Abstract

含有有效成分glimepiride的药物组合物。该组 合物用于预防或治疗动脉硬化,对脂代谢和血浆胰岛 素水平的增加没有影响。

Description

本发明涉及一种预防或治疗动脉硬化的药物组合物和glimepiride用于制备这种组合物的应用。
动脉硬化一直被认为是由肥胖、高血压、血小板亢进、高脂肪血症、胰岛素过多症和吸烟等因素引起的。以前的动脉硬化治疗药包括高脂血症治疗药,如:mevalotin和抗血小板药物,如阿可匹林。这些药物的作用机制是通过抑制胆固醇合成中控速酶,HMG-CoA还原酶来降低血中胆固醇,或者通过抑制血小板环氧化酶来抑制血小板的聚集。尽管上面这些药物对治疗动脉硬化有效,但是人们一直希望能有一种更有效或者依赖于其它作用机制的动脉硬化治疗药。本发明有可能实现这个愿望。
本发明涉及一种能预防或治疗动脉硬化的药物组合物,它含有一种有效成份glimepiride,其属名为1-[4-(2-(3-乙基-4-甲基-2-氧代-3-吡咯啉-1-羧基酰胺基)乙基]-苯磺酰基]-3-(反-4-甲基环己基)-脲,如分子式(1),或者glimepiride的一种生理能接受的盐。
Figure 931212235_IMG3
本发明进一步涉及glimepiride或者其生理上能接受的盐用来制备这种组合物的应用。该组合物包括活性物质和如需要,可药用的填充剂,载体和/或赋形剂。
该组合物对预防和治疗脑动脉硬化,冠状动脉硬化和动脉硬化肾病特别有效。glimepiride是一种在EP-B-0031058(美国专利Nr.4,379,785)中描述的磺酸脲类药物(SU药),它被希望作为一种有效的非胰岛素依赖的糖尿病降血糖药。该药确定的药理作用包括刺激胰脏β细胞分泌胰岛素,加速葡萄糖在外周组织的吸收和抑制环氧化酶。然而其刺激胰岛素分泌作用比其它磺酰脲药物要温和。广泛研究的结果表明,我们发现glimepiride能抑制动脉粥性瘤在喂以高胆固醇食物的老鼠中的发展。基于这发现完成本发明。
Glimepiride成人每天给药1-32mg/人/天[大约0.01-0.5mg(以体得比)/kg/天]用于预防和治疗动脉硬化。
按照本发明,glimepiride或它的一种生理能接受的盐,可以采用口服,静脉注射,肌肉注射或其它方式给药,它可以采用片剂,糖衣片、丸剂、胶囊、粉剂、颗粒剂,栓剂或其它剂形服用。片剂对口服来说可能是最好的。例如:一个片子最好含有0.1-20mg,特别是0.5-1mg的glimepiride。Glimepiride或它的一种生理上能接受的盐可以与任何药用的填充剂混和,并可以按常规方法配制成上述任一剂形。
另外,glimepiride作为降血糖药已经对3000多个国内外病人给药。按上述剂量1-32mg/人/天给药时,此药无副反应,也无副作用。
精确的毒性试验结果如表1。

实施例1:
下面这些例子将举例说明glimipiride对动脉硬化的预防和治疗作用。
对喂以高胆固醇食物的兔子的动脉粥样硬化的预防和治疗作用。
对于10周大小的雄性新西兰属白兔,用含1%胆固醇的食物喂10周,以引起高胆固醇血症。一组8只兔,每天喂混有glimepiride0.1mg/kg/天的食物100g(8支兔作对照组)。剂量以人临床使用量为基础。血浆脂参数(总胆固醇、高密度脂蛋白(HDL)胆固醇、甘油三酯)和血浆胰岛素水平按予先设置的间隔测量。在给药期完成以后,为了测量位于血管内壁的主动脉硬化的损害,按照油红法(Lillie,R.D.(1944),stain    Technology,19卷,55页),把胸主动脉分离并染色。在胃排空时,放出血液,血浆离心分离用于测量脂肪含量。在喂以高胆固醇食物的兔中,图1为空腹时血浆总的胆固醇水平;图2为高密度脂蛋白胆固醇水平;图3为甘油三酯的水平。统计检验1学生试验)表明在给药组和对照组(非给药组)之间,对于血浆脂含量没有显著的差异。在喂以高胆固醇合物的兔中,表2为空腹血浆胰岛素水平,表3为位于血管壁的动脉硬化损伤的面积率。

表3

对照组:        -        57.50±7.13
给glimepiride组: 0.1 20.61±4.79**
**平均值±标准误差,P<0.01
图1中,对照组和给药组之间血浆脂含量没有区别,因此表明glinepiride对脂代谢没影响。表2中,服用glimepiride对空腹血浆水平没有看到有大影响。表3中,给药组和对照组相比,动脉硬化损伤的面积百分比有显著地降低。分析这些结果即在上述试验中,血浆脂含量和血浆胰岛素水平在对照组与给药组之间没有区别,glimepiride对动脉硬化的抑制作用,就不能认为是通过血清脂或者胰岛素起作用,它们可能是一个导致动脉硬化的危险因素,而应认为是通过其它的作用。
本发明的组合物因此用于预防或治疗动脉硬化,而对脂代谢没有影响,使空腹血浆胰岛素水平没有显著的增加。
实施例2(组合物)
使用10g    glimepiride,700g乳糖,40g玉米淀粉,5g聚乙烯吡咯烷酮,100g结晶纤维素,5g硬脂酸镁盐,按常规方法制成片剂,每片含有1mg的glimepiride。

图1为血液中总的胆固醇水平。
图2为血液中高密度脂蛋白胆固醇水平。
图3为血液中甘油三酯的水平。
