Purpose: The aim of this review is to discuss possible interactions that may occur between warfarin and fruit products. Methods: A literature search was conducted using the search terms: “warfarin (Coumadin®) and fruit interactions, warfarin and fruit, warfarin and fruit juice, case reports and clinical trials”.
Recommended dosing conversions for anticoagulants such as warfarin, heparin, and dabigatran.
For patients with established cardiovascular disease and atrial fibrillation, warfarin treatment correlates with a lower risk of a composite of death, myocardial infarction (MI), and ischemic stroke, with no increased risk of bleeding.
Study patients were randomized to Pradaxa 150mg twice daily or warfarin (target INR 2-3) and remained on this treatment for the trial duration.
Drugs in the Pipeline
Boehringer Ingelheim announced results from the RE-COVER II study evaluating dabigatran compared to warfarin in patients diagnosed with acute deep vein thrombosis (DVT) and/or pulmonary embolism (PE).
For warfarin-treated patients, carbamazepine co-treatment is associated with subtherapeutic anticoagulative effect and increased warfarin dose requirements, according to a study published online in the Journal of Thrombosis and Haemostasis.
In a group of septuagenarian patients with atrial fibrillation, followed for up to six years, warfarin use is associated with a significant reduction in all-cause mortality.
The researchers searched the U.S. Medicare database for NVAF patients 65 years of age and older who were newly prescribed one of the following medications: apixaban, dabigatran, rivaroxaban, or warfarin.
Treating acute ischemic stroke patients who are warfarin users with tissue plasminogen activator (tPA) does not increase the risk of intracranial hemorrhage (ICH).
While the use of NSAIDs was low in the ARISTOTLE trial, NSAID users had a higher risk for bleeding than non-users.
