Amiodarone: A Newly Discovered Association with Bilateral Vestibulopathy

Gürkov, Robert (2018): Amiodarone: A Newly Discovered Association with Bilateral Vestibulopathy. In: Frontiers in Neurology, Bd. 9, 119

Abstract

Background: Bilateral vestibulopathy (BVP) is a debilitating disorder characterized by the hypofunction of both vestibular end organs or nerves. The most frequent identifiable causes of BVP are ototoxic drug effects, infectious and autoimmune disorders. However, the majority of cases remain idiopathic. Very recently, the first discovery of a clinical case of Amiodarone-associated BVP has been reported. Methods: An overview of the literature concerning the relation between amiodarone toxicity and BVP is presented and discussed. Results: Older reports on amiodarone-induced symptoms of vertigo and gait instability lack a description of vestibular function test results. Recent evidence from retrospective studies including vestibular function testing in patients taking amiodarone have identified the drug as the hitherto unsuspected potential cause of a relatively large proportion of cases with "idiopathic" BVP. Conclusion: Patients who receive amiodarone should be monitored with vestibular function testing in order to recognize potential adverse effects on the vestibular system and allow for an informed decision on possible drug reduction or withdrawal.
