Eosinophilic esophagitis is an allergic condition of the esophagus with an incidence that is on the rise, and has limited treatment options. Current gold standard of treatment is with topical steroids (swallowed fluticasone). There is preliminary data that oral montelukast may prove to be effective in inducing and maintaining symptomatic along with histologic remission of this disease. Investigators will be comparing the effectiveness of singulair to swallowed fluticasone in inducing and maintaining histologic and symptomatic remission of eosinophilic esophagitis.
