  • Publication number: 20150352177
    Abstract: Methods and compositions are provided for treating an ocular disease in a subject in need thereof by increasing the bioavailability of a drug in the subject's eye. In one aspect, the ocular disease is at least one of diabetic retinopathy, macular degeneration, endopthalmitis, glaucoma, cataracts, ocular herpes. The methods and compositions provided herein include an efflux transporter inhibitor and a drug effective for treating the ocular disease. The efflux transporter inhibitor is effective to reduce the efflux of the drug through at least one of P-glycoprotein (Pgp), breast cancer resistant protein (BCRP), and multidrug resistant associated protein 1-9 (MRP1-9).

  • Publication number: 20150111833
    Abstract: Methods and compositions are provided for treating an ocular disease in a subject in need thereof by increasing the bioavailability of a drug in the subjects eye. By one approach, the ocular disease is endophthalmitis. The methods and compositions provided herein include an efflux transporter inhibitor and a drug effective for treating the ocular disease. The efflux transporter inhibitor is effective to reduce the efflux of the drug through at least one of Pglycoprotein (Pgp), breast cancer resistant protein (BCRP), and multidrug resistant associated protein 19 (MRP19). In one aspect, cyclosporine A is the efflux transporter inhibitor.

  • Patent number: 8691571
    Abstract: A method of sustaining cells is provided. The method can include providing a non-perfluorocarbon cell storage medium, providing a pre-oxygenated liquid perfluorocarbon in contact with the storage medium, and placing the cells in contact with the storage medium but not in contact with the perfluorocarbon. Additionally, the method can result in increased corneal cell viability compared to corneal cells placed in a non-perfluorocarbon cell storage medium without being in contact with a pre-oxygenated liquid perfluorocarbon.

  • Patent number: 6462066
    Abstract: Methods and compositions for treatment of, or protection from, neuropathy resulting from reperfusion injury upon reversal of an ischemic condition, comprising treatment or prophylactic treatment of the patient with an antagonist of the type 3 ryanodine receptor, such that a rise in cytosolic Ca2+ concentration is prevented. Therapeutic compositions containing dantrolene or aminodantrolene are administered to the patient to prevent a rise in cytosolic Ca2+ that would otherwise result in Ca2+-mediated neuronal damage. Treatment of ischemic optic neuropathy by this method is shown, and the methods and compositions presented are also applicable to other ischemic reperfusion neuropathies, such as stroke, reperfusion injury after TPA treatment/carotid endarterectomy, seizures, and excitotoxic retinal damage in glaucoma.
