Provided are a composition for preparing a lyophilized preparation, comprising a drug-encapsulating polymer micelle and saccharides and/or polyethylene glycol as a stabilizing agent, a lyophilized preparation and a process for producing them. The lyophilized preparation thus provided is easily restructured to an aqueous preparation using an aqueous medium.

La présente invention concerne une composition destiné à être utilisée dans la préparation d'un produit lyophilisé qui comprend une micelle polymère encapsulant un médicament, et un saccharide et/ou un polyéthylèneglycol en tant qu'agent de stabilisation ; une préparation lyophilisée obtenue à partir de ladite composition ; et des procédés permettant de préparer la composition et la préparation. La préparation lyophilisée peut être à nouveau convertie facilement en une préparation aqueuse à l'aide d'un milieu aqueux.
