[Antiarrhythmic effect and side effects of amiodarone]
Wiener Klinische Wochenschrift
|September 28, 1984
Summary
Amiodarone effectively treats refractory arrhythmias, with 41% of patients showing no detectable arrhythmias and 37% experiencing significant improvement. However, side effects like keratopathy and phototoxicity are common.
Area of Science:
- Cardiology
- Pharmacology
Context:
- Amiodarone (AM) is a potent antiarrhythmic drug with significant side effects.
- Patients studied had refractory arrhythmias, including ventricular tachycardia and WPW-tachycardia, often after failing multiple other treatments.
Purpose:
- To evaluate the efficacy and safety of amiodarone in patients with refractory arrhythmias.
- To assess clinical outcomes and side effects of amiodarone therapy.
Summary:
- Amiodarone therapy rendered initial arrhythmias undetectable in 41% of patients and significantly improved them in 37%.
- Common side effects included reversible keratopathy (100%) and increased phototoxicity (31%).
- Thyroid function abnormalities (ETR, T4 elevation) occurred in 27%, with rare cases of hyper- or hypothyroidism.
Impact:
- Amiodarone is highly effective for refractory arrhythmias, but its use necessitates careful monitoring due to potential side effects.
- The study highlights the need for judicious use of amiodarone in patients with severe, treatment-resistant arrhythmias.
