WebOther factors are related to individual physiology. The effects of some individual factors (eg, renal failure, obesity, hepatic failure, dehydration) can be reasonably predicted, but other factors are idiosyncratic and thus have unpredictable effects. WebDec 16, 2003 · Since the effect of age on drug sensitivities varies with the drug studied and the response measured, generalizations are often difficult. Studies of drug sensitivity require measurement of concentrations of drug in plasma as differences in pharmacokinetics with increasing age may increase or decrease differences in response to the drug.
