Breadfruit and Rosiglitazone Maleate

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

Moderate

CYTOCHROME P450 2C8 (CYP2C8) SUBSTRATES

Why this applies to Rosiglitazone Maleate

Rosiglitazone Maleate falls under CYTOCHROME P450 2C8 (CYP2C8) SUBSTRATES — the group Breadfruit interacts with.

Breadfruit might increase the levels of drugs metabolized by cytochrome P450 2C8 (CYP2C8) enzymes. So far, this interaction has not been reported in humans. However, in vitro evidence shows that the breadfruit constituent artocarpin inhibits CYP2C8 enzymes, which might increase the levels of CYP2C8 substrates. Some drugs metabolized by CYP2C8 include amiodarone (Cardarone), paclitaxel (Taxol); nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac (Voltaren) and ibuprofen (Motrin), rosiglitazone (Avandia), and others.
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 with rosiglitazone (Avandia) and breadfruit. Your liver uses an enzyme called CYP2C8 to clear rosiglitazone out of your system. A compound in breadfruit leaves, artocarpin, has been shown in lab studies to slow that same enzyme down. If that happened in your body, rosiglitazone could build up a bit more than expected, which in theory could nudge up the risk of side effects like low blood sugar, fluid retention, swelling in the legs, or weight gain.

The honest part: this has only been seen in test-tube research, never in real people, so it's far from proven. Eating breadfruit as a normal food is very unlikely to cause trouble. Concentrated leaf teas or extracts are the bigger question mark. Before using those, check in with your pharmacist or doctor.

From our pharmacist’s overview on the Rosiglitazone Maleate page

“Rosiglitazone (Avandia) lowers blood sugar in type 2 diabetes, and most of the 314 supplements and herbs on this page pull on that same lever. Some 239 can move blood glucose on their own, so adding one risks hypoglycemia, the shakiness, sweating, and confusion of sugar falling too low.”

About Breadfruit

What is Breadfruit?

  • Source of nutrition and energy
  • High blood pressure
  • Diabetes and blood sugar support
  • Inflammation and joint discomfort
  • Skin conditions

Breadfruit is a starchy tropical fruit eaten as a staple food, and its leaves are used in traditional medicine for conditions like high blood pressure and diabetes. As a food it is nutritious and generally safe, but the medicinal use of leaf teas or extracts has very little human research to back it up. Talk with your pharmacist or doctor before using breadfruit products for a health condition.

About Rosiglitazone

What Is Rosiglitazone Used For?

Brand name: Avandia

  • Rosiglitazone is used along with a diet and exercise program and sometimes with one or more other medications to treat type 2 diabetes (condition in which the body does not use insulin normally and therefore cannot control the amount of sugar in the blood). Rosiglitazone is in a class of medications called thiazolidinediones. It works by increasing the body's sensitivity to insulin, a natural substance that helps control blood sugar levels. Rosiglitazone is not used to treat type 1 diabetes (condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood) or diabetic ketoacidosis (a serious condition that may occur if high blood sugar is not treated).

  • Over time, people who have diabetes and high blood sugar can develop serious or life-threatening complications, including heart disease, stroke, kidney problems, nerve damage, and eye problems. Taking medication(s), making lifestyle changes (e.g., diet, exercise, quitting smoking), and regularly checking your blood sugar may help to manage your diabetes and improve your health. This therapy may also decrease your chances of having a heart attack, stroke, or other diabetes-related complications such as kidney failure, nerve damage (numb, cold legs or feet; decreased sexual ability in men and women), eye problems, including changes or loss of vision, or gum disease. Your doctor and other healthcare providers will talk to you about the best way to manage your diabetes.
