What It Treats
felodipine

nicardipine

Nicardipine treats chronic stable angina, which is chest pain that happens when you exert yourself. It can be used alone or with beta-blockers to manage this condition. Nicardipine also treats high blood pressure, and it can be used alone or with other blood pressure medications.

How It Works
felodipine

Felodipine is a calcium channel blocker. It works by relaxing and widening your blood vessels. This makes it easier for blood to flow, which lowers blood pressure.

nicardipine

Nicardipine works by blocking calcium from entering certain cells in your heart and blood vessels. This helps to relax and widen your blood vessels, which lowers blood pressure. It also reduces the workload on your heart, which can help to relieve chest pain.

How to Read This felodipine vs nicardipine Comparison

felodipine is classified in the Calcium Channel Blocker drug class, while nicardipine sits within the Calcium Channel Blocker class. Because both drugs share the same classification, they are often considered interchangeable in theory, but clinical outcomes rarely track that cleanly. Both drugs are prescription-only, so a licensed provider must authorize use.

Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, felodipine has 4,641 submissions while nicardipine has 972. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. No direct interaction between these two drugs is listed in our FDA-derived dataset, though co-prescription still warrants pharmacist review. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.

A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for felodipine or nicardipine.
