A RECOGNIZED CAUSE OF BUCCAL APHTHOSIS: Nicorandil is the leading drug in a new pharmacology class of well tolerated anti-angina products with vasodilating action. The first cases of buccal aphthosis or ulcerations induced by nicorandil were reported in 1996. Among drugs inducing buccal aphthosis or ulcerations, the largest body of information available on reported cases concern nicorandil. ⋯ The lesions develop for about 3 to 36 before diagnosis and the delay to onset of signs after initiating nicorandil treatment is 15 days to 24 months (generally 2 months). Lesions basically develop after high-dose treatments and, for a few cases, after increasing the dosage. Cure is obtained in all cases after 1 to 12 weeks.
