Guggul and nilotinib

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to nilotinib

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

Theoretically, guggul might reduce the effects of CYP3A4 substrates.
In vitro research shows that guggul constituents known as guggulsterones can induce CYP3A4.
Severity Moderate Likelihood Probable Evidence D

Interaction 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..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the concern with pairing guggul and nilotinib (Tasigna). Your body relies on a liver enzyme called CYP3A4 to break down nilotinib. Lab studies hint that the active compounds in guggul (guggulsterones) may speed that enzyme up. If that happens in real life, your body could clear nilotinib faster than intended, leaving lower levels in your blood. For a leukemia medication, that's the worry, because weaker drug levels could mean it doesn't control your CML as well as it should.

I want to be honest about the evidence: this is based only on test-tube and animal work, so it's theoretical, not proven in people. Still, nilotinib is too important to gamble with. Please don't start or stop anything on your own. Check with your oncologist or pharmacist before adding guggul.

About Nilotinib

What Is Nilotinib Used For?

Brand name: Tasigna

  • Nilotinib is used to treat certain types of chronic myeloid leukemia (CML; a type of cancer of the white blood cells) who have recently found to have this condition in adults and children 1 year of age and older. It is also used to treat certain types of CML in adults whose disease could not be treated successfully with imatinib (Gleevec) or adults who cannot take imatinib because of side effects. Nilotinib is also used to treat certain types of CML in children 1 year of age or older whose disease could not be treated successfully with other tyrosine kinase inhibitor therapies or who cannot take these medications because of side effects. Nilotinib is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells.
