Composition

Composition per syringe:

Active ingredient:

enoxaparin sodium 40 mg*;

Solvent: water for injection up to 0.4 ml;

* – weight calculated based on the content of enoxaparin sodium used (theoretical activity 100 anti-Xa IU / mg).

Pharmacological action

Enoxaparin sodium is a low molecular weight heparin with an average molecular weight of about 4500 daltons (Da): less than 2000 Da – < 20%, from 2000 to 8000 Da – > 68%, more than 8000 Da – < 20%, from 2000 to 8000 Da – > Enoxaparin sodium is obtained by alkaline depolymerization of benzyl ether of heparin isolated from the mucosa of the small intestine of pigs. Its structure is characterized by a non-reducing fragment of 2-O-sulfo-4-enpyrazinosuronic acid and a reducing fragment of 2-No,6-O-disulfo-O-glucopyranoside. The structure of enoxaparin sodium contains about 20% (ranging from 15% to 25%) of the 1,6-anhydro derivative in the reducing fragment of the polysaccharide chain.

Pharmacodynamics

In a purified in vitro system, enoxaparin sodium has high anti-Xa activity (approximately 100 IU / ml) and low anti-IIa or antithrombin activity (approximately 28 IU/ml). This anticoagulant activity acts through antithrombin III (AT-Sh), providing anticoagulant activity in humans. Except for anti-Ha/Pa activity also revealed additional anticoagulant and anti-inflammatory properties of enoxaparin sodium both in healthy people and patients, and in animal models. This includes AT-W-dependent inhibition of other clotting factors, such as factor Y 11a, activation of the release of the tissue factor pathway inhibitor (PTF), and reduction of the release of von Willebrand factor from the vascular endothelium into the bloodstream. These factors contribute to the overall anticoagulant effect of enoxaparin sodium.

When used in prophylactic doses, it slightly changes the activated partial thromboplastin time (APTT), has virtually no effect on platelet aggregation and on the degree of binding of fibrinogen to platelet receptors.

Pharmacokinetics

Bioavailability and absorption

The absolute bioavailability of enoxaparin sodium with subcutaneous (subcutaneous) use, estimated on the basis of anti-Xa activity, is close to 100%. The average maximum anti-Xa activity in blood plasma is observed 3-5 hours after subcutaneous use and reaches approximately 0.2,0.4,1.0 and 1.3 anti-Xa IU / ml after a single subcutaneous use of the drug at a dosage of 20 mg,40 mg,1 mg / kg and 1.5 mg/kg. Intravenous bolus use of the drug at a dosage of 30 mg, accompanied by immediate subcutaneous use of the drug at a dosage of 1 mg / kg every 12 hours, provides the initial maximum anti-Xa activity at the level of 1.16 IU / ml (n=16), the average exposure of the drug in the blood is approximately 88% of the equilibrium state, which is reached on the second day of therapy.

The pharmacokinetics of enoxaparin sodium in these dosage regimens are linear. Variability within and between patient groups is low. After repeated subcutaneous use of 40 mg of enoxaparin sodium once a day and subcutaneous use of enoxaparin sodium at a dose of 1.5 mg/kg of body weight once a day in healthy volunteers, the equilibrium concentration is reached by day 2, and the area under the pharmacokinetic curve is on average 15% higher than after a single dose of 2 of 30 use. After repeated subcutaneous use of enoxaparin sodium at a daily dose of 1 mg/kg body weight twice a day, the equilibrium concentration is reached in 3-4 days, and the area under the pharmacokinetic curve (AUC) is on average 65% higher than after a single use, and the average values of maximum concentrations are 1.2 IU/ml and 0.52 IU/ml, respectively.

Anti-IIa activity in blood plasma is approximately 10 times lower than anti-Xa activity. The average maximum anti-Pa activity is observed approximately 3-4 hours after subcutaneous use and reaches 0.13 IU / ml and 0.19 IU / ml after repeated use of 1 mg/kg of body weight with a double use and 1.5 mg/kg of body weight with a single use, respectively.

Distribution

The volume of distribution of anti-Xa activity of enoxaparin sodium is approximately 4.3 liters and is close to the volume of circulating blood.

