Dipyridamole Oral, Intravenous and Orfadin

• Generic Name: dipyridamole
• Dosage Forms: n.a.
• Other Brand Names: Persantine, Persantine IV

Dipyridamole is used to lessen the chance of stroke or other serious medical problems that may occur when a blood vessel is blocked by blood clots. It is given only when there is a larger-than-usual chance that these problems may occur. For example, it is given to people who have had diseased heart valves replaced by mechanical valves, because dangerous blood clots are especially likely to occur in these patients. Dipyridamole works by helping to prevent dangerous blood clots from forming.

Dipyridamole may also be used for other heart and blood conditions as determined by your doctor.

Dipyridamole is also sometimes used as part of a medical test that shows how well blood is flowing to your heart.

Dipyridamole is available only with your doctor's prescription.

Orfadin works by preventing the body from breaking down an amino acid called tyrosine and by keeping other toxic substances from building up and causing harm to your liver or kidneys.

Orfadin is used to treat a rare genetic condition called hereditary tyrosinemia type 1 (HT-1). HT-1 is a metabolic disorder that occurs when the body does not produce enough of an enzyme that breaks down proteins from certain foods. This condition occurs most often in young babies.

Orfadin may also be used for purposes not listed in this medication guide.
