Nedocromil acts as a mast cell stabilizer, inhibits the degranulation of mast cells, prevents release of histamine and tryptase, so preventing the synthesis of prostaglandins and leukotrienes.
As a mast cell stabilizer, nedocromil prevents the release of substances that contribute to inflammation, such as histamine and tryptase, thereby reducing the production of inflammatory mediators like prostaglandins and leukotrienes.
