Reviparin sodium clivarine: a review of its therapeutic use.

摘要

Reviparin sodium (clivarine) is a second generation LMWH, developed with the aim of maximising the antithrombotic action while minimising the risk of haemorrhage. Clivarine has been extensively studied in acute coronary syndrome. Various clinical studies in unstable angina and acute coronary syndrome have proved that clivarine in a dosage of 3436anti-Xa units twice daily is an effective antithrombotic agent. Clivarine has been shown to be as effective as unfractionated heparin (UFH) in thromboprophylaxis and it has less incidence of local haematoma at injection site. At a daily dose of 1432 IU anti-Xa it was found to be as effective as UFH in preventing deep vein thrombosis (DVT) in moderate risk surgery (general and abdominal) and reducing to a significant extent DVT in patients with brace immobilisation of the legs. At a daily dose of 3436 IU anti-Xa reviparin was as effective as UFH or enoxaparin in preventing DVT in high risk orthopaedic surgery and as effective as UFH in prevention of DVT and/or pulmonary embolism (PE) and/or mortality in high risk orthopaedic surgery. In patients with acute venous thrombo-embolism (VTE), reviparin was more effective than UFH in thrombus reduction and at least as effective as UFH in the prevention of clinical recurrence of DVT and/or PE. The use of reviparin is associated with a similar or lower incidence of bleeding complications than UFH. The benefits of reviparin sodium have been demonstrated in a number of clinical trials.
