  • Patent number: 8529927
    Abstract: Biocompatible intraocular implants include an alpha-2 adrenergic receptor agonist and a polymer associated with the alpha-2 adrenergic receptor agonist to facilitate release of the alpha-2 adrenergic receptor agonist into an eye for an extended period of time. The alpha-2 adrenergic receptor agonist may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. The implants can be placed in an eye to treat one or more ocular conditions, such as an ocular vasculopathy or glaucoma, including reduction of an elevated intraocular pressure.

  • Patent number: 8465759
    Abstract: A process for the preparation of a bioadhesive laminate comprising a hot-melt extruded reservoir layer and a hot-melt extruded backing layer is provided. The reservoir layer comprises a thermoplastic bioadhesive composition containing an active agent. An active agent-containing thermoplastic bioadhesive hydrophilic composition is hot-melt coextruded with a hydrophobic composition to form at least a bi-layered laminate. The hydrophilic composition and the hydrophobic composition have at least one polymer in common. In addition, the melt flow index of the hydrophobic composition is within 50% of the melt flow index of the hydrophilic composition. As a result, the laminate has a uniform transverse cross-section and/or a uniform longitudinal cross-section throughout a major of the length of the laminate. Moreover, when the laminate is divided into unit doses of approximately the same size, they have a high degree of content uniformity with respect to the active agent(s) present therein.
