PCE Dispertab and Sunitinib

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.

Talk to your doctor before using SUNItinib together with erythromycin. Combining these medications can significantly increase the blood levels of SUNItinib. You may be more likely to develop side effects such as diarrhea; constipation; redness, swelling, pain, numbness or tingling in your hands and feet; mouth ulcers or sores; bleeding problems; liver damage; heart problems; high blood pressure; and irregular heartbeat. You may not be able to take erythromycin during treatment with SUNItinib, or you may need a dose adjustment and/or more frequent monitoring by your doctor to safely use both medications. Contact your doctor immediately if you develop fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, light colored stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. You should also seek immediate medical attention if you experience sudden dizziness, lightheadedness, fainting, shortness of breath, difficulty breathing, swelling, chest pain, or fast or pounding heartbeats. 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.

GENERALLY AVOID: Coadministration with potent inhibitors of CYP450 3A4 may increase the plasma concentrations of sunitinib and its pharmacologically active metabolite, both of which are substrates of the isoenzyme. In healthy volunteers, concurrent administration of a single dose of sunitinib with the potent CYP450 3A4 inhibitor, ketoconazole, resulted in a 49% and 51% increase in the combined (i.e., sunitinib plus its primary active metabolite) peak plasma concentration (Cmax) and systemic exposure (AUC) values, respectively, compared to administration of sunitinib alone. Because sunitinib is associated with concentration-dependent prolongation of the QT interval, increased levels may potentiate the risk of ventricular arrhythmias such as torsade de pointes and sudden death.

MANAGEMENT: Alternative agents with no or minimal CYP450 3A4-inhibiting activity are recommended in patients treated with sunitinib. A dosage reduction for sunitinib to a minimum of 37.5 mg daily should be considered if it must be coadministered with potent CYP450 3A4 inhibitors such as itraconazole, ketoconazole, voriconazole, nefazodone, delavirdine, protease inhibitors, and ketolide and certain macrolide antibiotics.
