本文提出一个分析药物吸收动力学的方法。它的数学推导简单且易推广到多室模型;其计算量比Loo-Riegelman法及其简化法都少,且因不含指数函数而完全适合手算;其计算结果与L-R法基本相同。 This article presents a method for analyzing drug absorption kinetics. Its mathematical derivation is simple and easy to generalize to the multi-compartment model. Its computational complexity is less than that of the Loo-Riegelman method and its simplification method, and it is completely suitable for hand calculations because it does not contain an exponential function. The calculation results are basically the same as those of the L-R method.
