Sintesi
Phenytoin is an enzyme inducer that reduces isavuconazole exposure, risking loss of antifungal efficacy. Isavuconazole may also modestly raise phenytoin levels.
Cosa significa questa interazione in parole semplici
Isavuconazole and Phenytoin are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Isavuconazole belongs to Anti Fungals; Phenytoin belongs to Central Nervous System.
Perché avviene
Phenytoin induces CYP3A4/5, increasing isavuconazole metabolism.
Cosa fare
Avoid the combination and use a non-inducing anticonvulsant such as levetiracetam, or another antifungal. If it cannot be avoided, monitor isavuconazole and phenytoin concentrations closely.