Deduction

Enoxaparin sodium is a low-clearance drug. After intravenous use for 6 hours at a dose of 1.5 mg/kg of body weight, the average plasma clearance of anti-Xa is 0.74 l / h. Elimination of the drug is monophasic with half-lives (T 1/2) of about 5 hours (after a single subcutaneous injection) and about 7 hours (after repeated use of the drug).

Enoxaparin sodium is mainly metabolized in the liver by desulfation and / or depolymerization to form low-molecular-weight substances with very low biological activity. Renal excretion of active fragments of the drug is approximately 10% of the administered dose, and the total excretion of active and inactive fragments is approximately 40% of the administered dose.

Special patient groups

Elderly patients (over 75 years of age): the pharmacokinetic profile of enoxaparin sodium does not differ in elderly patients and younger patients with normal renal function. However, as a result of decreased renal function with age, there may be a slowdown in the elimination of enoxaparin sodium in elderly patients. Hepatic impairment: in a study involving patients with advanced cirrhosis treated with enoxaparin sodium at a dose of 4000 IU (40 mg) once a day, a decrease in maximum anti-Xa activity was associated with an increase in the severity of hepatic impairment (with a Child-Pugh score). This 3 out of 30 decrease was mainly due to a decrease in AT-III levels secondary to a decrease in AT-III synthesis in patients with impaired liver function.

Impaired renal function: decreased clearance of enoxaparin sodium was observed in patients with impaired renal function. After repeated subcutaneous use of 40 mg enoxaparin sodium once a day, anti-Xa activity is increased, represented by the area under the pharmacokinetic curve (AUC) in patients with mild renal impairment (creatinine clearance >50 and >80 ml / min) and moderate (creatinine clearance >30 and <80 ml / min) and moderate (creatinine clearance > In patients with severe renal impairment (CC

Hemodialysis: The pharmacokinetics of enoxaparin sodium were comparable to those in the control population after a single intravenous dose of 25 IU,50 IU or 100 IU / kg (0.25,0.50 or 1.0 mg/kg), but the AUC was twice as high as in the control population.

Body weight: after repeated subcutaneous use at a dose of 1.5 mg / kg once a day, the average AUC of anti-Xa activity at equilibrium is slightly higher in overweight patients (BMI 30-48 kg/m2) compared to patients with normal average body weight, while the maximum anti-Xa activity in blood plasma does not increase. In overweight patients, subcutaneous use of the drug has a slightly lower clearance. If no dose adjustment is made for the patient’s body weight, then after a single subcutaneous injection of 40 mg of enoxaparin sodium, anti-Xa activity will be 52% higher in women with a body weight of less than 45 kg and 27% higher in men with a body weight of less than 57 kg compared to patients with a normal average body weight.

Indications

Prevention of venous thrombosis and embolism during surgical interventions in moderate and high-risk patients, especially in orthopedic and general surgical interventions, including cancer.

Prevention of venous thrombosis and embolism in patients on bed rest due to acute therapeutic diseases, including acute heart failure and decompensation of chronic heart failure (NYHA Class III or IV), respiratory failure, as well as in severe infections and rheumatic diseases with an increased risk of venous thrombosis.

Treatment of deep vein thrombosis with or without pulmonary embolism, except in cases of pulmonary embolism requiring thrombolytic therapy or surgery.

Prevention of thrombosis in the extracorporeal circulatory system during hemodialysis.

Acute coronary syndrome:

– Treatment of unstable angina and non-ST-segment elevation myocardial infarction in combination with oral acetylsalicylic acid. – Treatment of acute ST – segment elevation myocardial infarction in patients undergoing medical treatment or subsequent percutaneous coronary intervention (PCI).

Use during pregnancy and lactation

There is no evidence that enoxaparin sodium penetrates the placental barrier during pregnancy. Since there are no adequate and well-controlled studies involving pregnant women, and animal studies do not always predict a response to the introduction of enoxaparin sodium during pregnancy in humans, it should be used during pregnancy only in exceptional cases, when there is an urgent need for its use, established by a doctor.

It is recommended to monitor the condition of patients for signs of bleeding or excessive anticoagulation, patients should be warned about the risk of bleeding.

There is no evidence of an increased risk of bleeding, thrombocytopenia, or osteoporosis in pregnant women, except in patients with artificial heart valves.

