Interaction Effect

Decreased ponatinib efficacy

Interaction Summary

Concomitant use of ponatinib and agents that elevate gastric pH may decrease ponatinib efficacy. The solubility of ponatinib is pH-dependent. Relative to administration of ponatinib alone, coadministration of a single dose of ponatinib 45 mg in the presence of lansoprazole 60 mg daily in healthy volunteers (n=18) decreased ponatinib AUC by 6% and Cmax by 25%. Despite this interaction, the change in ponatinib exposure is minimal and ponatinib may still be administered concomitantly with these agents. Consider monitoring for lack of response to ponatinib.

How To Manage Interaction

Concomitant use of ponatinib and agents that elevate gastric pH may decrease ponatinib efficacy; however, the change in exposure is minimal and ponatinib may still be administered concomitantly with these agents. Consider monitoring for lack of response to ponatinib.

Mechanism Of Interaction

Elevation of gastric pH

Omeprazole Overview

• Prescription omeprazole is used alone or with other medications to treat the symptoms of gastroesophageal reflux disease (GERD), a condition in which backward flow of acid from the stomach causes heartburn and possible injury of the esophagus (the tube between the throat and stomach) in adults and children 1 year of age and older. Prescription omeprazole is used to treat damage from GERD in adults and children 1 month of age and older. Prescription omeprazole is used to allow the esophagus to heal and prevent further damage to the esophagus in adults and children 1 year of age and older with GERD. Prescription omeprazole is also used to treat conditions in which the stomach produces too much acid such as Zollinger-Ellison syndrome in adults. Prescription omeprazole is also used to treat ulcers (sores in the lining of the stomach or intestine) and it is also used with other medications to treat and prevent the return of ulcers caused by a certain type of bacteria (H. pylori) in adults. Nonprescription (over-the-counter) omeprazole is used to treat frequent heartburn (heartburn that occurs at least 2 or more days a week) in adults. Omeprazole is in a class of medications called proton-pump inhibitors. It works by decreasing the amount of acid made in the stomach.

Ponatinib Overview

• Ponatinib is used to treat certain types of chronic myeloid leukemia (CML; a type of cancer of the white blood cells), including treatment in people who can no longer benefit from other medications for CML or who cannot take these medications because of side effects. Ponatinib is also used to treat certain types of acute lymphoblastic leukemia (ALL; a type of cancer of the white blood cells) in people who can no longer benefit from other medications for leukemia or who cannot take these medications because of side effects. Ponatinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps stop the spread of cancer cells.

Definitions

Severity Categories

Contraindicated

These drugs, generally, should not be used together simultaneously due to the high risk of severe adverse effects. Combining these medications can lead to dangerous health outcomes and should be strictly avoided unless otherwise instructed by your provider.

Major

This interaction could result in very serious and potentially life-threatening consequences. If you are taking this drug combination, it is very important to be under close medical supervision to minimize severe side effects and ensure your safety. It may be necessary to change a medication or dosage to prevent harm.

Moderate

This interaction has the potential to worsen your medical condition or alter the effectiveness of your treatment. It's important that you are monitored closely and you potentially may need to make adjustments in your treatment plan or drug dosage to maintain optimal health.

Minor

While this interaction is unlikely to cause significant problems, it could intensify side effects or reduce the effectiveness of one or both medications. Monitoring for changes in symptoms and your condition is recommended, and adjustments may be made if needed to manage any increased or more pronounced side effects.

Onset

Rapid: Onset of drug interaction typically occurs within 24 hours of co-administration.

Delayed: Onset of drug interaction typically occurs more than 24 hours after co-administration.

Evidence

Level of documentation of the interaction.

Established: The interaction is documented and substantiated in peer-reviewed medical literature.

Theoretical: This interaction is not fully supported by current medical evidence or well-documented sources, but it is based on known drug mechanisms, drug effects, and other relevant information.
