    摘要: A method and device for treating a mammalian organism to obtain a desired local or systemic physiological or pharmacological effect is provided. The method includes administering a sustained release drug delivery system to a mammalian organism in need of such treatment at an area wherein release of an effective agent is desired and allowing the effective agent to pass through the device in a controlled manner. The device includes an inner core or reservoir including the effective agent, an impermeable tube which encloses portions of the reservoir, and a permeable member at an end of the tube.

    摘要: An injectable drug delivery device includes a core containing one or more drugs and one or more polymers. The core may be surrounded by one or more polymer outer layers (referred to herein as “coatings,” “skins,” or “outer layers”). In certain embodiments, the device is formed by extruding or otherwise preforming a polymeric skin for a drug core. The drug core may be co-extruded with the skin, or inserted into the skin after the skin has been extruded, and possibly cured. In other embodiments, the drug core may be coated with one or more polymer coatings. These techniques may be usefully applied to fabricate devices having a wide array of drug formulations and skins that can be selected to control the release rate profile and various other properties of the drugs in the drug core in a form suitable for injection using standard or non-standard gauge needles. The device may be formed by combining at least one polymer, at least one drug, and at least one liquid solvent to form a liquid suspension or solution wherein, upon injection, such suspension or solution under goes a phase change and forms a gel. The configuration may provide for controlled release of the drug(s) for an extended period.

    摘要: The invention provides a drug delivery device for latanoprost or latanoprost acid. The device has a core of latanoprost or latanoprost acid which is surrounded by an internal and external sheath. The external sheath has a first cap that is permeable to latanoprost or latanoprost acid. The first cap may comprise polyvinyl alcohol (PVA), and the PVA may be heat cured. In certain aspects, there are one or more additional caps on the ends of the sheaths formed from one or more polymers. In certain aspects, one or more portions of the drug delivery device is substantially impermeable to latanoprost or latanoprost acid. In certain aspects, the latanoprost or latanoprost acid elutes through the first cap into a biological environment. The invention further provides methods for manufacturing the drug delivery device.
