Background

Dabigatran is an oral anticoagulant that acts via direct inhibition of thrombin in the blood. It is used for prevention of stroke, systemic embolism and reduction of vascular mortality in patients with non-valvular atrial fibrillation, the prevention of venous thromboembolic events in patients who have undergone major orthopaedic surgery and the treatment and prevention of deep vein thrombosis and/or pulmonary embolism.

Dabigatran has been listed in Section B (community) and in Part II of Section H (DHB hospitals) of the Pharmaceutical Schedule since 1 July 2011. Dabigatran is now used regularly by more than 20,000 people in New Zealand.  

Idarucizumab is a specific reversal agent for dabigatran that was approved by Medsafe for use in New Zealand in December 2015. It is indicated in patients treated with dabigatran when rapid reversal of the anticoagulant effects of dabigatran is required for emergency surgery/urgent procedures, or situations of life-threatening or uncontrolled bleeding.

Previously, a specific dabigatran reversal agent has not been available. Measures to control bleeding relied largely on supportive measures and treatments that did not have their efficacy established in clinical trials. In response to the lack of alternatives, PHARMAC produced guidelines on the management of bleeding and perioperative management with expert clinical advice from the Heamatology Subcommittee of PTAC.

PHARMAC’s Pharmacology and Therapeutics Advisory Committee (PTAC) considered idarucizumab at its meeting in November 2015. The Committee recommended that idarucizumab be listed for the specific reversal of the anticoagulant effects of dabigatran when required in situations of life-threatening or uncontrolled bleeding, or for emergency surgery or urgent procedures, with a medium priority. Further details of PTAC’s advice are in the relevant PTAC meeting minutes; these are available via the application tracker on our website here:
