From the first page of the chapter:

Objectives Upon completion of this chapter, you will have the ability to:

 • calculate plasma drug concentration at any given time after the administration of an extravascular dose of a drug, based on known or estimated pharmacokinetic parameters

• interpret the plasma drug concentration versus time curve of a drug administered extravascularly as the sum of an absorption curve and an elimination curve

 • employ extrapolation techniques to characterize the absorption phase

• calculate the absorption rate constant and explain factors that influence this constant

• explain possible reasons for the presence of lag time in a drug’s absorption

• calculate peak plasma drug concentration, (Cp)max, and the time, tmax, at which this occurs

• explain the factors that influence peak plasma concentration and peak time

• decide when flip-flop kinetics may be a factor in the plasma drug concentration versus time curve of a drug administered extravascularly.

This provides an excellent step-by-step of the physiology, construction of model, and notions like peak concentration as well as issues like lag time.
