Summary
Both drugs can prolong the QT interval, and encorafenib does so in a dose-related way. Used together they may add to the risk of torsades de pointes, especially with electrolyte disturbance or bradycardia.
What this interaction means in plain words
Encorafenib and Sotalol 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.
Encorafenib belongs to Oncology; Sotalol belongs to Cardiovascular.
Why it happens
Additive pharmacodynamic QT prolongation through cardiac repolarization (potassium channel) effects.
What to do
Avoid the combination where an alternative exists; if unavoidable, obtain baseline and follow-up ECGs and correct potassium and magnesium. Reduce or hold encorafenib if QTc becomes markedly prolonged.
