关于药动半衰期问题
今天看文献发现用房室模型处理符合二室开放模型，给出t1/2α，t1/2β，在判断线性的时候采用哪个呢？
还有文中又给出一个半衰期和上面都不同，是不是还可以给出一个？




Alpha is half-life for distribution phase. Beta is half-life for the
elimination phase. Gamma for the terminal phases. The useful half-
life is an overall elimination half-life calculated from
noncompartmental pharmacokinetics.
