MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202611050677 A) filed by Swami Vivekanand Subharti University, Meerut, Uttar Pradesh, on April 21, for 'a dual-enhanced nanoemulsion multi-layer herbal transdermal patch for controlled sustained anti-inflammatory delivery and enhanced permeation.'
Inventor(s) include Dr. Varsha Raj.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a multi-layer nanoemulsion-loaded transdermal patch comprising standardized herbal anti-inflammatory actives for controlled and enhanced dermal delivery. The patch incorporates a nanoemulsion containing curcumin, boswellic acids, and gingerol in a synergistic ratio, having a droplet size in the range of 20-80 nm, thereby improving solubility and skin permeation. The nanoemulsion is embedded within a polymeric matrix comprising HPMC and PVP, and integrated into a multi-layer structure including a backing layer, drug reservoir, rate-controlling membrane, and adhesive layer. The system enables dual permeation enhancement through nanoscale transport and terpene-based penetration enhancers, resulting in increased transdermal flux. The patch provides a biphasic release profile with an initial priming dose followed by sustained release over 12-24 hours. The invention improves bioavailability, reduces dosing frequency, minimizes gastrointestinal side effects, and provides a non-invasive, stable, and effective therapeutic solution for inflammatory conditions."
