Interaction Details
Dabrafenib is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, cranberry might increase the levels and adverse effects of CYP3A4 substrates.
A case of upper back pain, rhabdomyolysis, and abnormal liver function has been reported for a patient taking atorvastatin, a CYP3A4 substrate, in combination with cranberry juice 16 ounces daily for 2 weeks. Creatinine kinase and liver enzymes normalized within 2 weeks of stopping cranberry juice. Also, animal research suggests that cranberry juice, administered intraduodenally 30 minutes prior to nifedipine, a CYP3A4 substrate, inhibits nifedipine metabolism and increases the area under the concentration-time curve by 1.6-fold compared to control.

Cranberry Overview
Cranberries are a type of small, tart berry native to North America. They are a rich source of antioxidants, which are substances that help to protect cells from damage caused by harmful substances called free radicals. They are also a good source of vitamin C, fiber, and other nutrients.
Cranberry dietary supplements contain concentrated cranberry extract or powdered cranberry fruit. They are often used to prevent or treat urinary tract infections (UTIs), as cranberries are thought to have certain compounds that may help to prevent bacteria from attaching to the urinary tract.
Dabrafenib Overview
-
Dabrafenib is used alone or in combination with trametinib (Mekinist) to treat a certain types of melanoma (a type of skin cancer) that cannot be treated with surgery or that has spread to other parts of the body. It is also used along with trametinib to treat and prevent the return of a certain type of melanoma after surgery to remove it and any affected lymph nodes. Dabrafenib is also used in combination with trametinib to treat a certain type of non-small cell lung cancer (NSCLC) that has spread to nearby tissues or to other parts of the body. It is also used to treat a certain type of thyroid cancer that has spread to nearby tissues or to other parts of the body that has not responded to previous treatment(s). Dabrafenib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.
