Abstract: Implantable drug delivery systems target delivery of small volumes of drugs to specific tissues. In some cases, a drug delivery system includes an implantable osmotic pump connected to a drug-containing housing, with that housing connected to a needle, cochlear implant or other type of component for ultimate delivery to the target tissue. In some implementations, a subcutaneous port receives a fluid from an external pump. The port is connected to a needle or other component for delivery of one or more drugs to the target tissue. Both solid and liquid drug formulations can be used. In embodiments using solid drugs, a separate drug vehicle (such as saline) can be used to dissolve a portion of the solid drug, with the drug-loaded vehicle then delivered to the target tissue.

Abstract: An apparatus may include a needle for sustained delivery of drugs and other agents to the inner ear or other tissues of a human or an animal. The needle can include an insertion stop, and can be placed through the round window membrane or through a surgically-prepared hole in a bone. The needle can be in fluid communication with a port and/or with a micro-infusion or osmotic pump. A cochlear implant electrode can be used instead of a needle.

Abstract: Improved formulations of gacyclidine for direct administration to the inner or middle ear.

Abstract: A method is provided for the preparation of compounds of the formula (R1)(R2)NC(?X)S(O)nR3 or (R1)(R2)NC(?X)OS(O)nR3, wherein R1, R2 and R3, X and n have any of the meanings defined in the specification. A method is also provided for the detection and quantitation of compounds of the formula (R1)(R2)NC(?X)OS(O)nR3. A method to link a therapeutic agent to a compound that is conjugated to glutathione is also provided for the purpose of improving the therapeutic properties of the therapeutic agent. Novel compounds, intermediates, pharmaceutical compositions and methods of use are also provided.

Abstract: Disclosed are novel compounds and novel pharmaceutical compositions for use in medical therapy, as well as intermediates and processes for preparing such compounds. Therapeutic methods for preventing or treating glutamate-related disorders in a mammal and methods to inhibit or prevent glutamate binding in mammalian tissue are also disclosed.
