Interaction report

Evodia and Tivozanib Hydrochloride

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Evodia interacts with whole categories of medication. Tivozanib Hydrochloride falls into 2 of those categories, so it can interact with Evodia in 2 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) SUBSTRATES

1 of 2

Why this applies to Tivozanib Hydrochloride

Tivozanib Hydrochloride falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Evodia interacts with.

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

Your body relies on a liver enzyme called CYP3A4 to break down and clear tivozanib (Fotivda). In lab studies, compounds in evodia appear to slow that same enzyme down. If that held true in people, tivozanib could clear more slowly and build up to higher levels than expected, which may mean stronger side effects.

With tivozanib that could look like worse high blood pressure, fatigue, diarrhea, mouth sores, hand-foot skin reactions, or thyroid changes. I want to be honest though: this concern comes only from test-tube research, not from humans, so it's theoretical. Still, because this is a serious cancer medicine, please don't add evodia without first running it by your oncologist or pharmacist.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Tivozanib Hydrochloride also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, taking evodia with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
In vitro and animal studies show that rutaecarpine, a constituent of evodia, inhibits platelet aggregation.
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 gist for folks taking Fotivda (tivozanib). Tivozanib itself isn't a blood thinner, but as a cancer kinase inhibitor it can already raise the risk of bleeding and bruising on its own. The concern with Evodia is that one of its compounds, rutaecarpine, slowed down platelet clumping in lab and animal tests. Platelets are what help your blood form clots, so blocking them could, in theory, add to tivozanib's own bleeding tendency.

I want to be honest that this is a theoretical worry based only on test tube and animal work, not on human studies. Still, watch for things like easy bruising, nosebleeds, bleeding gums, or pink urine. Please loop in your oncology team or pharmacist before adding Evodia.

  • 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.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
