Amlodipine-induced gingival hyperplasia in a Nepalese patient experiencing high dosages: a case report

Introduction and importance:Amlodipine is a third-generation calcium channel blocker used in the treatment of hypertension. One of the side effects associated with amlodipine is gingival hyperplasia mostly occurring at a higher dose (10 mg). There are very few cases of gingival hyperplasia associated with amlodipine at a lower dose (5 mg) or short-term administration.Case presentation:A 51-year-old male patient with diagnosed hypertension sought medical attention for gingival swelling and bleeding from the gums while brushing. He had been under amlodipine 5 mg for 12 months, which was increased to 10 mg for the last 2 months. The history and physical examination were consistent with amlodipine-induced gingival hyperplasia. The first line of treatment consisted of discontinuation of amlodipine and substitution with another class of anti-hypertensive.Clinical discussion and conclusion:The presented case highlights the challenge of balancing economic considerations with potential side effects in the use of amlodipine for hypertension in low-income countries like Nepal. Given its availability at no cost or minimal expense, amlodipine is often initiated as a first-line therapy. However, the decision to increase the dosage to 10 mg/day, influenced by economic constraints and the drug's affordability, raises the risk of gingival hyperplasia. This case emphasizes the importance of physicians being mindful of potential adverse effects when prescribing higher doses of amlodipine and underscores the need for continued vigilance in managing hypertension in resource-limited settings.
