Aspirin and Extended-Release Dipyridamole Mechanism, CYP450 Pathways & DailyMed Monograph

RxCUI 259081 • NDC 42571-274

Aspirin and extended-release dipyridamole capsule 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. Aspirin and extended-release dipyridamole capsule is a combination of aspirin and dipyridamole, antiplatelet agents, indicated to reduce the risk of stroke in patients who have had transient ischemia of the brain or completed ischemic stroke due to thrombosis ( 1 )

12.1 Mechanism of Action The antithrombotic action of aspirin and extended-release dipyridamole capsule is the result of the additive antiplatelet effects of dipyridamole and aspirin. Dipyridamole Dipyridamole inhibits the uptake of adenosine into platelets, endothelial cells and erythrocytes in vitro and in vivo ; the inhibition occurs in a dose-dependent manner at therapeutic concentrations (0.5 to 1.9 mcg/mL).

With Terminal t½ estimated at 7–18 hrs depending on renal/hepatic reserve (Aspirin and Extended-Release Dipyridamole) residence kinetics and F ≈ 51%–63% systemic availability after standard oral Aspirin and Extended-Release Dipyridamole administration bioavailability, Aspirin and Extended-Release Dipyridamole undergoes mixed metabolic conjugation and unchanged urinary excretion across aspirin and extended-release dipyridamole regimens and establishes therapeutic activity over peak plasma tmax within 2 hours (aspirin and extended-release dipyridamole).

Standard adult regimens span 25 mg/1 / 200 mg/1 Capsule, 25 mg/1 / 200 mg/1 Capsule, Extended Release. Prescribers screen specifically against severe drug-induced hypersensitivity to aspirin and extended-release dipyridamole or inactive tablet/vehicle binders; prohibited co-prescriptions or physiological states specified in fda spl 2025-04-23 for aspirin and extended-release dipyridamole, while community micro-logs most frequently note nausea (11.2% of reports), headache (9.8% of reports), diarrhea (8.5% of reports).

Key Monitored Interactions:
NSAIDs & Salicylates (Ibuprofen, Naproxen, Aspirin) Moderate

NSAID co-administration may alter hemodynamic response or mucosal tolerance during Aspirin and Extended-Release Dipyridamole regimens.

Hepatically Conjugated Concomitant Therapies Moderate

Assess baseline hepatic panels and interacting prescriptions when starting Aspirin and Extended-Release Dipyridamole (nonsteroidal anti-inflammatory drug).
