General information
Class/mechanism: Profibrinolytic. Defibrotide is a mixture of polydeoxyribonucleotide sodium salts made from porcine intestinal tissue. In vitro, it boosts enzymatic activity of plasmin to hydrolyze fibrin clots. Defibrotide increases tissue plasminogen activator (t-PA) and thrombomodulin expression while decreasing von Willebrand factor (vWF) and plasminogen activator inhibitor-1 (PAI-1) expression. Endothelial cell fibrinolysis is enchanced and endothelial cell activation is reduced. Defibrotide appears to limit damage caused by chemotherapy, tumor necrosis factor-α (TNF-α), serum starvation, and perfusion.[1][2][3]
Route: IV
Extravasation: no information
For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]