When planning epidural anesthesia, it is recommended to cancel enoxaparin sodium before it is performed.

Breast-feeding period

It is not known whether unchanged enoxaparin sodium is excreted in breast milk. Absorption of enoxaparin sodium in the gastrointestinal tract in a newborn is unlikely. Clexan® can be used during breastfeeding.

Recommendations for use

Features of drug use:

The pre-filled disposable syringe is ready for use.

The drug should not be administered intramuscularly!

Subcutaneous use:

Injections should preferably be performed in the patient’s “lying down” position. When using pre-filled 20 mg and 40 mg syringes, do not remove air bubbles from the syringe before injection to avoid drug loss. Injections should be performed alternately in the left or right anterolateral or posterolateral surface of the abdomen.

The needle should be inserted at full length, vertically (not laterally), into the skin fold, collected and held until the injection is completed between the thumb and index finger. The skin fold is released only after the injection is completed. Do not massage the injection site after use of the drug.

Intravenous bolus use:

Intravenous bolus use of enoxaparin sodium should be performed through a venous catheter. Enoxaparin sodium should not be mixed or administered together with other medicinal products. In order to avoid the presence of traces of other drugs in the infusion system and their interaction with enoxaparin sodium, the venous catheter should be flushed with a sufficient amount of 0.9% sodium chloride solution or 5% dextrose solution before and after intravenous bolus use of enoxaparin sodium. Enoxaparin sodium can be safely administered with 0.9% sodium chloride solution and 5% dextrose solution.

For bolus use of 30 mg of enoxaparin sodium in the treatment of acute ST-segment elevation myocardial infarction, an excess amount of the drug is removed from glass syringes of 60 mg,80 mg and 100 mg so that only 30 mg (0.3 ml) remains in them. A dose of 30 mg can be directly administered intravenously.

For intravenous bolus use of enoxaparin sodium through a venous catheter, pre-filled syringes for subcutaneous use of the drug 60 mg,80 mg and 100 mg can be used. It is recommended to use syringes of 60 mg, as this reduces the amount of drug removed from the syringe. 20 mg syringes are not used, as they do not contain enough preparation for bolus use of 30 mg of enoxaparin sodium. Syringes of 40 mg are not used, as they do not have divisions and therefore it is impossible to accurately measure the amount of 30 mg. To increase the accuracy of additional intravenous bolus use of small volumes into a venous catheter during percutaneous coronary interventions, it is recommended to dilute the drug to a concentration of 3 mg / ml. Dilution of the solution is recommended immediately before use.

To obtain a 3 mg/ml enoxaparin sodium solution using a pre-filled 60 mg syringe, it is recommended to use a 50 ml infusion container (i. e. with 0.9% sodium chloride solution or 5% dextrose solution).30 ml of the solution is extracted and removed from the container with the infusion solution using a conventional syringe. Enoxaparin sodium (the contents of the hypodermic syringe 60 mg) is injected into the remaining 20 ml of the infusion solution in the container. The contents of the container with a diluted solution of enoxaparin sodium are carefully mixed. For use with a syringe, the required volume of diluted enoxaparin sodium solution is extracted, which is calculated by the formula:

Volume of diluted solution = Patient’s body weight (kg) x 0.1

Contraindications

Interaction

Clexan® should not be mixed with other medications!

Not recommended combinations:

Drugs that affect hemostasis (systemic salicylates, acetylsalicylic acid in doses that have an anti-inflammatory effect, nonsteroidal anti-inflammatory drugs (NSAIDs), including ketorolac, other thrombolytics (alteplase, reteplase, streptokinase, tenecteplase, urokinase)) are recommended to be discontinued before starting therapy with enoxaparin sodium. If concomitant use with enoxaparin sodium is necessary, caution should be exercised and careful clinical monitoring and monitoring of appropriate laboratory parameters should be carried out.

Combinations that require caution

Other medications that affect hemostasis, such as:

– inhibitors of platelet aggregation, including acetylsalicylic acid in doses that have an antiplatelet effect (cardioprotection), clopidogrel, ticlopidine and antagonists of glycoprotein IIb/IIIa receptors, indicated in acute coronary syndrome, due to an increased risk of bleeding;

– dextran with a molecular weight of 40 kDa;

– systemic glucocorticosteroids.

