PURPOSE: To obtain the titled slow-releasing agent by supporting a peptide having growth-promoting activity or osteometabolism-relating action on a low- toxic carrier decomposable in living body and administrable to body, such as a specific protein, polymeric saccharide, etc. n CONSTITUTION: A growth-promoting peptide (e.g. growth hormone) or a peptide having osteometabolism-relating action (e.g. calcitonin) is supported on a carrier consisting of a mixture of one or more substances decomposable in living body, administrable to the body and having low toxicity, e.g. a protein such as collagen, gelatin, albumin, etc., a polymeric saccharide such as chitin, a synthetic polymer such as polylactic acid, polyglycolic acid, polyglutamic acid, etc. The product is formed in the form of an injectable suspension injection or a sphere, cylinder, needle, disk, etc., suitable for the part to be applied. It releases the growth-promoting component, etc., for a long period. n COPYRIGHT: (C)1986,JPO&Japio |
