Cpmin is the minimum concentration achieved during multiple dose administration. Tau is used to represent the dosing interval during multiple dose drug administration. The units are those of time, e.g. hr. A desired tau can be calculated from Cpmin and Cpmax if you know kel. Version B. Briefly describe the term, R, as it is used in the area of multiple dose drug administration.
R is used to represent the fraction of drug remaining at the end of a dosing interval.
Since it is a ratio it has no units. Version D. Briefly describe the superposition principle. To use this method one calculates the concentration from each dose separately and adds these values together to determine the total concentration due to the dosing regimen. Version B. Briefly describe the term induction as it relates to drug metabolism. Most drug metabolism processes involve enzyme reactions.
