronucleus, wellbutrin
AbstractIntroduction: Wellbutrin (bupropion hydrochloride; WB), an anti"‘depressant of the aminoketone class is new highly selective norepinephrine and dopamine reuptake inhibitor; it is effective in the treatment of patients with major depression. Materials and Methods: To investigate the in vitro effects of WB in human cultured peripheral blood lymphocytes and human cortical neural (HCN2) cell lines, micronucleus, sister chromatid exchange analysis, cellular viability, and comet assays were employed. The present study is to our knowledge, the first report on WB genotoxicity in cultured human peripheral blood lymphocytes and its cytotoxicity in the HCN2 cell line. We have also investigated the genotoxic potential of WB to induce chromosomal aberrations. Results: WB"‘induced cytotoxicity (measured as reduction of the nuclear division index) possibly prevented the division of damaged cells. Conclusion: We conclude that although, WB exerts potential genotoxic effects in cultured lymphocytes, its cytogenetic effects are very unlikely to occur in blood cultures of WB"‘administered subjects.
