Pharmacological action of
Enoxaparin sodium is a low molecular weight heparin with an average molecular weight of about 4,500 daltons (Yes): less than 2000 Da - <20%, from 2000 to 8000 Yes -> 68%, more than 8000 Yes - <18%. Enoxaparin sodium is obtained by alkaline hydrolysis of heparin benzyl ester isolated from the mucous membrane of the pig’s small intestine. Its structure is characterized by a non-reducing fragment of 2-O-sulfo-4-enpyrazinosuronic acid and a recovering fragment of 2-N, 6-O-disulfo-D-glucopyranoside. The structure of enoxaparin sodium contains about 20% (ranging from 15% to 25%) 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-III), providing anticoagulant activity in humans. In addition to anti-Xa / IIa activity, additional anticoagulant and anti-inflammatory properties of enoxaparin sodium were also detected in healthy people and patients, as well as in animal models. This includes AT-III-dependent inhibition of other coagulation factors, such as factor VIIa, activation of the release of the tissue factor pathway inhibitor (PTF), as well as a decrease in the release of von Willebrand factor from the vascular endothelium into the bloodstream. These factors provide the anticoagulant effect of enoxaparin sodium in general.
When used in prophylactic doses, it slightly changes the activated partial thromboplastin time (APTT) and has practically no effect on platelet aggregation and the degree of binding of fibrinogen to platelet receptors.
Pharmacokinetics:
Bioavailability and absorption of
The absolute bioavailability of enoxaparin sodium when administered subcutaneously (s / c), based on anti-Xa activity, is close to 100%.
The average maximum anti-XA activity in blood plasma is observed 3-5 hours after s / c administration and reaches approximately 0.2, 0.4, 1.0 and 1.3 anti-XA ME / ml after a single s / c administration of the drug in a dosage of 20 mg, 40 mg, 1 mg / kg and 1.5 mg / kg.
Intravenous bolus administration of the drug at a dose of 30 mg, accompanied by immediate subcutaneous administration of the drug at a dose of 1 mg / kg every 12 hours, provides an initial maximum anti-Xa activity of 1.16 IU / ml (n = 16), the average exposure in blood is approximately 88% of the equilibrium state, which is achieved on the second day of therapy.
The pharmacokinetics of enoxaparin in these dosing regimens is linear. Variability within and between patient groups is low.
After subcutaneous administration of 40 mg of enoxaparin sodium once a day and subcutaneous administration of enoxaparin sodium at a dose of 1.5 mg / kg body weight once a day in healthy volunteers, the equilibrium concentration is reached by day 2, and the average area under the pharmacokinetic curve is 15% higher than after a single injection.
After repeated subcutaneous injections of enoxaparin sodium in a daily dose of 1 mg / kg body weight twice a day, the equilibrium concentration is reached after 3-4 days, and the area under the pharmacokinetic curve (AUC) is on average 65% higher than after a single injection, and average maximum concentrations are 1.2 IU / ml and 0.52 IU / ml, respectively.
Anti-IIa plasma activity is about 10 times lower than anti-Xa activity. The average maximum anti-IIa activity is observed approximately 3-4 hours after subcutaneous administration and reaches 0.13 IU / ml and 0.19 IU / ml after repeated administration of 1 mg / kg of body weight with double administration and 1.5 mg / kg body weight with a single administration, respectively.
Distribution of
The volume of distribution of the anti-Xa activity of enoxaparin sodium is approximately 4.3 L and approaches the volume of circulating blood.
Excretion
Enoxaparin sodium is a low-clearance drug. After intravenous administration for 6 hours at a dose of 1.5 mg / kg body weight, the average anti-Xa clearance in plasma is 0.74 l / h.
Withdrawal of the drug is monophasic with a half-life (T1 / 2) of about 5 hours (after a single subcutaneous injection) and about 7 hours (after repeated administration 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. Excretion of active fragments of the drug through the kidneys 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): the pharmacokinetic profile of enoxaparin sodium is not different in elderly patients and younger patients with normal renal function. However, a decrease in renal function with age may result in a slowdown in the elimination of enoxaparin sodium in elderly patients.
