What is the Origin of Hormone Absorption?

The term is derived from the fundamental pharmacological principles governing drug movement across biological membranes, applied specifically to endogenous or bioidentical endocrine agents. With the advent of diverse non-oral hormone delivery systems, particularly in the mid-20th century, the study of absorption kinetics became a distinct and vital area of clinical endocrinology. This research informed the development of optimized formulations for consistent therapeutic dosing.

What is the Mechanism of Hormone Absorption?

The specific mechanism depends heavily on the route of administration and the physiochemical properties of the hormone molecule. Lipophilic steroid hormones, for instance, are readily absorbed across the skin barrier in transdermal delivery via passive diffusion, bypassing first-pass hepatic metabolism. Conversely, peptide hormones, if administered orally, are subject to enzymatic degradation and must be delivered via injection or specialized formulations to ensure intact passage into the bloodstream, thus maximizing systemic bioavailability.

Hormone Absorption

Meaning

Hormone absorption is the physiological process by which an exogenously administered hormone, such as a steroid or peptide, traverses a biological barrier to enter the systemic circulation and exert its therapeutic effect. This crucial pharmacokinetic step determines the bioavailability and efficacy of various hormone replacement therapies, including oral, transdermal, and subcutaneous delivery methods. Efficient absorption is paramount to achieving and maintaining the target therapeutic concentration necessary for clinical benefit.
