The present invention relates to a stabilized eperisone medical composition, and a sustained-release preparation containing same. More particularly, the present invention relates to a stabilized eperisone medical composition which consists of an eperisone salt and an oxidant as effective ingredients, to thus maintain the chemical stability of the active ingredients during the residence time of drugs in a body as well as the storage of finished products, and also relates to a sustained-release preparation containing the stabilized eperisone which exhibits dual release characteristics of fast- and slow-release because the preparation further includes a release retardant in addition to the eperisone and the oxidant.La présente invention concerne une composition médicale à base d'épérisone stabilisée, et une préparation à libération prolongée contenant celle-ci. Plus particulièrement, la présente invention concerne une composition médicale à base d'épérisone stabilisée comprenant, comme ingrédients efficaces, un sel d'épérisone et un oxydant, pour maintenir ainsi la stabilité chimique des principes actifs pendant le temps de séjour des médicaments dans un corps ainsi que le stockage des produits finis. L'invention concerne également une préparation à libération prolongée contenant l'épérisone stabilisée qui présente des caractéristiques de libération doubles consistant en une libération rapide et une libération lente car la préparation comprend en outre un agent retardant la libération en plus de l'épérisone et de l'oxydant.본 발명은 안정화된 에페리손 의약 조성물 및 이를 함유하는 서방성 제제에 관한 것으로, 좀더 상세히 설명하면 활성성분인 에페리손 염과 산성화제로 구성되어 있어서 완제품 보관 도중에는 물론 약물이 환자 체내에 체류하는 도중에도 활성성분의 화학적 안정성을 유지시켜 주는 안정화된 에페리손 의약 조성물과, 상기 에페리손과 산성화제 이외에 방출지연제를 추가적으로 포함하고 있어서 속효성과 지효성의 이중 방출특성을 나타내는 안정화된 에페리손 함유 서방성 제제에 관한 것이다.
