To obtain Defitelio (defibrotide sodium), a prescription is required from a healthcare professional. Defitelio is a medication used to treat severe hepatic veno-occlusive disease (VOD), also known as sinusoidal obstruction syndrome (SOS), in hematopoietic stem cell transplant (HSCT) conditioning regimens [1].
What is Defitelio prescribed for?
Defitelio is indicated for adult and pediatric patients who develop severe hepatic VOD with VOD/SOS and new-onset or worsening renal or pulmonary dysfunction [1]. It is crucial for patients to be diagnosed by a physician experienced in treating VOD/SOS [2].
How is Defitelio administered?
Defitelio is administered intravenously. It is typically given as a continuous infusion over at least two hours every six hours [3]. The dosage is based on body weight [3].
What are the potential side effects of Defitelio?
Common side effects associated with Defitelio include diarrhea, nausea, vomiting, and hypokalemia. Less common but serious side effects can include bleeding events, hypersensitivity reactions, and hypertension [4]. Patients should report any unusual bleeding or bruising to their healthcare provider immediately [4].
How does Defitelio work?
The exact mechanism of action for defibrotide sodium is not fully understood. However, it is believed to have anticoagulant, anti-inflammatory, and anti-ischemic properties. It may help restore the balance between pro-thrombotic and anti-thrombotic factors on the vascular endothelium, which is disrupted in VOD/SOS [5]. Defitelio is thought to improve fibrinolysis and inhibit platelet aggregation, thus helping to resolve clots in the hepatic sinusoidal vessels [5].
Where can I find more information about Defitelio?
Detailed prescribing information, including indications, dosage, administration, warnings, and precautions, is available from the manufacturer and through medical resources such as the FDA's website [1][3]. Patients should discuss any questions or concerns about Defitelio with their prescribing physician or a qualified healthcare provider.
Who manufactures Defitelio?
Defitelio is manufactured by Jazz Pharmaceuticals [6].
What is the cost of Defitelio?
The cost of Defitelio can vary significantly based on factors such as dosage, duration of treatment, insurance coverage, and geographic location. It is a high-cost medication often administered in a hospital or specialized clinic setting. Patients are encouraged to discuss financial assistance programs and insurance coverage options with their healthcare provider and the manufacturer [6].
Are there any alternatives to Defitelio for VOD/SOS?
Treatment for severe VOD/SOS is complex, and Defitelio is a primary treatment option. Supportive care, including fluid management and management of organ dysfunction, is also critical. In some cases, other agents might be considered depending on the specific clinical situation and physician's judgment, but Defitelio is the approved therapy for severe VOD/SOS with organ dysfunction [1][2].
What clinical data supports Defitelio's use?
Defitelio's approval was based on clinical studies demonstrating its efficacy and safety in treating severe VOD/SOS. These studies evaluated its impact on survival and the resolution of organ dysfunction in patients who underwent HSCT [1][5].
What are the risks associated with Defitelio treatment?
The main risks associated with Defitelio include bleeding, particularly in patients who are also receiving anticoagulant therapy. Hypersensitivity reactions can occur, and blood pressure should be monitored due to the risk of hypertension [4].
