Pharmacokinetics (PK)

Pharmacokinetics (PK) refers to the study of how a drug moves through the body over time. It involves the processes of absorption, distribution, metabolism, and excretion of a drug. PK studies are typically conducted in Phase I trials, where healthy volunteers or patients receive the drug to assess its safety and metabolism. The data collected helps guide dose selection for later phases of clinical trials, ensuring both efficacy and safety in larger patient populations.
