The role of fibrinogen in the hemostatic process is crucial, but it is only one facet of a complex process. The hemostatic cascade involves the coordinated interaction of endothelial cells, platelets, and plasma proteins, leading to well-ordered activation and deactivation between coagulation factors. This process can be summarized in four key phases: initiation, amplification, propagation, and stabilization.

Important Safety Information

RiaSTAP®, Fibrinogen Concentrate (Human), is indicated for the treatment of acute bleeding episodes in patients with congenital fibrinogen deficiency, including afibrinogenemia and hypofibrinogenemia.

RiaSTAP is contraindicated in patients with known anaphylactic or severe systemic reactions to human plasma-derived products.

Monitor patients for early signs of anaphylaxis or hypersensitivity reactions and if necessary, discontinue administration and institute appropriate treatment. Thrombotic events have been reported in patients receiving RiaSTAP; weigh the benefits of administration versus the risks of thrombosis.

RiaSTAP is made from pooled human plasma. Products made from human plasma may contain infectious agents, eg, viruses and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent.

The most serious adverse reactions observed are thrombotic episodes (pulmonary embolism, myocardial infarction, deep vein thrombosis) and anaphylactic reactions. The most common adverse reactions observed in clinical studies (frequency >1%) were fever and headache.
