Amiodarone is a class III anti-arrhythmic for tachyarrhythmias
Although most patients remain euthyroid on amiodarone, 4-18% develop thyroid disease months to years after exposure.
Amiodarone-induced thyroid disease occurs because amiodarone is structurally similar to triiodothyronine and thyroxine and each 200mg tablet contains 75 mg of iodine.
Two types of amiodarone-induced thyroid disease:
Amiodarone-induced hypothyroidism (AIH)
Amiodarone-induced thyrotoxicosis (AIT)
