Bicarbonate supplementation as a preventive way in statins-induced muscle damage
Abstract
ABSTRACT – Purpose. The aim of this study was to evaluate the bicarbonate-induced improvement of statins, cerivastatin, simvastatin acid and lovastatin acid -induced apoptosis using rat myoblast cell line (L6) as a model of in vitro skeletal muscle and of cerivastatin-induced muscle damage in vivo study. Methods. Statin-induced reduction of cell viability and apoptosis was measured by 3-(4,5-dimethylthiazol-2-yl)2,5-diphenyl tetrazolium bromide (MTT) assay and caspase assay. In vivo, we evaluated plasma creatine phosphokinase (CPK) level in cerivastatin-treated rat. Results. Bicarbonate prevented cerivastatin-, simvastatin- acid and lovastatin acid -induced reduction of cell viability, morphological change and caspase activation in L6 cells. Moreover, in the in vivo study, bicarbonate prevented cerivastatin-induced increase in CPK concentrations. Conclusions. These results from in vitro and in vivo studies support that bicarbonate supplementation prevented statin-induced muscle damage.
