Abstract
本发明是关于α1L-激动剂在治疗尿失禁中的用途。
Description
本发明是关于α1L-激动剂在治疗尿失禁,特别是压迫性尿失禁中的用途。
妇女的压迫性尿失禁通常是由骨盆底部衰弱所引起,例如多次难产后。然而,也可归因于骨盆底部的神经病变、先天性尿道短小或有时因手术导致括约肌损伤。停经后,雌激素减少更会加速压迫性尿失禁。
压迫性尿失禁一词是指突发性的尿液流失,它是由于咳嗽、挤压、喷嚏、重举等等,导致腹内压力增加而造成膀胱缓慢移动时的膀胱出口闭锁不全。

上述化合物的优点之一在于其主要作用于尿道且对心脏血管系统有极少或毫无影响。
根据本发明化合物的选择性药物活性是由实施例2化合物2-(6-溴-3-二甲氨基-2-甲苯亚氨基)-咪唑烷和对照化合物苯肾上腺素,经由测量兔子尿道的管腔内压和血压而加以说明。
雌性日本白兔(重3.0至35公斤)以尿烷麻醉(1克/公斤腹膜内注射)后。通过小切口在膀胱插入聚乙烯套管。并通过在尿道内含37℃的1.5毫升水的气球,记录管腔内压的变化。官腔内压以压力-电压转换器记录在多路描记器上。
切开颈部并在颈动脉插入套管以测量血压,同时,为了保持呼吸,在气管插入套管。以压力-电压转换器在多路描记器上记录血压的变化。而心跳速率则以血流速计测量。
将苯肾上腺素和实施例2化合物用静脉注射法,经聚乙烯套管注入股静脉。比较30微克/公斤剂量的苯肾上腺素和10微克/公斤实施例2化合物。
与苯肾上腺素比较,本发明实施例2化合物在尿道收缩上具有的效力高2.73因数,且在效力持续上加长4.3因数。通过比较,本发明化合物所提高的血压仅为对照化合物苯肾上腺素的1.39倍。应注意,与苯肾上腺素比较血压提高现象仅延长不明显的程度(1.17因数)。这些实验表示,本发明化合物对尿道有选择性作用。本发明化合物是选择性α1L-肾上腺素能受体激动剂,它适于治疗尿失禁,特别是治疗压迫性尿失禁。
测试结果列于表1。表1
