Factor X

Factor X Uses, Dosage, Side Effects, Food Interaction and all others data.

Coagulation Factor X (Human), is a plasma-derived human blood coagulation factor is used by adults and children (aged 12 years and above) with hereditary Factor X deficiency. However its use is limited in the perioperative setting for the management of bleeding in major surgery in patients with moderate and severe hereditary Factor X deficiency.

Coagulation Factor X is a vitamin K-dependent, liver-produced serine protease that serves as the first enzyme in the coagulation cascade to form fibrin. It is a two-chain glycoprotein with the molecular weight of approximately 59 kDa . While Factor X normally circulates in the plasma as inactive molecules, the activation of Factor X is involved in both the intrinsic and extrinsic coagulation pathways. Inherited factor X deficiency is a rare autosomal recessive bleeding disorder that is estimated to occur in 1:1 000 000 individuals up to 1:500 carriers . Administration of coagulation Factor X from healthy donor serves to restore and achieve effective hemostasis.

Coagulation Factor X (Human) solution is approved by the FDA for intravenous injection under the market name Coagadex which contains normally 100 IU/mL of coagulation Factor X derived from healthy donors who have passed viral screening tests .

Uses

Factor X is a coagulation factor used to treat Factor X deficiency to control bleeding.

Indicated in adults and children (aged 12 years and above) with hereditary Factor X deficiency for on-demand treatment and control of bleeding episodes, or for perioperative management of bleeding in patients with mild hereditary Factor X deficiency .

Factor X is also used to associated treatment for these conditions: Bleeding caused by Factor X Deficiency, Perioperative bleeding caused by Factor X Deficiency, Vitamin K antagonist induced major bleeding

How Factor X works

Factor X is an inactive zymogen that is synthesized in the liver, which can be activated by Factor IXa (via the intrinsic pathway) or by Factor VIIa (via the extrinsic pathway). It is composed of a light chain which contains the Gla (glutamic acid) domain and two epidermal growth factor domains, and a heavy chain that contains the catalytic serine protease domain . The conversion of inactive Factor X into the active form Factor Xa requires the cleavage of a 52-residue peptide from the heavy chain and the release of 52-residue activation peptide that contains the His236, Asp228 and Ser379 catalytic site. This activation step can occur through the extrinsic or intrinsic pathway and is considered to be the first step in the common pathway to fibrin formation .

Factor Xa plays a critical initiation step of the coagulation pathway by cleaving and activating prothrombin to thrombin in complex with FVa, Ca2+ and phospholipids. This complex is also known as the prothrombinase complex. Thrombin then acts upon soluble fibrinogen and Factor XIII to generate a cross-linked fibrin clot .
