PROBLEM TO BE SOLVED: To provide a sustained release preparation which can slowly release an ordinary temperature volatile drug component easy to vaporize in a short period, has a small amount of waste, can easily judge the disappearance of the effect of the drug component, has high safety to the human body, furthermore can incorporate a drug component at high concentration, and is easy to adjust the content of the drug component and a method for producing the same.SOLUTION: The sustained release preparation is obtained by mixing a silane alkoxide hydrolyzate fluid with a drug component volatile at normal temperatures to form a mixed fluid and adding a curing catalyst to this mixed fluid to solidify the resulting mixture.COPYRIGHT: (C)2010,JPO&INPIT【課題】短期間で気化し易い常温揮発性薬剤成分を緩やかに放出することができ、廃棄物量が少なく、薬剤成分の効果の消失を容易に判別することができ、人体への安全性も高く、さらに薬剤成分を高濃度に含有させることができ、薬剤成分の含有量の調整が容易な徐放性製剤とその製造方法を提供する。【解決手段】シランアルコキシド加水分解液と、常温揮発性薬剤成分とを混合し、この混合液に硬化触媒を添加して固化したものであることを特徴とする。【選択図】なし
