Moringa and Niraparib Tosylate

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

Moderate

P-GLYCOPROTEIN SUBSTRATES

Why this applies to Niraparib Tosylate

Niraparib Tosylate falls under P-GLYCOPROTEIN SUBSTRATES — the group Moringa interacts with.

Theoretically, moringa leaf extract might increase the levels and clinical effects of P-glycoprotein substrates.
In vitro research shows that moringa leaf extract inhibits renal P-glycoprotein transport activity. So far, this reaction 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

Here's the gist for anyone on Zejula (niraparib). Your body uses a little cellular pump called P-glycoprotein to help move certain drugs around and clear them out. Lab studies suggest moringa leaf extract may slow that pump down. In theory, if the pump works less well, a drug like niraparib could build up a bit more in your system, which might mean stronger side effects such as nausea, fatigue, low blood counts, or higher blood pressure.

I want to be honest about the evidence here: this is based only on test-tube research, and it has not actually been seen in people. So it's a possible concern, not a proven one. Everyday food amounts of moringa are far less likely to matter than concentrated capsules. Since niraparib is a serious cancer medicine, please run any moringa supplement past your oncologist or pharmacist first.

From our pharmacist’s overview on the Niraparib Tosylate page

“Activated charcoal, popular for bloating and so-called detox routines, can trap niraparib (Zejula) in the gut before it absorbs, and St. John's wort can drive levels of the drug down another way.”

About Moringa

What is Moringa?

  • Nutritional supplement
  • Blood sugar support
  • Cholesterol support
  • Inflammation
  • Skin conditions

Moringa is a nutrient-rich plant whose leaves are widely used as a food and supplement, especially in parts of the world where malnutrition is common. Early research hints at possible benefits for blood sugar, cholesterol, and inflammation, but the human evidence is limited and not strong enough to recommend it as a treatment. Talk with your pharmacist or doctor before using moringa, especially if you are pregnant, breastfeeding, or taking medications.

About Niraparib

What Is Niraparib Used For?

Brand name: Zejula

Zejula is used as maintenance therapy — meaning it is taken after chemotherapy to help keep the cancer from coming back — for adults with advanced epithelial ovarian, fallopian tube, or primary peritoneal cancer. For first-line maintenance, Zejula is approved for patients whose cancer is HRD-positive (has certain DNA-repair defects, including BRCA mutations or genomic instability) and who have responded to their first round of platinum-based chemotherapy.

Zejula is also approved for maintenance treatment in adults with recurrent ovarian, fallopian tube, or primary peritoneal cancer that carries a germline BRCA mutation (an inherited change in the BRCA gene), when the cancer has responded to platinum-based chemotherapy. In both cases, a companion diagnostic test is required to confirm eligibility before starting Zejula.
