Multiparin (Heparin Sodium)

Multiparin is an anticoagulant used in the management of thrombotic disorders and peri‑operative settings.

• Venous thromboembolism: prevents formation and propagation of clots in deep veins and pulmonary arteries.
• Deep‑vein thrombosis prophylaxis: reduces risk of clot development after surgery or immobilisation.
• Pulmonary embolism treatment: facilitates clot dissolution and restores pulmonary blood flow.
• Cardiac surgery anticoagulation: maintains circuit patency during cardiopulmonary bypass.
• Dialysis anticoagulation: prevents clotting in extracorporeal dialysis circuits.

• Heparin Sodium potentiates antithrombin III, enhancing its inhibitory effect on thrombin (factor IIa) and factor Xa. This acceleration of antithrombin activity blocks key steps in the coagulation cascade, thereby reducing fibrin formation and preventing the extension of existing clots while allowing normal hemostasis to resume once the drug is cleared.

Heparin Sodium may cause a range of adverse reactions, from mild to severe.

Common Side Effects

• Minor bleeding or bruising at injection sites.
• Hematoma formation.
• Localized pain or erythema.
• Hypotension during rapid infusion.
• Nausea or mild gastrointestinal discomfort.

Serious or Rare Side Effects

• Heparin‑induced thrombocytopenia (HIT).
• Major hemorrhage, including intracranial or gastrointestinal bleeding.
• Osteoporosis with prolonged therapy.
• Anaphylactic or severe allergic reactions.
• Adrenal hemorrhage.

Before using Multiparin, clinicians should assess individual bleeding risk and monitor coagulation parameters.

• Renal impairment: adjust monitoring frequency as clearance may be reduced.
• Hepatic dysfunction: observe for altered coagulation profiles.
• Concomitant anticoagulants: increase risk of severe bleeding.
• Recent surgery or trauma: evaluate wound bleeding risk.
• Pregnancy and lactation: weigh maternal benefit against potential fetal risk.
• Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Heparin Sodium interacts with several drug classes that affect hemostasis or platelet function.

Major Interactions (Avoid)

• Other anticoagulants (e.g., warfarin, direct oral anticoagulants).
• Antiplatelet agents (e.g., aspirin, clopidogrel).
• Thrombolytic therapies (e.g., alteplase).
• Non‑steroidal anti‑inflammatory drugs (NSAIDs).
• Spinal or epidural anesthesia: increased risk of spinal hematoma.

Moderate Interactions (Monitor Closely)

• ACE inhibitors and diuretics: may potentiate hypotensive effects.
• Corticosteroids: can increase gastrointestinal bleeding risk.
• Certain antibiotics (e.g., quinolones, macrolides): may affect platelet function.
• Glycoprotein IIb/IIIa inhibitors: additive antiplatelet effect.
• Lipid‑lowering agents (e.g., statins): monitor for rare bleeding events.
