    摘要: A pH-dependent sustained release, drug delivery composition capable of being formed into tablets or pellets, wherein the release is controlled by a diffusion barrier formed by the interaction of a pH-dependent gelling material and a pH-independent non-gelling material, comprising a polymer matrix comprising, by weight, (a) 10 to 50% sodium alginate, (b) 2 to 15% propylene glycol alginate and (c) 40 to 80% of a pharmaceutical medicament.

    摘要: Prostheses with improved chemical and mechanical properties manufactured that includes a radiation resistant and hydrolytically stable biocompatible fabric having outer and first and second ends with a textile fabric that includes a naphthalene dicarboxylate derivative polymer having the general formula: wherein R1 and R3 are the same or different groups and are independently selected from the naphthalene dicarboxylate derivative repeating unit (I), a hydrogen radical and a methyl radical. R2 is an alkylene radical having 1 to 6 carbon atoms; n is from 10 to 200. Also contemplated are implantable prostheses that are flat constructions useful as patches and filters or tubular constructions useful as vascular grafts. A further aspect of this invention provides a method for making a radiation and thermal resistant and hydrolytically stable, steam sterilizable biocompatible prosthesis.
