| Biochem/physiol Actions: | Fondaparinux sodium is an antithrombotic anticoagulant, a Factor Xa inhibitor. |
| Biochem/physiol Actions: | Fondaparinux sodium is an antithrombotic anticoagulant, a Factor Xa inhibitor. Fondaparinux sodium is chemically related to low molecular weight heparins. Its pentasaccharide structure corresponds to the antithrombin III (ATIII) binding site of heparin. Fondaparinux sodium binding at this site potentiates the natural inhibitory effect of ATIII against factor Xa by a factor of approximately 300, which results in inhibition of thrombin generation. |
| General description: | Fondaparinux sodium is a synthetic pentasaccharide that selectively inhibits Factor Xa via antithrombin III activation. It is used as an anticoagulant in the prevention and treatment of venous thromboembolism. The USP identification standard enables structural verification and analytical confirmation using NMR and chromatographic techniques. The USP biologics carbohydrates category includes a variety of carbohydrate-based substances that are essential in the development and manufacturing of therapeutic products. These carbohydrates play crucial roles in biological processes and are often utilized as excipients, stabilizers, or active ingredients in pharmaceuticals. The USP provides comprehensive standards, reference materials, and analytical procedures to ensure the identity, quality, purity, and consistency of carbohydrate therapeutics throughout their lifecycle. The United States Pharmacopeia (USP) provides quality standards for biologics to ensure their safety, efficacy, and quality throughout the manufacturing process. These standards assist manufacturers in adhering to regulatory requirements and help safeguard public health by reducing risks associated with biologics. |
