Defibrotide sodium
What is Defibrotide sodium?[edit | edit source]
- Defibrotide sodium (Defitelio) is an oligonucleotide mixture with profibrinolytic properties used to treat hepatic veno-occlusive disease (a condition in which small veins in the liver are blocked) in patients who have kidney or lung problems after a stem cell transplant.
What are the uses of this medicine?[edit | edit source]
- This medicine is used for the treatment of adult and pediatric patients with hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), with renal or pulmonary dysfunction following hematopoietic stem-cell transplantation (HSCT).
How does this medicine work?[edit | edit source]
- The mechanism of action of defibrotide sodium has not been fully elucidated.
- In vitro, defibrotide sodium enhances the enzymatic activity of plasmin to hydrolyze fibrin clots.
- In vitro, defibrotide sodium increased tissue plasminogen activator (t-PA) and thrombomodulin expression, and decreased von Willebrand factor (vWF) and plasminogen activator inhibitor‑1 (PAI-1) expression, thereby reducing EC activation and increasing EC‑mediated fibrinolysis.
- Defibrotide sodium protected ECs from damage caused by chemotherapy, tumor necrosis factor-α (TNF-α), serum starvation, and perfusion.
Who Should Not Use this medicine ?[edit | edit source]
This medicine cannot be used in patients with:
- systemic anticoagulant or fibrinolytic therapy
- Known hypersensitivity to Defitelio or to any of its excipients
What drug interactions can this medicine cause?[edit | edit source]
- Concomitant use of Defitelio with antithrombotic or fibrinolytic drugs is contraindicated because of an increased risk of hemorrhage.
