Atomic Scale Paired Electron Bonding, Adsorption and Chelation for Removing Preservative Biocidal Agents from Rx and OTC Ophthalmic Therapeutics and Other Medical Solutions

InactiveUS20250367609A1MembranesUltrafiltrationFree solutionFiltration mechanism
Increasing concerns about cytotoxicity caused by traditional ophthalmic product preservatives have driven demand for preservative-free solutions while challenging manufacturers to maintain sterility and safety standards. Inherent user risks have been combined with random manufacturing contamination, resulting in devastating product recalls in recent years. The present invention is a bioactive, affinity filtration system for medical dispensing devices engineered to remove preservatives and contaminants from ophthalmic and other medical solutions when administered. This “just in time” filtration enables manufacturers to follow established preservative practices to ensure safety while delivering a “preservative free” solution upon administration. Without altering the therapeutic formulation, the invention combines adsorption and absorption filtration mechanisms with engineered fullerene derivatives and cellulose acetate membranes to remove preservatives like benzalkonium chloride, thimerosal, and stabilized oxychloro complexes. The invention is designed for integration into established manufacturing, packaging, and stability quality control protocols consistent with the most rigorous antimicrobial patient safety standards.
