Dissolving Microneedle
Dissolving Microneedle — A transdermal delivery device consisting of micron-scale needles that dissolve in the skin, releasing encapsulated peptides without traditional injection.
What Is a Dissolving Microneedle?
Dissolving microneedles are tiny (200-800 µm) needle-like projections made of water-soluble polymers (hyaluronic acid, CMC, PVP) that encapsulate peptide drugs. Upon skin insertion, the needles dissolve within minutes, depositing the peptide into the dermis for systemic absorption, providing pain-free, needle-free peptide delivery.
Advantages
- Pain-free: Needles too short to reach nerve endings. Self-administered
- Stability: Dry solid-state peptide storage. No cold chain needed
- Bioavailability: 80-100% relative to SC injection for many peptides
- Peptides studied: Insulin, GnRH analogs, PTH, vaccine peptides
