Farmakokinetikára

Farmakokinetikára, often translated as pharmacokinetics, is the branch of pharmacology that deals with the movement of drugs within the body. It describes what the body does to the drug, encompassing the processes of absorption, distribution, metabolism, and excretion (ADME). Absorption refers to how a drug enters the bloodstream from its site of administration. Distribution describes how the drug spreads throughout the body's tissues and fluids. Metabolism, primarily occurring in the liver, involves the chemical transformation of the drug into different compounds, often making it easier to eliminate. Excretion is the removal of the drug and its metabolites from the body, typically through urine or feces. Understanding pharmacokinetics is crucial for determining appropriate drug dosages, dosing frequencies, and routes of administration to achieve therapeutic effects while minimizing toxicity. Factors such as age, disease state, and interactions with other substances can significantly influence a drug's pharmacokinetic profile. This knowledge allows healthcare professionals to personalize drug therapy for individual patients, optimizing treatment outcomes.
