Pharmacological action of

The mechanism of action of apixaban is the inhibition of FXa activity. As a result of this, apixaban changes the values ​​of the indicators of the blood coagulation system:

lengthens the prothrombin time, MHO and activated partial thromboplastin time (APTT). Changes in these parameters when using the drug in a therapeutic dose are insignificant and individual. Therefore, their use in order to assess the pharmacodynamic activity of apixaban is not recommended.

Inhibition of FXa activity by apixaban was proved using a chromogenic test using Rotachrom heparin. \ Change in anti-FXa activity is directly proportional to an increase in the concentration of apixaban in plasma, blood, while the maximum activity values ​​are observed when the maximum concentration of apixaban in the blood plasma is reached.

A linear relationship between the concentration and anti-FXa activity of apixaban is recorded in a wide range of therapeutic doses of the drug! Changes in anti-FXa activity with changes in dose and concentration, apixaban are more pronounced and less variable than blood coagulation. The expected maximum and minimum anti-FXa activity of apixaban in equilibrium, when applied at a dose of 2.5 mg-2 times a day, is 1.3 IU / ml (5/95 percentile - 0.67 IU / ml - 2 , 4 IU / ml) and 0.84 IU / ml (5/95 percentile -0.37 IU / ml - 1.8 IU / ml), respectively, which correlates with the fluctuations of this indicator in the interval between doses of the drug (less than 1.6 times). Against the background of apixaban therapy, routine monitoring of its concentration in blood plasma is not required, however, performing the Rotachrom anti-FXa activity test may be useful for deciding whether to continue therapy.

Mechanism of Action

Apixaban is a potent direct FXa inhibitor that reversibly and selectively blocks the active site of an enzyme for oral use. To implement the antithrombotic effect of apixaban, the presence of antithrombin III is not required. Apixaban inhibits free and bound FXa, as well as prothrombinase activity. Apixaban does not have a direct direct effect on platelet aggregation, but indirectly inhibits platelet aggregation induced by thrombin. By inhibiting the activity of FXa, apixaban prevents the formation of thrombin and blood clots.

Drug Interaction

Effect of Other Drugs on the Pharmacokinetics of Apixaban Isoenzyme Inhibitors CYP3A4 and P-Glycoprotein

Combination of apixaban with ketoconazole (400 mg, once daily), which is potent and CYP raising the mean AUC of apixaban 2-fold and the mean Cmax - 1.6-fold. No dose adjustment of apixaban when combined with ketoconazole is required, however, apixaban should be used with caution in patients receiving systemic therapy with azole antifungal agents, in particular ketoconazole, or other potent CYP3A4 isoenzyme inhibitors and P-glycoproteins.

Drugs that moderately reduce the rate of apixaban excretion or inhibit the CYP3A4 isoenzyme and / or P-glycoprotein are expected to result in a lower plasma apixaban concentration. For example, diltiazem (a moderate CYP3A4 isoenzyme inhibitor and a weak P-glycoprotein inhibitor) at a dose of 360 mg once daily resulted in a 1.4-fold increase in the mean AUC of apixaban and a 1.3-fold mean Cmax. Naproxen (a P-glycoprotein inhibitor), when administered at a dose of 500 mg in healthy volunteers, increased the mean AUC and Cmax of apixaban 1.5 and 1.6 times, respectively. At the same time, there was an increase in the values ​​of the coagulation system. However, no effect of naproxen on platelet aggregation was observed against such a combination, associated with impaired arachidonic acid metabolism, and clinically significant prolongation of bleeding time.

No dose adjustment of apixaban when combined with moderate CYP3A4 isoenzyme inhibitors and / or P-glycoprotein is required.

CYP3A4 and P-glycoprotein isoenzyme inducers

Combination of apixaban with rifampicin (a potent inducer of CYP3A4 and P-glycoprotein isoenzyme) resulted in a decrease in the mean AUC and Cmax of apixaban by approximately 54% and 42%, respectively. The combination of apixaban with other potent inducers of the CYP3A4 isoenzyme and P-glycoprotein (in particular, phenytoin, carbamazepine, phenobarbital, or perforated periwort drugs) may also appear to reduce the concentration of apixababan in plasma. The dose adjustment of apixaban when combined with the agents of this group is not required, however, they should be combined with caution.

Anticoagulants, platelet aggregation inhibitors and NSAIDs

Following the co-administration of enoxaparin (40 mg once) and apixaban (5 mg once), the additive effect of these agents on FXa activity was observed.

There were no signs of pharmacokinetic or pharmacodynamic interaction of apixaban with acetylsalicylic acid (325 mg, once daily).

Combining apixaban with clopidogrel (75 mg, once daily) or a combination of clopidogrel (75 mg) and acetylsalicylic acid (162 mg, once daily) in phase I of the clinical study did not lead to an increase in bleeding time, further inhibition of platelet aggregation or increase in blood coagulation (prothrombin time, MHO, and APTV) compared with the use of these antiplatelet agents in monotherapy.

However, caution should be exercised when co-administering apixaban with NSAIDs (including acetylsalicylic acid), since these drugs increase the risk of bleeding.

It is not recommended to use concurrently drugs that may be associated with the development of serious bleeding, such as unfractionated heparin or heparin derivatives (including low molecular weight heparins), oligosaccharides, FXa inhibitors (eg fondaparinux), direct II inhibitors, eg , thrombolytic drugs, IIb / IIIa glycoprotein receptor antagonists, thienopyridines (eg, clopidogrel), dipyridamole, dextran, sulfinpyrazone, vitamin K antagonists, and other anticoagulants for oral administration. It should be noted that unfractionated heparin can be used at the doses required to support the patency of a venous or arterial catheter.

Combination with other drugs

No clinically relevant pharmacokinetic or pharmacodynamic interaction of apixaban with atenolol or famotidine has been identified. The combination of apixaban (10 mg dose) with atenolol (100 mg dose) did not lead to the development of clinically relevant changes in the pharmacokinetics of apixaban, but was accompanied by a 15% and 18% decrease in the mean AUC and Cmax of apixaban, respectively, compared with the regimen. monotherapy. The administration of apixaban (10 mg dose) with famotidine (40 mg dose) did not affect the AUC or Cmax of apixaban.

Effect of apixaban on the pharmacokinetics of other drugs

In vitro studies, apixaban did not inhibit the activity of CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2D6 or CYP3A4 / isoenzymes. activity of CYP2C19 isoenzyme (IC50> 20 μmol / l) by apixaban at a concentration significantly exceeding the maximum concentration of the drug in blood plasma when used clinically. Apixaban is not an inducer of CYP1A2, CYP2B6, CYP3A4 / 5 isoenzymes at concentrations up to 20 μmol / L. In this regard, it is expected that when used together, it will not affect the clearance of drugs, metabolized by these isoenzymes. In addition, apixaban does not significantly inhibit P-glycoprotein activity.

In studies in healthy volunteers, apixaban did not significantly alter the pharmacokinetics of digoxin, naproxen, or atenolol.

Overdose

Symptoms: Increased risk of bleeding. In controlled clinical trials, apixaban was taken orally by healthy volunteers at doses up to 50 mg / day for 3–7 days (25 mg, 2 times daily for 7 days or 50 mg, 1 time for 3 days) for clinically relevant patients. there were no undesirable effects.

Treatment: Activated carbon can be considered. The antidote of the drug is unknown.
