What is the Origin of Nasal Spray Peptide Administration?

The technique's origin lies in pharmaceutical science and drug delivery research, stemming from the clinical need for patient-friendly, non-parenteral routes for the administration of large, complex biological molecules like peptides. The nasal mucosa's high vascularity, thin epithelial lining, and large surface area made it an ideal target for rapid systemic absorption.

What is the Mechanism of Nasal Spray Peptide Administration?

The primary mechanism relies on the rapid diffusion of the peptide molecules across the thin, highly permeable nasal epithelial membrane directly into the underlying capillary network and systemic circulation. For central nervous system targeting, the peptide may also utilize the olfactory and trigeminal nerve pathways for direct transport into the brain and cerebrospinal fluid, effectively bypassing the restrictive blood-brain barrier.

Nasal Spray Peptide Administration

Meaning

Nasal Spray Peptide Administration is a non-invasive pharmaceutical delivery method where therapeutic peptides are precisely formulated into a liquid spray and introduced into the nasal cavity for systemic absorption. This route is strategically utilized because it bypasses the harsh environment of the gastrointestinal tract and the rapid first-pass metabolism in the liver, offering a convenient, needle-free alternative to subcutaneous injection for many molecules. This method is particularly advantageous for peptides that target the central nervous system due to the direct access pathway.
