A patient on amlodipine presents with generalized gingival overgrowth. The most likely cause is:
Show answer and explanation
Correct answer: A. Medication-induced (calcium channel blocker)
- A. Correct. Amlodipine is a calcium channel blocker — one of the three classic drug classes (with phenytoin and cyclosporine) causing gingival enlargement.
- B. Plaque worsens drug-induced overgrowth but is not the primary cause here.
- C. Hormonal overgrowth (e.g., pregnancy) doesn't fit a patient on amlodipine.
- D. Leukemic enlargement is possible but far less likely than the obvious CCB association.
