Pharmacological action

Elikvis - direct-acting anticoagulant - a selective inhibitor of factor Xa blood coagulation.

The mechanism of action of apixaban is to inhibit the activity of FXa. 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 indicators 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.

Apixaban inhibition of FXa activity was confirmed by a chromogenic test using Rotachrom heparin. The change in anti-FXa activity is directly proportional to the increase in the concentration of apixaban in blood plasma, while the maximum values ​​of activity are observed when reaching Cmax of apixaban in blood plasma. 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 apixaban concentration 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 / day, is 1. 3MU / ml (5/95 percentile - 0.67 IU / ml - 2.4 IU / ml) and 0.84 IU / ml (5/95 percentile -0.37ME / 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, the Rotachrom anti-FXa activity test may be useful for deciding whether to continue therapy.

Precautions:

Risk of bleeding

As with other anticoagulants, careful monitoring of patients is necessary, taking ElikvisВ®, for the development of bleeding. The drug is recommended to be used with caution in conditions characterized by an increased risk of bleeding: congenital or acquired blood coagulation disorders, exacerbations of gastrointestinal ulcer conditions, bacterial endocarditis, thrombocytopenia, hemorrhagic stroke, a history of severe uncontrolled arterial hypertension, or recent surgical intervention or . If severe bleeding develops, ElikvisВ® should be discontinued.

With the development of hemorrhagic complications, the drug must be discontinued and screened to determine the source of bleeding. Consideration should also be given to the need for appropriate treatment, in particular surgical stopping of bleeding or transfusion of freshly frozen blood plasma.

Performing spinal, epidural anesthesia or punctures in patients receiving ElixisВ®

When performing spinal or epidural anesthesia or punctures of appropriate spaces in patients receiving antithrombotic agents to prevent thromboembolism, there is a risk of developing epidural or spinal hematomas, which in turn may cause persistent or irreversible paralysis. This risk may increase even more with the use of an installed epidural catheter in the postoperative period or with the parallel use of other drugs that affect hemostasis. Established epidural or subarachnoid catheters must be removed for at least 5 hours before the first dose of ElixisВ® is administered. A similar increase in risk can be observed when performing traumatic or multiple punctures of the epidural or subarachnoid spaces. Frequent monitoring of patients is necessary for the development of manifestations of impaired nervous system function (in particular, numbness or weakness of the lower extremities, impaired bowel or bladder function). With the development of such disorders, an emergency examination and treatment is necessary. Before performing interventions on epidural or subarachnoid spaces in patients receiving anticoagulants, including in order to prevent thrombosis, an assessment of the ratio of potential benefits and risks is necessary.

Surgery for hip fracture

In clinical trials, ElvisВ® was not used in patients who underwent surgery for a hip fracture, therefore its effectiveness and safety in this category of patients are unknown, and its use is not recommended.

Use during pregnancy and lactation

There is only limited information on the use of Elikvis® during pregnancy. The use of apixaban during pregnancy is not recommended.

There is no evidence of the excretion of apixaban or its metabolites in human breast milk. If it is necessary to use the drug Elikvis® during lactation, breastfeeding should be discontinued.

Special instructions

As with other anticoagulants, careful monitoring of patients taking Elikvis is necessary for the development of bleeding. With the development of severe bleeding, the drug Elikvis should be discontinued. With the development of hemorrhagic complications, it is necessary to cancel treatment with the drug and perform an examination to determine the source of bleeding. If necessary, appropriate treatment is prescribed, in particular surgical stopping of bleeding or transfusion of freshly frozen blood plasma.

Performing spinal, epidural anesthesia or puncture in patients receiving Eliquis

When performing spinal or epidural anesthesia or diagnostic puncture of these areas in patients receiving antithrombotic agents to prevent thromboembolism, there is a risk of developing epidural or spinal hematomas, which, in turn, may cause persistent or irreversible paralysis. This risk may increase even more with the use of an installed epidural catheter in the postoperative period or with the parallel use of other drugs that affect hemostasis. Installed epidural or subarachnoid catheters should be removed at least 5 hours before the first dose of Elikvis.

A similar increase in risk may occur with traumatic or multiple punctures of epidural or subarachnoid spaces. Frequent monitoring of patients is necessary for the development of manifestations of impaired nervous system function (in particular, numbness or weakness of the lower extremities, impaired bowel or bladder function). With the development of such disorders, an emergency examination and treatment is necessary. Before performing interventions on epidural or subarachnoid spaces in patients receiving anticoagulants, including in order to prevent thrombosis, an assessment of the ratio of potential benefits and risks is necessary.

Influence on the ability to drive vehicles and control mechanisms

Elikvis does not have a significant impact on the ability to drive a car and work with mechanisms.

In patients suffering from impaired liver function of mild or moderate severity, dose adjustment of the drug is not required. The use of the drug in patients with severe hepatic insufficiency is not recommended.

Side effects

Adverse reactions were observed in 11% of patients receiving apixaban in a dose of 2.5 mg 2 times / day. As with other anticoagulants, bleeding can occur in patients with risk factors, such as organic damage associated with bleeding. The most common side effects were anemia, bleeding, bruising, and nausea. Adverse reactions developed in patients undergoing orthopedic surgery, on the background of apixaban therapy are presented below.

Further, the frequency of adverse reactions is understood: often -> 1/100, <1/10, infrequently -> 1/1000, <1/100, rarely -> 1/10000, <1/1000.

