OTN Mitoxantrone 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 mitoXANTRONE. This can increase the risk of side effects such as irregular heartbeat, heart failure, and impaired bone marrow function resulting in low numbers of different types of blood cells. You may also be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts. Contact your doctor if you experience potential signs and symptoms of these conditions such as paleness, fatigue, dizziness, fainting, unusual bleeding or bruising, fever, chills, sore throat, body aches, or other flu-like symptoms. You should seek immediate medical attention if you experience sudden, unexplained weight gain; swelling of the hands, ankles, or feet; chest pain; or difficulty breathing, as these may be indications of heart failure. 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 P-glycoprotein (P-gp) may increase the plasma concentrations of mitoxantrone, which is a substrate of the efflux transporter also known as ABCB1 or MDR1. The interaction has been studied with cyclosporine, a potent P-gp inhibitor. In a pharmacokinetic study of 38 children with de novo acute myeloid leukemia, mitoxantrone 6 mg/m2 administered daily in combination with cyclosporine resulted in a 42% decrease in mean mitoxantrone clearance and 12% increase in systemic exposure (AUC) compared to mitoxantrone 10 mg/m2 administered daily without cyclosporine. There were no differences in the rates of stomatitis or infection between the two groups, but an increased incidence of hyperbilirubinemia was observed in the cyclosporine group, which rapidly reversed upon conclusion of treatment. Therefore, it appears a 40% dose reduction of mitoxantrone given with cyclosporine produced statistically similar systemic exposure and toxicity as mitoxantrone given alone.

MANAGEMENT: Caution is advised if mitoxantrone is prescribed in combination with a P-gp inhibitor. Patients should be closely monitored for increased adverse effects including cardiotoxicity and myelosuppression.
