Abstract

Background and Aims: Citalopram is a selective serotonin reuptake inhibitor with a high potency which is occasionally prescribed and used to treat major depression associated with mood disorders as a first-line drug. According to the results of previous studies, evidence of hepatotoxicity related to citalopram treatment were limited and conflicting. Therefore, we aimed to evaluate the hepatotoxicity potential of sub-chronic citalopram administration. Methods: Citalopram was administered to female rats orally in 5 and 10 mg/kg for 30 days. After the exposure period, serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), total and direct bilirubin levels as biomarkers of hepatotoxicity were measured and histopathological examination of liver tissues was performed. Additionally, GSH levels of liver tissues were determined. Results: The risk of hepatotoxicity related to citalopram was shown by significant increases of serum hepatic biomarkers, AST, ALT, and total bilirubin in citalopram-administered groups. According to the histopathological findings, hepatocellular necrosis, hepatic nuclear asymmetry, and disarrangement of hepatic cord cells (hepatocytes) were prominent in the 10 mg/kg citalopram- administered group. On the other hand, there was no significant difference among the groups in terms of GSH levels. Conclusion: The results suggested that the administration of citalopram might cause hepatotoxic effects, depending on the dose.
