Medications generally interact with a specific target in the body, this interaction enhances, suppresses, or changes the function of the target and thus produces an effect. Receptor number and responsiveness also declines with age, however, this does not necessarily change drug sensitivity or effectiveness. (1987). Expert Opin.

Pharmacodynamics includes both the desired effect of the drug as well as the undesired, or side, effects. They found that elderly patients (mean: 68.5years) had higher dose-normalized tacrolimus trough concentrations than younger adults (Jacobson et al., 2012).

To date, no studies in adult recipients have reported patient age to be a significant covariate in its own right, however several studies have found that patient factors which can change with age (e.g. 29, 231236. Wu, C., Evans, I., Joseph, R., Shapiro, R., Tan, H., et al. Take a Quiz! Albright, J. F., and Albright, J. W. (2003). The intricate balance between under- and over-immunosuppression is increasingly complex in this cohort, due to changes in drug pharmacokinetics and pharmacodynamics (Boesmueller et al., 2011; Krenzien et al., 2015; Karpe et al., 2017).
