  • Preservative removal from eye drops
    Patent number: 11723838
    Abstract: A particulate plug for removing a preservative from a solution, suspension, or emulsion comprising a drug is presented. The plug comprises microparticles of oxidized polyolefin (OxPO). The microparticles are irregular-shaped rigid aggregates and are sized and packed to yield a hydraulic permeability greater than 0.01 Da. The OxPO have absorbed portions of a preservative to be removed and/or a drug for delivery in solution, as can the copolymer.
    Type: Grant
    Filed: April 30, 2020
    Date of Patent: August 15, 2023
