Interaksi Fondaparinuks dan Sulindak

…risk of developing epidural or spinal hematomas in these patients include: • use of indwelling epidural catheters • concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, or other anticoagulants • a history of traumatic or repeated epidural or spinal puncture • a history of spinal deformity…

The risk of these events may be higher with post-operative use of indwelling epidural catheters or concomitant use of other drugs affecting hemostasis such as NSAIDs [see Boxed Warning ] .

In clinical studies performed with fondaparinux sodium, the concomitant use of oral anticoagulants (warfarin sodium), platelet inhibitors (acetylsalicylic acid), NSAIDs (piroxicam), and digoxin did not significantly affect the pharmacokinetics/pharmacodynamics of fondaparinux sodium.

Other factors that increase the risk for GI bleeding in patients treated with NSAIDs include concomitant use of oral corticosteroids or anticoagulants, longer duration of NSAID therapy, smoking, use of alcohol, older age, and poor general health status.

However, patients should be monitored carefully until it is certain that no change in their anticoagulant dosage is required.

Oral anticoagulants Although sulindac and its sulfide metabolite are highly bound to protein, studies in which sulindac was given at a dose of 400 mg daily have shown no clinically significant interaction with oral anticoagulants.
