  • Ophthalmic compositions
    Patent number: 11931415
    Abstract: A composition comprises: a base oil; an additive; and a drug. The additive has segments which are conjugated, e.g. covalently linked, together. A first segment facilitates solubility in the base oil, whereas a second segment facilitates drug solubility and/or modifies drug release or other behaviour. The first segment may for example comprise a poly(dimethylsiloxane)-containing moiety. The second segment may for example resemble a drug molecule. The composition may for example be used as a tamponade or as a component for a tamponade administered to the eye.
    Type: Grant
    Filed: August 9, 2017
    Date of Patent: March 19, 2024
    Assignee: THE UNIVERSITY OF LIVERPOOL
    Inventors: Victoria Kearns, Helen Cauldbeck, Steve Rannard, Rachel Williams, Maude Le Hellaye
  • Ophthalmic compositions
    Patent number: 11707430
    Abstract: A composition comprises: a base oil; an additive comprising a copolymer comprising hydrophobic and hydrophilic units; and a drug. The copolymer may for example have a comb structure in which the hydrophobic units and hydrophilic units are pendant chains on a backbone of the copolymer. The hydrophobic units and hydrophilic units may for example comprise polydimethylsiloxane moieties and ethylene glycol residues respectively. The composition may for example be used as a tamponade or as a component for a tamponade administered to the eye. The invention is useful for solubilising and/or releasing drugs.
