Pharmacokinetics

Meaning

Pharmacokinetics, often abbreviated as PK, is the quantitative study of the movement of drugs within the body, encompassing the four critical processes of Absorption, Distribution, Metabolism, and Excretion (ADME). This scientific discipline is essential for determining the appropriate dosage, route of administration, and dosing interval for any therapeutic compound, including hormonal agents. Understanding a drug’s PK profile ensures its concentration at the target site is both safe and therapeutically effective.
