Drug Interactions between aliskiren and vimseltinib

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with inhibitors of CYP450 3A4 and P-glycoprotein may increase the plasma concentrations and pharmacologic effects of aliskiren, which is a substrate of both the isoenzyme and efflux transporter. According to the product labeling, plasma levels of aliskiren were increased approximately 80% by the potent CYP450 3A4 and moderate P-gp inhibitor ketoconazole at a dosage of 200 mg twice daily. A 400 mg once daily dose of ketoconazole was not studied, but would be expected to further increase the magnitude of interaction. Similarly, plasma levels of aliskiren increased by approximately 2-fold when coadministered with the moderate CYP450 3A4 and potent P-gp inhibitor verapamil at a dosage of 240 mg once daily.

MANAGEMENT: Pharmacologic response to aliskiren should be monitored more closely whenever a CYP450 3A4 and/or P-gp inhibitor is added to or withdrawn from therapy, and the aliskiren dosage adjusted if necessary. Patients should be advised to notify their physician if they experience excessive adverse effects of aliskiren such as dizziness, lightheadedness, diarrhea, abdominal pain, and gastroesophageal reflux. The individual product labeling of the coadministered drug should be consulted for further guidance.
