Evodia and nilotinib

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Evodia interacts with whole categories of medication. nilotinib falls into 3 of those categories, so it can interact with Evodia in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS

1 of 3

Why this applies to nilotinib

nilotinib falls under CYTOCHROME P450 3A4 (CYP3A4) INHIBITORS — the group Evodia interacts with.

Theoretically, CYP3A4 inhibitors might increase the levels and clinical effects of evodia.
Animal research shows that concomitant administration of ketoconazole, a known CYP3A4 inhibitor, with the alkaloid constituents of evodia significantly increases the area under the curve (AUC), maximum concentration (Cmax), and half-life of these constituents.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's a twist worth understanding: in this case, the interaction works the other way around. Nilotinib (Tasigna) actually blocks the liver enzyme CYP3A4, which is the same enzyme that helps clear evodia's active compounds out of your body. So when you take them together, it's the evodia levels that could climb, not the nilotinib. With more evodia hanging around, you might notice stronger effects from the herb itself, or unexpected side effects.

I'll be honest, this is based only on animal and lab studies, so it's theoretical and the real-world impact in people isn't well known. Still, nilotinib is a serious cancer medicine, and herbal products can be unpredictable. Please check with your oncologist or pharmacist before combining the two.

QT INTERVAL-PROLONGING DRUGS

2 of 3

nilotinib also falls under QT INTERVAL-PROLONGING DRUGS.

Theoretically, evodia might have an additive effect with drugs that prolong the QT interval, potentially increasing the risk of ventricular arrhythmias.
Evodia has demonstrated dose-dependent activity as a proarrhythmic agent in animal and in vitro studies. Evodia infusion in animals extends the action duration potential and induces prolongation of the QT interval and Torsade de pointes.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know about nilotinib (Tasigna): it already carries a well-known warning about affecting your heart's rhythm. It can stretch out something called the QT interval, which is the timing of your heartbeat on an EKG. When that gets too long, it can rarely trigger a dangerous irregular heartbeat.

Evodia appears to do something similar in lab and animal studies, so the worry is that stacking the two could add up and raise that risk a little. This is theoretical so far, based on test tube and animal research rather than people, so I don't want to alarm you. Still, because nilotinib is already a heart-rhythm drug, I'd play it safe. Please check with your oncologist or pharmacist before pairing them.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

3 of 3

nilotinib also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, evodia might increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that evodia extract inhibits hepatic CYP3A4. This effect has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the basic idea with nilotinib (Tasigna). Your liver uses an enzyme called CYP3A4 to clear this drug out of your body. Lab studies suggest Evodia may slow that same enzyme down. If it does, nilotinib could build up to higher levels than expected, which may mean more side effects, like nausea, headache, fatigue, rash, or changes in your heart's rhythm (a QT prolongation that nilotinib already carries a warning about).

Now, the honest part: this is only seen in test tube research, not in people, so we don't truly know if it matters in real life. Still, since nilotinib is a serious cancer medicine where blood levels count, I'd play it safe. Please check with your oncologist or pharmacist before pairing it with Evodia.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

About Nilotinib

What Is Nilotinib Used For?

Brand name: Tasigna

  • Nilotinib is used to treat certain types of chronic myeloid leukemia (CML; a type of cancer of the white blood cells) who have recently found to have this condition in adults and children 1 year of age and older. It is also used to treat certain types of CML in adults whose disease could not be treated successfully with imatinib (Gleevec) or adults who cannot take imatinib because of side effects. Nilotinib is also used to treat certain types of CML in children 1 year of age or older whose disease could not be treated successfully with other tyrosine kinase inhibitor therapies or who cannot take these medications because of side effects. Nilotinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
