Abstract: Lipid peroxidation generates free radicals. These free radicals are scavenged by antioxidant defense mechanisms. An imbalance between the free radicals generation and antioxidant mechanisms can result in tissue damage. Several drugs are known to induce lipid peroxidation which can be responsible for their toxic potential. Hence the current study was planned to assess the effect of ceftriaxone, a third generation cephalosporin, on lipid peroxidation and levels of antioxidants in albino mice. Ceftriaxone was injected intraperitoneally at two doses - 100 mg/kg body weight; 200 mg/kg body weight – to albino mice. TBARS (Thiobarbituric acid reactive substance) levels in plasma, erythrocytes as well as tissue and the antioxidant enzymes activities were estimated. The data from ceftriaxone groups was analyzed with control group using ANOVA and Dunnett’s test as post hoc. Ceftriaxone (100 mg/kg body weight) did not alter TBARS levels compared to control. Ceftriaxone - 200 mg/kg body weight, has significantly increased TBARS levels. The activities of antioxidant enzymes were significantly decreased by ceftriaxone at these doses. The present study demonstrates that ceftriaxone has the potential for lipid peroxidation induction and reduction in the antioxidant enzymes acitivities in albino mice.
