Cannabidiol (cbd) and Pitavastatin

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

Why Are There 2 Interactions?

Cannabidiol (cbd) interacts with whole categories of medication. Pitavastatin falls into 2 of those categories, so it can interact with Cannabidiol (cbd) 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 2C9 (CYP2C9) SUBSTRATES

1 of 2

Why this applies to Pitavastatin

Pitavastatin falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Cannabidiol (cbd) interacts with.

Cannabidiol may increase levels of drugs metabolized by CYP2C9.
In vitro and animal research shows that cannabidiol inhibits CYP2C9. In human studies, cannabidiol has been associated with an increase in plasma levels of topiramate and losartan, CYP2C9 substrates. Concomitant use of cannabidiol with CYP2C9 substrates may increase the risk for adverse effects from these substrates.
Severity Moderate Likelihood Probable Evidence A

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 gist: CBD can slow down a liver enzyme called CYP2C9, which is one of the pathways your body uses to clear pitavastatin. When that pathway gets blocked, more of the statin can linger in your bloodstream than usual. Pitavastatin is an active drug (not a prodrug), so higher levels generally mean a stronger effect and a bit more chance of side effects.

With statins, the things to watch for are muscle aches, weakness, or tenderness, and rarely problems showing up on liver bloodwork. The good news is this is usually manageable, not an emergency. We have solid research that CBD raises levels of other CYP2C9 drugs, so it's reasonable to be cautious here. Please don't stop or adjust anything on your own, just check with your pharmacist or doctor so they can keep an eye on you.

GLUCURONIDATED DRUGS

2 of 2

Pitavastatin also falls under GLUCURONIDATED DRUGS.

Cannabidiol might increase levels of certain glucuronidated drugs.
In vitro research shows that cannabidiol inhibits uridine diphosphoglucuronosyl transferase (UGT) 1A9 and UGT2B7, enzymes responsible for glucuronidation. Theoretically, this could decrease the clearance and increase levels of glucuronidated drugs.
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: pitavastatin is partly cleared from your body through a process called glucuronidation, and lab studies suggest CBD can slow down some of the enzymes (UGT1A9 and UGT2B7) that handle that step. In theory, if CBD blocks that pathway, pitavastatin could hang around a little longer and build up. With statins, higher levels can mean a bit more risk of muscle aches or, rarely, muscle pain that signals something more serious.

I want to be honest with you, though: this is only based on test-tube research, not real patients, so it's a maybe, not a sure thing. I wouldn't lose sleep over it, but if you're using a CBD product alongside your pitavastatin, mention it to your pharmacist or doctor and keep an eye out for any new muscle soreness or weakness.

From our pharmacist’s overview on the Pitavastatin page

“Liver strain runs through the serious end of pitavastatin's (Zypitamag, Nikita) supplement interactions, and this list deserves real care rather than a quick skim. The biggest cluster of worrisome entries is herbs and ingredients with their own record of liver injury, and alcohol belongs to that group too, with beer and wine both carry…”

About Cannabidiol (cbd)

What is Cannabidiol (cbd)?

  • Anxiety and stress
  • Sleep problems
  • Chronic pain
  • Certain seizure disorders
  • Inflammation

CBD is a compound from the cannabis (hemp) plant that does not cause a 'high.' It has strong evidence only for certain rare seizure disorders (as a prescription drug), while most other popular uses are still backed by limited or early research. Product quality varies a lot, so talk with your pharmacist or doctor before using it, especially if you take other medicines.

About Pitavastatin

What Is Pitavastatin Used For?

Brand names: Zypitamag, Nikita

Pitavastatin tablets are used alongside a cholesterol-lowering diet to reduce LDL-C (low-density lipoprotein, or "bad" cholesterol) in adults with primary hyperlipidemia (high cholesterol not caused by another disease).

Livalo, Pitavastatin Calcium (tablet), and some other pitavastatin tablet products are also approved for adults and children aged 8 years and older with heterozygous familial hypercholesterolemia (HeFH) — an inherited condition that causes very high LDL-C from birth. Zypitamag is labeled only for adults with primary hyperlipidemia; its labeling does not include the pediatric HeFH indication.
