Interactions between your drugs

Moderate

bosutinib pretomanid

Applies to: bosutinib and pretomanid

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with pretomanid may increase the plasma concentrations and the risk of adverse effects of drugs that are substrates of breast cancer resistance protein (BCRP), organic anion-transporting polypeptide (OATP1B3), and/or P-glycoprotein (P-gp). The proposed mechanism, based on in vitro data, is decreased clearance due to pretomanid-mediated inhibition of BCRP, OATP1B3, and/or P-gp. The clinical significance is unknown as data are limited and conflicting.

MANAGEMENT: Until more information is available, the manufacturers of pretomanid recommend that clinicians should be aware of the potential for enhanced pharmacologic effects with drugs that are substrates of BCRP, OATP1B3, and/or Pg-p, particularly those with a narrow therapeutic range, when pretomanid is coadministered. Dosage adjustments as well as clinical and laboratory monitoring of the BCRP, OATP1B3, and/or P-gp substrate drug should be considered whenever pretomanid is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.

Drug and food interactions

Moderate

bosutinib food

Applies to: bosutinib

Bosutinib should be taken with a meal to help with its absorption. Do not consume grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with bosutinib unless directed otherwise by your doctor. Grapefruit juice can significantly increase the blood levels of bosutinib. You may be more likely to experience side effects such as nausea, vomiting, abdominal pain, diarrhea, 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. 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.

Moderate

pretomanid food

Applies to: pretomanid

Food can enhance the levels of pretomanid in your body. Pretomanid should be taken just after eating food. Do not take it on an empty stomach. This will make it easier for your body to absorb the medication. Swallow tablets whole. Do not crush, chew, or break the tablets.
