What is the Origin of Therapeutic Blood Levels?

This is a fundamental concept in clinical pharmacology and toxicology, establishing the relationship between the dose administered and the concentration achieved at the site of action. The determination of this range is based on extensive clinical trials and pharmacokinetic data.

What is the Mechanism of Therapeutic Blood Levels?

Achieving and maintaining therapeutic blood levels relies on the principles of pharmacokinetics, specifically balancing the rate of absorption, distribution, metabolism, and excretion of the compound. The chosen route of administration and dosing frequency are precisely calculated to ensure the plasma concentration remains above the minimum effective concentration and below the toxic concentration throughout the treatment interval.

Therapeutic Blood Levels ∞ Area

Therapeutic Blood Levels

Meaning

The specific range of concentration of a pharmaceutical agent or hormone in the systemic blood circulation that is empirically or clinically determined to produce the desired physiological benefit with minimal risk of toxicity or adverse effects. Maintaining levels within this range is the primary goal of hormone replacement and optimization therapy to ensure sustained efficacy and patient safety.
