Isavuconazonium Sulfate Capsules and PCE Dispertab

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Erythromycin may increase the blood levels of isavuconazole, the active component of isavuconazonium. This can increase the risk and/or severity of side effects such as nausea, vomiting, diarrhea, and liver problems. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Coadministration with inhibitors of CYP450 3A4 may increase the plasma concentrations of isavuconazole, which is primarily metabolized by CYP450 3A4 and 3A5 and subsequently by uridine diphosphate glucuronosyltransferases (UGT). When a single dose of isavuconazonium sulfate (equivalent to 200 mg of isavuconazole) was administered to healthy volunteers following multiple dosing of the potent CYP450 3A4 inhibitor ketoconazole (200 mg twice daily for 24 days), isavuconazole peak plasma concentration (Cmax) increased by 9% and systemic exposure (AUC) increased by 422%. Lopinavir-ritonavir (400 mg-100 mg twice daily) increased the Cmax and AUC of isavuconazole by 74% and 96%, respectively.

MANAGEMENT: Caution is advised when isavuconazonium sulfate is prescribed with CYP450 3A4 inhibitors. Patients should be monitored for adverse effects such as nausea, vomiting, diarrhea, peripheral edema, hypokalemia, hypomagnesemia, and hepatotoxicity. In addition, many CYP450 3A4 inhibitors are also substrates of the isoenzyme, thus pharmacologic response to these agents should also be monitored, as isavuconazole itself is reportedly a moderate CYP450 3A4 inhibitor.
