中文简介: | Saltzman教授首先介绍了药代动力学和药效学。索尔兹曼教授谈到了剂量反应的概念。他介绍了不同的给药途径以及它们如何影响药物分布和生物利用度(即静脉、口服和舌下给药途径)。肝脏的首过药物代谢也是药物降解的重要来源。最后,Saltzman教授将人体建模为一个搅拌良好的容器,解释了一阶速率方程:C=(M0/V)*e-kt,可用于计算体内药物的量(M),作为时间(t)和速率常数(k)的函数;药物半衰期方程为:t=ln(2/k)。 |
课程简介: | Professor Saltzman starts the lecture with an introduction to pharmacokinetics and pharmacodynamics. Professor Saltzman talks about the concept of dose-response. He introduces different routes of drug administration and how they affect drug distribution and bioavailability (i.e., intravenous, oral, and sublingual routes). First-pass drug metabolism by the liver is also identified as an important source of drug degradation. Finally, modeling the body as a well-stirred vessel, Professor Saltzman explains the first-order rate equation: C = (M0/V)*e-kt, that can be used calculate the amount of drug in the body (M) as a function of time (t) and a rate constant (k); and the equation for drug half-life: t = ln(2/k). |
关 键 词: | 药代动力学; 药效学; 剂量反应 |
