Drug interactions between encorafenib and Zymine HC

Results for the following 2 drugs:
encorafenib
Zymine HC (hydrocodone/pseudoephedrine/triprolidine)

Interactions between your drugs

Moderate

HYDROcodone encorafenib

Applies to: Zymine HC (hydrocodone / pseudoephedrine / triprolidine) and encorafenib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with encorafenib may alter the plasma concentrations of drugs that are primarily metabolized by CYP450 3A4, resulting in increased toxicity or decreased efficacy of these drugs. In vitro, encorafenib has been shown to be a time-dependent inhibitor as well as inducer of CYP450 3A4. However, no pharmacokinetic data are available from drug interaction studies.

MANAGEMENT: Concomitant use of encorafenib and sensitive CYP450 3A4 substrates or substrates with narrow therapeutic ranges should generally be avoided. These drugs include, but are not limited to: alfentanil, cisapride, colchicine, cyclosporine, fentanyl, ivacaftor, lovastatin, simvastatin, oral midazolam, triazolam, pimozide, quinidine, sildenafil, ergot derivatives, macrolide immunosuppressants, and vinca alkaloids.

Drug and food interactions

Major

HYDROcodone food

Applies to: Zymine HC (hydrocodone / pseudoephedrine / triprolidine)

Do not use alcohol or medications that contain alcohol while you are receiving treatment with HYDROcodone. This may increase nervous system side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. If you are taking certain long-acting formulations of hydrocodone, consumption of alcohol may also cause rapid release of the drug, resulting in high blood levels that may be potentially lethal. Likewise, you should avoid consuming grapefruit and grapefruit juice, as this may increase the blood levels and effects of hydrocodone. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Do not use more than the recommended dose of HYDROcodone, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.

encorafenib food

Applies to: encorafenib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with potent or moderate inhibitors of CYP450 3A4 may significantly increase the plasma concentrations of encorafenib, which is primarily metabolized by the isoenzyme. When a single 50 mg dose of encorafenib (equivalent to 0.1 times the recommended dose) was administered with posaconazole, a potent CYP450 3A4 inhibitor, encorafenib peak plasma concentration (Cmax) increased by 68% and systemic exposure (AUC) increased by 3-fold. When the same dose of encorafenib was administered with diltiazem, a moderate CYP450 3A4 inhibitor, encorafenib Cmax increased by 45% and AUC increased by 2-fold. Increased exposure to encorafenib may increase the risk of serious and life-threatening adverse effects such as hemorrhage, uveitis, QT prolongation, hepatotoxicity, dermatologic reactions, and new malignancies.

MANAGEMENT: Concomitant use of encorafenib with grapefruit or grapefruit juice should generally be avoided. If coadministration is required, the manufacturer recommends reducing the encorafenib dose to one-third of the dose used prior to addition of a potent CYP450 3A4 inhibitor or one-half of the dose used prior to addition of a moderate CYP450 3A4 inhibitor. After the inhibitor has been discontinued for 3 to 5 elimination half-lives, the encorafenib dose that was taken prior to initiating the inhibitor may be resumed.

Moderate

triprolidine food

Applies to: Zymine HC (hydrocodone / pseudoephedrine / triprolidine)

Alcohol can increase the nervous system side effects of triprolidine such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with triprolidine. Do not use more than the recommended dose of triprolidine, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.

Therapeutic duplication warnings are only returned when drugs within the same group exceed the recommended therapeutic duplication maximum.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
