摘要
Primaquine can prolong the QT interval, and amiodarone strongly prolongs repolarization, so combined use raises the risk of torsades de pointes. Amiodarone's long half-life means the risk persists after it is stopped.
用白話說明這項交互作用的意義
Amiodarone and Primaquine 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.

為什麼會發生