Dysfunction of the liver: in a study involving patients with advanced liver cirrhosis who received enoxaparin sodium at a dosage of 4000 ME (40 mg) once a day, a decrease in maximum anti-Xa activity was associated with an increase in the severity of liver dysfunction (with a Child-Pugh score). This decrease was mainly due to a decrease in the level of AT-III, secondary to a decrease in the synthesis of AT-III in patients with impaired liver function.
Impaired renal function: a decrease in clearance of enoxaparin sodium was noted in patients with impaired renal function. After repeated subcutaneous administration of 40 mg enoxaparin sodium once a day, there is an increase in anti-XA activity, represented by the area under the pharmacokinetic curve (AUC) in patients with impaired renal function of the lung (creatinine clearance (CC) 50-80 ml / min) and moderate severity (CC 30-50 ml / min). In patients with severe renal impairment (CC less than 30 ml / min), AUC in equilibrium is on average 65% higher with repeated subcutaneous administration of 40 mg of the drug once a day.
Hemodialysis: the pharmacokinetics of enoxaparin sodium is comparable to that in the control population after a single iv dose of 25 IU, 50 IU or 100 IU / kg (0.25, 0.50 or 1.0 mg / kg), but there were two AUC times higher than in the control population.
Body weight: after repeated sc administration at a dose of 1.5 mg / kg once a day, the average AUC of anti-Xa activity in equilibrium is slightly higher in patients with overweight (BMI 30-48 kg / m2) compared with patients with normal average body weight, while the maximum anti-Xa activity of blood plasma does not increase. In patients with excess body weight with subcutaneous administration of the drug, clearance is somewhat less. If you do not adjust the dose taking into account 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 with patients with normal average body weight.

Active ingredient:
enoxaparin sodium 60 mg
Excipients:
water for injection - up to 0.6 ml.
Dosage and Administration
Subcutaneously, except in special cases.
Prevention of venous thrombosis and embolism during surgical interventions in patients with moderate to high risk
For patients with a moderate risk of developing thrombosis and embolism (for example, abdominal surgery), the recommended dose of Enixum® is 20 mg once daily subcutaneously. The first injection should be made 2 hours before surgery.
Patients at high risk of developing thrombosis and embolism (for example, during orthopedic surgeries, surgical operations in oncology, patients with additional risk factors not related to surgery, such as congenital or acquired thrombophilia, malignant neoplasm, bed rest for more than three days, obesity, 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 introduction of the first dose 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 given 12 hours before surgery and 12 hours after surgery.
The duration of treatment with Enixum is on average 7-10 days. If necessary, therapy can be continued until the risk of thrombosis and embolism remains, and until the patient switches to an outpatient setting.
For major orthopedic surgeries, it may be advisable after initial therapy to continue treatment by administering the drug Enixum® at a dose of 40 mg once a day for five weeks.
For patients at high risk of venous thromboembolism who underwent surgery, abdominal and pelvic surgery due to cancer, it may be advisable to increase the duration of administration of the drug Enixum® 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 Enixum® is 40 mg once a day, subcutaneously, for 6-14 days. Therapy should be continued until the patient has completely switched to an outpatient regimen (for a maximum of 14 days).
Treatment of deep vein thrombosis with pulmonary thromboembolism or without pulmonary thromboembolism
The drug is administered subcutaneously at a rate of 1.5 mg / kg body weight once a day or 1 mg / kg body weight twice a day. The dosage regimen should be selected by the physician 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 developing venous thromboembolism, the drug is recommended to be administered subcutaneously at a rate of 1.5 mg / kg body weight once a day.
In all other patients, including patients with obesity, symptomatic pulmonary embolism, cancer, repeated 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.
Duration of treatment is on average 10 days. Indirect anticoagulant therapy should be started immediately, and treatment with Enixum® should be continued until the therapeutic anticoagulant effect is achieved (INR [International Normalized Relationship] values should be 2.0-3.0).
