Abstract:
Amiodarone is a class III antiarrhythmic drug with a structure comparable to thyroid hormone and 37% iodine content by weight. In addition to direct drug cytotoxicity on thyroid cells, amiodarone deiodination in the body releases an excessive amount of iodine, which can impair thyroid function and cause hypothyroidism or thyrotoxicosis, including thyroid storm in susceptible individuals. In this report, we discuss the case of a 52-year-old woman who experienced a thyroid storm after being treated with amiodarone, eventually leading to her death.
