Dipyridamole is indicated in Prophylaxis of thromboembolism following cardiac valve replacement, Secondary prophylaxis of stroke or transient ischaemic attack


Dipyridamole causes an accumulation of adenosine, adenine nucleotides and cAMP by inhibiting the activity of adenosine deaminase and phosphodiesterase thus inhibiting platelet aggregation and may cause vasodilation.


Prophylaxis of thromboembolism following cardiac valve replacement:
  • Adult: 300-600 mg/day in divided doses with an oral anticoagulant.

Secondary prophylaxis of stroke or transient ischaemic attack:
  • Adult: As modified-release preparation: 200 mg bid, with or without aspirin.
