Kaletra and Ponatinib

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 increase the blood levels of PONATinib. You may be more likely to experience side effects such as nausea; vomiting; abdominal pain; constipation; skin rash; mouth sores; high blood pressure; blood clots; fluid retention; heart failure; liver damage; 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 already be aware of the interaction, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. You should contact your doctor immediately if you develop sudden dizziness, fainting, chest pain, palpitation, shortness of breath, weakness on one side of the body, speech impairment, leg pain or swelling, or any signs of infection, as these may be symptoms of potentially serious side effects. You should also seek prompt medical attention if you have signs and symptoms of liver damage such as 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 yellowing of the skin or eyes. 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.

ADJUST DOSE: Coadministration with potent inhibitors of CYP450 3A4 may increase the plasma concentrations of ponatinib, which is a substrate of the isoenzyme. In 22 healthy volunteers, administration of a single 15 mg oral dose of ponatinib in combination with the potent CYP450 3A4 inhibitor ketoconazole (400 mg daily) increased ponatinib peak plasma concentration (Cmax) and systemic exposure (AUC) by 47% and 78%, respectively, compared to administration of ponatinib alone.

MANAGEMENT: Caution is recommended if concomitant use is required, and the recommended starting dosage of ponatinib should be reduced to 30 mg once daily. Patients may be at increased risk for adverse effects such as thromboembolism, ischemia, congestive heart failure, hypertension, hepatotoxicity, pancreatitis, myelosuppression, hemorrhage, and fluid retention.
