Pharmacology Research Paper Although currently available anticoagulants ar telling for the prevention and treatment of thromboembolic disorders, they assume several drawbacks. Low-molecular-weight heparins and fondaparinux competency relieve oneself a predictable level of anti curdling and requires no coagulation supervise; however, they must be given parenterally, which leave them to be awkward for long-term use. Vitamin K antagonists, warfarin, is administered vocally, but produce a versatile anticoagulant response because of intake vitamin K and ninefold do drugs interactions affect their metabolism (Augoustides, (2011). Consequently, coagulation monitoring and rat process adjustments are needed to ensure a alterative level of anticoagulation is reached. This is troublesome for patients and health care professionals, and costly for the health care system. These limitations have encouraged the development of tender oral anticoagulants that hindquarters thrombin or f actor Xa and can be given in frosty doses without coagulation monitoring. This paper focuses on a new oral anticoagulant rivaroxaban or xarelto.

Mechanism of Action Rivaroxaban or xarelto prevents Factor Xa (FXa) at a central point in the coagulation cascade, where the external and intrinsic pathways meet, helping to modulate thrombin generation. Preventing thrombin generation helps to inhibit clog up formation. Xarelto does not require a cofactor, such as antithrombin 3 for activity. Based on the studies, rivaroxaban exhibit selective inhibition of some(prenominal) free and cl! ot-bound FXa as well as FXa in the factor X complex (XARELTO®, 2012). Pharmacokinetics Rivaroxaban, an oral take in Factor Xa inhibitor, is an active complicated that exhibits high oral bioavailability, most 80%, and a fast onset and offset of action. blood plasma levels of rivaroxaban peak 23...If you hope to get a beneficial essay, order it on our website: OrderEssay.net
