Apixaban
Keeb kwm
Apixaban yog ib qho kev xaiv zoo heev thiab thim rov qab inhibitor ntawm Factor Xa nrog Ki qhov txiaj ntsig ntawm 0.08 nM thiab 0.17 nM hauv tib neeg thiab luav, raws li [1].
Factor X, tseem paub los ntawm eponym Stuart-Prower yam, yog ib qho enzyme ntawm coagulation cascade.Factor X yog qhib, los ntawm hydrolysis, mus rau hauv factor Xa los ntawm ob qho tib si IX.Factor Xa yog daim ntawv qhib rau ntawm coagulation factorthrombokinase.Inhibiting Factor Xa tuaj yeem muab lwm txoj hauv kev los tiv thaiv kev coagulation.Direct Xa inhibitors yog nrov anticoagulants [2].
Nyob rau hauv vitro: Apixabanhas tau nthuav tawm cov qib siab ntawm potency, selectivity, thiab kev ua tau zoo ntawm Factor Xa nrog Ki ntawm 0.08 nM thiab 0.17 nM rau Human Factor Xa thiab Rabbit Factor Xa, feem [1].Apixaban ncua lub sijhawm ua ntshav ntawm tib neeg cov ntshav nrog cov concentrations (EC2x) ntawm 3.6, 0.37, 7.4 thiab 0.4 μM, uas yuav tsum tau ua raws li ob npaug ntawm lub sijhawm prothrombin (PT), hloov kho lub sijhawm prothrombin (mPT), qhib lub sijhawm thromboplastin ib nrab ( APTT) thiab HepTest.Tsis tas li ntawd, Apixaban tau pom qhov muaj zog tshaj plaws hauv tib neeg thiab luav plasma, tab sis tsawg dua potency hauv nas thiab dev ntshav hauv ob qho tib si PT thiab APTT kev soj ntsuam [3].
Hauv vivo: Apixaban tau nthuav tawm cov tshuaj pharmacokinetics zoo heev nrog kev tshem tawm tsawg heev (Cl: 0.02 L kg-1h-1), thiab qis ntim ntawm kev faib tawm (Vdss: 0.2 L / kg) hauv tus dev.Tsis tas li ntawd, Apixaban kuj tau pom qhov nruab nrab ib nrab-lub neej nrog T1 / 2 ntawm 5.8 teev thiab qhov ncauj zoo bioavailability (F: 58%) [1].Hauv arteriovenous-shunt thrombosis (AVST), venous thrombosis (VT) thiab hluav taws xob kho mob carotid arterial thrombosis (ECAT) luav qauv, Apixaban tsim cov tshuaj tiv thaiv thrombotic nrog EC50 ntawm 270 nM, 110 nM thiab 70 nM nyob rau hauv ib koob tshuaj-dependent yam. ].Apixaban cuam tshuam qhov cuam tshuam Xa kev ua haujlwm nrog IC50 ntawm 0.22 μM hauv luav ex vivo[4].Hauv chimpanzee, Apixaban kuj tau pom qhov ntim me me ntawm kev faib tawm (Vdss: 0.17 L kg-1), kev tshem tawm qis (Cl: 0.018 L kg-1h-1), thiab qhov ncauj zoo bioavailability (F: 59%) [5].
