A patient with rheumatoid arthritis developed rhabdomyolysis while undergoing treatment with mizoribine concomitantly with bezafibrate. The symptoms rapidly disappeared and laboratory test results normalized when she discontinued the two drugs. The purpose of the present study was to elucidate the transporter-mediated molecular pharmacokinetic mechanisms of drug-drug interactions between bezafibrate and mizoribine. Comparing bezafibrate-mizoribine group with bezafibrate group, the Tmax and Cmax of bezafibrate were essentially unchanged in rats. The AUC of bezafibrate was significantly increased and t1/2ß was prolonged markedly with an obviously reduction in plasma clearance and cumulative urinary excretion. The changes were similar to oral studies following intravenous co-administration. In rat kidney slices, the uptake of bezafibrate was markedly inhibited by p-aminohippurate, benzylpenicillin and probenecid but not by tetraethyl ammonium. Mizoribine not only decreased the uptake of bezafibrate, but also inhibited the uptake of p-aminohippurate and benzylpenicillin. The uptakes of bezafibrate and mizoribine were significantly higher compared to vector-HEK293 cells. The uptakes of bezafibrate and mizoribine in highest concentration were increased 1.63 and 1.46 folds in hOAT1-transfected cells, 1.43 and 1.24 folds in hOAT3-transfected cells, respectively. The Km values of bezafibrate uptake by hOAT1/3hOAT1-/hOAT3-HEK293 K293 cells were increased 1.68 fold in hOAT1-HEK293 cell and 2.12 fold in hOAT3-HEK293 cell in the presence of mizoribine with no change of Vmax. It indicated that mizoribine could inhibit the uptake of bezafibrate by hOAT1/3-HEK293 cells in a competitive way. In conclusion, OAT1 and OAT3 are the target transporters of drug-drug interactions between bezafibrate and mizoribine in pharmacokinetic aspects.
