Interactions between your drugs

Major

aluminum hydroxide taletrectinib

Applies to: aluminum hydroxide and taletrectinib

ADJUST DOSING INTERVAL: Coadministration with antacids or other agents with acid neutralizing or reducing effects may decrease the gastrointestinal absorption and plasma concentrations of taletrectinib due to increased gastric pH. Taletrectinib displays pH-dependent aqueous solubility, with increased solubility at lower pH. The magnitude of interaction may be dose-dependent and related to the degree of acid suppression achieved.

MANAGEMENT: The possibility of a reduced or subtherapeutic response to taletrectinib should be considered during coadministration with antacids or other agents that can increase gastric pH. If an antacid is required, the antacid should be taken 2 hours before or 2 hours after administration of taletrectinib. The same precaution may be applicable to other drugs with antacid effects. Patients should be advised to contact their doctor if their symptoms worsen or their condition changes, as reduced drug absorption may lead to decreased therapeutic effectiveness.

Drug and food/lifestyle interactions

Major

aluminum hydroxide food/lifestyle

Applies to: aluminum hydroxide

GENERALLY AVOID: The concomitant administration of aluminum-containing products (e.g., antacids and phosphate binders) and citrates may significantly increase serum aluminum concentrations, resulting in toxicity. Citrates or citric acid are contained in numerous soft drinks, citrus fruits, juices, and effervescent and dispersible drug formulations. Citrates enhance the gastrointestinal absorption of aluminum by an unknown mechanism, which may involve the formation of a soluble aluminum-citrate complex. Various studies have reported that citrate increases aluminum absorption by 4.6- to 50-fold in healthy subjects. Patients with renal insufficiency are particularly at risk of developing hyperaluminemia and encephalopathy. Fatalities have been reported. Patients with renal failure or on hemodialysis may also be at risk from soft drinks and effervescent and dispersible drug formulations that contain citrates or citric acid. It is unknown what effect citrus fruits or juices would have on aluminum absorption in healthy patients.

MANAGEMENT: The concomitant use of aluminum- and citrate-containing products and foods should be avoided by renally impaired patients. Hemodialysis patients should especially be cautioned about effervescent and dispersible over-the-counter remedies and soft drinks. Some experts also recommend that healthy patients should separate doses of aluminum-containing antacids and citrates by 2 to 3 hours.

ADJUST DOSING INTERVAL: The administration of aluminum-containing antacids with enteral nutrition may result in precipitation, formation of bezoars, and obstruction of feeding tubes. The proposed mechanism is the formation of an insoluble complex between the aluminum and the protein in the enteral feeding. Several cases of esophageal plugs and nasogastric tube obstructions have been reported in patients receiving high-protein liquids and an aluminum hydroxide-magnesium hydroxide antacid or an aluminum hydroxide antacid.

MANAGEMENT: Some experts recommend that antacids should not be mixed with or given after high protein formulations, that the antacid dose should be separated from the feeding by as much as possible, and that the tube should be thoroughly flushed before administration.

taletrectinib food/lifestyle

Applies to: taletrectinib

GENERALLY AVOID: Coadministration with grapefruit juice may increase the plasma concentrations of taletrectinib. The proposed mechanism for the interaction is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice but has been reported for other CYP450 3A4 inhibitors. In a clinical study, taletrectinib peak plasma concentration (Cmax) increased by 1.8-fold and systemic exposure (AUC) increased by 3.3-fold following concomitant administration of itraconazole, a potent CYP450 3A inhibitor. According to the product labeling, administration of taletrectinib with a moderate CYP450 3A inhibitor is predicted to increase taletrectinib Cmax and AUC by up to 1.5- and 2.6-fold, respectively. Increased exposure to taletrectinib may increase the risk and/or severity of adverse effects such as hepatotoxicity with liver enzyme elevations, lung toxicities, QT prolongation, hyperuricemia, myalgia with creatine phosphokinase elevation, and skeletal fractures.

ADJUST DOSING INTERVAL: Coadministration with high-fat food (1000 calories, 50% fat) increased taletrectinib Cmax and AUC by 1.5-fold, and the predicted increase in the QTc interval is 20.5 msec.

MANAGEMENT: The manufacturer recommends avoiding food or drink containing grapefruit during treatment with taletrectinib. In addition, taletrectinib should be administered on an empty stomach at about the same time each day, at least 2 hours before or 2 hours after food intake.

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.
