MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511124844 A) filed by Swami Rama Himalayan University, Dehradun, Uttarakhand, on Dec. 10, 2025, for 'a controlled drug delivery system for acetazolamide loaded eudragit microspheres.'

Inventor(s) include Ganesh Kumar.

The application for the patent was published on Jan. 23, under issue no. 04/2026.

According to the abstract released by the Intellectual Property India: "This invention relates to the field of controlled drug delivery systems and presents a novel formulation for acetazolamide-loaded Eudragit microspheres prepared using a Box-Behnken design approach. An organic phase is formulated by dissolving Eudragit RS100 and acetazolamide in a water immiscible solvent mixture of ethanol and dichloromethane, while an external aqueous phase containing water and sodium lauryl sulfate serves as a medium for emulsion formation. A three blade motorized stirrer disperses the organic phase into the aqueous phase to generate uniform droplets, which are subsequently hardened by controlled organic solvent evaporation. The method employs a quadratic polynomial model to adjust critical formulation parameters including the drug to polymer ratio, surfactant concentration, and stirring speed, thereby optimizing particle size distribution and drug entrapment efficacy."
