Protein C
Protein C Uses, Dosage, Side Effects, Food Interaction and all others data.
Protein C is an endogenously occurring plasma protein that plays a key role within the coagulation cascade. Protein C is a zymogen, or enzyme precursor, of a vitamin K-dependent anticoagulant glycoprotein (serine protease) that is synthesized in the liver. It is converted by the thrombin/thrombomodulin-complex on the endothelial cell surface to Activated Protein C (APC). Once in its activated form, APC functions as a serine protease with potent anticoagulant effects, especially in the presence of its cofactor protein S. APC exerts its effect by inactivating essential components of the coagulation cascade (specifically factors V and VIII), which leads to a decrease in thrombin formation, and therefore a reduction in clot formation.
The Protein C pathway provides a natural mechanism for control of the coagulation system and prevention of excessive procoagulant responses to activating stimuli. A lack of protein C in the body would lead to unchecked coagulation activation, resulting in thrombin generation and intravascular clot formation.
Protein C is available in concentrated form as the product Ceprotin, which is indicated for use in pediatric and adult patients with severe congenital protein C deficiency for the prevention and treatment of venous thrombosis and purpura fulminans.

Uses
Protein C is a medication used to treat protein C deficiency leading to purpura fulminans or coumarin-induced skin necrosis.
Protein C concentrate is indicated for pediatric and adult patients with severe congenital protein C deficiency for the prevention and treatment of venous thrombosis and purpura fulminans. It is also found as a component of some prothrombin complex concentrate (i.e. Factor IX Complex (Human)) formulations, such as Kcentra.
Protein C is also used to associated treatment for these conditions: Purpura Fulminans, Thrombosis, Venous
How Protein C works
Protein C is an endogenously occurring plasma protein that plays a key role within the coagulation cascade. Also known as blood coagulation factor XIV, Protein C is a zymogen, or enzyme precursor, of a vitamin K-dependent anticoagulant glycoprotein (serine protease) that is synthesized in the liver. It is converted by the thrombin/thrombomodulin-complex on the endothelial cell surface to Activated Protein C (APC). Once in its activated form, APC functions as a serine protease with potent anticoagulant effects, especially in the presence of its cofactor protein S. APC exerts its effect by inactivating essential components of the coagulation cascade (specifically factors V and VIII), which leads to a decrease in thrombin formation, and therefore a reduction in clot formation.
Food Interaction
- Avoid herbs and supplements with anticoagulant/antiplatelet activity. Examples include garlic, ginger, bilberry, danshen, piracetam, and ginkgo biloba.
