  • Publication number: 20120276184
    Abstract: The present invention provides a sustained release latanoprost implant in the form of a thin film comprising latanoprost incorporated in a biodegradable polymer matrix. Preferably, said implant is an intraocular implant comprising a thin film comprising latanoprost incorporated in a biodegradable polymer matrix wherein said implant is configured as a disc or a rolled film that can be inserted into the eye and unrolls to provide a film having a high surface area to volume ratio.

  • Publication number: 20120276186
    Abstract: The present invention provides a sustained release, biodegradable intraocular latanoprost implant for reducing elevated intraocular pressure in an individual in need thereof. The implant can be configured as a film (e.g., a rolled film) or extruded filament, either of which can be inserted into the eye of the individual to provide for extended release of latanoprost for several days. Upon insertion into the eye, a rolled film may unroll to provide a film having a high surface area to volume ratio for drug diffusion.

  • Publication number: 20100124565
    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.
