خلاصه

Phenytoin is an enzyme inducer that reduces isavuconazole exposure, risking loss of antifungal efficacy. Isavuconazole may also modestly raise phenytoin levels.

معنای این تداخل به زبان ساده

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.

سطح شواهد: High

چرا رخ می‌دهد

Phenytoin induces CYP3A4/5, increasing isavuconazole metabolism.

اقدام لازم

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.
