摘要
本文报道7例健康青年志愿者口服50mg丙咪嗪的药代动力学参数。丙咪嗪药时曲线符合二室线性动力学。其V/F(c)=1088±157 1;t1/2β=28.6±11.5h;t1/2Ka=0.688±0.280h;CL(s)=70.56±18.90 l/h。主要代谢产物去甲丙咪嗪药时曲线符合一室线性动力学。其t1/2=44.5±33.9h;t1/2Ka=2.01±1.60h;CL(s)=16O±118 l/h。统计学处理表明,去甲丙咪嗪的达峰时间较丙咪嗪显著延迟,其t1/2Ka相应延长,峰浓度亦低于原型药物。本文讨论了代谢产物药代动力学参数的临床意义。
Pharmacokinetic parameters of imipramine were studied onseven healthy young adult volunteers. The concentration-time curve ofimipramine fitted in with a two-compartment kinetic model. The parametersof it were as follows: V/F(c)=1088±1570 l; t1/2β=28.6±11.5h; t1/2Ka=0.69±0.28 h; CL(s)=70.6±18.9l/h. The concentration-time curve of desi-pramine, the major metabolite of imipramine, fitted in with a one-compar-tment kinetic model. The parameters of it were as follows: t1/2Ke=44.5±33.9h; t1/2Ka=2.01±1.60h; CL=160±118 l/h. It was discovered in statisticalanalysis that the T_(peak) of desipramine was significantly longer than thatof imipramine; the t1/2Ka of it was correspondingly longer and the C_(max) ofdesipramine was lower too. The t1/2β of it was longer than that of the parentdrug. The clinical significance of the pharmacokinetics of the metabolitewas discussed.
