A sensor ( e.g. , an optical sensor) that may be implanted within a living animal ( e.g. , a human) and may be used to measure an analyte ( e.g. , glucose or oxygen) in a medium ( e.g. , interstitial fluid, blood, or intraperitoneal fluid) within the animal. The sensor may include a sensor housing, an analyte indicator covering at least a portion of the sensor housing, and one or more therapeutic agents. The one or more therapeutic agents may reduce deterioration of the analyte indicator. The one or more therapeutic agents may be incorporated within the analyte indicator, a membrane covering at least a portion of the analyte indicator, and/or one or more drug eluting polymer matrices, which may be external to or within the sensor housing. |
