WebIn the field of pharmacokinetics, the area under the curve ( AUC) is the definite integral of the concentration of a drug in blood plasma as a function of time (this can be done using liquid chromatography–mass spectrometry [1] ). In practice, the drug concentration is measured at certain discrete points in time and the trapezoidal rule is ... WebThe process of transferring a drug from the bloodstream to tissues is referred to as distribution. The same principles that govern drug absorption (e.g. ionization of a drug, lipophilicity of a drug, size of a drug, pH of the environment, etc.) also govern the rate and extent that a drug will distribute to various tissues in the body.

WebPharmacokinetics can be simply described as the study of 'what the body does to the drug' and includes: • the rate and extent to which drugs are absorbed into the body and distributed to the body tissues. • the rate and pathways by which drugs are eliminated from the body by metabolism and excretion. • the relationship between time and ... Absorption is the journey of a drug travelling from the site of administration to the site of action. The drug travels by some route of administration (oral, topical-dermal, etc.) in a chosen dosage form (e.g., tablets, capsules, or in solution). Absorption by some other routes, such as intravenous therapy, intramuscular injection, enteral nutrition, is even more straightforward and there is less variability in absorption and bioavailability is often near 100%.
