To attain this goal, enough concentrations of the medicine must be delivered to the target tissues so that therapeutic, yet nontoxic levels are obtained (Van den Anker, et al., 2018). The interaction of a drug molecule with a receptor leads to the initiation of a sequence of molecular events, resulting in pharmacodynamics or pharmacologic response. Pharmacodynamics is the study of how medicines act on living organisms while pharmacokinetics influences the chosen route of administration for a given medication, the quantity and frequency of each dose, and its dosing intervals (Sera & McPherson, 2012). A lot of studies have been conducted regarding the impact of maturation on developmental changes in pharmacokinetics. Contrarily, there is little information about how human growth and development and their intersection with illness impact pharmacodynamics (Van den Anker, et al., 2018). With pediatric therapeutics, it is commonly presumed that achievement of systematic drug exposure in a child or infant comparable to that seen in adults, which is linked to a desired
