Acebutolol (ABT) is almost absorbed after oral administration, but its bioavailability is reduced because of considerable first-pass metabolism in the gastrointestine and liver. The purpose of this study was to report the pharmacokinetic changes of ABT and its metabolite, diacetolol (DAT) after oral administration of acebutolol to control rabbits and rabbits with mild and severe folate-induced renal failure (FIRRs). Both of the area under the plasma concentration-time curve (AUC^0_∞) of ABT and DAT were significantly increased in mild (p<0.05) and severe FIRRs (p<0.01), but the AUC^0_∞ of DAT was more influenced than that of ABT in severe rabbits. There was a good correlation between serum creatinine and both of AUC^0_∞ of ABT and DAT. The elimination half-life of ABT and DAT was significantly prolonged in mild (p<0.05) and severe (p<0.01) FIRRs, but the half-life of DAT was more influenced than that of ABT in severe FIRRs. The results suggest that the dosage of acebutolol should be adjusted according to the degree of renal disorder on the base of the serum creatinine concentration.
