概要
Both drugs can prolong the QTc interval, so combined use increases the risk of ventricular arrhythmias including torsades de pointes. The risk is greater with electrolyte disturbances, bradycardia or heart disease.
この相互作用をわかりやすく説明すると
Amitriptyline and Entrectinib 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.
Amitriptyline belongs to Central Nervous System; Entrectinib belongs to Oncology.
なぜ起こるのか
Additive blockade of cardiac repolarizing potassium channels leading to QTc prolongation.
対処法
Obtain a baseline ECG and monitor it periodically, keeping potassium and magnesium normal. Consider an alternative antidepressant if QTc lengthens substantially.