Medicinal products that increase the potassium content When used simultaneously with medicinal products that increase the potassium content in the blood serum, clinical and laboratory monitoring should be carried out.

How to take, course of use and dosage

Subcutaneously, except in special cases.

Prevention of venous thrombosis and embolism during surgical interventions in moderate and high-risk patients.

In patients with a moderate risk of developing thrombosis and embolism (for example, abdominal surgery), the recommended dose of Klexan® is 20 mg once a day subcutaneously. The first injection should be given 2 hours before surgery.

Patients with a high risk of developing thrombosis and embolism (for example, during orthopedic operations, surgical operations in oncology, patients with additional risk factors not related to surgery, such as congenital or acquired thrombophilia, malignancy, bed rest for more than three days, obesity, a history of venous thrombosis, varicose veins of the lower extremities, pregnancy), the drug is recommended at a dose of 40 mg once a day subcutaneously, with the first dose administered 12 hours before surgery. If earlier preoperative prophylaxis is necessary (for example, in patients at high risk of developing thrombosis and thromboembolism awaiting delayed orthopedic surgery), the last injection should be made 12 hours before surgery and 12 hours after surgery.

The average duration of treatment with Klexan® is 7-10 days. If necessary, therapy can be continued as long as there is still a risk of developing thrombosis and embolism, and until the patient switches to outpatient mode.

For major orthopedic surgeries, it may be advisable to continue treatment after initial therapy by administering the drug at a dose of 40 mg once a day for five weeks.

For patients at high risk of venous thromboembolism who have undergone surgery, abdominal and pelvic surgery due to cancer, it may be advisable to increase the duration of use of Klexan® at a dose of 40 mg once a day for four weeks.

Prevention of venous thrombosis and embolism in patients on bed rest due to acute therapeutic diseases The recommended dose of Klexan® is 40 mg once a day, subcutaneously, for 6-14 days. Therapy should be continued until the patient is completely switched to outpatient mode (maximum for 14 days).

Treatment of deep vein thrombosis with or without pulmonary embolism

The drug is administered subcutaneously at the rate of 1.5 mg / kg of body weight once a day or 1 mg / kg of body weight twice a day. The dosage regimen should be selected by the doctor based on an assessment of the risk of thromboembolism and the risk of bleeding. In patients without thromboembolic complications and with a low risk of venous thromboembolism, the drug is recommended to be administered subcutaneously at the rate of 1.5 mg/kg of body weight once a day. In all other patients, including those with obesity, symptomatic pulmonary embolism, cancer, recurrent venous thromboembolism and proximal thrombosis (in the iliac vein), the drug is recommended to be used at a dose of 1 mg/kg twice a day. The average duration of treatment is 10 days. Indirect anticoagulant therapy should be initiated immediately, and treatment with Klexan® should be continued until the therapeutic anticoagulant effect is achieved (INR values should be 2.0-3.0).

Prevention of thrombosis in the extracorporeal circulatory system during hemodialysis

The recommended dose of Klexan® is on average 1 mg / kg of body weight. If there is a high risk of bleeding, the dose should be reduced to 0.5 mg / kg of body weight with double vascular access or to 0.75 mg / kg with single vascular access.

During hemodialysis, Clexan® should be inserted into the arterial section of the shunt at the beginning of the hemodialysis session. One dose is usually sufficient for a four-hour session, but if fibrin rings are detected during longer hemodialysis, the drug can be additionally administered at the rate of 0.5-1 mg/kg of body weight. There are no data available for patients using enoxaparin sodium for prevention or treatment and during hemodialysis sessions.

Treatment of unstable angina and non-ST-segment elevation myocardial infarction Clexan® is administered at the rate of 1 mg/kg of body weight every 12 hours, subcutaneously, with simultaneous use of antiplatelet therapy. The average duration of therapy is at least 2 days and continues until the patient’s clinical condition stabilizes. Usually, the drug use lasts from 2 to 8 days. Acetylsalicylic acid is recommended for all patients who do not have contraindications, with an initial dose of 150-300 mg orally followed by a maintenance dose of 75-325 mg once a day.

