MUMBAI, India, Jan. 7 -- Intellectual Property India has published a patent application (202511102412 A) filed by Lovely Professional University, Phagwara, Punjab, on Oct. 24, 2025, for 'method for transdermal delivery of vitamin d3 using a natural source controlled-release patch.'
Inventor(s) include Dr. Polu Picheswara Rao; and Dr. Shubham Mishra.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "A method for transdermal delivery of vitamin D3 from natural sources is disclosed, providing slow, sustained release over 24-72 hours. The method involves extracting and purifying vitamin D3 from lanolin or lichen, dissolving it in a carrier solution with naturally derived skin-permeation enhancers, and incorporating it into a hydrogel or polymer matrix. The matrix is cast into thin films, laminated with a hypoallergenic adhesive and breathable protective backing, cut into individual patches, and sealed for stability. Patches are applied to clean, dry skin, allowing passive diffusion into systemic circulation. The method includes evaluation of pharmacokinetics, in vitro skin permeation, dermatological safety, and stability to confirm sustained bioavailability and tolerability. This method enables consistent vitamin D delivery, improved compliance, enhanced bioavailability, and suitability for sensitive populations, representing a scalable, natural-source transdermal supplementation solution."
