Amiodarone is regarded as a highly effective anti-arrhythmic agent, but its use may lead to alterations in thyroid gland function and/or thyroid hormone metabolism, partly because of its rich iodine content. Patients treated with amiodarone may manifest an altered thyroid hormone profile without thyroid dysfunction, or they may present clinically significant amiodarone-induced hypothyroidism or amiodarone-induced thyrotoxicosis. Нypothyroidism prevails in areas with high dietary iodine intake, and it is readily managed by discontinuation of amiodarone or thyroid hormone replacement. Amiodarone-induced thyrotoxicosis occurs more frequently in areas with low iodine intake; it may arise from iodine-induced excessive thyroid hormone synthesis (type I) or destructive thyroiditis with release of preformed hormones (type II). Type I should be treated with thionamides alone or in combination with potassium perchlorate, whereas type II benefits from treatment with glucocorticoids. |
