Side-by-side comparison of adenosine and dipyridamole. Data from FDA drug databases (Orange Book, NDC Directory, recalls, shortages) covering 20,000+ approved drugs, plus CMS pricing; see our methodology.
minor Known Drug Interaction
Adenosinergic agents (e.g., adenosine, regadenoson) Dipyridamole has been reported to increase the plasma levels and cardiovascular effects of adenosine. Adjustment of adenosine dosage may be necessary. Dipyridamole also increases the cardiovascular effects of regadenoson, an adenosine A 2A -receptor agonist.
Adenocard
Persantine
Adenosine (Adenocard) is a medicine used to treat certain types of irregular heartbeats. It belongs to a class of drugs called antiarrhythmics.
Dipyridamole helps prevent blood clots after heart valve replacement. It works with other blood-thinning medicines.
Adenosine is used to treat a very fast heart rate in the upper chambers of your heart. This condition is called supraventricular tachycardia (SVT). Adenosine helps to slow down your heart rate to a normal rhythm.
This medicine helps prevent blood clots after you have a heart valve replaced. It is used with a medicine like warfarin to prevent problems with blood clots. Dipyridamole does not work by itself for this purpose.
Adenosine works by slowing down the electrical signals in your heart. This helps to interrupt the fast heart rhythm and restore a normal heartbeat. It does this by acting on specific receptors in the heart tissue.
Dipyridamole is an antiplatelet medicine. It helps to keep blood cells called platelets from sticking together and forming clots. This helps your blood flow more freely.

Since this medication is administered by a healthcare provider in a monitored setting, there are no specific at-home warnings.
Taking dipyridamole with certain medicines used for heart stress tests can increase the risk of heart-related side effects. Make sure your doctor knows you are taking dipyridamole before any stress test.

How to Read This adenosine vs dipyridamole Comparison
adenosine is classified in the Endogenous Nucleoside (Antiarrhythmic) drug class, while dipyridamole sits within the Antiplatelet / Vasodilator class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. 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, adenosine has 399 submissions while dipyridamole has 2,560. 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 minor interaction flagged in FDA labeling, attributed to dipyridamole causes adenosine levels to build up in the blood, which can make the effects on your heart and blood vessels stronger.. 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 adenosine or dipyridamole.
