摘要
Etrasimod is cleared by CYP2C8, CYP2C9 and CYP3A4. Amiodarone inhibits CYP2C9 and CYP3A4 and may raise etrasimod exposure. Both drugs can slow heart rate and conduction, so bradyarrhythmia risk is a concern.
用白話說明這項交互作用的意義
Amiodarone and Etrasimod can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Amiodarone belongs to Cardiovascular; Etrasimod belongs to Gastrointestinal Tract.
為什麼會發生
Inhibition of CYP2C9 and CYP3A4 by amiodarone raises etrasimod levels, with additive bradycardic effects.
處置方式
Avoid the combination; labeling advises against etrasimod with moderate-to-strong dual CYP2C9/CYP3A4 inhibitors. If unavoidable, monitor heart rate and ECG.
