  • Compositions and methods for reducing ocular hypertension
    Patent number: 6770675
    Abstract: An improved ophthalmic composition, including docosanoid active agents, which is especially useful in lowering intraocular pressure associated with glaucoma. Improvements in IOP reduction efficacy, preservative efficacy and reduced additive concentrations are achieved by utilizing the disclosed compositions which include a docosanoid active agent (e.g., isopropyl unoprostone), in conjunction with selected non-ionic surfactants, preservatives, and non-ionic tonicity adjusting agents.

  • Process for preparing stabilized chitin derivative compounds
    Patent number: 5773608
    Abstract: A process for sterilizing a polysaccharide composition containing chitosan, a chitosan derivative or a chitin derivative without substantially degrading the polysaccharide. The process has the steps of blending the polysaccharide in a solvent to form a solution or suspension; sterilizing the solution or suspension; dissolving suspended particles, if present; and then aseptically adjusting the pH of the sterilized solution. There is additionally provided a polyol stabilizing agent suitable for the polysaccharide composition.
