1.在7例原位肝移植患者中,首次口服FK 506(0.04 +/- 0.02 mg kg-1)作为主要免疫抑制剂后,测定了大环内酯类免疫抑制剂FK 506及其代谢产物的血液和尿液浓度。一个特定的hpl c使用MS测定法,允许测量母体药物和8种代谢产物。结果进行了比较,使用微粒子酶免疫测定法(MEIA)。2.通过一级吸收的开放二室模型描述血药浓度,得到以下平均数据:tmax:1.9(h),Cmax:17.4(μ g l-1),AUC:328.1(μ g l-1 h),t1/2,1:0.74(h)。终末消除半衰期估计约为26 h,使用h.p.l.c.- MS分析。3.血液中发现的代谢物是去甲基-FK 506和去甲基-羟基-FK 506,而在尿液中检测到FK 506及其八种代谢物。
1. Blood and urine concentrations of the macrolide immunosuppressant FK506 and its metabolites were measured in seven orthotopic liver transplant patients after the first oral dose of FK506 (0.04 +/- 0.02 mg kg-1) used as primary immunosuppressant. A specific h.p.l.c.-MS assay was used, allowing the measurement of parent drug and eight metabolites. Results were compared with those obtained using a microparticle enzyme immunoassay (MEIA). 2. Blood drug concentrations were described by an open two compartment model with first-order absorption giving the following mean data: tmax: 1.9 (h), Cmax: 17.4 (microgram l-1), AUC: 328.1 (microgram l-1 h), t1/2,1: 0.74 (h). The terminal elimination half-life was estimated at about 26 h using the h.p.l.c.-MS assay. 3. The metabolites found in blood were demethyl-FK506 and demethyl-hydroxy-FK506, while in urine FK506 and eight of its metabolites were detected.
