Abstract

The pharmacokinetics of a single 500-mg intramuscular dose of ceftizoxime were studied in 11 healthy adult volunteers and in 22 patients with various degrees of renal dysfunction. The mean serum half-life of ceftizoxime was 1.44 h in normal subjects and 30.2 h in hemodialysis patients. A significant correlation (P less than 0.001) between the elimination rate constant of ceftizoxime and creatinine clearance was demonstrated. The mean urinary recovery in normal subjects was 75.6% within 6 h of dosage; recovery decreased progressively with reduced renal function.

摘要

在11名健康成年志愿者和22名不同程度肾功能不全的患者中研究了单次肌内注射500毫克头孢唑肟的药代动力学。头孢唑肟在正常受试者中的平均血清半衰期为1.44小时,在血液透析患者中为30.2小时。头孢唑肟的消除速率常数与肌酐清除率之间存在显著相关性(P小于0.001)。正常受试者在给药后6小时内的平均尿回收率为75.6%;随着肾功能下降,回收率逐渐降低。