Treatment of acute ST-segment elevation myocardial infarction, medication or percutaneous coronary intervention Treatment begins with a single intravenous bolus injection of enoxaparin sodium at a dose of 30 mg. Immediately after it, enoxaparin sodium is administered subcutaneously at a dose of 1 mg/kg of body weight. Next, the drug is administered subcutaneously at 1 mg / kg of body weight every 12 hours (maximum 100 mg of enoxaparin sodium for each of the first two subcutaneous injections, then-1 mg/kg of body weight for the remaining subcutaneous doses, that is, with a body weight of more than 100 kg, a single dose can not exceed 100 mg). As soon as possible after detection of acute ST-segment elevation myocardial infarction, patients should be prescribed acetylsalicylic acid simultaneously and, if there are no contraindications, acetylsalicylic acid (in doses of 75-325 mg) should be continued daily for at least 30 days.

The recommended duration of treatment with Klexan® is 8 days or until the patient is discharged from the hospital (if the period of hospitalization is less than 8 days).

When combined with thrombolytics (fibrin-specific and fibrin-non-specific), enoxaparin sodium should be administered in the interval from 15 minutes before the start of thrombolytic therapy and up to 30 minutes after it.

In patients aged 75 years and older, the initial intravenous bolus is not used. The drug is administered subcutaneously at a dose of 0.75 mg / kg every 12 hours (maximum 75 mg of enoxaparin sodium for each of the first two subcutaneous injections, then 0.75 mg/kg of body weight for the remaining subcutaneous doses, that is, with a body weight of more than 100 kg, a single dose can not exceed 75 mg).

In patients undergoing percutaneous coronary intervention, if the last subcutaneous injection of enoxaparin sodium was performed less than 8 hours before inflating the balloon catheter inserted into the site of narrowing of the coronary artery, additional use of enoxaparin sodium is not required. If the last subcutaneous injection of enoxaparin sodium was performed more than 8 hours before inflating the balloon catheter, an additional intravenous bolus of enoxaparin sodium should be administered at a dose of 0.3 mg / kg.

Overdose

Accidental overdose of Clexan® with intravenous, extracorporeal or subcutaneous use may lead to hemorrhagic complications. When taken orally, even large doses of the drug are unlikely to be absorbed.

Anticoagulant effects can mainly be neutralized by slow intravenous use of protamine sulfate, the dose of which depends on the dose of the drug administered. One mg (1 mg) of protamine sulfate neutralizes the anticoagulant effect of one mg (1 mg) of Clexan® (see information on the use of protamine sulfate preparations), if enoxaparin sodium was administered no more than 8 hours before protamine use. 0.5 mg of protamine neutralizes the anticoagulant effect of 1 mg of the drug, if more than 8 hours have passed since the last dose was administered, or if a second dose of protamine is necessary. If 12 hours or more have passed since the introduction of enoxaparin sodium, the introduction of protamine is not required. However, even with high doses of protamine sulfate, the anti-Xa activity of Clexan® is not completely neutralized (by a maximum of 60%).

Description

Clear, colorless to pale yellow solution.

Special instructions

General information

Low-molecular-weight heparins are not interchangeable, as they differ in the production process, molecular weight, specific anti-Xa activity, dosage units and dosage regimen, which are associated with differences in their pharmacokinetics and biological activity (antithrombin activity and platelet interaction). Therefore, it is necessary to strictly follow the recommendations for use for each drug belonging to the class of low-molecular-weight heparins.

Bleeding

As with other anticoagulants, the use of Clexan® may cause bleeding of any localization

If bleeding develops, it is necessary to find its source and prescribe appropriate treatment.

Enoxaparin sodium, like other anticoagulants, should be used with caution in conditions with an increased risk of bleeding, such as::

– hemostatic disorders;- a history of peptic ulcer disease; – a recent ischemic stroke;- severe arterial hypertension; – diabetic retinopathy; – neurosurgical or ophthalmic surgery;- simultaneous use of drugs that affect hemostasis

Bleeding in elderly patients

When using enoxaparin sodium in prophylactic doses in elderly patients, there was no increase in the risk of bleeding.

