Ibrance 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 palbociclib. You may be more likely to experience side effects such as nausea; vomiting; diarrhea; loss of appetite; mouth sores; hair loss; weakness; pain, numbness, or tingling in the hands and feet; and impaired bone marrow function resulting in low numbers of different types of blood cells, which can increase the risk of anemia, bleeding problems, and infections. 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 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 palbociclib, which is a substrate of the isoenzyme. In 12 healthy study subjects, administration of a single 125 mg dose of palbociclib with multiple 200 mg daily doses of itraconazole, a potent CYP450 3A4 inhibitor, resulted in 34% and 87% increases in palbociclib peak plasma concentration (Cmax) and systemic exposure (AUC), respectively, compared to palbociclib administered alone. No data are available for use with other, less potent inhibitors.

MANAGEMENT: Caution is advised when palbociclib is used with CYP450 3A4 inhibitors. Dosage adjustment for palbociclib is not generally considered necessary for suspected interactions with mild to moderate inhibitors. However, patients should be monitored for increased adverse effects such as infections, neutropenia, leucopenia, anemia, thrombocytopenia, anorexia, nausea, vomiting, diarrhea, stomatitis, alopecia, asthenia, peripheral neuropathy, and epistaxis.
