Cardioquin and Cotellic

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.

QuiNIDine may increase the blood levels of cobimetinib. In some cases, this may increase the risk and/or severity of side effects such as nausea, vomiting, diarrhea, mouth sores, bleeding, heart problems (e.G., heart failure), rash, photosensitivity (i.E., increased sensitivity to sunlight), eye problems, liver injury, and muscle damage. Contact your doctor if your condition changes or you experience increased side effects. 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 and/or P-glycoprotein (P-gp) may increase the plasma concentrations of cobimetinib, which is a substrate of both the isoenzyme and the efflux transporter. In 15 healthy volunteers given a single 10 mg dose of cobimetinib with the potent CYP450 3A4 and P-gp inhibitor itraconazole (200 mg once daily for 14 days), mean cobimetinib peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 3.2- and 6.7-fold, respectively, compared to cobimetinib administered alone. Simulations using physiologically-based pharmacokinetic (PBPK) models suggest that steady-state concentrations of cobimetinib given at a reduced dose of 20 mg with short-term (less than 14 days) use of a moderate CYP450 3A4 inhibitor would be similar to steady-state concentrations observed following a 60 mg dose given alone.

MANAGEMENT: Caution is advised when cobimetinib is prescribed with CYP450 3A4 and/or P-gp inhibitors. Patients should be monitored for adverse effects such as diarrhea, nausea, vomiting, stomatitis, hemorrhage, cardiomyopathy, rash, photosensitivity, retinopathy, retinal vein occlusion, liver enzyme abnormalities and rhabdomyolysis, and the cobimetinib dosage adjusted accordingly or treatment discontinued as necessary.
