- lansoprazole/naproxen
Interactions between your drugs
naproxen PONATinib
Applies to: lansoprazole / naproxen and Iclusig (ponatinib)
MONITOR CLOSELY: Coadministration of ponatinib and drugs that interfere with platelet function or coagulation may potentiate the risk of bleeding complications. Treatment with ponatinib is associated with severe, sometimes fatal hemorrhage including cerebral and gastrointestinal hemorrhage. In clinical trials, hemorrhagic events occurred in 24% of patients treated with ponatinib, and serious events occurred in 5% of patients. The incidence of serious bleeding events was higher in patients with accelerated phase or blast phase chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL). Most hemorrhagic events occurred in patients with grade 4 thrombocytopenia.
MANAGEMENT: Concomitant use of other medications that interfere with platelet function or coagulation should be considered cautiously in patients treated with ponatinib. Close clinical and laboratory observation for bleeding complications is recommended during therapy. The INR should be monitored more frequently during coadministration of warfarin. Patients should be advised to promptly report any signs of bleeding to their physician, including pain, swelling, headache, dizziness, weakness, prolonged bleeding from cuts, increased menstrual flow, vaginal bleeding, nosebleeds, bleeding of gums from brushing, unusual bleeding or bruising, red or brown urine, or red or black stools.

naproxen lansoprazole
Applies to: lansoprazole / naproxen and lansoprazole / naproxen
GENERALLY AVOID: Theoretically, proton pump inhibitors may decrease the gastrointestinal absorption of enteric-coated naproxen, which requires an acidic environment for dissolution. The proposed mechanism is an increase in gastric pH (i.e. decreased gastric acidity) induced by proton pump inhibitors. In patients treated with proton pump inhibitors, the possibility of a reduced or subtherapeutic response to enteric-coated naproxen should be considered.
MANAGEMENT: Concomitant use of these drugs is generally not recommended.

lansoprazole PONATinib
Applies to: lansoprazole / naproxen and Iclusig (ponatinib)
Coadministration with drugs that elevate the gastric pH such as proton pump inhibitors, H2-receptor antagonists, and antacids may decrease the oral bioavailability of ponatinib and reduce its concentrations in plasma. The aqueous solubility of ponatinib has been shown to be pH-dependent, with higher pH resulting in decreased solubility. However, in a drug interaction study in healthy volunteers, coadministration of ponatinib after multiple doses of lansoprazole resulted in a minor reduction in ponatinib Cmax but no change in overall systemic exposure (AUC) compared to ponatinib administered alone. Therefore, ponatinib may be coadministered with medicines that increase gastric pH without dose adjustment or separation of administration.

Drug and food interactions
PONATinib food
Applies to: Iclusig (ponatinib)
GENERALLY AVOID: Coadministration with grapefruit juice is likely to increase the plasma concentrations of ponatinib, which is primarily metabolized by CYP450 3A4. However, the interaction has not been studied. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit.
MANAGEMENT: The consumption of grapefruit, grapefruit juice, and supplements that contain grapefruit extract should be avoided during treatment with ponatinib.

naproxen food
Applies to: lansoprazole / naproxen
GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.
MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.
