Moderate

prednisoLONE isavuconazonium

Applies to: Predicort-50 (prednisolone) and isavuconazonium

MONITOR: Coadministration with isavuconazonium sulfate (prodrug of isavuconazole) may increase the plasma concentrations of drugs that are substrates of CYP450 3A4 and/or P-glycoprotein (P-gp). The mechanism is decreased clearance due to inhibition of CYP450 3A4 activity and/or P-gp-mediated efflux of these drugs by isavuconazole. In pharmacokinetic studies, isavuconazole increased the systemic exposure (AUC) of sensitive CYP450 3A4 substrates midazolam, sirolimus, and tacrolimus by approximately 2-fold, thus it can be considered a moderate inhibitor of the isoenzyme.

MANAGEMENT: Caution is advised when isavuconazonium sulfate is used concomitantly with drugs that are substrates of the CYP450 3A4 isoenzyme or the P-gp transport protein, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever isavuconazonium sulfate is added to or withdrawn from therapy.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
