WebA drug’s clearance and the volume of distribution determine its half-life. The concept of half-life and its relevant equations are discussed in Lesson 3. Clearance (expressed as volume/time) describes the removal of drug from a volume of plasma in a given unit of time (drug loss from the body). Clearance does not indicate the amount WebThe Elimination Half-life is a derived pharmacokinetic parameter dependent on Clearance and Volume of Distribution (Vd). 0.693 * Vd Half-life = ----- Clearance The above graph is based on a drug with a 12 hour half-life. Change the Clearance and Vd using the sliders provided and see how the half-life changes.
