Atractylodes and Pitolisant Hydrochloride

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Pitolisant Hydrochloride

Pitolisant Hydrochloride falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Atractylodes interacts with.

Theoretically, atractylodes might increase the levels of CYP3A4 substrates.
In animals, atractylodes administered at high doses has been shown to inhibit CYP3A1 activity, which is a homolog to the human CYP3A4 enzyme. This effect has not been shown in humans.
Severity Minor 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: your body clears pitolisant (Wakix) partly through a liver enzyme called CYP3A4. In animal studies, high doses of atractylodes slowed down a similar enzyme. If that same thing happened in people, your pitolisant could clear a bit more slowly and build up slightly, which might nudge up its usual effects, things like headache, nausea, trouble sleeping, anxiety, or a faster heartbeat.

That said, I don't want to overstate this. This is purely theoretical, based only on lab and animal work, and it has never been shown in humans. Pitolisant is not a prodrug, so it works as-is. Food amounts in herbal cooking are very unlikely to matter. Still, it's worth a quick mention to your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Pitolisant Hydrochloride page

“Pitolisant (Wakix) keeps people with narcolepsy awake through the day, and it only works when a steady amount reaches the bloodstream. Most of the 158 supplement ingredients on this page can disturb exactly that, so this is a list worth slowing down for.”

About Atractylodes

What is Atractylodes?

Atractylodes
  • Digestive upset and poor appetite
  • Bloating and fluid retention
  • General fatigue or 'weakness'
  • Diarrhea
  • Support within traditional formulas

Atractylodes is a root used for centuries in traditional Chinese, Japanese, and Thai medicine, mostly for digestive complaints and fatigue, often as part of multi-herb formulas. Modern research is still early and mostly from lab and animal studies, so its true benefits in people are not well proven. If you want to try it, talk with a pharmacist or doctor first, and avoid it during pregnancy and breastfeeding.

About Pitolisant

What Is Pitolisant Used For?

Brand name: Wakix

Wakix (pitolisant) is used to treat two hallmark problems of narcolepsy: excessive daytime sleepiness (feeling overwhelmingly tired and unable to stay awake during the day) and cataplexy (sudden episodes of muscle weakness or loss of muscle control, often triggered by emotion). It is approved for adults and children 6 years of age and older.

Both uses are specific to Wakix tablets taken by mouth. The drug is not approved for sleepiness or cataplexy caused by conditions other than narcolepsy.
