Summary
Both drugs prolong the QT interval, so combining them increases the risk of torsades de pointes and sudden cardiac death. Panobinostat labeling advises against use with QT-prolonging drugs.
What this interaction means in plain words
Fluconazole and Panobinostat 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.
Fluconazole belongs to Anti Fungals; Panobinostat belongs to Oncology.
Why it happens
Additive QT prolongation; fluconazole's CYP3A4 inhibition may also raise panobinostat levels.
What to do
Avoid the combination and use a non-QT-prolonging antifungal. If unavoidable, obtain baseline and serial ECGs and keep potassium and magnesium in normal range.
