Variability in the response to drugs is due to three principal components—the disease, the responsiveness of tissues, and the concentration of the drug at its site of action (as reflected by its plasma concentration). The relative contributions of these components will differ not only for different drugs but also for different effects of the same drug. Rational drug therapy depends on knowledge of all three factors.
