Noxarin

Enoxaparin Sodium is a low molecular weight heparin with a high anti-Xa activity and low anti-lla or antithrombin activity. At doses required for the various indications, Enoxaparin Sodium does not increase bleeding time. At preventive doses, Enoxaparin Sodium causes no notable modification of activated Partial Thromboplastin Time (aPTT). It neither influences platelet aggregation nor binding of fibrinogen to platelets. Enoxaparin Sodium is primarily metabolised in the liver.

It is recommended that agents which affect hemostasis should be discontinued prior to Enoxaparin Sodium therapy unless strictly indicated. These agents include medications such as: acetylsalicylic acid (and derivatives), NSAIDs (including ketorolac), ticlopidine,clopidogrel,dextran 40,glucocorticoids, thrombolytics and anticoagulants, other antiplatelet aggregation agents including glycoprotein llb/llla antagonists. If the combination is indicated, should be used with careful clinical and laboratory monitoring.

Haemorrhage (bleeding), Thrombocytopenia, elevations of serum aminotransferase. Pain, bluish marks at injection sites to skin rash at injection sites. Cases of neuraxial hematomas with the concurrent use of Enoxaparin and spinal/epidural anesthesia or spinal puncture have resulted in varying degrees of neurologic injuries.

Pregnancy category B. In humans, there is no evidence that Enoxaparin Sodium crosses the placental barrier. As there are no adequate and well-controlled studies in pregnant women, Enoxaparin Sodium should be used during pregnancy only if clearly needed. Pregnant women with mechanical prosthetic heart valves may be at a higher risk for thromboembolism.

It is not known whether Enoxaparin is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or discontinue Enoxaparin, taking into account the importance of Enoxaparin to the mother and the known benefits of nursing.

Enoxaparin Sodium should be injected by deep subcutaneous route in prophylactic and curative treatment and by intravascular route during hemodialysis. Do not administer by the intramuscular route. Enoxaparin Sodium should be used with caution in conditions with increased potential for bleeding, such as impaired hemostasis, history of peptic ulcer, recent ischemic stroke, uncontrolled severe arterial hypertension, diabetic retinopathy and recent neuro- or ophthalmologic surgery, concomitant use of medications affecting hemostasis. It is recommended that the platelet counts be measured before the initiation of the treatment and regularly thereafter during treatment.

Dose in Elderly Patients: No dosage adjustment is necessary, unless kidney function is impaired.

Dose in Renal Impairment: Although no dosage adjustment is recommended in patients with moderate (creatinine clearance: 30-50 ml/min) and mild (creatinine clearance: 50 80 ml/min) renal impairment, all such patients should be observed carefully for signs and symptoms of bleeding. For patients with severe (creatinine clearance <30 ml/min) renal impairment, following dosage adjustments are recommended: Prophylactic dose ranges: 2000 antiXa IU once daily; Therapeutic dose ranges: 100 anti-Xa lU/kg once daily.

Dose in Hepatic Impairment: Caution should be used in hepatically impaired patients.

Parenteral anti-coagulants

Accidental overdosage following administration of Enoxaparin may lead to hemorrhagic complications. Injected Enoxaparin may be largely neutralized by the slow i.v. injection of protamine sulfate (1% solution) The dose of protamine sulfate should be equal to the dose of Enoxaparin injected: 1 mg protamine sulfate should be administered to neutralize 1 mg Enoxaparin.

Store in a cool and dry place, protect from light and moisture. Do not store above 25°C. Do not store in a refrigerator or freezer. Keep out of the reach of children
