MUMBAI, India, Feb. 13 -- Intellectual Property India has published a patent application (202521132652 A) filed by Shri Shankaracharya Institute Of Medical Sciences; Dr. Ruchita Rajendra Dixit; Dr. Amol Ramkrushna Patil; and Dr. Swarnali Das Paul, Durg, Chhattisgarh, on Dec. 27, 2025, for 'shree mata: a nanoparticle-loaded transdermal bindi patch for sustained iron supplementation in women.'
Inventor(s) include Dr. Ruchita Rajendra Dixit; Dr. Amol Ramkrushna Patil; and Dr. Swarnali Das Paul.
The application for the patent was published on Feb. 13, under issue no. 07/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a transdermal patch system for sustained and controlled delivery of ferrous sulfate, providing a non-invasive and patient-friendly alternative for iron supplementation. The invention encompasses conventional patches comprising ferrous sulfate, hydroxypropyl methylcellulose (HPMC), polyvinylpyrrolidone (PVP), and plasticizers, as well as nanoparticle-loaded patches wherein ferrous sulfate nanoparticles are prepared using chitosan via ionic gelation and incorporated into a polymeric film matrix. The patches are fabricated using solvent casting to produce uniform and stable films. In vitro and ex vivo studies demonstrate controlled drug release and enhanced skin permeation, with nanoparticle incorporation improving delivery efficiency. The patches are further evaluated in vivo in an anemia animal model, showing restoration of hematological parameters, including hemoglobin, red blood cell count, and serum iron levels. The invention provides a scalable, reproducible, and effective transdermal system suitable for long-term management of iron-deficiency conditions."
