Interactions between your drugs
rosuvastatin olaparib
Applies to: rosuvastatin and olaparib
MONITOR: Based on in vitro inhibition data, coadministration with olaparib may increase the plasma concentrations of drugs that are substrates of CYP450 3A4 (e.g., cisapride, ergot alkaloids, fentanyl, lovastatin, oral midazolam, pimozide, quetiapine, simvastatin, triazolam, vinca alkaloids), P-gp (e.g., colchicine, dabigatran, digoxin), breast cancer resistance protein (BCRP) (e.g., rosuvastatin), OATP1B1 (e.g., eluxadoline, glyburide, repaglinide, statins, valsartan), or organic cation transporter 1 or 2 (OCT1, OCT2) (e.g., metformin). The proposed mechanism is decreased clearance due to inhibition of the corresponding metabolizing enzyme and/or efflux/uptake transporter by olaparib.
MANAGEMENT: Caution is advised if olaparib must be used concomitantly with drugs that are substrates of the affected enzymes or transporters, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever olaparib is added to or withdrawn from therapy.

Drug and food interactions
olaparib food
Applies to: olaparib
GENERALLY AVOID: Grapefruit juice may significantly increase the plasma concentrations of olaparib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. In a drug interaction study with 57 patients, olaparib systemic exposure (AUC) was increased approximately 2.7-fold by the potent CYP450 3A4 inhibitor itraconazole. Simulations using physiologically-based pharmacokinetic (PBPK) models suggest that a moderate inhibitor (fluconazole) may increase the AUC of olaparib by 2-fold. The interaction has not been studied with grapefruit juice. 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. Increased exposure to olaparib may increase the risk of adverse effects such as hematologic toxicity, nausea, vomiting, diarrhea, anorexia, dyspepsia, and abdominal pain or discomfort.
MANAGEMENT: Patients treated with olaparib should avoid consumption of grapefruit, grapefruit juice, starfruit (carambola), and Seville oranges.
