Glucosamine and Daunorubicin, Cytarabine

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

Moderate

TOPOISOMERASE II INHIBITORS

Why this applies to Daunorubicin, Cytarabine

Daunorubicin, Cytarabine falls under TOPOISOMERASE II INHIBITORS — the group Glucosamine interacts with.

Theoretically glucosamine may induce resistance to topoisomerase II inhibitors.
In vitro research suggests that glucosamine might induce resistance to etoposide (VP16, VePesid) and doxorubicin (Adriamycin) by reducing inhibition of topoisomerase II, an enzyme required for DNA replication in tumor cells. This effect 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

Vyxeos pairs daunorubicin with cytarabine to fight acute myeloid leukemia, and the daunorubicin part works by blocking an enzyme called topoisomerase II that cancer cells need to copy their DNA. The concern with glucosamine is that, in lab and animal studies, it seemed to help cancer cells resist that exact action. In theory, that could make the daunorubicin piece of your treatment work a little less well.

I want to be honest about the strength of this: it has only been seen in test-tube and animal research, never reported in real patients, so it is more of a 'better safe than sorry' caution. Still, because this is serious chemotherapy for a serious disease, please do not add glucosamine without first clearing it with your oncology team. They will give you the final word.

From our pharmacist’s overview on the Daunorubicin, Cytarabine page

“Vyxeos pairs daunorubicin and cytarabine to treat acute myeloid leukemia, and its supplement list is one to handle with genuine care. Most of it points at the liver: 38 of the 50 flagged ingredients can stress an organ already processing intensive chemotherapy, and the three rated major all belong to that group.”
