Absorption
Apixaban is approximately 50% bioavailable though other studies report 43-46% oral bioavailability.
Route of Elimination
56% of an orally administered dose is recovered in the feces and 24.5-28.8% of the dose is recovered in the urine. 83-88% of the dose recovered in the urine was the unchanged parent compound.
Volume of Distribution
Approximately 21L.
Clearance
3.3L/h though other studies report 4876mL/h.
Distribution in pregnant rats/fetuses: Cmax in amnion was high. Significant concentrations were found in placenta and fetal blood, kidney and liver. Toxicokinetic data collected in the reproductive and developmental toxicity studies in rats, mice and rabbits showed that generally fetal plasma concentrations of apixaban were lower than those in the dams.

Two single dose radiolabel distribution studies were provided in rats. The data show a wide distribution, with the highest values in excretory organs (liver, kidney, urinary bladder (and contents), bile) and intestinal tract (and contents). After a dose of 20 mg/kg in male Long-Evans rats also relatively high Cmax and AUC were found in adrenals, lungs, thyroid gland, but after a dose of 5 mg/kg in Sprague Dawley rats (both sexes) these organs showed Cmax similar to most other organs and tissues. There was no qualitative difference in distribution between male and female rats, but the female rats showed higher Cmax values in the intestinal tract.

Protein binding differs between the species. The unbound fraction at concentrations of 1-10 uM is about 13% in human vs about 4% in rats and 8% in dogs. At the tested concentrations there was no effect of concentration or gender. In mice protein binding is much lower, with 44-6 % unbound, dependent on the tested concentration (range 100-2000 ng apixaban/mL).

50% of the orally administered dose is excreted as the unchanged parent compound, however 25% of the dose is excreted as O-demethyl apixaban sulfate. All apixaban metabolites account for approximately 32% of the excreted dose though the structure of all metabolites are not well defined. Apixaban is mainly metabolized by cytochrome p450(CYP)3A4 and to a lesser extent by CYP1A2, CYP2C8, CYP2C9, CYP2C19, and CYP2J2.
Approximately 25% of an orally administered apixaban dose is recovered in urine and feces as metabolites. Apixaban is metabolized mainly via CYP3A4 with minor contributions from CYP1A2, 2C8, 2C9, 2C19, and 2J2. O-demethylation and hydroxylation at the 3-oxopiperidinyl moiety are the major sites of biotransformation. Unchanged apixaban is the major drug-related component in human plasma; there are no active circulating metabolites.

Apixaban is mainly metabolized by CYP3A4/5 with conjugation via SULT1A1, but several other CYP and SULT isozymes are also involved. No apixaban metabolites were found to have pharmacological activity and there were no unique human metabolites.
European Medicines Agency (EMA), Committee for Medicinal Products for Human Use (CHMP), European Public Assessment Report (EPAR): Eliquis (Apixaban) p.13 (2011). Available from, as of March 26, 2015: https://www.ema.europa.eu/docs/en_GB/document_library/EPAR_-_Public_assessment_report/human/002148/WC500107726.pdf
The metabolism and disposition of (14)C-apixaban, an orally bioavailable, highly selective, and direct acting/reversible factor Xa inhibitor, was investigated in 10 healthy male subjects without (group 1, n=6) and with bile collection (group 2, n=4) after a single 20-mg oral dose. Urine, blood, and feces samples were collected from all subjects. Bile samples were also collected for 3 to 8 hr after dosing from group 2 subjects. There were no serious adverse events or discontinuations due to adverse effects. In plasma, apixaban was the major circulating component and O-demethyl apixaban sulfate, a stable and water-soluble metabolite, was the significant metabolite. The exposure of apixaban (C(max) and area under the plasma concentration versus time curve) in subjects with bile collection was generally similar to that in subjects without bile collection. The administered dose was recovered in feces (group 1, 56.0%; group 2, 46.7%) and urine (group 1, 24.5%; group 2, 28.8%), with the parent drug representing approximately half of the recovered dose. Biliary excretion represented a minor elimination pathway (2.44% of the administered dose) from group 2 subjects within the limited collection period. Metabolic pathways identified for apixaban included O-demethylation, hydroxylation, and sulfation of hydroxylated O-demethyl apixaban. Thus, apixaban is an orally bioavailable inhibitor of factor Xa with elimination pathways that include metabolism and renal excretion.

The metabolism and disposition of (14)C-apixaban, a potent, reversible, and direct inhibitor of coagulation factor Xa, were investigated in mice, rats, rabbits, dogs, and humans after a single oral administration and in incubations with hepatocytes. In plasma, the parent compound was the major circulating component in mice, rats, dogs, and humans. O-Demethyl apixaban sulfate (M1) represented approximately 25% of the parent area under the time curve in human plasma. This sulfate metabolite was present, but in lower amounts relative to the parent, in plasma from mice, rats, and dogs. Rabbits showed a plasma metabolite profile distinct from that of other species with apixaban as a minor component and M2 (O-demethyl apixaban) and M14 (O-demethyl apixaban glucuronide) as prominent components. The fecal route was a major elimination pathway, accounting for >54% of the dose in animals and >46% in humans. The urinary route accounted for <15% of the dose in animals and 25 to 28% in humans. Apixaban was the major component in feces of every species and in urine of all species except rabbit. M1 and M2 were common prominent metabolites in urine and feces of all species as well as in bile of rats and humans. In vivo metabolite profiles showed quantitative differences between species and from in vitro metabolite profiles, but all human metabolites were found in animal species. After intravenous administration of (14)C-apixaban to bile duct-cannulated rats, the significant portion (approximately 22%) of the dose was recovered as parent drug in the feces, suggesting direct excretion of the drug from gastrointestinal tracts of rats. Overall, apixaban was effectively eliminated via multiple elimination pathways in animals and humans, including oxidative metabolism, and direct renal and intestinal excretion.
PMID:19420130 Zhang D et al; Drug Metab Dispos 37 (8): 1738-48 (2009)
... The O-demethyl apixaban sulfate is a major circulating metabolite in humans but circulates at lower concentrations relative to parent in animals. The aim of this study was to identify the sulfotransferases (SULTs) responsible for the sulfation reaction. Apixaban undergoes O-demethylation catalyzed by cytochrome P450 enzymes to O-demethyl apixaban, and then is conjugated by SULTs to form O-demethyl apixaban sulfate. Of the five human cDNA-expressed SULTs tested, SULT1A1 and SULT1A2 exhibited significant levels of catalytic activity for formation of O-demethyl apixaban sulfate, and SULT1A3, SULT1E1, and SULT2A1 showed much lower catalytic activities. In human liver S9, quercetin, a highly selective inhibitor of SULT1A1 and SULT1E1, inhibited O-demethyl apixaban sulfate formation by 99%; 2,6-dichloro-4-nitrophenol, another inhibitor of SULT1A1, also inhibited this reaction by >90%; estrone, a competitive inhibitor for SULT1E1, had no effect on this reaction. The comparable K(m) values for formation of O-demethyl apixaban sulfate were 41.4 microM (human liver S9), 36.8 microM (SULT1A1), and 70.8 microM (SULT1A2). Because of the high level of expression of SULT1A1 in liver and its higher level of catalytic activity for formation of O-demethyl apixaban sulfate, SULT1A1 might play a major role in humans for formation of O-demethyl apixaban sulfate. O-Demethyl apixaban was also investigated in liver S9 of mice, rats, rabbits, dogs, monkeys, and humans. The results indicated that liver S9 samples from dogs, monkeys, and humans had higher activities for formation of O-demethyl apixaban sulfate than those of mice, rats, and rabbits.
