farmacocinetic

Pharmacokinetics describes the movement of drugs within the body. It encompasses the processes of absorption, distribution, metabolism, and excretion, often abbreviated as ADME. Absorption refers to how a drug enters the bloodstream from its site of administration. Distribution describes how a drug travels throughout the body's tissues and fluids. Metabolism, also known as biotransformation, is the chemical alteration of a drug by the body, usually by enzymes, to make it easier to eliminate. Excretion is the removal of the drug and its metabolites from the body, typically via the kidneys or liver. Understanding pharmacokinetics is crucial for determining appropriate drug dosages, dosing intervals, and routes of administration to achieve therapeutic effects while minimizing adverse reactions. Factors such as age, disease state, and genetic makeup can influence a drug's pharmacokinetic profile.
