What is the Meaning of Pharmacokinetics?

Pharmacokinetics (PK) quantifies the time course of a substance—such as a hormone or therapeutic agent—as it undergoes Absorption, Distribution, Metabolism, and Excretion (ADME) within the body. Understanding PK is essential for determining appropriate dosing schedules to maintain therapeutic concentrations at target sites. It provides the framework for understanding drug exposure.

What is the Origin of Pharmacokinetics?

Derived from Greek roots meaning 'drug' and 'to move,' PK describes the fate and movement of exogenous compounds through biological compartments.

What is the Mechanism of Pharmacokinetics?

The process is modeled mathematically based on physiological parameters like clearance rates and volume of distribution. For hormones, PK dictates how quickly they are cleared or bound to transport proteins, influencing their effective half-life and overall systemic availability for receptor interaction.
