Oxybutynin-induced reflux esophagitis.

Oxybutynin has less anticholinergic activity than propantheline bromide. Therefore, oxybutynin is often preferentially prescribed for patients at risk of morbid complications of atropine-like adverse effects. We report a case of oxybutynin-induced reflux esophagitis. This probably resulted from the anticholinergic action of oxybutynin, which decreased lower esophageal sphincter tone. We outline a management approach for patients who experience this adverse effect due to oxybutynin or other commonly prescribed medications.
