Quixidar is a solution for injection in a prefilled syringe.
Quixidar contains the active substance fondaparinux sodium (1.5, 2.5, 5, 7.5 or 10 mg per syringe).
problems caused by blood clots) in patients who are having major surgery to their legs, such as a hip replacement or surgery to repair a knee or hip fracture. It can also be used in patients at high risk (because of their age or disease) when they have abdominal surgery, especially for cancer, or when they are forced to stay in bed because of an acute illness.
At higher strengths (5, 7.5 and 10 mg), Quixidar is used to treat VTEs such as deep vein thrombosis (DVT, a blood clot in the leg) or pulmonary embolism (PE, blood clot in the lung).
The 2.5 mg strength is also used to treat patients with unstable angina (a type of chest pain that changes in severity) or who are having a myocardial infarction (heart attack):
• without ‘ST segment elevation’ (an abnormal reading on the electrocardiogram or ECG) in
or who are not about to receive any other treatment to restore blood flow to the heart. The medicine can only be obtained with a prescription.

How is Quixidar used?
In the prevention of VTEs, the recommended dose of Quixidar is 2.5 mg once a day by subcutaneous injection (under the skin). For patients having surgery, the first dose should be given six hours after the end of the operation. Treatment should be continued until the risk of VTE has been reduced, usually at least five to nine days after surgery. For patients who have kidney problems, Quixidar may not be suitable, or the lower
injection, usually for seven days. The dose may be adjusted, depending on body weight.
For patients with unstable angina or myocardial infarction, the recommended dose is 2.5 mg once daily by subcutaneous injection, but the first dose is given intravenously (into a vein) through an existing line or as an infusion (drip) in patients with ST segment elevation. Treatment should be
started as soon as possible after diagnosis and continued for up to eight days or until the patient is discharged from hospital. Quixidar is not recommended in patients who are about to undergo certain types of PCI.

How does Quixidar work?
Blood clotting can be a problem when blood flow is disturbed in any way. Quixidar is an

anticoagulant; it prevents the blood from coagulating (clotting). The active ingredient in Quixidar, fondaparinux sodium, stops one of the substances (factors) that are involvedauthorisedin the clotting of blood, Factor Xa. When this is blocked, no thrombin (another factor) can be produced, and no clot can be
reducing blood clots, Quixidar can also help the flow of blood to the heart to be maintained in patients with angina or who are having a heart attack.
How has Quixidar been studied?
The effectiveness of Quixidar has been studied for the prevention of and in the treatment of VTE. In
the prevention studies, Quixidar was compared with other anticoagulants: enoxaparin (in hip or knee surgery; over 8,000 patients) or dalteparin (in abdominal surgery; 2,927 patients). It was also
compared with placebo (a dummy treatment) when looking at patients with an acute illness (839
patients) and patients treated for an additional 24 days following hip fracture surgery (656 patients). In

The overall rate of thrombotic events in patients treated with Quixidar was significantly less than in patients treated with placebo or enoxaparin (for patients undergoing leg surgery), and was similar to that seen with enoxaparin (treatment of DVT), dalteparin or unfractionated heparin.
Quixidar was at least as effective as enoxaparin in preventing death or an ischaemic event in patients with unstable angina or myocardial infarction without ST segment elevation, with around 5% of the patients in each group had died or had an ischaemic event after nine days. In the study of myocardial
infarction with ST segment elevation, Quixidar reduced the risk of death or another heart attack by
Medicinal14% after 30 days, compared to standard care. However, these results were insufficient to show whether Quixidar was more effective than unfractionated heparin or not.
What is the risk associated with Quixidar?
As with other antithrombotic medicines, the most common side effect of Quixidar is bleeding. For the full list of all side effects reported with Quixidar, see the Package Leaflet.
Quixidar should not be used in people who may be hypersensitive (allergic) to fondaparinux sodium or any of the other ingredients, who might be bleeding already, who have acute bacterial endocarditis (an infection of the heart) or have severe kidney problems. For the full list of restrictions, see the Package Leaflet.
Why has Quixidar been approved?
The Committee for Medicinal Products for Human Use (CHMP) decided that Quixidar’s benefits are greater than its risks in both the prevention and the treatment of VTEs, unstable angina and myocardial infarction. The Committee recommended that Quixidar be given marketing authorisation.
