Nicorandil-associated para-stomal ulceration: Case series.

Nicorandil is a vasodilator used to control severe angina. It has been associated with oral and anal ulceration that resolves upon withdrawal of the drug. We report a series of four patients, all of whom were receiving nicorandil therapy and developed nonspecific para-stomal ulcerations of similar clinical and histological appearance. All ulcers healed on withdrawal of nicorandil with no relapse. To the best of our knowledge, nicorandil-associated para-stomal ulcers have not been reported before. It is imperative to be aware of this association to prevent the persistence of these extremely painful ulcerations, and to avoid unnecessary and inappropriate interventions with substantial morbidity in a group of high-risk patients.
