Decreased heparin sensitivity of cyclohexanedione-modified factor Xa
Thrombosis and Haemostasis
|August 31, 1979
Abstract:
Modification of 12 arginine residues of bovine Factor Xa with 1,2-cyclohexanedione has resulted in a decrease in heparin sensitivity of the reaction between enzyme and antithrombin-III, whereas the antithrombin-III sensitivity of modified Factor Xa was only slightly affected. It is suggested that heparin accelerates the Factor Xa-antithrombin-III reaction by interacting with Factor Xa.

Anticoagulant Drugs: Low-Molecular-Weight Heparins
Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...
Nonlinear Pharmacokinetics: Dependence of Elimination Half-Life and Dose Clearance
The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.

Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
