Chapter 3: An Introduction to New Oral Anticoagulants
The following sections are included:
New oral anticoagulants (NOACs) are growing in popularity as an alternative to warfarin.
No monitoring of coagulation is required.
Fixed once or twice daily dosing.
Bridging with low molecular weight heparin (LMWH) is not required when commencing treatment with NOACs due to their quick onset of action.
Dose adjustments are required in renal failure.
NOACs have a favourable safety profile in comparison to warfarin, but care is required for the elderly who may be at risk of a gastrointestinal bleed.
NOACs can be used in VTE prevention for elective orthopaedic surgery, VTE treatment and prevention of arterial thromboembolism in patients with atrial fibrillation.
NOACs are not yet recommended for anticoagulation control in patients with prosthetic heart valve and acute coronary syndrome.
