Sterile complex of therapeutic peptide bond to a polysaccharide

摘要

A sterile composition comprising a therapeutic peptide complexed to a biopolymer dispersed in or on a pharmaceutically acceptable carrier, wherein the peptide is preferably a growth factor and wherein the biopolymer is selected from structural proteins such as collagen and polysaccharides such as cellulose, is prepared by sterilising the peptide/biopolymer complex before dispersing said complex in or on the carrier. Also claimed is the method of preparation of a sterile peptide consisting of complexing said peptide with a biopolymer, sterilising said complex and, finally, separating said peptide from said biopolymer.
