Background:

Nedocromil suppresses the action or formation of multiple mediators, including histamine, leukotriene C4 (LTC4), and prostaglandin D2 (PGD2).

Nedocromil inhibits the release of histamine, LTC4, and PGD2 from mast cells challenged with antigen (with IC30 values of 2.1 μM, 2.3 μM, and 1.9 μM, respectively) and with anti-human IgE (IC30 values of 4.7 μM, 1.3 μM, and 1.3 μM, respectively)[1].

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[2].
