MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202511124842 A) filed by Swami Rama Himalayan University, Dehradun, Uttarakhand, on Dec. 10, 2025, for 'a system for ocular drug delivery using atenolol loaded microsponges.'
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: "The invention relates to an ocular drug delivery system comprising a microsponge formulation and an in-situ gel formulation. The microsponge formulation includes porous polymeric microsponges of about 7-10 microns containing atenolol entrapped within a matrix of ethyl cellulose and Eudragit RL 100, prepared by an oil in oil emulsion solvent diffusion process wherein an internal phase (containing atenolol, ethyl cellulose, and Eudragit RL 100 dissolved in acetone) is sonicated and introduced dropwise into a continuous phase of light liquid paraffin under high speed agitation with magnesium stearate. The in-situ gel formulation comprises a thermoresponsive polymer (Poloxamer 407) and a viscosity modifying polymer (HPMC K4M) that transitions from liquid to gel at ocular temperature, optionally incorporating additives such as benzalkonium chloride and sodium chloride."
