Tolvaptan (Samsca) and Zorbtive

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Somatropin may reduce the blood levels of tolvaptan, which may make the medication less effective in some cases. Contact your doctor if your symptoms worsen or your condition changes. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of tolvaptan, which is primarily metabolized by the isoenzyme. When tolvaptan was administered with the potent CYP450 3A4 inducer rifampin, tolvaptan peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by approximately 85%.

MANAGEMENT: The potential for diminished pharmacologic effects of tolvaptan should be considered during coadministration with CYP450 3A4 inducers. Alternative treatments may be required if an interaction is suspected.