Prevention of thrombosis in the extracorporeal circulatory system during hemodialysis
The recommended dose of Enixum® is on average 1 mg / kg body weight. With a high risk of bleeding, the dose should be reduced to 0.5 mg / kg body weight with double vascular access or 0.75 mg / kg with a single vascular access.
During hemodialysis, Enixum® should be administered into the arterial area of the shunt at the beginning of the hemodialysis session. One dose, as a rule, is enough for a four-hour session, however, if fibrin rings are detected with longer hemodialysis, you can additionally introduce the drug at a rate of 0.5-1 mg / kg body weight. Data on patients using enoxaparin sodium for prophylaxis or treatment and during hemodialysis sessions are not available.
Treatment of unstable angina pectoris and myocardial infarction without raising the ST segment
Enixum® is administered at a rate of 1 mg / kg 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, drug administration lasts from 2 to 8 days.
Acetylsalicylic acid is recommended for all patients who have no contraindications, with an initial dose of 150-300 mg orally, followed by a maintenance dose of 75-325 mg once in knocking.
Treatment of acute myocardial infarction with ST-segment elevation, medication or with percutaneous coronary intervention
Treatment begins with a single intravenous bolus of enoxaparin sodium at a dose of 30 mg. Immediately after it, enoxaparin sodium is administered subcutaneously at a dose of 1 mg / kg body weight. Further, the drug is administered subcutaneously at 1 mg / kg 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 single dose may not exceed 100 mg).
As soon as possible after the detection of acute myocardial infarction with ST segment elevation, patients should be prescribed acetylsalicylic acid at the same time 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 Enixum® is 8 days or until the patient is discharged from the hospital (if the hospitalization period is less than 8 days).
When combined with thrombolytics (fibrin-specific and fibrin-non-specific), enoxaparin sodium should be administered between 15 minutes before starting thrombolytic therapy and 30 minutes after it.
In patients 75 years of age 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 cannot exceed 75 mg).
In patients undergoing percutaneous coronary intervention, if the last subcutaneous injection of enoxaparin sodium was performed less than 8 hours before the balloon catheter was introduced into the site of the coronary artery narrowing, additional administration of enoxaparin sodium is not required. If the last subcutaneous injection of enoxaparin sodium was carried out more than 8 hours before the balloon catheter was inflated, an additional intravenous bolus injection of enoxaparin sodium at a dose of 0.3 mg / kg should be performed.
Side effects of
The side effects of enoxaparin sodium were studied in more than 15,000 patients who participated in clinical trials, of which 1776 patients prevented venous thrombosis and embolism during general and orthopedic operations in 1169 patients and prevented venous venous thrombosis patients in bed rest due to acute therapeutic diseases in 559 patients - in the treatment of deep vein thrombosis with pulmonary embolism or without pulmonary embolism in 1578 patients - in the treatment of unstable angina and myocardial infarction without Q wave in 10176 patients - in the treatment of elevated myocardial infarction ST segment.
Enoxaparin sodium administration regimen was different depending on the indication. In the prevention of venous thrombosis and embolism during general surgical and orthopedic operations or in patients on bed rest, 40 mg was administered subcutaneously once a day.

Disorders of the nervous system:
often: headache.
Vascular disorders:

Overdose of
Accidental overdose of enoxaparin sodium with intravenous, extracorporeal or subcutaneous administration can lead to hemorrhagic complications. When ingesting even large doses, absorption of the drug is unlikely.
Anticoagulant effects can be largely neutralized by slow intravenous administration 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 enoxaparin sodium (see information on the use of protamine salts) if enoxaparin sodium was administered no more than 8 hours before the administration of protamine. 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 injection or, if necessary, the introduction of a second dose of protamine. If 12 hours or more have passed after the administration of enoxaparin sodium, administration of protamine is not required. However, even with the introduction of large doses of protamine sulfate, anti-Xa, the activity of enoxaparin sodium is not completely neutralized (by a maximum of 60%).

