Rivaroxabanyog ib qho tshiab ntawm qhov ncauj anticoagulant uas yog qhov ncaj qha Xa inhibitor.
1. Mechanism ntawm kev ua
Coagulation factor Xa ua lub luag haujlwm tseem ceeb hauv cov txheej txheem coagulation. Nws yog nyob rau ntawm kev sib tshuam ntawm endogenous thiab exogenous coagulation txoj kev thiab converts prothrombin rau thrombin. Rivaroxaban ua ncaj qha rau ntawm coagulation factor Xa, thiab los ntawm kev xaiv inhibiting nws cov haujlwm, nws thaiv kev tsim cov thrombin, yog li inhibiting ntshav coagulation.
2. Clinical application scenarios
Tom qab kev phais orthopedic (xws li lub duav lossis lub hauv caug hloov), cov neeg mob yuav muaj kev pheej hmoo siab ntawm venous thrombosis vim kev phais mob, lub txaj ntev ntev, thiab lwm yam. Rivaroxaban tuaj yeem txo qhov kev pheej hmoo ntawm VTE hauv cov neeg mob no, suav nrog kev tiv thaiv ntawm cov hlab ntsha sib sib zog nqus (DVT) thiab pulmonary embolism (PE) vim DVT detachment.
Rivaroxaban tuaj yeem siv los kho cov neeg mob uas tau kuaj pom tias muaj VTE thiab tuaj yeem yaj cov ntshav txhaws uas twb tau tsim thiab txo cov tsos mob xws li o thiab mob ntawm ob txhais ceg. Hauv cov neeg mob uas tsis yog -valvular atrial fibrillation, cov ntshav nyiam mus rau hauv lub atria thiab tsim cov ntshav txhaws raws li lub atria poob lawv cov kev sib dhos zoo li qub. Rivaroxaban tuaj yeem txo qhov kev pheej hmoo ntawm mob stroke hauv cov neeg mob no thiab tiv thaiv qhov tshwm sim loj xws li cerebral embolism los ntawm cov ntshav txhaws.
3. Qhov zoo thiab nta
Ib qho yooj yim siv: Rivaroxaban yog ib qho kev npaj ntawm qhov ncauj, uas yog qhov yooj yim rau siv piv rau cov tshuaj anticoagulants (xws li warfarin) uas yuav tsum tau saib xyuas cov coagulation tsis tu ncua thiab kev hloov ntau npaum li cas. Cov neeg mob tsis tas yuav mus rau hauv tsev kho mob rau kev kuaj ntshav ntau zaus los kho cov tshuaj, uas ua rau cov neeg mob ua raws li txoj cai.
Kev pib sai ntawm kev nqis tes ua thiab cov txiaj ntsig ruaj khov: Tom qab kev tswj hwm qhov ncauj, nws tuaj yeem nqus tau sai thiab ua kom muaj cov nyhuv anticoagulant. Tsis tas li ntawd, nws cov nyhuv anticoagulant yog qhov ruaj khov, thiab nws tuaj yeem tswj tau cov xwm txheej ntawm cov tshuaj tiv thaiv coagulant tau zoo raws li qhov tsim nyog, uas txo cov kev pheej hmoo ntawm kev tsis txaus los tiv thaiv coagulation lossis ntau dua -anticoagulation.
