Licorice and Ensartinib

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

Why Are There 2 Interactions?

Licorice interacts with whole categories of medication. Ensartinib falls into 2 of those categories, so it can interact with Licorice 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 Ensartinib

Ensartinib falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Licorice interacts with.

Theoretically, licorice might increase or decrease levels of drugs metabolized by CYP3A4.
Pharmacokinetic research shows that the licorice constituent glycyrrhizin, taken in a dosage of 150 mg orally twice daily for 14 days, modestly decreases the area under the concentration-time curve of midazolam by about 20%. Midazolam is a substrate of CYP3A4, suggesting that glycyrrhizin modestly induces CYP3A4 activity. Animal research also shows that licorice extract from the species G. uralensis induces CYP3A4 activity. However, licorice extract from G. glabra species appear to inhibit CYP3A4-induced metabolism of testosterone in vitro. It is thought that the G. glabra inhibits CYP3A4 due to its constituent glabridin, which is a moderate CYP3A4 inhibitor in vitro and not present in other licorice species. Until more is known, licorice should be used cautiously in people taking CYP3A4 substrates.
Severity Moderate Likelihood Possible Evidence B

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

Ensartinib (Ensacove) is a targeted cancer medicine (an ALK inhibitor) that your liver clears using an enzyme called CYP3A4. Licorice can nudge this enzyme, but the direction isn't clear-cut. Some licorice appears to speed the enzyme up, which could lower ensartinib levels and, in theory, make it work less well against your cancer. Other licorice (the G. glabra type, high in glabridin) may slow the enzyme in lab studies, which could raise levels and worsen side effects like rash, nausea, swelling, or liver strain.

Honestly, this is mostly theoretical and based on limited data, so I wouldn't panic. Still, with a cancer drug you don't want surprises. Please run any licorice supplement by your oncologist or pharmacist first.

P-GLYCOPROTEIN SUBSTRATES

2 of 2

Ensartinib also falls under P-GLYCOPROTEIN SUBSTRATES.

Theoretically, licorice might decrease the absorption of P-glycoprotein substrates.
In vitro research shows that licorice can increase P-glycoprotein activity.
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

Ensartinib (Ensacove) is a targeted cancer pill for certain lung cancers, and it happens to be carried in and out of your gut cells by a little pump called P-glycoprotein. Here's the concern with licorice: lab studies suggest that licorice may rev up that pump. If the pump works harder, it could push more ensartinib back out of your intestines before it's absorbed, meaning less of the drug actually makes it into your bloodstream.

In plain terms, that could mean your cancer medicine works less well over time, which is not something you want to risk. I'll stress, though, that this is only theoretical, based on test-tube research, not real patients. Even so, with a cancer drug this matters. Please check with your oncologist or pharmacist before using any licorice supplement, especially concentrated glycyrrhizin products.

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.
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.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.

From our pharmacist’s overview on the Ensartinib page

“Ensartinib (Ensacove) holds ALK-positive lung cancer in check, and I read this page as a genuine warning rather than fine print. Most of the entries can change how much of the drug actually reaches the bloodstream, because the body clears ensartinib through the CYP3A4 enzyme.”

About Licorice

What is Licorice?

Licorice
  • Sore throat and cough
  • Heartburn and stomach upset
  • Mouth ulcers and digestive complaints
  • Inflammation
  • Traditional tonic/adrenal support

Licorice root is a traditional remedy used for sore throats, coughs, and digestive complaints, but solid human evidence is limited for most uses. Regular licorice contains glycyrrhizin, which can raise blood pressure and lower potassium when taken in large amounts or for a long time, so deglycyrrhizinated (DGL) products are often preferred. Talk to your pharmacist or doctor before using it, especially if you have high blood pressure, heart, or kidney problems.