Enoxaparin sodium is a low molecular weight heparin with an average molecular weight of about 4,500 daltons (Yes): less than 2000 Da - <20%, from 2000 to 8000 Yes -> 68%, more than 8000 Yes - <18%. Enoxaparin sodium is obtained by alkaline hydrolysis of heparin benzyl ester isolated from the mucous membrane of the pig’s small intestine. Its structure is characterized by a non-reducing fragment of 2-O-sulfo-4-enpyrazinosuronic acid and a recovering fragment of 2-N, 6-O-disulfo-D-glucopyranoside. The structure of enoxaparin sodium contains about 20% (ranging from 15% to 25%) 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-III), providing anticoagulant activity in humans. In addition to anti-Xa / IIa activity, additional anticoagulant and anti-inflammatory properties of enoxaparin sodium were also detected in healthy people and patients, as well as in animal models. This includes AT-III-dependent inhibition of other coagulation factors, such as factor VIIa, activation of the release of the tissue factor pathway inhibitor (PTF), as well as a decrease in the release of von Willebrand factor from the vascular endothelium into the bloodstream. These factors provide the anticoagulant effect of enoxaparin sodium in general.
When used in prophylactic doses, it slightly changes the activated partial thromboplastin time (APTT) and has practically no effect on platelet aggregation and the degree of binding of fibrinogen to platelet receptors.
Pharmacokinetics:
Bioavailability and absorption of
The absolute bioavailability of enoxaparin sodium when administered subcutaneously (s / c), based on anti-Xa activity, is close to 100%.
The average maximum anti-XA activity in blood plasma is observed 3-5 hours after s / c administration and reaches approximately 0.2, 0.4, 1.0 and 1.3 anti-XA ME / ml after a single s / c administration of the drug in a dosage of 20 mg, 40 mg, 1 mg / kg and 1.5 mg / kg.
Intravenous bolus administration of the drug at a dose of 30 mg, accompanied by immediate subcutaneous administration of the drug at a dose of 1 mg / kg every 12 hours, provides an initial maximum anti-Xa activity of 1.16 IU / ml (n = 16), the average exposure in blood is approximately 88% of the equilibrium state, which is achieved on the second day of therapy.
The pharmacokinetics of enoxaparin in these dosing regimens is linear. Variability within and between patient groups is low.
After subcutaneous administration of 40 mg of enoxaparin sodium once a day and subcutaneous administration of enoxaparin sodium at a dose of 1.5 mg / kg body weight once a day in healthy volunteers, the equilibrium concentration is reached by day 2, and the average area under the pharmacokinetic curve is 15% higher than after a single injection.
After repeated subcutaneous injections of enoxaparin sodium in a daily dose of 1 mg / kg body weight twice a day, the equilibrium concentration is reached after 3-4 days, and the area under the pharmacokinetic curve (AUC) is on average 65% higher than after a single injection, and average maximum concentrations are 1.2 IU / ml and 0.52 IU / ml, respectively.
Anti-IIa plasma activity is about 10 times lower than anti-Xa activity. The average maximum anti-IIa activity is observed approximately 3-4 hours after subcutaneous administration and reaches 0.13 IU / ml and 0.19 IU / ml after repeated administration of 1 mg / kg of body weight with double administration and 1.5 mg / kg body weight with a single administration, respectively.
Distribution of
The volume of distribution of the anti-Xa activity of enoxaparin sodium is approximately 4.3 L and approaches the volume of circulating blood.
Excretion
Enoxaparin sodium is a low-clearance drug. After intravenous administration for 6 hours at a dose of 1.5 mg / kg body weight, the average anti-Xa clearance in plasma is 0.74 l / h.
Withdrawal of the drug is monophasic with a half-life (T1 / 2) of about 5 hours (after a single subcutaneous injection) and about 7 hours (after repeated administration 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. Excretion of active fragments of the drug through the kidneys 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): the pharmacokinetic profile of enoxaparin sodium is not different in elderly patients and younger patients with normal renal function. However, a decrease in renal function with age may result in a slowdown in the elimination of enoxaparin sodium in elderly patients.
