Gum Arabic and Gemtuzumab

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

Moderate

ORAL DRUGS

Why this applies to Gemtuzumab

Gemtuzumab falls under ORAL DRUGS — the group Gum Arabic interacts with.

Theoretically, gum arabic can alter the absorption of oral drugs due to its fiber content.
Gum arabic has been used as a suspending osmotic agent in drug formulations. It might improve bioavailability of water-insoluble drugs like naproxen, but reduce absorption of polar drugs like amoxicillin. To avoid changes in absorption, take gum arabic 30-60 minutes after oral medications.
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

Here's something worth clearing up. The interaction on file talks about gum arabic affecting oral medicines by changing how the gut absorbs them. But gemtuzumab (Mylotarg) isn't a pill you swallow. It's given as an infusion directly into a vein at an infusion center, so it never passes through your stomach or intestines. That means the fiber-and-absorption concern simply doesn't apply here.

So in practical terms, gum arabic taken by mouth shouldn't interfere with how gemtuzumab works. That said, anyone going through AML treatment has a lot going on, and your body may be sensitive. Before adding any supplement, including gum arabic, please run it by your oncologist or pharmacist first so it fits safely with your full chemo plan.

From our pharmacist’s overview on the Gemtuzumab page

“Activated charcoal is the one entry here I would not gloss over. It is the sole major-rated interaction with gemtuzumab (Mylotarg), an IV chemotherapy for acute myeloid leukemia, and the concern is that charcoal can lower exposure to many drugs, even ones not given by mouth, because it traps compounds that recirculate between the gut a…”

About Gum Arabic

What is Gum Arabic?

Gum Arabic
  • Digestive and gut health
  • Source of soluble fiber
  • Constipation or bowel regularity
  • Prebiotic support
  • Cholesterol support
  • Blood sugar support

Gum arabic is a soluble dietary fiber from the acacia tree that is widely used as a safe food additive and is sometimes taken as a supplement for digestive health and as a prebiotic. Early studies suggest possible benefits for gut bacteria, cholesterol, and blood sugar, but the evidence is limited, and high doses can cause gas and bloating. Talk to your pharmacist or doctor before using it as a supplement.
