Summary
Entrectinib can prolong the QTc interval, and anagrelide adds a similar effect, so the combination increases the risk of serious ventricular arrhythmias. Patients with bradycardia, heart failure or electrolyte disturbances are at greater risk.
What this interaction means in plain words
Anagrelide 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.
Anagrelide belongs to Cardiovascular; Entrectinib belongs to Oncology.
Why it happens
Additive pharmacodynamic prolongation of the QT interval.
What to do
Avoid the combination where an alternative exists. If it cannot be avoided, monitor ECG and electrolytes and adjust or hold entrectinib per labeling for significant QTc prolongation.
