Implication

Reserve amiodarone for AF with LV dysfunction, acute ventricular arrhythmias, or ICD adjunct; confirms targeted efficacy while underscoring toxicity monitoring needs.

Key Points

To evaluate and synthesize clinical evidence regarding the optimal indications, efficacy, and adverse effect profile of amiodarone across various cardiac arrhythmias.
Systematic search of MEDLINE (1970–2007) to identify peer-reviewed clinical trials, randomized controlled trials, meta-analyses, and official clinical guidelines.
Identified and reviewed 92 English-language, human-participant studies evaluating amiodarone in cardiac conditions such as ventricular arrhythmias, atrial fibrillation, and cardiac surgery.
Amiodarone shows clear clinical utility in acute sustained ventricular tachyarrhythmias, atrial fibrillation with left ventricular dysfunction, perioperative cardiac surgery prophylaxis, and reducing implantable cardioverter-defibrillator shocks.
Minor and frequent adverse effects include corneal microdeposits (>90%), photosensitivity (25%–75%), elevated liver enzymes (15%–30%), and blue-gray skin discoloration (4%–9%).
Serious toxicities include pulmonary toxicity (1%–17%), hypothyroidism (6%), hyperthyroidism (0.9%–2%), optic neuropathy/neuritis (≤1%–2%), peripheral neuropathy (0.3% annually), and hepatitis or cirrhosis (<3% [0.6% annually]).

Structured PICO

What is the optimal clinical use and adverse effect profile of amiodarone for various arrhythmias?

Population

92 studies evaluating patients with various arrhythmias including atrial fibrillation, atrial flutter, ventricular arrhythmia, ventricular fibrillation, electrical storm, and those undergoing cardiac surgery or with implantable cardioverter-defibrillators.

Intervention

Amiodarone

Outcome

Optimal use and adverse effects of amiodarone

Amiodarone should be reserved for patients likely to derive the most benefit, such as those with AF and LV dysfunction, acute ventricular arrhythmias, or ICDs, due to its extensive adverse effect profile.
