求助塞来昔布晶型?查到的专利里确实说晶型III稳定,但也说它水溶性差,不容易吸收啊!你确定药用的是晶型III么?推测还是确实查到的?... 当然是查到的 这东西能乱说么。。就是查专利 我也要看专利的单位在所在国有没有上市的药品 是保护自己的产品还是随便申请东西用的 坛子里果然搞技术的多。。不会说话呢。。下面是复制的上市资料里的文本: Three polymorphic forms of celecoxib, distinguishable by powder X-ray diffraction (PXRD) have been isolated. Solid-state interconversion between the forms at low temperatures has not been observed. All GLP lots of celecoxib consisted of stable Form III polymorph. Following pin milling only the thermodynamically stable polymorph, Form III, is produced.查看更多
