Description

一种电荷平衡的复合物、其制备方法及其用途 技术领域
本发明属于制药领域,具体涉及一种电荷平衡的复合物、其制备方法及其用途。
背景技术
纤维化(fibrosis)是一种间质纤维结缔组织(细胞外基质)大量增生对缺损组织进行修复,发生纤维化的病理改变。其主要病理改变为器官组织内纤维结缔组织增多,实质细胞减少,持续进展可致器官结构破坏和功能减退,乃至衰竭,严重威胁人类健康和生命。
近年来,纤维化疾病发病率和死亡率不断升高,发病人群众多。尽管近年来对纤维化过程的认识有显著进展,但纤维化疾病的致病因素以及病理机制尚不完全清楚,目前尚无逆转或完全阻止纤维化疾病发展的有效治疗方法。纤维化疾病可累及多个脏器或者多系统,包括肺脏、肝脏、肾脏、心脏纤维化,以及系统性硬化症、多灶性纤维化、硬皮病等等,其共同特征是大量的成纤维细胞聚集、细胞外基质在组织中的过度沉积、组织损伤所致的结构破坏,组织器官功能不断丧失。
目前,现有技术中已提出了多种用于治疗纤维化疾病的药物。例如中国发明专利申请“CN109922803A赖氨酰氧化酶样2抑制剂的用途”中提出了多种能够用于治疗纤维化疾病的药物或药物组合。
血管紧张素Ⅱ受体拮抗剂,包括沙坦类化合物,为一类高血压治疗药物。通过阻断AngⅡ效应降低血压。现已广泛用于临床。主要用于临床高血压病及其他心肾疾病的治疗。血管紧张素转化酶抑制剂(ACEI),包括普利类化合物,具有降压作用,可以延缓和逆转心室重构,阻止心肌肥厚的进一步发展,改善血管内皮功能和心功能,减少心律失常的发生,还能提高生存率,改善预后。血管紧张素Ⅱ受体拮抗剂和血管紧张素转化酶抑制剂在临床上已经用于治疗肾纤维化等纤维化疾病(CN201811513140.3一种治疗肾脏纤维化的二黄益肾中药组合物)。
H1组胺受体拮抗剂,包括氯雷他定、地氯雷他定和卢帕他定等,主要用于阻断组胺H1受体,抑制粘附分子介导的炎症反应,以及抗乙酰胆碱作用、抗炎、抑制中枢神经系统、抗晕动、抗呕吐,抗咳嗽、抗惊厥和局部麻醉等。 在中国专利申请“CN102145002B卢帕他定在治疗和预防肺纤维化方面的用途”中公开了H1组胺受体拮抗剂卢帕他定在治疗或预防肺纤维化中的用途。
纤维化可能涉及人体所有的组织及器官,且诱因、成因复杂,所以临床上尚缺乏对所有纤维化疾病都具有针对性的有效治疗方法。此外,人们仍然希望继续提高药物对纤维化疾病的治疗效果。因此,有必要继续开发新的治疗纤维化的药物,为临床治疗提供更多新的选择。
发明内容
针对现有技术的缺陷,本发明提供一种电荷平衡的复合物、其制备方法及其用途,目的在于提供新具有预防和治疗纤维化疾病的药物,为纤维化疾病的临床治疗提供更多的选择。
一种电荷平衡的复合物,所述电荷平衡的复合物由抗组胺类药物与抗高血压药物组成,或由抗组胺类药物与抗高血压药物复合而成。
优选的,它是由抗组胺类药物与抗高血压药物形成的共结晶。
