Gingival hyperplasia caused by nifedipine--a preliminary report
International Journal of Cardiology
|February 1, 1984
Summary
Nifedipine, a calcium channel blocker, may cause gingival hyperplasia, a condition characterized by gum overgrowth. This side effect is similar to that seen with other medications like Dilantin, suggesting a potential drug-induced mechanism.
Area of Science:
- Oral medicine
- Pharmacology
- Histopathology
Background:
- Gingival hyperplasia is a known side effect of certain medications, notably antiepileptic drugs like phenytoin (Dilantin).
- Calcium channel blockers are widely prescribed for cardiovascular conditions.
- Understanding drug-induced gingival overgrowth is crucial for patient management.
Observation:
- Five patients treated with nifedipine developed marked gingival hyperplasia over 18 months.
- Clinical and histological features of the observed hyperplasia mimicked that of Dilantin-induced gingival overgrowth.
- Biopsy specimens consistently showed epithelial hyperplasia (acanthosis) and lamina propria inflammation.
Findings:
- A strong association between nifedipine administration and the development of gingival hyperplasia was identified.
- Histological analysis revealed significant epithelial thickening and inflammatory responses in the gum tissue.
- The findings suggest nifedipine as a potential causative agent for drug-induced gingival hyperplasia.
Implications:
- Clinicians should be aware of the potential for nifedipine to cause gingival hyperplasia.
- Monitoring patients on nifedipine for signs of gingival overgrowth is recommended.
- This observation may prompt further research into the mechanisms of calcium channel blocker-induced gingival hyperplasia.
