Aggrenox - General Information
A phosphodiesterase inhibitor that blocks uptake and metabolism of adenosine by erythrocytes and vascular endothelial cells. Aggrenox also potentiates the antiaggregating action of prostacyclin. (From AMA Drug Evaluations Annual, 1994, p752)
Pharmacology of Aggrenox
Aggrenox, a non-nitrate coronary vasodilator that also inhibits platelet aggregation, is combined with other anticoagulant drugs, such as warfarin, to prevent thrombosis in patients with valvular or vascular disorders. Aggrenox is also used in myocardial perfusion imaging, as an antiplatelet agent, and in combination with aspirin for stroke prophylaxis.
Aggrenox for patients
This medicine is sometimes called a "blood thinner". This medicine prevents blood clots form forming and may be given following a stroke or heart attack or for patient who have an irregular heart beat.

No pharmacokinetic drug-drug interaction studies were conducted with PERSANTINE® (dipyridamole USP) Tablets. The following information was obtained from the literature.
Adenosine: Dipyridamole has been reported to increase the plasma levels and cardiovascular effects of adenosine. Adjustment of adenosine dosage may be necessary.
Cholinesterase Inhibitors: Dipyridamole may counteract the anticholinesterase effect of cholinesterase inhibitors, thereby potentially aggravating myasthenia gravis.
Hypersensitivity to dipyridamole and any of the other components.
Additional information about Aggrenox
Aggrenox Indication: For as an adjunct to coumarin anticoagulants in the prevention of postoperative thromboembolic complications of cardiac valve replacement and also used in prevention of angina.
Mechanism Of Action: Aggrenox likely inhibits both adenosine deaminase and phosphodiesterase, preventing the degradation of cAMP, an inhibitor of platelet function. This elevation in cAMP blocks the release of arachidonic acid from membrane phospholipids and reduces thromboxane A2 activity. Aggrenox also directly stimulates the release of prostacyclin, which induces adenylate cyclase activity, thereby raising the intraplatelet concentration of cAMP and further inhibiting platelet aggregation.
Drug Interactions: Adenosine Increases the effect/toxicity of adenosine
Fludarabine Decreases the effect of fludarabine
Food Interactions: Take with food to reduce irritation.
Coffee and tea can decrease the effect of dipyridamole.
