The nurse understands that several physiologic changes are related to normal aging. Absorption change is the least affected by the pharmacokinetic process during aging.
Pharmacokinetics, sometimes abbreviated as PK, could be a branch of pharmacology dedicated to determining the fate of gear administered to a living organism.
The substances of interest include any chemical xenobiotic such as: pharmaceutical drugs, pesticides, food additives, cosmetics, etc.
Think of pharmacokinetics as a drug's journey through the body, during which it passes through four different phases: absorption, distribution, metabolism, and excretion.
The most important principle in pharmacokinetics theory is drug absorption which is defined because the transportation of the unmetabolized drug from the location of administration to the body circulation system. Several factors can effect the absorption of a drug into the body. These include physicochemical properties.
