This medicine is a blood thinner that helps prevent blood clots from forming. It is often used after surgery to prevent clots in the legs or lungs. It should be used during pregnancy only if necessary and with caution while breastfeeding.

Indications

Fondaparinux Sodium is a Factor Xa inhibitor (anticoagulant) indicated for:

Prophylaxis of deep vein thrombosis (DVT) in patients undergoing-
  • hip fracture surgery (including extended prophylaxis)
  • hip replacement surgery
  • knee replacement surgery or
  • abdominal surgery.
Treatment of Prophylaxis of deep vein thrombosis (DVT) or acute pulmonary embolism (PE) when administered in conjunction with warfarin.

Pharmacology

The antithrombotic activity of Fondaparinux Sodium is the result of selective inhibition of Factor Xa. By selectively binding to antithrombin III (ATIII), Fondaparinux Sodium potentiates (about 300 times) the innate neutralization of Factor Xa by ATIII. Neutralization of Factor Xa interrupts the blood coagulation cascade and thus inhibits thrombin formation and thrombus development. Fondaparinux Sodium does not inactivate thrombin (activated Factor II) and has no known effect on platelet function. At the recommended dose, Fondaparinux Sodium does not affect fibrinolytic activity or bleeding time.

Dosage & Administration

Important:
Do not take any medication without a doctor's prescription. Self-medication can be dangerous.
Prophylaxis of deep vein thrombosis:
  • Fondaparinux 2.5 mg subcutaneously once daily after hemostasis has been established.
  • The initial dose should be given no earlier than 6 to 8 hours after surgery and continued for 5 to 9 days.
  • For patients undergoing hip fracture surgery, extended prophylaxis up to 24 additional days is recommended.
Treatment of deep vein thrombosis and pulmonary embolism:
  • Fondaparinux 5 mg (body weight <50 kg)
  • Fondaparinux 7.5 mg (50 to 100 kg) or
  • Fondaparinux 10 mg (>100 kg) subcutaneously once daily.
Treatment should continue for at least 5 days until INR 2 to 3 achieved with warfarin sodium.

Pediatric Use: Safety and effectiveness of Fondaparinux Sodium in pediatric patients have not been established.

Geriatric Use: In clinical trials, the efficacy of Fondaparinux Sodium in the elderly (65 years or older) was similar to that seen in patients younger than 65 years; however, serious adverse events increased with age.

Use in renal or hepatic impairment: The risk of bleeding is increased with reduced renal or hepatic function.

  • Bleeding risk is increased in renal impairment and in patients with low body weight <50 kg
  • Consider the potential risks and benefits before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis
  • Thrombocytopenia can occur with administration of Fondaparinux Sodium
  • Periodic routine complete blood counts (including platelet counts), serum creatinine level and stool occult blood tests are recommended
