MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202611066496 A) filed by Dr. Praveen Kumar; Saloni Jaswal; Sandhya Negi; Sanjeev Kumar; Shalini Barthwal; Shivam Kashyap; Sikander Rana; and Shri Ram Kumar on May 27, 2026, for A Three-Dimensionally Printed Patient-Specific Multi-Compartment Drug Delivery System With Programmable Release Geometry And Embedded Dose Verification Features.
Inventors include Dr. Praveen Kumar; Saloni Jaswal; Sandhya Negi; Sanjeev Kumar; Shalini Barthwal; Shivam Kashyap; Sikander Rana; and Shri Ram Kumar.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The present invention relates to a three-dimensionally printed patient-specific multi-compartment drug delivery system comprising a printed dosage body having a plurality of drug-containing compartments, isolating walls, release-controlling barrier regions, programmable release pathways, and an embedded dose verification feature. The system is configured to convert a patient-specific digital prescription profile into a locked printable geometry defining drug compartment volume, compartment location, barrier thickness, release channel dimensions, and verification structure. The programmable release pathways regulate drug release by physical geometry including channel length, channel diameter, porosity, tortuosity, rupture membranes, dissolvable plugs, and gradient-density regions. The isolating walls reduce premature interaction between incompatible active pharmaceutical ingredients, while the embedded verification feature enables confirmation of dose identity, printed architecture, and release configuration before dispensing. The invention provides customized drug delivery, improved dose accuracy, reduced medication burden, controlled release performance, and enhanced safety in personalized pharmaceutical manufacturing.
