(KO) 세프디토렌 피복실의 신규 결정 형태 및 이의 제조 방법
Abstract: front page image
(EN)The present invention relates to: a novel crystal form of cefditoren pivoxil readily convertible into an amorphous form, to be used as an active ingredient of a drug, and having high cefditoren pivoxil purity; and a preparation method therefor. The novel crystal form of cefditoren pivoxil shows an XRD pattern having peaks at 2θ values of 8.500±0.2°, 10.535±0.2° and 16.400±0.2°.
(FR)Cette invention concerne : une nouvelle forme cristalline du cefditoren pivoxil facilement convertible sous forme amorphe, pour être utilisée à titre de principe actif dans un médicament, et ayant une pureté de cefditoren pivoxil élevée ; et son procédé de préparation. La nouvelle forme cristalline du cefditoren pivoxil présente un diagramme XRD ayant des pics aux valeurs 2θ de 8,500±0,2°, 10,535±0,2° et 16,400±0,2°.
(KO)본 발명은 약물의 활성 성분으로 사용되는 무정형으로의 전환이 용이하고, 세프디토렌 피복실로서의 순도가 높은 세프디토렌 피복실의 신규한 결정 형태 및 이의 제조 방법에 관한 것이다. 상기 세프디토렌 피복실의 신규 결정 형태는 8.500°±0.2°, 10.535°±0.2° 및 16.400°±0.2°의 2θ에서 피크를 갖는 XRD 패턴을 나타내는 것이다.
