Drugs administered through different administration routes follow nonlinear elimination. Consider a drug administered through a constant IV infusion, ...
非线性药代动力学:消除半衰期和剂量清除率的依赖性
非线性药代动力学:消除半衰期和剂量清除率的依赖性
Drug elimination half-life and clearance vary with dosage or concentration in nonlinear kinetics. The elimination half-life is influenced by the ...
时间药代动力学: 昼夜节律和对药物反应的影响
时间药代动力学: 昼夜节律和对药物反应的影响
Circadian rhythms influence cyclic changes in plasma drug concentrations through regular fluctuations in physiological functions. Standard circadian ...
时间药代动力学: 时间依赖性药代动力学
时间药代动力学: 时间依赖性药代动力学
Chronopharmacokinetics studies the temporal change in drug absorption and elimination, whether cyclical or noncyclical. Cyclic changes occur over constant ...
非线性药代动力学:生物利用度和蛋白质-药物结合
非线性药代动力学:生物利用度和蛋白质-药物结合
For drugs that follow nonlinear pharmacokinetics, the absorption, distribution, and elimination processes may potentially saturate. A saturable pathway ...
非线性药代动力学:转运蛋白的作用
非线性药代动力学:转运蛋白的作用
