Description

无定形盐酸伊伐布雷定及其制备方法与应用 技术领域
本发明属于药物化学领域,具体涉及一种无定形盐酸伊伐布雷定及其制备方法与应用。
背景技术
盐酸伊伐布雷定(Ivabradine hydrochloride),化学名:3-[3-[[(8S)-3,4-二甲氧基-8-双环[4.2.0]辛-1,3,5-三烯]甲基-甲氨基]丙基]-7,8-二甲氧基-2,5-二氢-1H-3-苯并氮杂卓-4-酮盐酸盐,化学结构式如下:
Figure PCTCN2014085997-appb-000001
盐酸伊伐布雷定是由法国施维雅公司开发的第一个选择性和特异性If通道阻滞剂,具有单纯的降低心率作用,用于治疗伴有正常窦性心律、对β受体阻滞剂禁忌或不能耐受的慢性稳定型心绞痛的对症治疗。
关于盐酸伊伐布雷定,目前已开发报道了诸多晶型结构的产品,通常,不同晶型的同一药物在外观、溶解度、熔点、溶出度和生物有效性等方面有差别,甚至可能会有显著的不同,因而会影响药物的稳定性、生物利用度及疗效等。施维雅在中国申请的专利CN1683341A、CN1827600A、CN100404512A,CN1948292A、CN1948293A、CN100402502A、CN100432057A分别报道了α、β、βd、δ、δd、γ以及γd几种晶型的产品。而现有技术中CN101597261A、CN101463008A、CN102050784A、WO2008146308A2等文献也分别报道了无定形晶型的产品,并公开了现有技术中常用的制备无定型盐酸伊伐布雷定产品的方法。上述记载的方法一 般均是以盐酸伊伐布雷定为原料,利用溶剂溶解后,再采用减压浓缩法、混合溶剂结晶法等方法进行结晶处理。但是上述方法在制备无定型盐酸伊伐布雷定产品时都存在重复性差,工艺不稳定的问题,不仅难以控制为单一晶型的产品,同时也不适用于工业化生产的需求。
