    • Methods for the manufacture of medicinal compositions are described. A method for the manufacture of a medicinal composition according to the invention comprises: (a) Providing a biocompatible polymer of the general formula —[O—R1—C(O)]n— wherein: “R1” is a linear, branched, or cyclic organic group, “n” is at least three, (b) Acylating the biocompatible polymer to provide an acylated biocompatible polymer and a mixed anhydride; (c) Reacting the mixed anhydride with a nucleophile to provide an acylated biocompatible polymer with a terminal carboxylic acid derivative capable of being chemically converted to an acid in the absence of water, (d) Converting the terminal carboxylic acid derivative to an acylated biocompatible polymer with a terminal carboxylic acid; and (e) Combining the acylated biocompatible polymer with a drug to provide the medicinal composition.
    • 描述了药物组合物的制造方法。 制备根据本发明的药物组合物的方法包括:(a)提供具有通式的生物相容性聚合物 - [OR 1 -C 2 -C(O)] n 其中:“R 1”是直链,支链或环状有机基团,“n”为至少三个,(b)酰化生物相容性聚合物以提供酰化生物相容性聚合物和混合 酐; (c)用亲核试剂反应混合酸酐以提供酰化的生物相容性聚合物,其具有能够在不存在水的情况下化学转化为酸的末端羧酸衍生物; (d)将末端羧酸衍生物与末端羧酸转化成酰化生物相容性聚合物; 和(e)将酰化的生物相容性聚合物与药物组合以提供药物组合物。
