  • Patent number: 9278132
    Abstract: A stable ophthalmic pharmaceutical composition for relief, treatment, control, alleviation, or prevention of a pathological ocular condition of the eye comprises: (a) a first polymer, a viscosity of which changes with a change in a concentration of an electrolyte, such as a salt, when added to said first polymer; (b) a second polymer that is different from the first polymer and can modify the viscosity of the first polymer; and (c) an oil. In some embodiments, the composition further comprises a non-ionic surfactant. The composition can form a stable oil-in-water emulsion on storage, but separate into an oil phase and a water phase when applied in the eye. The emulsion can comprises an ophthalmic active pharmaceutical ingredient dissolved in the oil or water phase. The emulsion can provide enhanced stability to said active pharmaceutical ingredient.

  • Publication number: 20110183946
    Abstract: A complex comprises at least an ?2-adrenergic receptor agonist and a compound that provides an opposite charge to a charge on the ?2-adrenergic receptor agonist, wherein the complex is charge neutral as a whole and has a solubility in a range from about 0.3 ?g/ml to about 2.5 mg/ml in water at pH of about 7 and temperature of about 25° C. The complex is included in a composition, device, or implant for use in the neuroprotection of components of a neurological tissue to prevent progressive degeneration of such components. In particular, such a composition, device, or implant can be used to provide neuroprotection to cells and components of the optic nerve system or to inhibit progression of damage to the optic nerve system resulting from glaucoma.

  • Publication number: 20100305514
    Abstract: An ophthalmic injection system having coaxial cannulae includes a plurality of syringe bodies and a plurality of cannulae, wherein a first non-flexible cannula is configured to accommodate and guide a second cannula that moves inside the first cannula and penetrates into the internal cavity of an eye globe. The first cannula is long enough to penetrate one or more outer layers of the eye globe. A syringe body is connected to the second cannula for accommodation and infusion of a pharmaceutical composition. A plunger is inserted into an annular space of the second syringe body at its distal end for injecting the pharmaceutical composition to the surgical site.

  • Publication number: 20100104551
    Abstract: A composition of a long-acting enzyme comprises the enzyme in a formulation comprising a buffer and an additive selected from the group consisting of tranexamic acid, ?-aminocaproic acid, and analogs of L-lysine other than tranexamic acid and ?-aminocaproic acid, combinations thereof, and mixtures thereof. The composition can further comprise another additive selected from the group consisting of L-lysine, L-arginine, L-ornithine (or its pharmaceutically acceptable salts; e.g., L-ornithine hydrochloride), ?-aminobutyric acid, 5-aminovaleric acid, 7-aminoheptanoic acid, glycylglycine, triglycine, N-?-acetyl-L-arginine, betaine, sarcosine, gelatin, HSA, streptokinase, tPA, uPA, non-ionic surfactants, glycerin, D-sorbitol, combinations thereof, and mixtures thereof. A method for prolonging the activity of an autodegradable enzyme comprises storing the enzyme after manufacture at a low pH, and reconstituting the acidified enzyme before use with a solution containing at least one of such additives.
