Darunavir Tablets and Farydak

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.

Darunavir may increase the blood levels of panobinostat. You may be more likely to experience side effects such as nausea; vomiting; diarrhea; loss of appetite; fatigue; swelling in the arms or legs; heart problems (e.G., chest pain, heart failure, irregular heartbeat); liver problems; 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 panobinostat, which is partially metabolized by the isoenzyme. In 14 patients with advanced or metastatic solid tumors, administration of a single 20 mg dose of panobinostat on day 4 of multiple once daily dosing of 400 mg ketoconazole, a potent CYP450 3A4 inhibitor, resulted in 1.6- and 1.8-fold increases in mean panobinostat peak plasma concentration (Cmax) and systemic exposure (AUC), respectively, compared to administration of panobinostat alone. Ketoconazole caused a greater than 2-fold increase in Cmax and AUC of panobinostat in a limited number of patients. QTc prolongation >30 ms over baseline occurred in 5 patients during concomitant administration, compared to 4 patients during panobinostat alone and 3 patients during ketoconazole alone. Other ECG abnormalities occurred in 6 patients during concomitant administration and 3 patients during either panobinostat or ketoconazole alone. No significant alteration in time to maximum concentration (Tmax) or half-life of panobinostat was observed. The interaction has not been studied with other, less potent inhibitors.

MANAGEMENT: Caution is advised when panobinostat is prescribed with CYP450 3A4 inhibitors. Patients should be monitored for adverse effects such as nausea, vomiting, diarrhea, anorexia, peripheral edema, cardiotoxicity, ECG abnormalities, electrolyte disturbances, bleeding complications, hepatotoxicity and myelosuppression, and the dosage of panobinostat adjusted as necessary in accordance with the product labeling.
