AGGRENOX is a combination antiplatelet agent intended for oral administration. Each hard gelatin capsule contains 200 mg dipyridamole in an extended-release form and 25 mg aspirin, as an immediate-release sugar-coated tablet. In addition, each capsule contains the following inactive ingredients: acacia, aluminum stearate, colloidal silicon dioxide, corn starch, dimethicone, hypromellose, hypromellose phthalate, lactose monohydrate, methacrylic acid copolymer, microcrystalline cellulose, povidone, stearic acid, sucrose, talc, tartaric acid, titanium dioxide and triacetin.
Each capsule shell contains gelatin, red iron oxide and yellow iron oxide, titanium dioxide and water.
AGGRENOX is indicated to reduce the risk of stroke in patients who have had transient ischemia of the brain or completed ischemic stroke due to thrombosis.

The study suggests that ambulances with the personnel and equipment capable of diagnosing ischemic stroke may be worth the extra cost, due to the decrease in patient disability afterward.
Published Studies Related to Aggrenox (Aspirin / Dipyridamole)
Use of aspirin associates with longer primary patency of hemodialysis grafts. [2011.04]
Extended-release dipyridamole plus low-dose aspirin (ERDP/ASA) prolongs primary unassisted graft patency of newly created hemodialysis arteriovenous grafts, but the individual contributions of each component are unknown. Here, we analyzed whether use of aspirin at baseline associated with primary unassisted graft patency among participants in a randomized trial that compared ERDP/ASA and placebo in newly created grafts.
Effects of Aggrenox and aspirin on plasma endothelial nitric oxide synthase and oxidised low-density lipoproteins in patients after ischaemic stroke. The AGgrenox versus aspirin therapy evaluation (AGATE) biomarker substudy. [2011.01]
Plasma endothelial nitric oxide synthase (eNOS), and oxidised low-density lipoproteins (oxLDL) are established biomarkers of atherosclerosis... In the small randomised study, both aspirin and Aggrenox produced fast and sustained recovery of plasma eNOS levels, while only therapy with Aggrenox was associated with oxLDL inhibition late in the trial.
The Japanese aggrenox (extended-release dipyridamole plus aspirin) stroke prevention versus aspirin programme (JASAP) study: a randomized, double-blind, controlled trial. 
BACKGROUND: Despite improvements in treatment, stroke still carries a high death toll and disability in Asia. Extended-release dipyridamole (ER-DP) plus acetylsalicylic acid (ASA) has consistently been shown to be superior over conventional platelet inhibition by ASA. ER-DP plus ASA is well established in the secondary prevention of stroke in a lot of countries including the USA and Europe. DP has an established benefit in the treatment of heart disease in Japan; however, for the prevention of stroke, the fixed-dose combination of ER-DP plus ASA has only been investigated in a small number of patients in Japan... CONCLUSIONS: The results of the study are inconclusive. Noninferiority of ER-DP plus ASA versus ASA could not be established, a difference between treatments could not be shown for the primary end point. Possible reasons for this result include a small sample size, low event rates and too short a treatment duration (ClinicalTrials. gov number, NCT00311402). Copyright (c) 2011 S. Karger AG, Basel.
Safety of fixed-dose aspirin-extended-release dipyridamole in patients with ischemic heart disease. [2010.05.01]
CONCLUSION: A literature review revealed that fixed-dose aspirin-ER dipyridamole was not associated with an increased risk of cardiovascular events in patients with ischemic heart disease. However, individual patient factors merit consideration when choosing an antiplatelet agent for stroke prevention.
Early treatment with aspirin plus extended-release dipyridamole for transient ischaemic attack or ischaemic stroke within 24 h of symptom onset (EARLY trial): a randomised, open-label, blinded-endpoint trial. [2010.02]
BACKGROUND: Little is known about the best antiplatelet treatment immediately after ischaemic stroke or transient ischaemic attack (TIA). The EARLY trial aimed to compare outcome in patients given aspirin plus extended-release dipyridamole twice daily either within 24 h of stroke or TIA or after 7 days of aspirin monotherapy... INTERPRETATION: Early initiation of aspirin plus extended-release dipyridamole within 24 h of stroke onset is likely to be as safe and effective in preventing disability as is later initiation after 7 days.
