Sažetak
Drug-drug interactions (DDIs) are one potential cause of adverse drug events. Very little has been done to study the relationship between potential DDIs in patients (p) with atrial fibrillation (AF) on direct oral anticoagulants (DOACs). Many anticoagulants are eliminated by the kidneys, so they can accumulate if their dose is not adapted to the kidney function. DDI is one particular type of drug error that can result in adverse drug events (ADEs) in exposed patients and was the aim of this study. A total of 50 patients with AF on DOACs (25 patients on dabigatran and 25 on rivaroxaban) with normal, mildly or moderately decreased (estimated GFR > 30 mlmin-11.73m2) renal function were included (age 69±7 years, 26M/24F, body mass index (BMI) 35.4±5.1 kg/m2, duration of hypertension 11±5 years, duration of AF 5±2 years, eGFR 58±23 mlmin-11.73m2 (was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD- EPI) formula). The 12-month administration of DOACs caused a nonsignificant decrease of eGFR (declined from 58±23 mlmin-11.73m2 to 56±17 mlmin-11.73m2 (p=0.01). All patients have the right dose of DOACs according to eGFR. Patients with AF and DOACs on more than 3 different drugs (20%) such as statins, verapamil and amiodarone were more prone to AE. DDIs are one of the most important problems in every day practice. Coadministration of statins with dabigatran worsens clinical outcomes and a similar interaction might be seen with verapamil and amiodarone. Patients need to be on the right drug/right dose given the kidney function they have, with special care on DDIs.
