Because there is a directly proportionate relationship between administered drug dose and steady-state plasma level, Equations2.2 and 2.3provide a straightforward guide to dose adjustment for drugs that are eliminated by first-order kinetics. Thus, to double the plasma level, the dose simply should ...
and radioactivity units. Among the topics covered in this chapter are the definition and measurement of radionuclide half-life and the derivation and application of the equations defining radionuclide decay and half-life. These equations include the decay of a radionuclide to a stable daughter nuclide...
