What is the Origin of Subcutaneous Peptide Therapy?

The concept of delivering drugs subcutaneously dates back to the mid-19th century, but the specific application for peptide therapy is a modern development driven by advancements in biotechnology and the synthesis of stable, bioactive peptide analogues. This method is an adaptation of established insulin and growth hormone delivery protocols.

What is the Mechanism of Subcutaneous Peptide Therapy?

The mechanism of delivery involves the peptide diffusing from the subcutaneous depot into the local microvasculature, from where it enters the systemic circulation. Once in the blood, the peptide travels to target tissues, where it binds to specific cell-surface receptors, often G-protein coupled receptors. This binding initiates a downstream signaling cascade that modulates cellular function, such as stimulating growth hormone release or regulating inflammatory pathways.

Subcutaneous Peptide Therapy

Meaning

Subcutaneous Peptide Therapy refers to the clinical administration of therapeutic peptides via injection into the subcutaneous tissue, the layer of fat beneath the skin. This route of delivery is chosen for its relative ease of self-administration, consistent absorption profile, and the avoidance of first-pass metabolism in the liver, which can degrade orally ingested peptides. This precision method allows for the systemic delivery of signaling molecules to exert their hormonal or neuromodulatory effects throughout the body. It is a cornerstone of modern restorative and regenerative medicine.
