Piperacillin, ticarcillin, and carbenicillin were administered intravenously to 10 healthy volunteers in a three-way, crossover study. The pharmacokinetics of the three drugs were in general quite similar. The peak serum concentration of piperacillin achieved at the end of a 30-min intravenous infusion was 63.5 +/- 27.6 microgram/ml. During the first 8 h, 67.5% of the dose of piperacillin was excreted in the urine, and the urinary concentration was extremely high. All three penicillins had high volumes of distribution. The serum half-life of the beta elimination phase of carbenicillin was lower than that of either piperacillin or ticarcillin. The volunteers experienced no adverse reactions from the administration of the drugs.
在一项三交叉研究中,对10名健康志愿者静脉注射哌拉西林、替卡西林和羧苄西林。这三种药物的药代动力学总体上非常相似。静脉输注30分钟结束时,哌拉西林的血清峰值浓度为63.5±27.6微克/毫升。在最初8小时内,哌拉西林剂量的67.5%经尿液排泄,且尿液浓度极高。所有三种青霉素的分布容积都很大。羧苄西林β消除相的血清半衰期低于哌拉西林或替卡西林。志愿者在用药过程中未出现不良反应。
