ZP Patch Technology

While transdermal drug delivery has been used in a wide variety of successful commercial products for decades, there are challenges in utilizing this technology to deliver certain compounds that cannot permeate the skin's outer layer.

Zosano has developed the ZP Patch Technology – a user-friendly, simple, and needle-free transdermal delivery system consisting of a patch and reusable applicator – that is proven capable of delivering a broad range of compounds, including peptides, proteins, small molecules and vaccines.

ZP Patch Technology delivers a controlled, reproducible dose. Preclinical and clinical testing has demonstrated acceptable skin tolerability.
  

 



The ZP Patch Technology delivers therapeutic compounds via microprojections
that permeate the skins outer layer and provide rapid and efficient systemic delivery and ensure significant therapeutic effect.  Dry coating drug on the thin titanium microprojection array allows for bolus delivery into the skin.  The creation of pathways through the skin improves control of drug distribution throughout the patch treatment area and reduces the potential for skin irritation.
