摘要
Thyroid hormone may increase sensitivity to the effects of tricyclic antidepressants, and combined use has been associated with tachycardia and arrhythmias. Antidepressant response may also be accelerated, but toxicity may emerge more readily, particularly in patients with excess thyroid hormone.
用白話說明這項交互作用的意義
Amitriptyline and Levothyroxine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Amitriptyline belongs to Central Nervous System; Levothyroxine belongs to Endocrine.
為什麼會發生
Thyroid hormone increases beta-adrenergic receptor sensitivity, adding to tricyclic noradrenergic and cardiac effects.
處置方式
Monitor heart rate, rhythm and thyroid function, and avoid over-replacement with levothyroxine. Watch for tricyclic toxicity and ECG changes in patients with cardiac disease.