Dysfunction of the liver: in a study involving patients with advanced liver cirrhosis who received enoxaparin sodium at a dosage of 4000 ME (40 mg) once a day, a decrease in maximum anti-Xa activity was associated with an increase in the severity of liver dysfunction (with a Child-Pugh score). This decrease was mainly due to a decrease in the level of AT-III, secondary to a decrease in the synthesis of AT-III in patients with impaired liver function.
Impaired renal function: a decrease in clearance of enoxaparin sodium was noted in patients with impaired renal function. After repeated subcutaneous administration of 40 mg enoxaparin sodium once a day, there is an increase in anti-XA activity, represented by the area under the pharmacokinetic curve (AUC) in patients with impaired renal function of the lung (creatinine clearance (CC) 50-80 ml / min) and moderate severity (CC 30-50 ml / min). In patients with severe renal impairment (CC less than 30 ml / min), AUC in equilibrium is on average 65% higher with repeated subcutaneous administration of 40 mg of the drug once a day.
Hemodialysis: the pharmacokinetics of enoxaparin sodium is comparable to that in the control population after a single iv dose of 25 IU, 50 IU or 100 IU / kg (0.25, 0.50 or 1.0 mg / kg), but there were two AUC times higher than in the control population.
Body weight: after repeated sc administration at a dose of 1.5 mg / kg once a day, the average AUC of anti-Xa activity in equilibrium is slightly higher in patients with overweight (BMI 30-48 kg / m2) compared with patients with normal average body weight, while the maximum anti-Xa activity of blood plasma does not increase. In patients with excess body weight with subcutaneous administration of the drug, clearance is somewhat less. If you do not adjust the dose taking into account 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 with patients with normal average body weight.

Composition
1 syringe (0.6 ml) contains:
Active ingredient:
enoxaparin sodium 60 mg
Excipients:
water for injection - up to 0.6 ml.
Dosage and Administration
Subcutaneously, except in special cases.
Prevention of venous thrombosis and embolism during surgical interventions in patients with moderate to high risk
For patients with a moderate risk of developing thrombosis and embolism (for example, abdominal surgery), the recommended dose of Enixum® is 20 mg once daily subcutaneously. The first injection should be made 2 hours before surgery.
Patients at high risk of developing thrombosis and embolism (for example, during orthopedic surgeries, surgical operations in oncology, patients with additional risk factors not related to surgery, such as congenital or acquired thrombophilia, malignant neoplasm, bed rest for more than three days, obesity, 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 introduction of the first dose 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 given 12 hours before surgery and 12 hours after surgery.
The duration of treatment with Enixum is on average 7-10 days. If necessary, therapy can be continued until the risk of thrombosis and embolism remains, and until the patient switches to an outpatient setting.
For major orthopedic surgeries, it may be advisable after initial therapy to continue treatment by administering the drug Enixum® at a dose of 40 mg once a day for five weeks.
For patients at high risk of venous thromboembolism who underwent surgery, abdominal and pelvic surgery due to cancer, it may be advisable to increase the duration of administration of the drug Enixum® 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 Enixum® is 40 mg once a day, subcutaneously, for 6-14 days. Therapy should be continued until the patient has completely switched to an outpatient regimen (for a maximum of 14 days).
Treatment of deep vein thrombosis with pulmonary thromboembolism or without pulmonary thromboembolism
The drug is administered subcutaneously at a rate of 1.5 mg / kg body weight once a day or 1 mg / kg body weight twice a day. The dosage regimen should be selected by the physician 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 developing venous thromboembolism, the drug is recommended to be administered subcutaneously at a rate of 1.5 mg / kg body weight once a day.
In all other patients, including patients with obesity, symptomatic pulmonary embolism, cancer, repeated 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.
Duration of treatment is on average 10 days. Indirect anticoagulant therapy should be started immediately, and treatment with Enixum® should be continued until the therapeutic anticoagulant effect is achieved (INR [International Normalized Relationship] values should be 2.0-3.0).
