Padang Cassia and Mitapivat

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Mitapivat

Mitapivat falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Padang Cassia interacts with.

In vitro research shows that a methanol extract of Padang cassia inhibits cytochrome P450 3A4 (CYP3A4) activity. Theoretically, taking Padang cassia with CYP3A4 substrates might increase the effects and side effects of these substrates.
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 short version: your body clears mitapivat (Pyrukynd) using a liver enzyme called CYP3A4. Lab research suggests concentrated Padang cassia cinnamon may slow that enzyme down a bit. If that happened, mitapivat could build up slightly higher than expected, which in theory could mean more of its usual side effects, things like headaches, low energy, nausea, back or joint aches, or changes in certain hormones.

I want to be honest about the evidence, though. This is only a test-tube finding, not something proven in people, so it's more of a 'keep an eye on it' than an alarm. The cinnamon in your oatmeal or baking won't be a problem. If you're thinking about a daily concentrated cinnamon supplement, just run it by your pharmacist or doctor first.

About Padang Cassia

What is Padang Cassia?

  • Adding flavor to food
  • Digestive upset
  • Blood sugar support
  • Antimicrobial purposes
  • Antioxidant support

Padang Cassia is a type of cinnamon (Indonesian or Korintje cinnamon) grown mainly in Indonesia and used widely as a kitchen spice. As a supplement, evidence for health benefits like blood sugar control is limited and mixed, and like other cassia cinnamons it naturally contains coumarin, which can be harmful to the liver in large amounts. Use food amounts freely, but talk to a pharmacist or doctor before taking concentrated cinnamon supplements.

About Mitapivat

What Is Mitapivat Used For?

Brand name: Pyrukynd

Mitapivat is available as two separate branded products approved for different conditions. Pyrukynd is used to treat hemolytic anemia — a type of anemia caused by red blood cells breaking down too quickly — in adults who have pyruvate kinase (PK) deficiency, a rare inherited blood disorder. Aqvesme is used to treat anemia in adults with alpha- or beta-thalassemia, inherited conditions that affect how the body makes hemoglobin.

These are distinct approvals. Pyrukynd and Aqvesme are not interchangeable, and each is approved only for its specific indication.
