Interactions between your drugs

Moderate

alpelisib leniolisib

Applies to: Vijoice (alpelisib) and leniolisib

GENERALLY AVOID: Coadministration of inhibitors of the breast cancer resistance protein (BCRP) transporter with alpelisib may increase the plasma concentrations and risk of adverse effects of alpelisib, which is a substrate of this efflux transporter. Alpelisib has been identified as a substrate of BCRP in in vitro studies. However, clinical data are not available.

MANAGEMENT: If coadministration with BCRP inhibitors is required, patients should be closely monitored for alpelisib-related adverse reactions, including hyperglycemia, diarrhea, rash, acute kidney injury, abdominal pain, and anemia. Some authorities recommend coadministration of alpelisib with BCRP inhibitors be avoided whenever possible (US).

Drug and food interactions

Moderate

alpelisib food

Applies to: Vijoice (alpelisib)

ADJUST DOSING INTERVAL: Food significantly enhances the oral absorption and bioavailability of alpelisib. When administered with a high-fat high-calorie meal (985 calories with 58.1 g of fat) or a low-fat low-calorie meal (334 calories with 8.7 g of fat) the AUC and Cmax of a single dose of alpelisib was increased by 73% and 84% and 77% and 145%, respectively. There were no clinically significant differences in alpelisib AUC between the two types of meals. In addition, food appears to have a more pronounced effect on the solubility of alpelisib than gastric pH. When coadministered with a single 300 mg dose of alpelisib, ranitidine decreased the absorption and overall exposure of alpelisib. Following administration of ranitidine with a low-fat low-calorie meal, the mean AUC and Cmax of alpelisib was decreased by 21% and 36%, respectively. Administration of ranitidine under fasting conditions reduced the mean AUC and Cmax of alpelisib by 30% and 51%, respectively.

MANAGEMENT: To ensure maximal oral absorption, alpelisib should be administered with a meal.

leniolisib food

Applies to: leniolisib

MONITOR: Coadministration with inhibitors of CYP450 3A4 including grapefruit or grapefruit juice may increase the plasma concentrations of leniolisib, which undergoes extensive CYP450 3A4-mediated first-pass metabolism in the gut wall and liver. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Pharmacokinetic interactions involving grapefruit juice are also subject to a high degree of interpatient variability, thus the extent to which a given patient may be affected is difficult to predict.

MANAGEMENT: Patients who regularly consume grapefruit or grapefruit juice should be monitored for adverse effects and altered plasma concentrations of leniolisib. Some authorities recommend to avoid grapefruit products during leniolisib treatment (UK).

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.

Duplication

Pi3k inhibitors

Therapeutic duplication

The recommended maximum number of medicines in the 'PI3K inhibitors' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'PI3K inhibitors' category:

  • leniolisib
  • Vijoice (alpelisib)

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.

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.
