What is the Origin of Steady-State Levels?

This is a core principle in pharmacokinetics, derived from the concept of a constant, non-changing condition within a dynamic system. The term steady refers to the average concentration remaining stable over multiple dosing intervals. This principle allows clinicians to accurately predict therapeutic efficacy and safety.

What is the Mechanism of Steady-State Levels?

Steady-state is mathematically determined by the half-life of the compound and the dosing interval. It is typically reached after four to five half-lives of the administered substance. Once achieved, the hormone's concentration is sufficient to maintain consistent receptor saturation, ensuring continuous and predictable biological effects on target tissues without excessive peaks or troughs.

Steady-State Levels

Meaning

Steady-State Levels refer to the dynamic equilibrium achieved in the systemic circulation when the rate at which a drug or hormone is introduced into the body precisely matches the rate at which it is eliminated. At this point, the maximum and minimum concentrations fluctuate predictably around a consistent average. Achieving this stable concentration is the clinical goal for most chronic hormonal replacement therapies.
