From the Guidelines
Combining cilostazol with apixaban and aspirin is not recommended due to the increased risk of bleeding, as evidenced by the 2024 ESC guidelines for the management of atrial fibrillation 1. The use of multiple antithrombotic agents, including antiplatelet drugs and anticoagulants, can lead to an excessive antiplatelet and anticoagulant effect, resulting in dangerous bleeding complications. Key points to consider include:
- The mechanism of action of each medication: cilostazol inhibits platelet aggregation, apixaban is a direct factor Xa inhibitor anticoagulant, and aspirin irreversibly inhibits platelet function.
- The increased risk of bleeding associated with combination therapy, as noted in the 2024 ESC guidelines 1.
- The importance of careful consideration of the bleeding risk versus thrombotic risk, as well as close specialist supervision and regular monitoring for bleeding signs. Some studies suggest that combining antiplatelet drugs with anticoagulants may not provide a clear benefit in terms of prevention of stroke or death, and may instead increase the risk of bleeding events 1. In general, the combination of antiplatelet drugs with anticoagulants should only occur in selected patients with acute vascular disease, and under close specialist supervision. Patients should be educated about bleeding symptoms to watch for, including unusual bruising, nosebleeds, blood in urine or stool, and severe headaches, as noted in the guidelines 1.
From the FDA Drug Label
Concomitant use of drugs affecting hemostasis increases the risk of bleeding. These include aspirin and other antiplatelet agents, other anticoagulants, heparin, thrombolytic agents, selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and nonsteroidal anti-inflammatory drugs (NSAIDs)
The FDA drug label does not provide information about the concomitant use of cilostazol with apixaban and aspirin. However, it does mention that concomitant use of drugs affecting hemostasis, such as aspirin and other antiplatelet agents, increases the risk of bleeding.
- Key points:
- Aspirin and other antiplatelet agents increase the risk of bleeding when used with apixaban.
- Cilostazol is an antiplatelet agent.
- The label does not provide direct information about the use of cilostazol with apixaban and aspirin. Given the lack of direct information, no conclusion can be drawn about the safety of administering cilostazol with apixaban and aspirin 2.
From the Research
Administration of Cilostazol with Apixaban and Aspirin
- The provided studies do not directly address the administration of cilostazol with apixaban and aspirin together 3, 4, 5, 6, 7.
- However, studies have investigated the use of cilostazol with aspirin, showing that coadministration does not result in clinically significant changes to coagulation parameters, bleeding time, or platelet aggregation 4.
- Additionally, a study compared triple antiplatelet therapy with cilostazol to dual antiplatelet therapy with standard or potent P2Y12 inhibitors, finding that the triple therapy was associated with an improved net clinical outcome without increasing the risk of bleeding 5.
- Another study investigated the efficacy and safety of dual antiplatelet therapy using cilostazol and aspirin in noncardioembolic stroke patients, finding that the dual therapy was safe but did not reduce the rate of short-term neurological worsening 6.
- A network meta-analysis compared the efficacy and safety of different antiplatelet or anticoagulation drugs, including aspirin, clopidogrel, and rivaroxaban, but did not specifically address the combination of cilostazol, apixaban, and aspirin 7.
- Overall, while there is limited direct evidence on the administration of cilostazol with apixaban and aspirin, the available studies suggest that cilostazol can be safely used with aspirin, and its use in combination with other antiplatelet agents may be beneficial in certain clinical contexts 3, 4, 5, 6, 7.
