MedicalResearch.com: What is the background for this study?
Response: Early work has suggested a very commonly used antibiotic, clarithromycin, may interfere with the metabolism of the most widely used type of blood thinning medication (called direct oral anticoagulants or DOACs) such that the blood level of the DOAC increases and may place the patient at a higher risk for bleeding. In our study we looked at patients of advanced age (>66 years old) who were given clarithromycin while on a DOAC in Ontario, Canada. We compared patients on clairthromycin-DOAC to patients given a very similar antibiotic, azithromycin, that does not interfere with the metabolism of DOAC. (more…)
