Study Notes
- Low Molecular Weight Heparin (LMWH) is obtained by depolymerization of UFH and has greater activity against factor Xa.
- LMWHs have a more predictable anticoagulant response and do not require routine monitoring in most patients.
- LMWHs have a longer plasma half-life, allowing once or twice-daily administration.
- LMWHs have a lower risk of bleeding, HIT, and heparin-induced osteoporosis compared to UFH.
- Fondaparinux is an indirect inhibitor of factor Xa and has a predictable and linear dose-response relationship.
- Fondaparinux does not require routine coagulation monitoring or dose adjustments and has a long half-life.
- Warfarin has a narrow therapeutic index and requires frequent dose adjustments and patient monitoring.
- Warfarin inhibits the production of vitamin K-dependent coagulation factors and anticoagulant proteins.
- Warfarin dose requirements are influenced by various factors, including genetic variations, diet, and drug interactions.
- The dose of warfarin must be determined by frequent clinical and laboratory monitoring, and the initial dose must be overlapped with UFH or LMWHs.
