    摘要: A composition for the sequestration and sustained delivery of an active ingredient in the form of porous particles, the composition comprising the product of the controlled dehydration of particles formed by the reaction of a polymeric anionic material with a polyvalent cation. The composition may be loaded with an active ingredient by soaking the particles in a solution of the active ingredient; and may then be dehydrated. They may then be soaked in a solution of a polymeric cationic material, to form particles providing the controlled release of the active ingredient.

    摘要: Carboxypolysaccharides (CPS) including carboxymethyl cellulose and their derivatives are provided that can be made into sponges, gels, membranes, particulates and other forms, for a variety of antiadhesion, antithrombogenic, drug delivery and/or hemostatic applications during surgery and pharmacological therapeutics. CPSs derivatized with primary amines can be used alone or in combination with poly(ethylene glycol) and poly(ethylene oxides) and other poly(alkylene oxides) to form materials having improved drug delivery, antiadhesion, and hemostatic uses. Applications include other types of chemical modifications of CPS to provide hydrogen, ionic, Van der Walls interactions and/or covalent bonding with drugs, biologicals and other therapeutic or diagnostic purposes.
