Effect of Bile juice on the Bioavailability and Pharmacokinetics of Acebutolol in Rabbits

토끼에서 체내담즙이 아세부톨롤의 생체이용률 및 체내동태에 미치는 영향

Abstract

Although acebutolol (ABT) is almost completely absorbed in the gastrointestinal (Gl) tract, oral bioavailability of the drug is low due to extensive first-pass metabolism in the Gl tract and liver. In the present study, bioavailability and pharmacokinetics of ABT was studied in bile duct-bypassed rabbits after oral administration. For ABT the time to reach the plasma peak (T$_{max}$) and mean resident time (MRT) were increased by the treatment. For diacetolol (DAT), a metabolite of ABT area under the plasma concentration-time curve (AUC), T$_{max}$ and plasma half-life were increased by the treatment. These results indicate that oral bioavailability of ABT is associated with the enterohepatic recycling of bile juice components.nts.
