Imvelaphi

I-Apixaban yi-inhibitor ekhethiweyo kunye ne-reversible inhibitor ye-Factor Xa enexabiso le-Ki ye-0.08 nM kunye ne-0.17 nM kumntu kunye nomvundla, ngokulandelanayo[1].

I-Factor X, ekwabizwa ngegama elithi Stuart-Prower factor, yi-enzyme ye-coagulation cascade.I-Factor X iyasebenza, nge-hydrolysis, ibe yi-factor Xa zombini i-IX.I-Factor Xa yindlela esetyenzisiweyo ye-coagulation factorthrombokinase.I-Inhibiting Factor Xa inokunika enye indlela ye-anticoagulation.Direct Xa inhibitors zithandwa anticoagulants [2].

I-In vitro: I-Apixabanhas ibonise izinga eliphezulu lamandla, ukukhetha, kunye nokusebenza kakuhle kwi-Factor Xa kunye ne-Ki ye-0.08 nM kunye ne-0.17 nM ye-Human Factor Xa kunye ne-Rabbit Factor Xa, ngokulandelanayo [1].I-Apixaban yandisa amaxesha okuvala i-plasma yomntu eqhelekileyo kunye nokugxininiswa (EC2x) ye-3.6, 0.37, 7.4 kunye ne-0.4 μM, efunekayo ngokulandelanayo ukuphindaphinda ixesha le-prothrombin (PT), ixesha leprothrombin elilungisiweyo (mPT), ixesha elisebenzayo le-thromboplastin ( APTT) kunye neHepTest.Ngaphandle koko, i-Apixaban ibonise amandla aphezulu kwi-plasma yomntu kunye nomvundla, kodwa amandla amancinci kwi-rat kunye ne-dog plasma kuzo zombini ii-PT kunye ne-APTT assays [3].

Kwi-vivo: I-Apixaban ibonise i-pharmacokinetics egqwesileyo enemvume ephantsi kakhulu (Cl: 0.02 L kg-1h-1), kunye nomthamo ophantsi wokusabalalisa (Vdss: 0.2 L / kg) kwinja.Ngaphandle koko, i-Apixaban iphinde yabonisa i-half-life half-life kunye ne-T1 / 2 yeeyure ze-5.8 kunye ne-bioavailability yomlomo omhle (F: 58%) [1].Kwi-arteriovenous-shunt thrombosis (AVST), i-venous thrombosis (VT) kunye ne-carotid arterial thrombosis (ECAT) imodeli yomvundla, i-Apixaban ivelise iziphumo ze-antithrombotic kunye ne-EC50 ye-270 nM, i-110 nM kunye ne-70 nM ngendlela exhomekeke kwi-dose [3]. ].I-Apixaban inhibited kakhulu xa umsebenzi nge-IC50 ye-0.22 μM kumvundla ex vivo[4].Kwi-chimpanzee, i-Apixaban nayo yabonisa umthamo omncinci wokusabalalisa (Vdss: 0.17 L kg-1), imvume ephantsi yenkqubo (Cl: 0.018 L kg-1h-1), kunye ne-bioavailability yomlomo omhle (F: 59%) [5].
