Ten-year trends in prescribing of antiarrhythmic drugs in Australian primary care patients with atrial fibrillation

Despite changes in antiarrhythmic drug (AAD) choice in patients with atrial fibrillation (AF), trends in AAD prescribing remain not investigated. We aimed to examine these changes using a nationwide Australian general practice data from 2009 to 2018. Over the 10 years, AAD prescribing in patients with AF decreased, which was mainly due to a reduction in the use of amiodarone, sotalol and digoxin. In contrast, the use of beta-blockers and flecainide increased.
