Description
技术领域
本发明属于药物制剂领域,涉及一种一种塞来昔布片剂及其制备方法。
背景技术
塞来昔布是美国法玛西亚和辉瑞公司共同研发的非甾体类抗炎药物,能特异性地抑制环氧化酶中的Ⅱ型酶蛋白(COX-2)阻断前列腺素生物合成过程、组织前列腺素类炎性物质的产生,从而达到抗炎、镇痛及退热作用。塞来昔布临床上主要用于缓解骨关节炎的症状和体征、缓解成人类风湿关节炎的症状和体征、治疗承认急性疼痛、缓解强直性脊柱炎的症状和体征及家族性腺瘤息肉的辅助治疗,是国内唯一的口服选择性COX-2抑制剂。目前,在国内外上市的塞来昔布制剂仅胶囊剂一种剂型。
塞来昔布由于其晶体结构原因,在水中几乎不溶,属于难溶性药物,理化性质在制剂制备性能中表现极差。首先,塞来昔布在水中几乎不溶,在25℃下水中溶解度仅为0.007mg/ml,在常用的溶出介质中溶出缓慢,如果直接将未经粉碎的药物填充胶囊,未粉碎的塞来昔布是不容易溶解和分散的,因而不能在胃肠道中迅速吸收;第二,质地轻,堆密度低,容易凝聚成块,不易与辅料混合均匀,不但使制剂药物含量均匀度不合格,而且影响吸收。
采用传统的湿法制粒所制得的颗粒流动性较差,且容易产生由于塞来昔布与辅料混合不均匀导致含量均匀度低的现象,溶出度不甚理想。由于药物的溶出是发挥治疗作用的前提,如何促进塞来昔布快速而完全的溶出,提高生物利用度,是本领域技术人员需要着力解决的问题。
中国专利CN202110757801.2公开了一种塞来昔布胶囊及其制备方法,包括塞来昔布、空白丸芯、润湿剂(十二烷基硫酸钠、月桂酰基氨酸钠或月桂醇磷酸酯钾中的一种或两种)、吸收促进剂(甘露醇和/或山梨糖醇)。
中国专利CN201910887558.9公开了一种塞来昔布的固体分散方法及塞来昔布胶囊的制备方法,固体分散方法为:将塞来昔布与药物辅料混合获得原辅料混粉,将原辅料混粉进行超微气流粉碎和/或机械粉碎,所述药物辅料至少包含一水乳糖、十二烷基硫酸钠。
中国专利CN201310134025.6公开了一种塞来昔布泡腾片及其制备方法,包括塞来昔布、有机酸、无机碱、矫味剂、着色剂、润滑剂、填充剂;填充剂选自乳糖或蔗糖,有机酸选自酒石酸或柠檬酸,无机碱选自碳酸氢钠或碳酸钠,矫味剂选自甘草甜素、甘草酸二钠、甘草酸三钠、桔子或水蜜桃香精、阿斯巴甜,着色剂选自赤鲜红或橘黄,润滑剂选自微粉硅胶或滑石粉。
中国专利CN201210003999.6公开了塞来昔布固体分散体及其制备方法,固体分散体含有塞来昔布和载体材料,载体材料选自聚乙烯吡络烷酮、共聚维酮、交联聚维酮中的一种或多种,将塞来昔布和载体材料共同溶解于有机溶剂中,或将载体材料混悬分散在塞来昔布的有机溶剂中,采用减压干燥或喷雾干燥的方式除去有机溶剂即得固体分散体。
中国专利CN201210512342.2公开了一种塞来昔布咀嚼片及其制备方法,咀嚼片包括塞来昔布、崩解剂、填充剂、粘合剂、助流剂、表面活性剂。
