Edit list (add/remove drugs)

Interactions between your drugs

Moderate

budesonide glofitamab

Applies to: Uceris (budesonide) and glofitamab

MONITOR: Coadministration with glofitamab may increase the plasma concentrations of drugs that are substrates of CYP450 isoenzymes. Initiation of glofitamab treatment causes transient release of cytokines that may suppress CYP450 isoenzymes, although the potential for an interaction has not been studied. According to the manufacturer, the highest drug-drug interaction risk would be from the first dose on day 8 of cycle 1, up to 14 days after the first 30 mg dose on day 1 of cycle 2, as well as during and after cytokine release syndrome.

MANAGEMENT: Caution is advised when glofitamab is administered with drugs that are metabolized by CYP450 isoenzymes, particularly sensitive CYP450 substrates and/or those with a narrow therapeutic range, where minimal changes to concentration may lead to significant adverse reactions, such as carbamazepine, colchicine, cyclosporine, disopyramide, phenytoin, quinidine, theophylline, warfarin, macrolide immunosuppressants, vinca alkaloids, and some narcotic analgesics. Clinical and/or laboratory monitoring are recommended, particularly at the initial phase of treatment with glofitamab as well as during and after cytokine release syndrome, and individual product labeling for the CYP450 substrate(s) should be consulted for specific dosage adjustment recommendations.

Drug and food interactions

Moderate

budesonide food

Applies to: Uceris (budesonide)

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations and systemic effects of orally administered budesonide. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. According to the manufacturer, the systemic exposure of oral budesonide approximately doubles after extensive intake of grapefruit juice.

MANAGEMENT: Patients receiving budesonide should avoid the regular consumption of grapefruits and grapefruit juice to prevent undue increases in plasma budesonide levels and systemic effects.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
