Amiodarone-induced pulmonary toxicity.

Amiodarone hydrochloride, an investigational drug used to suppress ventricular arrhythmias, may cause pulmonary toxicity with associated radiographic abnormalities. Two patients are presented who illustrate the variability of these abnormalities. One of these patients died of respiratory failure while the other recovered after amiodarone was stopped and corticosteroid therapy was started.
