Acute amiodarone pulmonary toxicity with low impregnation dose: case report

Toxicidad pulmonar aguda por amiodarona con dosis baja de impregnación: reporte de caso

Abstract

Amiodarone, considered a potent antiarrhythmic, is known to cause pulmonary toxicity. Chronic interstitial pneumonitis is the most common presentation. However, acute pulmonary toxicity is rare and has a higher case fatality rate. We present a 61-year-old patient with persistent atrial fibrillation who, after a one-month treatment with oral amiodarone at a low dose impregnation of 400 mg/day, develops acute pulmonary toxicity, with radiographic and tomographic resolution after antiarrhythmic suspension and steroid treatment.
