  • Patent number: 5032392
    Abstract: An aqueous ophthalmic preparation is described for the treatment of dry and/or irritated eyes. The preparation is comprised of retinol and/or derivatives or precursors thereof, solubilized in water. Certain non-ionic surfactants and propylmethylcellulose are disclosed as solubilizing agents, with propylmethylcellulose also acting as a mucin-like constituent. The vitamin-containing preparation also contains (1) free radical scavenging compounds and (2) compounds capable, in solution, of chelating multivalent metal cations present in human and/or animal external eye tissue or tear film. The preferred free radical scavenger is mannitol. The preferred chelating agent is EDTA, present in minimal quantities for chelating certain catalytically active metallic ions present at or near the surface of the eye. Also described are tonicity adjusting compositions and an ophthalmic solution buffering system comprising citric acid and citrates.
