Ginger and Netupitant, Palonosetron (Oral)

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Netupitant, Palonosetron (Oral)

Netupitant, Palonosetron (Oral) falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Ginger interacts with.

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction 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 something worth knowing about Akynzeo (the netupitant and palonosetron combo). The netupitant part is cleared by a liver enzyme called CYP3A4, and ginger may nudge that enzyme in either direction. In the lab, ginger sometimes blocks CYP3A4, which could let netupitant build up and possibly add to side effects like headache, constipation, fatigue, or stomach upset. Other lab work suggests ginger might speed up the enzyme instead, which could make the drug clear faster and work a little less well.

The honest part: this is based on test-tube and animal data, with only a few unclear case reports, so it's far from proven. Food amounts of ginger are very unlikely to matter. Before using ginger supplements during chemo, just check with your oncology pharmacist or doctor.

About Netupitant and Palonosetron

What Is Netupitant and Palonosetron Used For?

Brand name: Akynzeo

Akynzeo capsules are used in adults to prevent both the short-term (acute) and longer-lasting (delayed) nausea and vomiting that can follow cancer chemotherapy — including, but not limited to, highly emetogenic (strongly nausea-causing) chemotherapy regimens. It is always taken together with the steroid dexamethasone.

Akynzeo capsules cover a broad range of chemotherapy regimens, including anthracycline plus cyclophosphamide-based regimens. Each ingredient targets a different stage: palonosetron addresses nausea and vomiting in the first 24 hours, while netupitant covers both the early and the delayed phase that can last several days after treatment.
