title: Nicorandil associated anal ulceration.
abstract: OBJECTIVE
  Nicorandil is a vasodilator used to control angina. It has been associated with oral and anal ulceration that resolves upon withdrawal of the drug.
  
  
  METHODS
  We report a series of 13 patients with nonspecific anal ulceration all of whom were receiving nicorandil for control of symptoms of ischaemic heart disease.
  
  
  RESULTS
  All the ulcers had similar clinical and histological appearances. All the ulcers healed on withdrawal of the drug.
  
  
  CONCLUSIONS
  Nicorandil-associated anal ulceration should be considered in the differential diagnoses of nonhealing anal ulcers.
