Bael and Pralsetinib

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Pralsetinib

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

Bael and its constituents marmelosin and marmesinin inhibited cytochrome P450 3A4 (CYP3A4) activity in vitro. So far, this interaction has not been reported in humans. Theoretically, bael might increase levels of drugs metabolized by CYP3A4.
Some drugs metabolized by CYP3A4 include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and numerous others. Use bael cautiously or avoid in patients taking these drugs.
Severity Minor 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 pralsetinib (Gavreto): your body relies on a liver enzyme called CYP3A4 to clear it out. In lab tests (test tubes only, not in real people yet), compounds in bael appeared to slow that enzyme down. If that held true in the body, pralsetinib could build up a bit higher than expected, which in theory might mean more of its usual side effects like fatigue, high blood pressure, swelling, constipation, or changes in your blood counts.

The honest takeaway: this is a theoretical, lab-only concern with no human reports, so don't panic. But since pralsetinib is a serious cancer medicine, please run any bael supplement past your oncologist or pharmacist first. Occasional culinary amounts of the fruit are far less concerning than concentrated supplement doses.

From our pharmacist’s overview on the Pralsetinib page

“With pralsetinib (Gavreto), a targeted therapy for RET-driven lung and thyroid cancers, I would treat this list as required reading rather than background noise. Most of the interactions change how much of the drug the body actually gets: grapefruit can push its levels higher, while St.”

About Bael

What is Bael?

Bael
  • Diarrhea and dysentery
  • Indigestion and other digestive complaints
  • Constipation
  • Blood sugar support
  • General wellness in traditional medicine

Bael is a fruit-bearing tree long used in traditional Indian (Ayurvedic) medicine, mostly for digestive problems like diarrhea and indigestion. Modern human evidence for its medicinal benefits is very limited, so it should be viewed mainly as a food and traditional remedy rather than a proven treatment. Talk to your pharmacist or doctor before using bael as a supplement, especially if you are pregnant, breastfeeding, or have a health condition.

About Pralsetinib

What Is Pralsetinib Used For?

Brand name: Gavreto

Gavreto (pralsetinib) is used to treat adults with metastatic RET fusion-positive non-small cell lung cancer (NSCLC) — a type of lung cancer that has spread and carries a specific genetic alteration detected by an FDA-approved test.

Gavreto is also approved for adults and children aged 12 and older with advanced or metastatic RET fusion-positive thyroid cancer who need systemic (whole-body) treatment and whose cancer no longer responds to radioactive iodine (when radioactive iodine is an appropriate option). This thyroid cancer use is under accelerated approval, meaning continued approval depends on results from confirmatory clinical trials.
