What is the Origin of Somatotropin Secretagogue Therapy?

The therapy is a modern development in endocrinology, stemming from the discovery and detailed characterization of Growth Hormone-Releasing Hormone (GHRH) and Ghrelin, the two primary endogenous secretagogues. The term combines 'somatotropin,' the hormone itself, with 'secretagogue,' a substance that causes another substance to be secreted. It is rooted in the clinical goal of optimizing the body's intrinsic hormonal production and regulatory capacity.

What is the Mechanism of Somatotropin Secretagogue Therapy?

The secretagogue agents bind to specific receptors on the somatotroph cells in the anterior pituitary, mimicking the action of GHRH or Ghrelin, which signals the cells to release stored GH. This method is preferred clinically because the release pattern remains physiological, subject to the body's natural negative feedback mechanisms, which helps to mitigate the risks associated with non-pulsatile, supraphysiological dosing of synthetic GH. The therapy aims to restore a more youthful, dynamic hormonal milieu.

Somatotropin Secretagogue Therapy

Meaning

Somatotropin Secretagogue Therapy is a clinical intervention that utilizes pharmaceutical agents, known as secretagogues, to stimulate the pituitary gland to increase its natural, pulsatile secretion of somatotropin, or Growth Hormone (GH). This therapeutic approach is designed to safely elevate systemic GH and its downstream mediator, Insulin-like Growth Factor 1 (IGF-1), thereby promoting anabolic effects, improved body composition, and enhanced metabolic function. It is a nuanced, indirect alternative to the direct administration of exogenous growth hormone.
