A controlled-release, parenterally administrable microparticle preparation

摘要

A parenterally administrable, biodegradable microparticle preparation containing 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