Prevention of thrombosis in the extracorporeal circulatory system during hemodialysis
The recommended dose of Enixum® is on average 1 mg / kg body weight. With a high risk of bleeding, the dose should be reduced to 0.5 mg / kg body weight with double vascular access or 0.75 mg / kg with a single vascular access.
During hemodialysis, Enixum® should be administered into the arterial area of the shunt at the beginning of the hemodialysis session. One dose, as a rule, is enough for a four-hour session, however, if fibrin rings are detected with longer hemodialysis, you can additionally introduce the drug at a rate of 0.5-1 mg / kg body weight. Data on patients using enoxaparin sodium for prophylaxis or treatment and during hemodialysis sessions are not available.
Treatment of unstable angina pectoris and myocardial infarction without raising the ST segment
Enixum® is administered at a rate of 1 mg / kg 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, drug administration lasts from 2 to 8 days.
Acetylsalicylic acid is recommended for all patients who have no contraindications, with an initial dose of 150-300 mg orally, followed by a maintenance dose of 75-325 mg once in knocking.
Treatment of acute myocardial infarction with ST-segment elevation, medication or with percutaneous coronary intervention
Treatment begins with a single intravenous bolus of enoxaparin sodium at a dose of 30 mg. Immediately after it, enoxaparin sodium is administered subcutaneously at a dose of 1 mg / kg body weight. Further, the drug is administered subcutaneously at 1 mg / kg 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 single dose may not exceed 100 mg).
As soon as possible after the detection of acute myocardial infarction with ST segment elevation, patients should be prescribed acetylsalicylic acid at the same time 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 Enixum® is 8 days or until the patient is discharged from the hospital (if the hospitalization period is less than 8 days).
When combined with thrombolytics (fibrin-specific and fibrin-non-specific), enoxaparin sodium should be administered between 15 minutes before starting thrombolytic therapy and 30 minutes after it.
In patients 75 years of age 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 cannot exceed 75 mg).
In patients undergoing percutaneous coronary intervention, if the last subcutaneous injection of enoxaparin sodium was performed less than 8 hours before the balloon catheter was introduced into the site of the coronary artery narrowing, additional administration of enoxaparin sodium is not required. If the last subcutaneous injection of enoxaparin sodium was carried out more than 8 hours before the balloon catheter was inflated, an additional intravenous bolus injection of enoxaparin sodium at a dose of 0.3 mg / kg should be performed.
Side effects of
The side effects of enoxaparin sodium were studied in more than 15,000 patients who participated in clinical trials, of which 1776 patients prevented venous thrombosis and embolism during general and orthopedic operations in 1169 patients and prevented venous venous thrombosis patients in bed rest due to acute therapeutic diseases in 559 patients - in the treatment of deep vein thrombosis with pulmonary embolism or without pulmonary embolism in 1578 patients - in the treatment of unstable angina and myocardial infarction without Q wave in 10176 patients - in the treatment of elevated myocardial infarction ST segment.
Enoxaparin sodium administration regimen was different depending on the indication. In the prevention of venous thrombosis and embolism during general surgical and orthopedic operations or in patients on bed rest, 40 mg was administered subcutaneously once a day.
When treating deep vein thrombosis with or without pulmonary embolism, patients received enoxaparin sodium at a rate of 1 mg / kg body weight subcutaneously every 12 hours or 1, 5 mg / kg body weight subcutaneously once a day.
In the treatment of unstable angina pectoris and myocardial infarction without Q wave, the dose of sodium enoxaparin was 1 mg / kg body weight subcutaneously every 12 hours, and in the case of myocardial infarction with ST segment elevation, an intravenous bolus injection of 30 mg followed by 1 mg / kg body weight subcutaneously every 12 hours
The frequency of adverse reactions was determined according to the classification of the World Health Organization: very often ( 1/10) often ( 1/100 and <1/10) infrequently ( 1/1000 and <1/100 ) rarely ( 1/10000 and <1/1000) very rarely (<1/10000), frequencies unknown (can not be calculated on the basis of the available data).
