Delta-9-tetrahydrocannabinol (thc) and Budenoside

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Budenoside

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

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

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

Here's the gist for budesonide (Pulmicort): your liver uses an enzyme called CYP3A4 to clear it out. Lab tests suggest THC might slow that enzyme down a little, which could let budesonide build up slightly more than usual. In theory, that means a touch more steroid effect from the same dose.

Honestly though, I wouldn't lose sleep over this one. The evidence is just test-tube data, the interaction is rated minor and unlikely, and one human study found oral THC didn't block CYP3A4 at all. With inhaled Pulmicort, the amount reaching your bloodstream is small to begin with. If you ever notice things like a hoarse voice, oral thrush, or more side effects, mention it to your pharmacist or doctor.

From our pharmacist’s overview on the Budenoside page

“Budesonide (Pulmicort Flexhaler, Pulmicort Turbuhaler) is an inhaled steroid for asthma, and the 138 supplements on this page deserve genuine attention because the drug is cleared almost entirely by one liver enzyme, CYP3A4. Nearly every entry here changes how fast that enzyme works.”

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.
