What this interaction means in plain words

Ezogabine and Voriconazole can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Ezogabine belongs to Central Nervous System; Voriconazole belongs to Anti Fungals.

Evidence level: Low

Why it happens

Additive pharmacodynamic QT interval prolongation.

What to do
