Interactions between your drugs
ticagrelor encorafenib
Applies to: Brilinta (ticagrelor), encorafenib
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration with potent inducers of CYP450 3A4 may significantly decrease the plasma concentrations of ticagrelor, which is primarily metabolized by the isoenzyme. In 14 healthy volunteers, administration of a single 180 mg oral dose of ticagrelor on day 12 of treatment with the potent CYP450 3A4 inducer rifampin (600 mg once daily for 14 days) decreased mean ticagrelor peak plasma concentration (Cmax), systemic exposure (AUC) and plasma half-life by 73%, 86% and 67%, respectively, compared to administration of ticagrelor alone. Mean Cmax of the major active metabolite was unchanged in the presence of rifampin, but mean AUC decreased by 46% and plasma half-life by 50%. Inhibition of platelet aggregation (IPA) was also assessed in the study. Mean IPA at 12 hours was 87% with ticagrelor alone versus 63% in combination with rifampin; corresponding values at 24 hours were 70% and 15%, respectively.
MANAGEMENT: Concomitant use of ticagrelor with potent CYP450 3A4 inducers should generally be avoided.
Drug and food interactions
encorafenib food
Applies to: encorafenib
You should preferably avoid consumption of grapefruit and grapefruit juice while taking encorafenib. Grapefruit and grapefruit juice can significantly increase the blood levels of encorafenib. This may increase the risk of serious side effects such as bleeding complications, eye and vision problems, liver problems, irregular heart rhythm, and development of new skin cancers. Talk to your doctor if you have any questions or concerns. 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.
