静脉血栓治疗后吃利伐沙班多久

(Rivaroxaban) is a new type of oral anticoagulant that has many obvious advantages over other traditional drugs. Specifically, it can highly selectively and directly inhibit bound or free factor Xa, thereby interrupting the endogenous and extrinsic coagulation pathways, inhibiting thrombin production, and ultimately inhibiting thrombosis.

Because rivaroxaban (Xarelto) cannot directly act on already produced thrombin, physiological hemostasis is less affected by it. The peak plasma concentration can be reached 2 to 4 hours after patients take this drug orally. It has the characteristics of strong anticoagulation such as rapid onset of action and rapid metabolism, and does not require monitoring of coagulation function. in the country, this drug was first approved for the prevention and treatment of venous thromboembolic disease. As people's understanding of it deepens, this drug is more and more widely used in clinical treatment.

So, how long does it take for rivaroxaban to take effect after venous thrombosis treatment?

Since the progression of each patient's disease is different, coupled with the interference and impact of nursing and other factors, it has not yet been determined how long patients need to take rivaroxaban. In general, the length of treatment a patient receives depends on each patient's risk of a venous thromboembolic event, which in turn depends on the type of orthopedic surgery the patient has undergone.

For patients who undergo major hip surgery, the clinically recommended treatment course is 5 weeks of treatment, which means that such patients generally need to take rivaroxaban for 5 weeks for one course of treatment; while for patients who undergo major knee surgery, the clinically recommended treatment course is 2 weeks of treatment, which means that such patients generally need to take rivaroxaban for 2 weeks for one course of treatment. If the patient misses taking the medicine during this period, he should take it as soon as possible, and then continue the previously recommended usage the next day, that is, take the medicine once a day.
