Medicinal Compositions and Method for the Preparation Thereof |
摘要 |
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-R<SUP>1</SUP>-C(O)]<SUB>n</SUB>- wherein: "R<SUP>1</SUP>" 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.