Drug interactions

Effect of other drugs on the pharmacokinetics of apixaban

Inhibitors of CYP3A4 and P-glycoprotein

Combination of apixaban with ketoconazole (at a dose of 400 mg, 1 time per day), which is an increase in the rate of the potency of the 4 the average AUC of apixaban is 2 times and the average Cmax is 1.6 times. Dose adjustment of apixaban when combined with ketoconazole is not required, however, apixaban should be used with caution in patients receiving systemic therapy with azole antifungal agents, in particular ketoconazole, or other powerful inhibitors of CYP3A4 and P-glycoprotein.

drugs, moderately inhibiting the elimination of apixaban, CYP3A4 and / or P-glycoprotein is expected to lead to an increase in the concentration of apixaban in blood plasma to a lesser extent. For example, diltiazem (at a dose of 360 mg, 1 time per day), which is considered a moderate inhibitor of CYP3A4 and a weak inhibitor of P-glycoprotein, provided an increase in the average AUC of apixaban by 1.4 times and the average Cmax by 1.3 times.

Naproxen (at a dose of 500 mg), which is an inhibitor of P-glycoprotein, provided an increase in the average AUC and Cmax of apixaban by 1.5 and 1.6 times, respectively. At the same time, an increase in the values ​​of the indicators of the blood coagulation system was noted. However, against the background of such a combination, there was no change in the effect of naproxen on platelet aggregation induced by arachidonic acid, and a clinically significant extension of bleeding time.

Dose adjustment of apixaban when combined with less active inhibitors of CYP3A4 and / or P-glycoprotein is not required.

Inducers of CYP3A4 and P-glycoprotein

Combining apixaban with rifampicin (a potent inducer of CYP3A4 and P-glycoprotein) led to a decrease in average AUC and Cmax of apixaban by approximately 54 and 42%, respectively. Therefore, the combination of apixaban with other powerful inducers of CYP3A4 and P-glycoprotein (in particular phenytoin, carbamazepine, phenobarbital or perforated hypericum preparations) can also lead to a decrease in the concentration of apixaban in blood plasma. Nevertheless, dose adjustment of apixaban when it is combined with the agents of this group is not required, however, these agents should be combined with caution.

Anticoagulants

After co-administration of enoxaparin (once, at a dose of 40 mg) and apixaban (once, at a dose of 5 mg), the additive effect of these agents on the activity of factor Xa was noted.

In view of the increased risk of bleeding, it is necessary to combine apixaban with other anticoagulants with caution.

Inhibitors of platelet aggregation and NSAIDs

No evidence of pharmacokinetic or pharmacodynamic interaction of apixaban with acetylsalicylic acid (325 mg, 1 time per day).

The combination of apixaban with clopidogrel (at a dose of 75 mg, 1 time per day) or a combination of clopidogrel (75 mg) and acetylsalicylic acid (162 mg, 1 time per day) did not lead to an increase in bleeding time, platelet aggregation, or indicators of the blood coagulation system ( PV INR and APTT) compared with the use of these antiplatelet agents in monotherapy.

Despite these data, it is possible to enhance the pharmacodynamic response to antiplatelet therapy when used in combination with apixaban. Therefore, caution should be exercised when combining it with NSAIDs (including acetylsalicylic acid) and / or platelet aggregation inhibitors, since these drugs usually increase the risk of bleeding.

Combination with other drugs

No clinically significant pharmacokinetic or pharmacodynamic interaction of apixaban with atenolol or famotidine has been identified. The combination of apixaban (at a dose of 10 mg) with atenolol (at a dose of 100 mg) did not lead to the development of clinically significant changes in the pharmacokinetics of apixaban, however, it was accompanied by a decrease in the average values ​​of AUC and Cmax of apixaban by 15 and 18% than with its use in monotherapy. The combination of apixaban (at a dose of 10 mg) with famotidine (at a dose of 40 mg) did not affect the AUC or Cmax of apixaban.

Effect of apixaban on the pharmacokinetics of other drugs

In vitro studies have not revealed an inhibitory effect of apixaban on the activity of CYP1A2, CYP2A6, CYP2B6, CYP2C8, CYP2C9, CYP2D6 or CYP3A4 (IC50> has a weak inhibitory effect) and CYP2C19 (IC50> 20 μmol / L) in a concentration significantly higher than the Cmax of the drug in blood plasma during its clinical use.

Apixaban was not an inducer of CYP1A2, CYP2B6, CYP3A4 / 5 in concentrations up to 20 μmol / L. Therefore he is expected will not affect the metabolic clearance of drugs metabolized by these isoenzymes when used together. In addition, apixaban does not significantly inhibit the activity of P-glycoprotein.

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

digoxin. The combination of apixaban (at a dose of 20 mg, 1 time per day) and digoxin (at a dose of 0.25 mg, 1 time per day), which is a substrate of P-glycoprotein, did not affect the AUC or Cmax of digoxin. Therefore, apixaban does not inhibit the transport of P-glycoprotein substrates.

naproxen. The combination of apixaban (a single dose of 10 mg) and naproxen (500 mg), a commonly used NSAID, did not affect the AUC or Cmax of naproxen.

Atenolol. The combination of apixaban (a single dose of 10 mg) and atenolol (100 mg), a commonly used beta-blocker, did not affect the pharmacokinetics of the latter.

overdose

Symptoms: an overdose may increase the risk of bleeding. In controlled clinical trials, apixaban was administered orally to healthy volunteers at doses up to 50 mg / day for 3 to 7 days (25 mg twice daily for 7 days or 50 mg once daily for 3 days) 10 times above the maximum recommended dose for a person of clinically significant undesirable effects was not noted.

Treatment: Apixaban antidote is unknown. Preclinical studies have shown that that oral administration of activated charcoal within 3 h after oral administration of apixaban reduced the exposure values ​​of apixaban, so in the case of overdose of this drug, consideration may be given to the use of activated charcoal.
