What is the Origin of Exogenous Hormone Delivery Methods?

This term is a fusion of exogenous (from outside the organism) and concepts from pharmacology, specifically drug delivery systems. The clinical necessity arose with the advent of hormone replacement therapy, requiring safe and effective ways to introduce bioidentical or synthetic compounds into systemic circulation. Different methods evolved to mimic natural hormone secretion patterns.

What is the Mechanism of Exogenous Hormone Delivery Methods?

Each method exploits different physiological routes for absorption and distribution to achieve therapeutic blood levels. Transdermal methods utilize the skin for slow, steady absorption, avoiding hepatic first-pass metabolism. Injectable methods provide a rapid or depot effect depending on the vehicle, while oral preparations are subject to liver processing. The mechanism of action is focused on controlling the rate and consistency of hormone entry into the circulation to maintain physiological stability.

Exogenous Hormone Delivery Methods

Meaning

The various clinical techniques and routes utilized to administer hormones or hormone precursors originating from outside the body, bypassing endogenous production. These methods are selected based on the specific hormone’s bioavailability, desired pharmacokinetic profile, and patient compliance. Examples include transdermal creams, subcutaneous injections, oral capsules, and subdermal pellets.
