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.
