What is the Origin of Trough and Peak Monitoring?

The terms 'trough' and 'peak' are adopted from pharmacokinetics, the study of drug absorption, distribution, metabolism, and excretion. Applying these concepts to endocrinology allows for a precise understanding of the physiological fluctuations of hormones in a clinical setting. This methodology is crucial for personalized medicine protocols.

What is the Mechanism of Trough and Peak Monitoring?

Monitoring both the trough and peak values provides a complete picture of the hormone's delivery and clearance dynamics, ensuring that the therapeutic range is consistently maintained. A low trough may indicate insufficient dosing or rapid clearance, while an excessively high peak could lead to side effects or receptor downregulation. This precision diagnostic approach prevents the pitfalls of single-point measurements, which often fail to capture the true hormonal exposure over time.

Trough and Peak Monitoring

Meaning

The clinical practice of measuring the concentration of a therapeutic compound or endogenous hormone in the bloodstream at its lowest point (trough, or nadir) and its highest point (peak) within a given dosing interval or diurnal cycle. This method is essential for assessing the efficacy and safety of a personalized hormone regimen. It provides a dynamic profile of hormonal exposure, which is superior to a single measurement.
