WebThe maximum concentration of a drug in blood plasma represents a drug’s peak effect. Cmax is one of the primary pharmacokinetic measures for evaluating how the body acts … 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 ...

WebPeak time (when maximum plasma drug concentration occurs) is the most widely used general index of absorption rate; the slower the absorption, the later the peak time. For drugs excreted primarily unchanged in urine, bioavailability can be estimated by … Pharmacokinetics, sometimes described as what the body does to a drug, refers to …
WebDec 12, 2024 · The peak plasma drug concentration is the maximum drug concentration in plasma after administration of a drugs. It is crucial for assessing the safety of drug. Additionally, it reflects the drug’s toxicity level in the body.
