Anhydrous Crystalline Maltose and Troglitazone

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

Minor

Antidiabetes Drugs

Why this applies to Troglitazone

Troglitazone falls under Antidiabetes Drugs — the group Anhydrous Crystalline Maltose interacts with.

Maltose, a disaccharide composed of two glucose molecules, has the potential to affect blood sugar levels similarly to table sugar (sucrose). While maltose itself does not necessarily interact directly with antidiabetic drugs, its digestion into glucose can lead to elevated blood sugar levels, which may impact the effectiveness of antidiabetic medications. In terms of effects on blood sugar, maltose may lead to a more rapid increase in blood sugar levels compared to sucrose, as it is directly converted into glucose. Individuals with diabetes should monitor their blood sugar levels closely when consuming foods or beverages containing maltose to maintain proper glucose control.
Severity Minor Likelihood Probable Evidence B

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 simple version: troglitazone (Rezulin) was a diabetes medicine that helped lower blood sugar. Maltose is a sugar, and when your body digests it, it breaks down into glucose, which is just blood sugar. So a maltose lozenge can nudge your blood sugar upward, which works against what your diabetes medicine is trying to do.

The good news is this is rated a minor interaction. There's no chemical clash where maltose changes how troglitazone is processed. It's really just the sugar load. The small amount in an occasional dry-mouth lozenge usually won't cause much, but if you use them regularly or have shaky control, keep an eye on your readings and check in with your pharmacist or doctor.

From our pharmacist’s overview on the Troglitazone page

“Most people taking troglitazone (Rezulin) are managing type 2 diabetes, and this list reflects that. The great majority of the 280 flagged ingredients act on blood sugar, most lowering it and a few raising it, so pairing them with a diabetes medication makes glucose control less predictable and can tip it too low.”

About Anhydrous Crystalline Maltose

What is Anhydrous Crystalline Maltose?

Anhydrous Crystalline Maltose
  • Dry mouth (xerostomia)
  • Sjögren syndrome
  • Dry mouth from medications
  • Food stabilizer and texturizer

Anhydrous crystalline maltose is a starch-derived sugar (also called malt sugar) studied mainly as a slow-dissolving lozenge to ease dry mouth, including in people with Sjögren syndrome. Some studies suggest it may modestly improve saliva flow, but the overall evidence is limited. It appears generally well tolerated, but talk with your pharmacist or doctor before using it, especially if you have diabetes.
