A CONTROLLED-RELEASE, PARENTERALLY ADMINISTRABLE MICROPARTICLE PREPARATION

摘要

A parenterally administrable, biodegradable microparticle preparation, preferably composed of amylopectin-containing starch. The preparation contains a biologically active substance which, during the first 24 hours after injection, exhibits a release of the active substance that is less than 25 % of the total release, determined from a concentration-time curve in the form of the ratio between the area under the curve during the said first 24 hours and the total area under the curve in question.
