MUMBAI, India, July 11 -- Intellectual Property India has published a patent application (202511060465 A) filed by Meerut Institute Of Engineering & Technology; Sudhanshu; Garima Agarwal; Kartik Sharma; and Parin Singhal, Meerut, Uttar Pradesh, on June 25, for 'buccal strip for sustained-release drug delivery system.'
Inventor(s) include Sudhanshu; Garima Agarwal; Kartik Sharma; and Parin Singhal.
The application for the patent was published on July 11, under issue no. 28/2025.
According to the abstract released by the Intellectual Property India: "This invention discloses a mucoadhesive buccal strip (10) designed for sustained-release drug delivery (30), initially developed as a placebo formulation (20) to optimize the process. The strip comprises a polymer matrix of Hydroxypropyl Methylcellulose (HPMC), Carbopol 940, and Polyvinylpyrrolidone (PVP), combined with a solvent system (40) 8 of ethanol and water. Through a solvent casting process (50), the formulation is cast at 0.5 to 0.7 mm thickness and dried at 40 C to 45 C, yielding a stable, flexible, and uniform strip. The placebo approach (20) enables study of polymer-solvent interactions, mechanical properties (tensile strength 2.5-3.2 MPa, elongation 15-22%), and mucoadhesion (1.8-2.3 N/cm), optimizing parameters without wasting active ingredients. This platform (30) ensures reproducibility, cost-effectiveness, and scalability, providing a foundation for drug-loaded buccal strips for controlled therapeutic delivery."
