Updates in antiarrhythmic therapy for atrial fibrillation in geriatric patients

Abstract

Objective: To provide a review of the current evidence for the use of antiarrhythmic therapy in the geriatric population.

Data sources: A PubMed search of articles in the English language published from 1990 through August 2014 was performed using a combination of the following words: amiodarone, antiarrhythmic, atrial fibrillation, dofetilide, dronedarone, elderly, flecainide, geriatric, propafenone, sotalol.

Study selection/data extraction: Relevant original studies, review articles, and guidelines were assessed for use of antiarrhythmic therapy to manage atrial fibrillation (A fib) in the elderly. References from the above literature were also evaluated and included based on their relevance.

Data synthesis: The incidence of A fib increases as the population ages, which creates an increased need for clinicians to understand the place of antiarrhythmic therapy in management of A fib. This article provides a review of the current literature regarding this high-risk class of medications in the elderly population, with a focus on monitoring parameters and clinical considerations in the geriatric population.

Conclusion: Elderly patients are more susceptible to the adverse effects of antiarrhythmic medications as a result of multiple factors, including decreased clearance and metabolism of medications as well as interactions caused by comorbid conditions and medications. Pharmacists can play a key role in a multidisciplinary team to monitor and educate patients on their antiarrhythmic therapy.
