  • Publication number: 20120065228
    Abstract: A composition for treating, controlling, reducing, or ameliorating inflammatory pain comprises a dissociated glucocorticoid receptor agonist (“DIGRA”), a prodrug thereof, a pharmaceutically acceptable salt thereof, or a pharmaceutically acceptable ester thereof. The composition can comprise an additional anti-inflammatory agent and can be formulated for topical application, injection, or implantation. It may be used in a method of managing ocular inflammation and/or pain such that it has lower risk of eliciting increased intraocular pressure seen with glucocorticoids.

  • Publication number: 20110077270
    Abstract: A composition for treating or controlling an ocular disease or condition comprises a dissociated glucocorticoid receptor agonist (“DIGRA”), which disease or condition has an etiology, or results, in inflammation. The composition can optionally include an anti-inflammatory agent, an anti-infective agent, or both. The composition can be formulated for topical application, injection, or implantation in an affected eye to treat or control the ocular inflammatory disease or condition.

  • 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.

  • Publication number: 20070134230
    Abstract: A method for prolonging the activity of an autodegradable enzyme comprises storing the enzyme after manufacture at a pH less than about 5, and reconstituting the acidified enzyme substantially immediately before use with a buffer having a pH in the range from about 6.5 to about 11, wherein the pH remains within 1 pH unit upon adding said the enzyme into the buffer. The method is useful to provide enzyme for wide use, which otherwise would lose activity upon long storage. In one embodiment the method is applicable to provide enzyme for inducing controlled posterior vitreous detachment.

  • Publication number: 20070049559
    Abstract: Preparations for controlling intraocular pressure in the eye comprise as an active compound, arylazine substituted with a carbonylic moiety, which compound is capable of effecting a “pharmacological trabeculocanalotomy” in an eye by means of reducing juxtacanalicular meshwork to promote outflow of aqueous. The organic active compound increases Gelatinase A activity in ocular cells by increasing cell membrane expression of membrane-type matrix metalloproteinases (MT-MMPs) to increase aqueous outflow as a treatment for glaucoma, e.g., primary open angle glaucoma.

  • Publication number: 20060121090
    Abstract: Compositions capable of effecting a “pharmacological trabeculocanalotomy” in an eye by means of reducing juxtacanalicular meshwork as a barrier to outflow of aqueous. The small organic molecules increase Gelatinase A activity in ocular cells by increasing cell membrane expression of membrane-type matrix metalloproteinases (MT-MMPs) to increase aqueous outflow as a treatment for primary open angle glaucoma.
