Abstract

Previously published steady-state equations assumed elimination of total drug. The equations have been derived to cover the case where only free (unbound) drug is eliminated. The equation for oral administration is the same in both cases. The equation for intravenous administration has the same form, but the interpretation of Km is different.

摘要

先前发表的稳态方程假设消除的是总药物。这些方程已推导出来以涵盖仅消除游离(未结合)药物的情况。两种情况下口服给药的方程是相同的。静脉给药的方程形式相同,但对Km的解释不同。
