Abstract: A method is provided for making a fabric. The method comprises (a) providing a composition comprising a plurality of nanocrystals disposed in a liquid medium, the nanocrystals comprising a material elected from the group consisting of a Group IV element; (b) applying the composition to a porous substrate, thereby removing at least a portion of the liquid medium from the nanocrystals; and (c) removing the nanocrystals from the porous substrate as a self-supporting mass.

Abstract: The invention provides starch-based microparticles with high loading capacity for the stabilization and/or controlled release of one or more agents, for example, a pharmaceutical, a taste masking agent, a flavoring agent, or a combination thereof, disposed within the microparticles, and to methods of making and using such microparticles.

Abstract: Disclosed is a misuse preventative, controlled release composition in the form of a multilayered oral dosage form. A first layer contains a plurality of controlled release microparticles having a pharmaceutically active agent (for example, an opioid analgesic) disposed therein. The second layer, which can be adjacent the first layer comprises a pharmaceutically active agent that can be the same or different from the pharmaceutically active agent in the microparticles in the first layer. The composition further comprises a superabsorbent material (for example, polycarbophil) disposed within the first layer, the second layer, or both the first layer and the second layer. When intact, the pharmaceutically active agent is released from the second layer faster than the pharmaceutically active agent in the first layer.

Abstract: Disclosed is a misuse preventative, controlled release formulation comprising a core comprising a superabsorbent material (for example, polycarbophil), a controlled release coat surrounding the core, and a plurality of controlled release microparticles having a pharmaceutically active agent (for example, an opioid analgesic) disposed within the core, the coat, or both the core and the coat. When crushed, either intentionally or accidentally, and exposed to an aqueous medium, the superabsorbent material present in the core swells to encapsulate the microparticles, which remain substantially intact thereby retarding the release of the pharmaceutically active agent from the formulation. Also disclosed is a method of using the misuse preventative, controlled release formulation to deliver a pharmaceutically active agent to a mammal, for example, a human, in need thereof.

Abstract: The instant invention relates to a solid product comprising a liquid biologically active agent which is intimately associated to a stabilizing agent; particularly a solid product that can be reconstituted to a clear, stable, stabilized nanodispersion or loaded micelles comprising a polymer as a stabilizing agent and a liquid, preferably water immiscible, biologically active agent. The instant invention is further directed toward a process for the production of the above solid product; particularly to micelles or nanodispersions produced by hydration of a cake or powder of the solid product, produced via an effective treatment of a stabilized solution comprising for example a polymer as a stabilizing agent, such as an amphiphilic block copolymer or a small molecular weight surfactant, loaded with a liquid biologically active agent, such as propofol, an optional additive, and a suitable solvent.

Abstract: The invention relates to a sustained release formulation for delivering one or more pharmaceutically active agents. The formulation comprises cross-linked high amylose starch and at least one pharmaceutically active agent, and optionally can be subdivided into smaller dosage forms where the smaller dosage forms have substantially the same sustained release properties as the formulation from which they were derived. The formulations can provide sustained release for up to at least 24 hours, and because of their divisability permits a recipient of the active agent or the person administering the active agent to titrate the dosage of the agent.

Abstract: The invention relates to a once a day formulation of trazodone or a trazodone derivative. The formulation contains trazodone or a trazodone derivative and a controlled release excipient so that, once administered orally, the trazodone or the trazodone derivative is maintained at a therapeutic plasma concentration from at least 1 hour to at least 24 hours after initial administration. After administration, the initial therapeutic action takes effect within the first hour and lasts at least about 24 hours. This therapeutic effect remains relatively and substantially stable for the remaining period of 24 hours. The formulations can be used for treating depression and/or sleeping disorders.

A first layer contains a plurality of controlled release microparticles having a pharmaceutically active agent (for example, an opioid analgesic) disposed therein. A second layer comprises a superabsorbent material. When crushed, either intentionally or accidentally, and exposed to an aqueous medium, the superabsorbent material creates a hard gel that traps the microparticles. The hard gel and microparticles provide controlled release of the pharmaceutically active agent.
