Nedocromil is considered to be more effective in treating asthma compared to a placebo.
Nedocromil is a mast cell stabilizer and anti-inflammatory and anti-allergic drug. Nedocromil inhibits the degranulation of mast cells, and prevents the activation of and mediator release from a variety of inflammatory cell types. Nedocromil inhibits release of histamine, leukotriene C4, and prostaglandin D2, but has no antihistamine, bronchodilator, or corticosteroid activity itself.
