Management of Amlodipine-Induced Gingival Enlargement

Introduction to Gingival Enlargement

• Amlodipine, a dihydropyridine calcium channel blocker (CCB), can cause gingival hyperplasia as a side effect, characterized by overgrowth of gingival tissue, which may present as diffuse gingival enlargement, localized gingival masses, or erythematous, sessile, soft tissue overgrowth, and alternative antihypertensive medications such as ACE inhibitors, ARBs, or beta-blockers should be considered to avoid this condition [1]

Alternative Antihypertensive Medications

• The British Journal of Dermatology recommends avoiding other dihydropyridine calcium channel blockers (nifedipine, felodipine) as they can also cause gingival hyperplasia, and substituting with another CCB like nifedipine may worsen the condition [1]
• The American Heart Association suggests considering medication interactions when switching antihypertensives, and being aware of potential interactions with other medications the patient may be taking, to ensure adequate blood pressure control is maintained during medication changes [2]

Surgical Treatment

• Surgical treatment alone is insufficient to manage amlodipine-induced gingival enlargement, as without addressing the underlying cause (medication), gingival enlargement will likely recur, and gingivectomy/gingivoplasty for removal of excess tissue, or periodontal flap surgery for complex cases, may be necessary [1]

Patient Management

• The American Journal of Kidney Diseases recommends recognizing that dihydropyridine CCBs can exacerbate proteinuria in patients with kidney disease, and these medications may increase protein excretion [3]
• Regular dental follow-up every 3-6 months, professional scaling and root planing to remove local irritants, and meticulous oral hygiene instructions to the patient are necessary to manage amlodipine-induced gingival enlargement [1]

Medication Management

• If amlodipine cannot be discontinued due to medical necessity, consider dose reduction (if possible), even reducing to 2.5mg daily has shown resolution of gingival masses, and implement more frequent professional dental cleaning (every 2-3 months) [1]
• Twice daily brushing with soft toothbrush, daily interdental cleaning (floss, interdental brushes), and chlorhexidine mouthwash (0.12%) twice daily for 2 weeks to reduce inflammation are recommended for patients with amlodipine-induced gingival enlargement [1]
