Abstract

Haloperidol (HLP) is a potent antipsychotic drug that is commonly used for the treatments of schizophrenia and bipolar disorders but has a tendency to cause adverse effects. In the present study, the cyto/genotoxic potential of clinically relevant concentrations of HLP was evaluated in human peripheral blood lymphocytes (HPBLs) as sensitive biomarkers of exposure. HLP was administered as HLP hydrochloride in the final concentrations of 5, 10 and 20 ng/ml for 4 and 24 h period. Cytotoxicity was determined using differential staining of HPBLs with acridine orange and ethidium bromide while chromosomal aberrations, micronucleus and comet assays were applied to estimate the chromosomal and DNA damage after the treatment. The results of the present study indicate that HLP is capable of inducing cyto/genotoxicity in tested cells. Present study has also confirmed the need for further cytogenetic research and regular patient monitoring to minimize the risk of any possible adverse events.Copyright © 2014 Elsevier B.V.
