药效药理
作用机序
1.支气管哮喘
孟鲁司特是选择性地结合到半胱氨酰白三烯受体1（半胱氨酸LT1受体），LTD 4和LTE 4的病理生理作用是炎症介质引起（支气管收缩，增加血管通透性，和粘液分泌压制推广）。基于这种作用机理，孟鲁司特作为抗哮喘作用，改善哮喘炎症的各种因素。
2.过敏性鼻炎
在过敏性鼻炎，抗原激发后，半胱氨酰白三烯从鼻粘膜中任何立即相和Osohatsusho的释放。其释放与过敏性鼻炎的症状。此外，白三烯胱鼻内给药增加了鼻气流阻力，已经显示出恶化鼻闭症状。孟鲁司特通过阻断白三烯受体的作用，已经建议在缓解过敏性鼻炎的症状可发挥重要的作用。
LT受体拮抗剂（受体结合试验）
受容体結合試験（モルモット肺細胞膜、U937細胞膜及びTHP-1細胞膜）で、LTD4の受容体結合を強力に阻害し、その作用は血液成分による影響を受けなかった。LTC4及びLTB4に対する受容体拮抗作用は弱かった。
支气管收缩抑制作用（孤立的器官和动物研究）
LTD4在豚鼠离体气管收缩是竞争性抑制。此外，它表现出对豚鼠和松鼠猴LTD4引起的支气管收缩反应强烈和持久的抑制作用。另一方面，孟鲁司特没抑制LTC 4（即抑制LTC 4的代谢条件）的切除的组织的收缩。此外，使用豚鼠，花生四烯酸，支气管收缩羟色胺和乙酰胆碱诱导的组胺难以抑制。
由抗原诱导的支气管收缩的抑制动作
哮喘大鼠致敏，由抗原诱导的豚鼠和松鼠猴支气管收缩反应是由静脉注射和口服给药抑制。在临床试验中海外，75％直接与抗原施用和晚期的支气管收缩，分别为57％的抑制。
对速发型和迟发型反应的支气管收缩抑制作用
由抗原诱导致敏松鼠猴的直接和延迟的支气管收缩反应通过口服给药抑制。
针对过敏性休克的抑制作用
过敏性休克是由于致敏豚鼠卵白蛋白部分抑制。
鼻气流阻力增加（鼻塞）通过抗原诱导的抑制效果
使用致敏豚鼠，在鼻气流阻力的增加引起的卵清蛋白吸入（鼻塞），孟鲁司特1和3毫克/公斤（腹腔给药）为55％，分别表现出85％的抑制作用。
改善肺功能的作用
在慢性支气管哮喘患者轻至中度，并在1秒内提高音量和呼气峰流速。
嗜酸性粒细胞上的作用
在慢性支气管哮喘患者轻，中度，有人显著与痰安慰剂嗜酸性粒细胞比例相比减少。同样，成年人，外周血嗜酸细胞比例也显著在儿科患者减少了。
适应病症
