Lorbrena and Sonidegib

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.

Lorlatinib may significantly reduce the blood levels of sonidegib, which may make the medication less effective in treating your cancer. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact. 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.

GENERALLY AVOID: Coadministration with potent and moderate inducers of CYP450 3A4 may significantly decrease the plasma concentrations of sonidegib, which is primarily metabolized by the isoenzyme. In 16 healthy volunteers, administration of a single 800 mg dose of sonidegib five days after starting treatment with the potent CYP450 3A4 inducer rifampin (600 mg daily for 14 days) decreased mean sonidegib peak plasma concentration (Cmax) and systemic exposure (AUC) by 54% and 72%, respectively, compared to administration of sonidegib alone. Simulations using physiologically-based pharmacokinetic (PBPK) models suggest that sonidegib steady-state AUC would decrease 56% in cancer patients taking sonidegib 200 mg once daily with the moderate CYP450 3A4 inducer efavirenz for 14 days, and 69% when coadministered with efavirenz for 4 months.

MANAGEMENT: Concomitant use of sonidegib with potent and moderate CYP450 3A4 inducers should generally be avoided.
