General information

Class/mechanism: Recombinant factor VIIa; complexes with tissue factor and can activate coagulation factors X to Xa and IX to IXa, which results in conversion of prothrombin to thrombin, and fibrinogen to fibrin to form a fibrin clot. There is still uncertainty about the precise mechanism, and activation of factor X on platelet surfaces may also play an important role. Clinical applications include use for patients with inhibitors to factors VIII and IX, as can be the case in hemophilia A and hemophilia B. The NovoSeven RT formulation contains sucrose and L-Methionine which "allows the product to be stored at room temperature (up to 77 degrees Fahrenheit) for up to two years."[1][2][3][4]
Route: IV

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]
