Cotellic and Kaletra

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.

Ritonavir may significantly increase the blood levels of cobimetinib. 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. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. 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 significantly increase the plasma concentrations of cobimetinib, which is primarily metabolized by the isoenzyme. In 15 healthy volunteers given a single 10 mg dose of cobimetinib with the potent CYP450 3A4 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. The risk and/or severity of adverse effects such as diarrhea, nausea, vomiting, stomatitis, hemorrhage, cardiomyopathy, rash, photosensitivity, retinopathy, retinal vein occlusion, liver enzyme abnormalities, and rhabdomyolysis may be increased.

MANAGEMENT: Concomitant use of cobimetinib with potent CYP450 3A4 inhibitors should generally be avoided.
