Evaluation of the hepatic effect of concomitant administration of ciprofloxacin and some antimalarial drugs in Plasmodium berghei infected mice: An in vivo study.

This study evaluated the hepatotoxic effects of artesunate (AS), artemether-lumefantrine (AL) and artesunate-amodiaquine (ASAQ) co-administration with ciprofloxacin (CIP) using animal model. Chloroquine sensitive Plasmodium berghei NK65 strain infected albino mice (120) were utilized for this study, carried out in three phases. Phase 1 comprised eleven groups treated with different doses of either AS, AL, ASAQ or CIP alone. Phase 2 consisted of nine groups treated with 7mg/kg of CIP combined with different doses of AS, AL, ASAQ. Phase 3 comprised ten groups treated with 14mg/kg of CIP (CIP2) with different doses of AS, AL, ASAQ. Seventy-two hours after administration of drugs, toxicity was determined by evaluating the effect of drugs on liver enzymes using spectrophotometer. Statistical analysis revealed that CIP alone significantly (P<0.05) reduced the levels of Aspartate Transaminase (AST) and Serum Alanine Transaminase (ALT) compared to AS, AL and ASAQ alone. Combination of different doses of AS, AL and ASAQ with 7mg/kg CIP significantly increased the level of AST and ALT while combination of AS, AL and ASAQ with 14mg/kg CIP significantly decreased AST and ALT levels. Care should be taken during the co-administration of low dose ciprofloxacin with artesunate, artemether-lumefantrine or artesunate-amodiaquine.
