Description
本申请要求享有2021年4月13日向中国国家知识产权局提交的申请号为CN202110395930.1，名称为“一种布瑞哌唑口腔薄膜剂、其制备方法及应用”的发明专利申请的优先权。该申请的全文以引用的方式并入本文。
技术领域
本发明涉及一种布瑞哌唑口腔薄膜剂、其制备方法及应用。
背景技术
布瑞哌唑片由日本大冢制药株式会社和丹麦灵北制药有限公司共同开发，并于2015年7月在FDA批准上市，剂型为片剂，规格为0.25mg、0.5mg、1mg、2mg、3mg和4mg。
布瑞哌唑片作为5-HT1A受体及多巴胺D2受体激动剂，5-HT2A受体拮抗剂，临床上用于重度抑郁症和精神分裂症的治疗。用于重度抑郁症治疗时，起始剂量为0.5mg/天或1mg/天，然后增至目标剂量2mg，每日一次，最大推荐剂量为3mg/天；用于精神分裂治疗时，起始剂量为1mg/天，推荐目标剂量为2mg至4mg，每日一次，最大推荐剂量为4mg/天。布瑞哌唑在多个单胺系统具有广泛的活性，对多巴胺D2受体的部分激动剂活性下降，且对特定5-HT受体(如5-HT1A、5-HT2A、5-HT7)的亲和力提高，具有更好的疗效和耐受性，可减少患者静坐不能、不安或失眠等不良反应。
布瑞哌唑为白色或类白色结晶粉末，在水中几乎不溶，且自身具有苦麻刺激感，可在口腔粘膜引起显著的刺激感觉。
布瑞哌唑普通片必须现在胃中崩解才能开始释放药物，起效慢，从而限制生物利用度。服用也不方便，作为精神类疾病的治疗药物，该适应症人群在配合治疗方面较差，易发生拒绝治疗、藏药、吐药等情况。专利CN105078910A公开了一种布瑞哌唑口崩片制备方法，将含有布瑞哌唑采用冻干技术制备成冻干口崩片，使其崩解速度加快，提高溶出。但该技术相对繁琐，生产需要专门设备，产品造价高，且制备的制剂较容易碎裂，不适于运输，增加了包装、运输难度。且服用时不能沾水，提高对患者的要求，不利于精神分裂患者的顺应性。
专利CN105395528A公开了一种布瑞哌唑口腔速溶膜，但由于布瑞哌唑在水中几乎不溶，难以分散在亲水性的胶液中，在刮涂烘干过程中，药物易发生团聚现象，从而影响主药的含量均匀度。同时患者服用后也会有口感不适的现象，影响顺应性。
因此，迫切需要开发服用方便、患者顺应性好、生物利用度高、适合于工业化生产的布瑞哌唑的剂型。
发明内容
