What is the Origin of Systemic Hormone Kinetics?

This is a term derived from pharmacokinetics and applied to the field of endocrinology, recognizing that the steady-state concentration of a hormone is the result of a dynamic equilibrium. Understanding kinetics is essential for precise dosing and timing in hormone replacement therapy.

What is the Mechanism of Systemic Hormone Kinetics?

The mechanism involves analyzing the half-life and metabolic clearance rate of hormones, often through serial blood or salivary testing, to model the concentration-time profile. Key enzymes in the liver and peripheral tissues, such as aromatase and 5-alpha reductase, play critical roles in the conversion and inactivation of steroid hormones, directly influencing the systemic kinetics and biological effect.

Systemic Hormone Kinetics

Meaning

Systemic Hormone Kinetics refers to the comprehensive study of the entire life cycle of hormones within the body, including their pulsatile secretion rates, transport dynamics via carrier proteins, peripheral metabolism and conversion in target tissues, and eventual clearance and excretion. This analysis provides a complete picture of hormonal exposure and activity at the cellular level.
