Pharmacokinetics

Also called PK · ADME · pharmacokinetic profile

Pharmacokinetics (PK) describes what the body does to a drug, summarized as ADME: Absorption, Distribution, Metabolism, and Excretion. Key PK parameters for peptides include bioavailability, volume of distribution, Cmax, Tmax, and elimination half-life. PK shapes dosing frequency and route decisions.
