Still, says Peterson, "most people won't have issues unless they eat large quantities of grapefruit, drink more than one liter per day of grapefruit juice, or consistently eat or drink grapefruit.

The first published report on grapefruit drug interactions was in 1991 in the Lancet entitled "Interactions of Citrus Juices with Felodipine and Nifedipine", and was the first reported food-drug interaction clinically. The effects of grapefruit last ...
Likewise it is a CYP3A4, CYP2D6 and CYP2C9 inhibitor and hence concurrent treatment with substrates of any of these enzymes may increase plasma concentrations of said drugs. [26] Since imatinib is mainly metabolised via the liver enzyme CYP3A4, substances influencing the activity of this enzyme change the plasma concentration of the drug.
Thomas Packard was diagnosed with Stage 4 colon cancer after rectal bleeding, using the bathroom a dozen times a day. He had six months to live. Doctors used HAI to treat him.
Nilotinib is used to treat Philadelphia chromosome (Ph+)-positive chronic myelogenous leukaemia.

Doctors created a treatment plan that included 40 weeks of chemotherapy with six weeks of radiation after the first three months of chemotherapy. “By fall they said that everything should be ...
Additionally, the combination of lorlatinib with rifampicin showed liver toxicity in studies. Inhibitors of these enzymes such as ketoconazole or grapefruit juice increase lorlatinib plasma concentrations, leading to higher toxicity. Lorlatinib is also a (moderate) CYP3A4/5 inducer, so that drugs that are metabolized by these enzymes are broken ...
