説明
Fondaparinux sodium was first introduced in the US for prophylaxis of deep vein
thrombosis which may lead to pulmonary embolism following major orthopaedic surgery.
Fondaparinux is the first of a new class of antithrombic agents distinct from low molecular
weight heparin (LMWH) and heparin. This entirely synthetic molecule is a copy of the
heparin pentasaccharide sequence, the shortest fragment able to catalyze antithrombin lllmediated
inhibition of factor Xa thereby inhibiting thrombin generation without antithrombin
action. Fondaparinux does not display significant effects on coagulation tests (such as activated partial thromboplastin time and prothrombin time), does not bind to platelet factor
4 or promote heparin-induced thrombocytopenia. In phase III studies, fondaparinux
significantly reduced the incidence of thromboembolism following orthopedic surgery, with
an overall risk reduction of 50% in comparison to the LMWH, enoxaparin. Following
subcutaneous administration, fondaparinux has a nearly complete bioavailability, a rapid
onset of action, a prolonged half-life (17.2 h) enabling once daily dosing and is not
metabolized preceeding renal excretion. The drug appears to be generally safe, with
haemoragic complications either comparable to or higher than those for LMWH.
化学的特性
White Powder (after lyophilisation)
使用
Fondaparinux sodium has been used to test its neutralizing effect towards enterovirus D68-947 infection. It may be used in ultraviolet photodissociation (UVPD) measurements.
適応症
Fondaparinux sodium injection 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 DVT or acute pulmonary embolism (PE) when administered in conjunction with warfarin.
定義
ChEBI: An organic sodium salt, being the decasodium salt of fondaparinux.
副作用
Fondaparinux sodium is a prescription medication and as such, most people do not have serious side effects. However, pain, bruising, redness, and swelling at the injection site may occur, as well as headache, nausea, vomiting, swelling of the hands and feet, or fever.
A few serious side effects may occur: easy bleeding or bruising; dark urine, yellowing of the eyes or skin; shortness of breath, coughing up blood, chest pain, unusual dizziness, fainting, fast or irregular heartbeat; joint or muscle pain; confusion. Very few patients may experience allergic reactions (e.g. rash, itching or swelling (especially on face/tongue/throat); severe dizziness, difficulty breathing).
