Genotoxicity of ibuprofen in mouse bone marrow cells in vivo

Abstract

Genotoxicity of ibuprofen was evaluated by employing the mouse in vivo chromosomal aberration (CA) test. Ibuprofen administered orally at doses of 10, 20, 40, and 60mg/kg body weight to mice resulted in mitotic depression and induction of CAs. A dose-related decrease in mitotic index (MI) and an increase in the frequencies of chromosomal aberrations per cell (CAs/cell) were recorded in bone marrow cells. However, a statistically significant reduction in MI and an increase in CAs/cell were found for both the higher doses. The results obtained indicate that ibuprofen is capable of inducing dose-dependent genotoxicity in bone marrow cells of mice. © 2012 Informa Healthcare USA, Inc.
