Teva Pharmaceutical Industries Ltd. has launched the generic equivalent of the low-molecular-weight heparin Lovenox (enoxaparin sodium injection) in 7 dosage strengths in the US.
Enoxaparin can be used to prevent deep vein thrombosis (DVT) in patients undergoing abdominal surgery, those receiving a hip or knee replacement, and patients at risk of thromboembolic complications due to severely restricted mobility during acute illness.
When administered with warfarin, enoxaparin can be used for inpatient treatment of acute DVT, with or without pulmonary embolism (PE). Enoxaparin given in conjunction with warfarin may also be used for outpatient treatment of acute DVT without PE.
When given concurrently with aspirin, enoxaparin can be used to prevent ischemic complications of unstable angina and non-Q-wave myocardial infarction. Enoxaparin may also be used to treat acute ST-segment elevation myocardial infarction that is managed medically or with subsequent percutaneous coronary intervention.
Teva’s Enoxaparin Sodium Injection USP is available in the following doses:
- 30 mg/0.3 mL syringe, 10 x 0.3 mL
- 40 mg/0.4 mL syringe, 10 x 0.4 mL
- 60 mg/0.6 mL syringe, 10 x 0.6 mL
- 80 mg/0.8 mL syringe, 10 x 0.8 mL
- 100 mg/mL syringe, 10 x 1 mL
- 120 mg/0.8 mL syringe, 10 x 0.8 mL
- 150 mg/mL syringe, 10 x 1 mL.
Safety information
Enoxaparin’s label contains a boxed warning detailing the risk of epidural or spinal hematomas that can occur in patients who are anticoagulated with low-molecular-weight heparins or heparinoids and are receiving neuraxial anesthesia or undergoing spinal puncture. The hematomas may result in long-term or permanent paralysis.
Enoxaparin is contraindicated in patients with active major bleeding, thrombocytopenia with a positive in vitro test for antiplatelet antibody in the presence of enoxaparin, or known hypersensitivity to enoxaparin, heparin, or pork products.
Serious adverse reactions reported with enoxaparin include increased risk of hemorrhage and thrombocytopenia.
Enoxaparin should be used with extreme caution in patients who have conditions with an increased risk of hemorrhage or in patients treated concomitantly with platelet inhibitors. Major hemorrhages, including retroperitoneal and intracranial bleeding, have been reported with enoxaparin. Some of these cases have been fatal.
Bleeding can occur at any site during enoxaparin treatment. The drug should be used with care in patients with a bleeding diathesis, uncontrolled arterial hypertension, or a history of recent gastrointestinal ulceration, diabetic retinopathy, renal dysfunction, and hemorrhage.
In clinical trials, the most common adverse reactions associated with enoxaparin (occurring in more than 1% of patients) were bleeding, anemia, thrombocytopenia, elevation of serum aminotransferase, diarrhea, and nausea. Mild local irritation, pain, hematoma, ecchymosis, and erythema may follow subcutaneous injection.
