Amlodipine-induced gingival hyperplasia.

Gingival hyperplasia can occur during use of drugs such as diphenylhydantoin, cyclosporine and nifedipine. We report, three cases of gingival hyperplasia induced by amlodipine, a second generation calcium channel blocker. Exact cause of induction of thehyperplasia is not known. Individual variation in metabolism of the drug may be a factor.
