Hu Zhang and Axitinib

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Axitinib

Axitinib falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Hu Zhang interacts with.

Theoretically, hu zhang might increase levels of drugs metabolized by CYP3A4.
Hu zhang contains the constituent resveratrol. In vitro research shows that resveratrol might inhibit the CYP3A4 enzyme. However, a clinical study in adults with NAFLD found that adding resveratrol 3000 mg daily for 8 weeks did not necessitate dose adjustments to any established medications metabolized by CYP3A4.
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 Inlyta (axitinib): your body clears it using a liver enzyme called CYP3A4. Hu Zhang contains resveratrol, which in lab studies can slow that same enzyme down. If that slowing happened in real life, axitinib could build up in your blood, and since it's not a prodrug, more drug means stronger effects and a higher chance of side effects like high blood pressure, fatigue, diarrhea, mouth sores, or hand-and-foot skin reactions.

That said, this is a theoretical concern based mostly on test-tube work, and one human study using high-dose resveratrol didn't force any dose changes. Still, because axitinib is a cancer drug with a narrow safety window, please loop in your oncologist or pharmacist before adding Hu Zhang.

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

By severity: 3 major · 94 moderate · 41 minor.

From our pharmacist’s overview on the Axitinib page

“Grapefruit is the first thing I would take off the table on axitinib (Inlyta), a targeted therapy for advanced kidney cancer. It blocks the liver enzyme (CYP3A4) that clears axitinib, so levels climb and side effects with them.”

  • Cough and respiratory symptoms (traditional)
  • Skin and joint conditions (traditional topical use)

Hu Zhang (Japanese knotweed root) is a traditional Chinese herb that is one of the richest natural sources of resveratrol and emodin. Some lab and early human research looks interesting for inflammation and heart health, but high-quality evidence in people is limited. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

About Axitinib

What Is Axitinib Used For?

Brand name: Inlyta

Axitinib (brand name Inlyta) is used to treat advanced renal cell carcinoma (RCC), a type of kidney cancer. Inlyta can be used as a first-line treatment — meaning the very first treatment you receive — when combined with either avelumab or pembrolizumab, two other cancer medicines.

Inlyta is also approved as a single agent (on its own) for patients with advanced RCC who have already tried one other systemic (body-wide) cancer therapy that did not work or stopped working.
