Chỉ định và Liều dùng
Intravenous
Thromboembolism in heparin-induced thrombocytopenia Adult: Initially, 400 mcg/kg by slow IV inj, followed by a maintenance dose of 150 mcg/kg/hr by continuous IV infusion, adjusted according to response, usually for 2-10 days. Monitor response according to the aPTT ratio to achieve a target of 1.5-2.5. Max infusion rate: 210 mcg/kg/hr.

Suy thận
Initially, 200 mcg/kg as slow IV inj, maintenance infusion rate depends on CrCl. For CrCl <15 ml/min, avoid infusion; IV bolus doses of 100 mcg/kg may be used on alternate days in haemodialysis patients or cases of acute renal failure, according to response.

Hướng dẫn pha thuốc
For reconstitution, Sterile Water for Inj USP or 0.9% Sodium Chloride Inj USP may be used. 0.9% Sodium Chloride Inj USP or 5% Dextrose Inj may be used for further dilution. After reconstitution, a clear, colourless solution is usually obtained in a few seconds, but in less than 3 minutes. To prepare the bolus inj, reconstituted solution should be diluted to achieve a final concentration of 5 mg/ml. Reconstituted solution should be used immediately; remains stable for up to 24 hr at room temperature (e.g. during infusion). Preparation should be warmed to room temperature before admin.

Thận trọng
Caution when used in patients with hepatic or renal impairment, patients who are bleeding or at serious risk of bleeding, haemorrhagic blood disorders, recent major bleeding, cerebrovascular disorders, bacterial endocarditis, severe hypertension. Recent major surgery or puncture of large vessels or organ biopsy. Strict monitoring of aPTT is important especially during prolonged therapy. Avoid IM inj as it may cause local haematoma. Pregnancy.

Tác dụng không mong muốn
Bleeding from puncture wounds and sites, haematuria, anaemia. Abnormal LFTs, fever, GI/rectal bleeding.
Potentially Fatal: Severe anaphylactic reactions may occur on re-challenge. |
||||||||
|
Quá liều
Increased risk of bleeding. Treatment is symptomatic.
|
||||||||
|
Tương tác
Concurrent therapy with thrombolytics (e.g. streptokinase) may increase the risk of bleeding complications and prolong aPTT. Parenteral penicillins may increase bleeding time by inhibiting platelet aggregation.

Tác dụng
Description:
Mechanism of Action: Lepirudin is a recombinant hirudin that is a direct thrombin inhibitor. It is used as an anticoagulant in the management of thromboembolic disorders in patients with heparin-induced thrombocytopenia. Pharmacokinetics: Distribution: Mainly distributed to extracellular fluids; initial half-life: Approx 10 minutes. Metabolism: Metabolised renally. Excretion: Approx 45% of an IV dose is detected in the urine and about 35% is excreted unchanged. Terminal half-life: About 1.3 hr; may be increased in severe renal impairment. |
