Although oral steroids are effective in treating eosinophilic esophagitis, the side effects of orally-administered steroids limit their use. One new oral steroid that is being tested is budesonide , an orally-administered steroid that is absorbed into the body but is rapidly destroyed, resulting in fewer serious side effects. The current treatment of eosinophilic esophagitis is with swallowed (not inhaled) fluticasone propionate. Fluticasone propionate is a synthetic (man-made) steroid that is related to the naturally occurring steroid hormone, cortisol or hydrocortisone, produced by the adrenal glands. These steroids have potent anti-inflammatory actions. When used as an inhaler, fluticasone propionate reduces inflammation in the airways of patients with asthma , thus relieving wheezing and breathing difficulties. When fluticasone propionate is swallowed, it has been shown to reduce the eosinophils in the esophagus and relieve dysphagia in patients with eosinophilic esophagitis.
