ETHACRYNIC acid is a potent new diuretic which causes sodium and potassium excretion. It is especially useful in patients with refractory edema, cardiac decompensation, hepatic cirrhosis, and renal disease. Side effects such as gastrointestinal symptoms, hypoglycemia, and hyperuricemia, are not unusual. A granulocytosis and neutropenia have been reported. Recently Maher and Schreiner,1 and Schneider and Becker2 have reported transient hearing loss following the administration of ethacrynic acid in humans. A cysteine derivative of ethacrynic acid was withdrawn from clinical use because of high incidence of transient hearing loss. The purpose of this paper is to report a case of hearing loss and describe the pathology following the administration of ethacrynic acid.
