Interaction report

Terminalia and Pazopanib

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Terminalia interacts with whole categories of medication. Pazopanib falls into 2 of those categories, so it can interact with Terminalia in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

1 of 2

Why this applies to Pazopanib

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

Theoretically, use of Terminalia arjuna may increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that Terminalia arjuna extract inhibits CYP3A4 enzymes and reduces CYP3A4 substrate metabolism.
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 explains PharmD, Clinical Pharmacist

Here's the gist: your kidney cancer drug pazopanib (Votrient) is cleared from your body mainly by a liver enzyme called CYP3A4. Lab studies suggest Terminalia arjuna may slow that enzyme down. If it does, pazopanib could build up to higher levels than intended, which may mean stronger side effects like high blood pressure, diarrhea, nausea, fatigue, liver enzyme changes, or hair color changes.

I want to be honest about the strength of this, though. So far this is only seen in test-tube research, not in people, so we don't truly know how much it matters in real life. Pazopanib is a serious cancer medicine with a tricky safety profile, so please don't add Terminalia on your own. Run it by your oncologist or pharmacist first.

ANTICOAGULANT/ANTIPLATELET DRUGS

2 of 2

Pazopanib also falls under ANTICOAGULANT/ANTIPLATELET DRUGS.

Theoretically, concomitant use of Terminalia arjuna with anticoagulant or antiplatelet drugs may increase the risk of bleeding in some patients.
In vitro, Terminalia arjuna bark extract inhibits platelet aggregation, decreases platelet activation, and shows antithrombotic properties.
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 situation with combining Terminalia (arjuna) and pazopanib (Votrient). The interaction on file is really about bleeding risk. In lab studies, Terminalia arjuna appears to make platelets (the cells that help your blood clot) less sticky. Pazopanib, as a kinase inhibitor, can already carry its own bleeding risk, sometimes showing up as nosebleeds, easy bruising, or blood in the urine or stool. So the worry is that stacking these two could add up and make bleeding a bit more likely.

I'll be honest with you: this is theoretical, based only on lab work, not real patient studies, so I don't want to alarm you. Still, with a cancer therapy like this, it's worth a quick chat with your oncologist or pharmacist before adding Terminalia. Don't change anything on your own.

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction 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.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

From our pharmacist’s overview on the Pazopanib page

“Take a careful look before mixing supplements with pazopanib (Votrient), an oral pill for advanced kidney cancer and certain sarcomas. Fourteen of the 349 ingredients on file are rated major, grapefruit among them, since it can raise pazopanib levels enough to intensify side effects.”

About Terminalia

What is Terminalia?

Terminalia
  • Heart health and circulation
  • Digestive problems (constipation, diarrhea)
  • Cholesterol support
  • Antioxidant and anti-inflammatory support
  • Immune support

Terminalia is a group of traditional Ayurvedic tree species (most notably Terminalia arjuna) used for heart, digestive, and general wellness purposes. Some small studies suggest possible benefits for heart and cholesterol health, but the evidence is limited and not strong enough to recommend it as a treatment. Talk to your pharmacist or doctor before using it, especially if you have a heart condition.

About Pazopanib

What Is Pazopanib Used For?

Brand name: Votrient

Pazopanib tablets — sold as the brand Votrient and as generic pazopanib — are used to treat two types of advanced cancer in adults: advanced renal cell carcinoma (RCC), the most common form of kidney cancer, and advanced soft tissue sarcoma (STS) in patients who have already received prior chemotherapy.

Important limitation: Pazopanib has not been shown to work in adipocytic soft tissue sarcoma (a subtype involving fat cells) or in gastrointestinal stromal tumors (GISTs), so it is not used for those cancers.
