What is recombinant activated factor VII?
Recombinant activated factor VII (rFVIIa; Novo Nordisk, Bagsvaerd, Denmark) is a hemostatic agent originally developed for the management of bleeding in haemophilia A and B patients with inhibitors to factor VIII or IX respectively.
What is VIIa?
Coagulation factor VIIa is a man-made protein similar to a natural protein in the body that helps the blood to clot. Coagulation factor VIIa is used to treat or prevent bleeding in people with hemophilia A or hemophilia B, or factor VII deficiency.
What is the difference between NovoSeven and NovoSeven RT?
The new NovoSeven RT provides the same safety and efficacy as the original NovoSeven(R)-but it can be transported and administered quickly.” NovoSeven RT has been manufactured to be room temperature stable (from 36 degrees F to 77 degrees F outside a refrigerator).

Which is the function of Factor XI plasma thromboplastin antecedent )?
FXI plays an important role in the clotting cascade, which leads to a clot. It helps generate more thrombin, a protein that converts fibrinogen to fibrin, which traps platelets and helps hold a clot in place.
What is the role of thromboplastin in blood clotting?
Thromboplastin (TPL) or thrombokinase is a mixture of both phospholipids and tissue factor found in plasma aiding blood coagulation through catalyzing the conversion of prothrombin to thrombin.
How is factor VII deficiency treated?
Specific treatment options for acute bleeds in individuals with factor VII deficiency include recombinant factor VII, prothrombin complex concentrates, and fresh frozen plasma. Antifibrinolytics such as aminocaproic acid can help alleviate the bleeding symptoms.
When to use recombinant factor VIIa off label?
Recombinant factor VIIa was initially developed for the treatment of hemorrhagic episodes in hemophilic patients with inhibitors to factors VIII and IX. After its introduction, it has also been used “off-label” to enhance hemostasis in nonhemophilic patients who experience bleeding episodes not responsive to conventional therapy.
Are there any side effects to factor VIIa?
Allergic side effects may rarely happen. Have blood work checked as you have been told by the doctor. Talk with the doctor. If you are 65 or older, use factor VIIa (recombinant) with care. You could have more side effects. Use with care in newborns. Talk with the doctor.
Which is a recombinant human coagulation factor VIIa?
NovoSeven®is recombinant human coagulation Factor VIIa (rFVIIa), intended for promoting hemostasis by activating the extrinsic pathway of the coagulation cascade.1NovoSeven is a vitamin K-dependent glycoprotein consisting of 406 amino acid residues (MW 50 K Dalton). NovoSeven is structurally similar to human plasma-derived Factor VIIa.
Is it safe to use factor VIIa in hemophilic patients?
Evidence so far indicates that the use of factor VIIa in hemophilic patients with inhibitors is both safe and effective. Anecdotal reports also suggest that the product is safe and effective in controlling bleeding in nonhemophilic patients.
