Ledraxen (Enoxaparin Sodium)

• Enoxaparin sodium is a low molecular weight heparin used to manage venous thromboembolism.
• Deep vein thrombosis (DVT) prevention: reduces clot formation in patients at risk of lower‑limb thrombosis.
• Pulmonary embolism (PE) treatment: facilitates clot resolution and prevents recurrence.
• Anticoagulation during hemodialysis: maintains circuit patency by inhibiting clotting.
• Surgical prophylaxis: lowers postoperative venous thromboembolism risk in orthopedic and general surgery patients.

• Enoxaparin sodium binds to antithrombin III, accelerating its inhibition of activated factor Xa and, to a lesser extent, factor IIa (thrombin). This selective blockade reduces thrombin generation and fibrin clot formation while preserving a degree of platelet function, providing anticoagulation with a predictable pharmacokinetic profile. The drug’s low molecular weight confers a higher anti‑Xa to anti‑IIa activity ratio, allowing subcutaneous administration with stable dose‑response and reduced monitoring requirements compared with unfractionated heparin.

Enoxaparin sodium may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Injection site bruising or hematoma
• Minor bleeding (e.g., gum, nosebleeds)
• Nausea or vomiting
• Headache

Serious or Rare Side Effects

• Major hemorrhage (internal or intracranial)
• Thrombocytopenia (heparin‑induced)
• Spinal or epidural hematoma
• Severe allergic reaction (anaphylaxis)

• When using Ledraxen, several precautions should be observed to minimize risk.
• Renal impairment: assess function and consider dose adjustment.
• Bleeding risk: evaluate for active bleeding or recent surgery before initiating.
• Concomitant anticoagulants: avoid or use with caution when combined with other anticoagulants or antiplatelet agents.
• Pregnancy: use only if benefit outweighs potential risk; data limited.
• Spinal/epidural procedures: discontinue before neuraxial anesthesia to reduce hematoma risk.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.