When using the drug in therapeutic doses in elderly patients (especially at the age of 80 years and older), there is an increased risk of bleeding. Careful monitoring of these patients is recommended

Simultaneous use of other drugs that affect hemostasis. The use of drugs that affect hemostasis (salicylates of systemic action, including acetylsalicylic acid in doses that have an anti-inflammatory effect, NSAIDs, including ketorolac, other thrombolytics (alteplase, reteplase, streptokinase, tenecteplase, urokinase)) is recommended to be discontinued before starting treatment with enoxaparin sodium, except in cases where their use is necessary. If their simultaneous use with enoxaparin sodium is indicated, then careful clinical monitoring and monitoring of appropriate laboratory parameters should be carried out.

Kidney failure

Patients with impaired renal function have an increased risk of bleeding as a result of increased systemic exposure to enoxaparin sodium. In patients with severe renal impairment (creatinine clearance >15 and > Although no dose adjustment is required in patients with mild (creatinine clearance >30 and ><50 ml/min) and moderate (creatinine clearance >50 and <50 ml/min) and moderate (creatinine clearance > Enoxaparin sodium is not recommended for patients with end-stage chronic kidney disease (CC).

Low body weight

There was an increase in exposure to enoxaparin sodium with its preventive use in women with a body weight of less than 45 kg and in men with a body weight of less than 57 kg, which may lead to an increased risk of bleeding. Careful monitoring of these patients is recommended.

Obese patients

Obese patients have an increased risk of developing thrombosis and embolism. The safety and efficacy of enoxaparin sodium in prophylactic doses in obese patients (BMI greater than 30 kg / m2) is not fully defined and there is no consensus on dose adjustment.It is recommended to monitor patients for the development of symptoms and signs of thrombosis and embolism.

Control of the number of platelets in the peripheral blood.

The risk of developing antibody-mediated heparin-induced thrombocytopenia (GIT) also exists with the use of low-molecular-weight heparins, and this risk is higher in patients who have undergone heart surgery and patients with cancer. If thrombocytopenia develops, it is usually detected between 5 and 21 days after the start of enoxaparin sodium therapy. In this regard, it is recommended to regularly monitor the number of platelets in the peripheral blood before starting treatment with enoxaparin sodium and during its use. The blood platelet count should be determined if there are symptoms that indicate GIT (a new episode of arterial and / or venous thromboembolic complications, painful skin damage at the injection site, allergic or anaphylactic reaction during treatment). If these symptoms occur, you should inform your doctor. If there is a confirmed significant decrease in platelet count (by 30-50% compared to baseline), enoxaparin sodium should be immediately discontinued and the patient should be transferred to another anticoagulant therapy without the use of heparins.

Spinal / epidural anesthesia

Cases of occurrence of neuroaxial hematomas with enoxaparin sodium and simultaneous spinal/epidural anesthesia with the development of long-term or irreversible paralysis are described. The risk of these events is reduced when the drug is administered at a dose of 40 mg or lower. The risk increases with higher doses of enoxaparin sodium, as well as with the use of permanent catheters after surgery, or with the simultaneous use of additional drugs that affect hemostasis, such as NSAIDs. The risk is also increased with traumatic or repeated spinal puncture, or in patients with a history of spinal surgery or spinal deformity.

To reduce the possible risk of bleeding associated with the use of enoxaparin sodium and epidural or spinal anesthesia/analgesia, the pharmacokinetic profile of the drug should be taken into account (see the section “Pharmacokinetics”). Catheter insertion or removal is best performed when the anticoagulant effect of enoxaparin sodium is low, but the exact time to achieve a sufficient reduction in the anticoagulant effect in different patients is unknown. It should also be taken into account that in patients with creatinine clearance of 15-30 ml/min, the elimination of enoxaparin sodium slows down.

If the doctor prescribes anticoagulant therapy during epidural / spinal anesthesia or lumbar puncture, the patient should be constantly monitored for any neurological symptoms, such as back pain, impaired sensory and motor functions (numbness or weakness in the lower extremities), impaired bowel and/or bladder function. The patient should be instructed to inform the doctor immediately if the symptoms described above occur. If symptoms that are characteristic of a spinal cord hematoma are suspected, urgent diagnosis and treatment are required, including, if necessary, spinal cord decompression.
