Implication
May warrant caution with ibuprofen plus aspirin; leaves open effects on cardiovascular outcomes.
Key Points
- This study aims to evaluate how cyclooxygenase inhibitors, particularly ibuprofen, influence the antiplatelet effects of aspirin.
- Concomitant administration of ibuprofen and aspirin evaluated for its effects on platelet inhibition.
- Comparison of ibuprofen with rofecoxib, acetaminophen, and diclofenac in antagonizing aspirin's effects.
- Ibuprofen significantly antagonizes the irreversible platelet inhibition caused by aspirin.
- Rofecoxib, acetaminophen, and diclofenac do not affect aspirin's platelet inhibition.
- Ibuprofen treatment potentially limits aspirin's cardioprotective effects in patients at increased cardiovascular risk.
Structured PICO

P
Population
Patients with increased cardiovascular risk taking aspirin
I
Intervention
Concomitant administration of ibuprofen, rofecoxib, acetaminophen, or diclofenac
O
Outcome
Irreversible platelet inhibition induced by aspirinsurrogate
Concomitant use of ibuprofen may limit the cardioprotective effects of aspirin by antagonizing its antiplatelet activity.
