Provided herein are devices, systems, and methods for the removal of preservatives/excipients/stabilizers from pharmaceutical preparations/medicaments. The devices and systems include a resin for the filtering of preservatives from pharmaceutical preparations. The methods allow for a period of time of incubation of the pharmaceutical preparation in the resin that effectively removes preservatives, while at the same time maintaining the required amount or concentration of active compound in the preparation. Also provided herein are devices, systems, and methods for the controlled release of anti-inflammatory agents in an insulin infusion set.

Methods for adhering a hydrogel matrix to a molded polymer substrate and its use as a biosensor, e.g., a continuous or episodic glucose monitor, are disclosed. The presently disclosed subject matter provides a method for adhering a hydrogel matrix to a molded polymer substrate, the method comprising: (a) molding a polymer comprising one or more polymer chains with an oxidizer to form a molded polymer substrate; (b) providing a hydrogel matrix comprising a hydrogel, a component comprising one or more acrylate groups or another functional group that can form one or more radicals upon polymerization in the molded polymer substrate, and a photo initiator; (c) combining the molded polymer substrate and the hydrogel matrix; and (d) curing the combined molded polymer substrate and hydrogel matrix for a period of time.

A container and method for storing a pharmaceutical agent are provided for enhancing the storage time. The storage time of the pharmaceutical agent is improved by reducing the loss of stabilizing agents in the pharmaceutical agent. The storage container is formed from a polyolefin that includes a stabilizing agent in an amount effective to reduce or inhibit the migration of stabilizing agents in the pharmaceutical agent. The polyolefin container is formed with a fatty acid amide such as erucamide for stabilizing insulin that contains m-cresol and/or phenol as stabilizing agents for the insulin. The fatty acid amide incorporated in the container inhibits and/or reduces the rate of migration of the m-cresol and/or phenol into the polyolefin to extend the storage life of the insulin. The container can be a syringe, such as a pre-filled syringe, a storage vial or the flow path of an infusion pump.

A device for sensing analyte concentration, and in particular glucose concentration, in vivo or in vitro is disclosed. An optical conduit, preferably an optical fiber has an optical system at the proximal end of the optical conduit. A sensing element is attached to the distal end of the optical conduit, and comprises at least one binding protein adapted to bind with at least one target analyte. The sensing element further comprises at least one reporter group that undergoes a luminescence change with changing analyte concentrations. Optionally, the sensing element includes reference groups with luminescence properties that are substantially unchanged by variations in the analyte concentrations.
