Delta-9-tetrahydrocannabinol (thc) and Mitapivat

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Delta-9-tetrahydrocannabinol (thc) interacts with whole categories of medication. Mitapivat falls into 3 of those categories, so it can interact with Delta-9-tetrahydrocannabinol (thc) in 3 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) INDUCERS

1 of 3

Why this applies to Mitapivat

Mitapivat falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS — the group Delta-9-tetrahydrocannabinol (thc) interacts with.

Theoretically, CYP3A4 inducers might reduce the levels and clinical effects of THC.
THC is a substrate of CYP3A4 enzymes.
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 for this pairing. Mitapivat (Pyrukynd) can act as a mild CYP3A4 inducer, meaning it can speed up that liver enzyme. THC happens to be broken down by CYP3A4, so in theory mitapivat could clear THC out of your system a bit faster. The practical result would be a weaker or shorter THC effect, not a stronger one. So the concern here is mostly about THC doing less, rather than building up and causing problems.

I want to be honest that this is a theoretical interaction based on how the drugs work, not something proven in studies, so I wouldn't lose sleep over it. Still, since mitapivat is treating a real blood condition, please run your cannabis or dronabinol use by your pharmacist or doctor so they can keep an eye on things.

Moderate

CYTOCHROME P450 2C9 (CYP2C9) INDUCERS

2 of 3

Mitapivat also falls under CYTOCHROME P450 2C9 (CYP2C9) INDUCERS.

Theoretically, drugs that are CYP2C9 inducers might decrease the levels and clinical effects of THC.
THC is a substrate of CYP2C9 enzymes.
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 if you take Pyrukynd (mitapivat) and also use THC. In this case it's the medication affecting the supplement, not the other way around. Mitapivat can speed up an enzyme called CYP2C9, and THC is broken down by that same enzyme. So in theory, your body might clear THC a bit faster, meaning you could feel less of its usual effects (a weaker 'high' or less of whatever benefit you're seeking).

I want to be honest about the strength of this: it's theoretical, based on how these compounds work on paper, not on solid human studies. It also won't make your mitapivat less effective for your anemia. If you notice THC isn't working as expected, just have a quick chat with your pharmacist or doctor before changing anything.

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

3 of 3

Mitapivat also falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES.

Theoretically, THC may increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that cannabis containing THC might modestly inhibit the activity of CYP3A4 enzymes, which might decrease the metabolism of CYP3A4 substrates. It is unclear if this effect is due to THC, other constituents, or the combination. In vitro research also shows that cannabis extracts containing THC modestly inhibit the CYP3A4 metabolism of testosterone; extracts providing the specific cannabinoids cannabidiol (CBD) or cannabigerol (CBG) alone had stronger inhibitory effects than extracts containing both THC and CBD. Conversely, a crossover clinical study in healthy adults shows that oral THC does not inhibit CYP3A4.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist: your body uses an enzyme called CYP3A4 to clear mitapivat (Pyrukynd) out of your system. THC may slow that enzyme down a little, which in theory could let mitapivat build up slightly and nudge up its effects or side effects, things like headache, nausea, back pain, or trouble sleeping. Mitapivat is an active drug, not a prodrug, so more of it in your blood means a bit more drug effect, not less.

The good news is this concern is mostly theoretical. It comes from lab studies, and one human study actually showed oral THC did not block CYP3A4. So a real-world problem is unlikely. Still, since THC can affect your thinking and driving on its own, it's worth a quick chat with your pharmacist or doctor before combining the two.

About Delta-9-tetrahydrocannabinol (thc)

What is Delta-9-tetrahydrocannabinol (thc)?

Delta-9-tetrahydrocannabinol (thc)
  • Chronic or nerve pain
  • Nausea and vomiting from chemotherapy
  • Appetite loss and weight loss
  • Muscle spasticity
  • Sleep problems
  • Anxiety and stress

THC is the main mind-altering compound in cannabis and is best known for causing a 'high.' A prescription form (dronabinol) is approved for chemotherapy-related nausea and appetite loss, but for most other uses the evidence is mixed or limited, and THC can impair thinking and driving. It should be avoided in pregnancy and breastfeeding and used only with medical guidance.

About Mitapivat

What Is Mitapivat Used For?

Brand name: Pyrukynd

Mitapivat treats two distinct types of anemia in adults. Pyrukynd is used to treat hemolytic anemia (anemia caused by red blood cells breaking down too quickly) in adults with pyruvate kinase (PK) deficiency, a rare inherited red blood cell disorder. Aqvesme is used to treat anemia in adults with alpha- or beta-thalassemia, inherited blood conditions that reduce normal hemoglobin production.

These are separate approvals for separate products — Pyrukynd and Aqvesme are not interchangeable, and each is intended for its specific condition.
