奈多罗米钠 用途与合成方法
本类药物包括炎症细胞膜稳定剂，如色甘酸钠，奈多罗米钠以及H1受体阻断剂如酮替芬，白三烯药阻断药半胱氨酰白三烯等；通过抑制免疫球蛋白E介导的肥大细胞释放介质和对抑制巨噬细胞、嗜酸性粒细胞、单核细胞等炎症细胞的活性发挥抗过敏作用和轻度的抗炎作用。其平喘作用起效较慢，不宜用于哮喘急性发作期的治疗，临床上主要用于预防哮喘的发作。 Nedocromil sodium 抑制多种介质的作用或形成，包括组胺，白三烯 C4 (LTC4) 和前列腺素 D2 (PGD2)。

Nedocromil inhibits the release of histamine, LTC 4 , and PGD 2 from mast cells challenged with antigen (with IC 30 values of 2.1 μM, 2.3 μM, and 1.9 μM, respectively) and with anti-human IgE (IC 30 values of 4.7 μM, 1.3 μM, and 1.3 μM, respectively).
Nedocromil-treated diabetic mice show significantly improved heart function compared with controls. The contractility and relaxation forces show similar improvements. However, the cardiac function of Nedocromil-treated diabetic mice remains significantly impaired when compared with normal mice. Nedocromil can significantly improve cardiac function in mice with diabetic cardiomyopathy, but the treatment cannot restore normal function.
