Summary
digoxin

Digoxin (Lanoxin) is a medicine that helps your heart pump better. It is used to treat heart failure and control irregular heartbeats.

nicardipine

Nicardipine is a drug that helps to lower blood pressure and treat chest pain. It belongs to a class of drugs called calcium channel blockers.

What It Treats
digoxin

Digoxin is used to treat mild to moderate heart failure in adults. It helps the heart pump more blood with each beat. Digoxin is also used in children with heart failure to help their heart work better. In adults, it can control a fast and irregular heartbeat called atrial fibrillation.

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
digoxin

Digoxin belongs to a class of drugs called cardiac glycosides. It works by making the heart muscle contract more strongly. It also slows down the electrical signals in the heart, which can help control irregular heartbeats.

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.

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, digoxin has 23,407 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. These two drugs have a known major interaction flagged in FDA labeling, attributed to nicardipine may cause digoxin to build up in your bloodstream by changing how your body handles the drug..
