Pharmacokinetics and pharmacodynamics are very different in children and adults. For the majority of drugs, in children as well as adults, a relationship exists between pharmacokinetics and pharmacodynamics. The pharmacokinetics of many drugs vary with age (Keams, 1998). For instance, because of the rapid changes in size, body composition, and organ function that occur during the first year of life, clinicians as well as pharmacokineticists and toxicologists are presented with challenges in prescribing safe and effective doses of therapeutic agents (Milsap and Jusko, 1994). Studies with adolescents reveal even more complexity in ding metabolism and differences in drug metabolism between the sexes.
