Nedocromil
Nedocromil sodium is a medication considered as mast cell stabilizer which act to prevent wheezing, shortness of breath, and other breathing problems caused by asthma. It is administered by an inhaler under the brand name Tilade (although its effects in this form are far less than those in albuterol or other well-known inhaler medications) and as an eye drop under the brand name Alocril.[1][2] Liquid preparations are available in the UK under the name Rapitil for use for allergic eye reactions.[3] Nedocromil sodium has been shown to be effective in alleviating symptoms of allergic conjunctivitis.[4]

Nedocromil is classified as a benzopyrone. 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. US Production of inhaled nedocromil ceased in April 2008.[5]
