Summary
Mobocertinib carries a labeled risk of QT prolongation and arrhythmia, and volatile anesthetics such as isoflurane can also lengthen the QT interval. Together they may raise the risk of torsades de pointes.
What this interaction means in plain words
Isoflurane and Mobocertinib 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.
Why it happens
Additive prolongation of ventricular repolarization (QTc).
What to do
Check a baseline ECG and correct potassium, magnesium and calcium before anesthesia. Monitor the ECG continuously perioperatively and consider an anesthetic technique with less QT effect if the QTc is prolonged.
What to ask your pharmacist
- Does the benefit of taking both outweigh the risk in my case?
- Do I need any blood test, ECG or other check while on both?
- What early warning signs should I watch for, and what should I do if they appear?
