Scopolia and Aminoglutethimide

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

ANTICHOLINERGIC DRUGS

Why this applies to Aminoglutethimide

Aminoglutethimide falls under ANTICHOLINERGIC DRUGS — the group Scopolia interacts with.

The alkaloid constituents of scopolia, including hyoscyamine, scopolamine, and atropine, could potentiate the effects and adverse effects of anticholinergic drugs.
Severity Major Likelihood Probable Evidence D

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 situation with these two. Scopolia is packed with strong anticholinergic alkaloids (atropine, hyoscyamine, and scopolamine), the kind that dry you out and slow things down. The concern on file is that pairing it with a drug already known to carry anticholinergic-type effects could stack those effects on top of each other.

I'll be honest with you: this warning is theoretical, based on how these compounds behave rather than on real reports with Aminoglutethimide specifically. Still, doubling up on anticholinergic activity can lead to dry mouth, blurred vision, constipation, trouble urinating, a racing heartbeat, or confusion, especially in older folks. Since the raw plant is genuinely poisonous and hard to dose, please don't combine these on your own. Check with your doctor or pharmacist first.

From our pharmacist’s overview on the Aminoglutethimide page

“Aminoglutethimide (Cytadren) suppresses adrenal hormone output, and marked drowsiness is one of its hallmark side effects, which is exactly where most of its supplement interactions strike. Of the 134 ingredients on file, 78 add their own sedation, and that group holds most of the 9 major-rated entries; alcohol is the best studied, and…”

Scopolia is a poisonous plant in the nightshade family that contains powerful anticholinergic alkaloids like atropine, hyoscyamine, and scopolamine.
