体外研究 |
西他生坦和波生坦在较高浓度下减弱NTCP转运,并抑制人肝转运蛋白,这为在临床环境中观察到的这些药物的肝毒性增加提供了潜在的机制。只有sitaxsentan减少了OATP转运(52%)[1]。西他生坦和西他生坦联合西地那非完全阻止内皮素-1和ETB受体的表达增加。单独的西他生坦可部分恢复BMPR-1A和BMPR-2的表达。西地那非和西他生坦的组合进一步恢复了BMPR-1A和BMPR-2的表达,然而,与对照组相比,BMPR-1A和BMPR-2的表达降低[3]。 |

体内研究 |
西他生坦(在缺氧发作前10分钟静脉注射5mg / kg)完全阻断缺氧诱导的血管收缩,该组与空气对照没有差异。西他生坦的口服给药显着减弱了MPAP的增加,而西他生坦对暴露于正常氧水平的大鼠的给药对MPAP没有影响[2]。西他生坦单独限制分流诱导的MT增加。西他生坦联合西地那非可以更有效地防止这种重塑,然而,与对照相比,这种重塑往往会增加[3]。 |

动物实验 |
在最初2周的低氧暴露期(10%O 2)后,在持续暴露于缺氧期间,给予西他生坦(在饮用水中每天15或30mg / kg体重)4周。在4周的缺氧期结束时,进行股动脉和肺动脉插管以及MPAP,MSAP和HR的测量。 |
