Arrow Only Amiodarone

Not all Potassium channel blockers cause thyroid disorders. It's only Amiodarone.
Sotalol, Bretylium, and Ibutilide (other K channel blockers) do not cause thyroid dysfunction.

To learn how Amiodarone cause hypo or hyperthyroidism I recommend you read our previous thread here
Amiodarone Hypo or Hyper thyroidism?
