腎機能障害例におけるアミノ配糖体の臨床的研究 - HBKの体内動態および血液透析と吸着による除去効果について -

Abstract

In vitro studies of elimination of arbekacin (HBK), a new aminoglycoside antibiotic, from blood by means of hemodialysis or adsorption with charcoal, and pharmacokinetic studies in patients with renal dysfunction were examined. HBK was well eliminated by hollow fiber type artificial kidney (HFAK) with a half-life of 0.13 hr. HBK was also well eliminated by an adsorption tube containing charcoal with even shorter half-life of 0.03 hr. As to pharmacokinetics of HBK in patients with renal dysfunction, blood levels became higher with a greater reduction in 24 hr endogenous creatinine clearance (Ccr). A decreasing tendency was also seen in urinary recovery rate. These results indicated that hemodialysis and adsorption with charcoal are useful for elimination of HBK from blood. It is recommendable in patients with renal dysfunction to take some measures such as prolongation of administration interval of HBK according to the extent of decrease in Ccr.
