Moderate

ANTICHOLINERGIC DRUGS

Why this applies to Aclidinium Bromide

Aclidinium Bromide falls under ANTICHOLINERGIC DRUGS — the group Datura Wrightii interacts with.

Datura wrightii contains atropine and scopolamine, as well as other tropane alkaloids with anticholinergic activity. Concomitant use of Datura wrightii with anticholinergic drugs might increase anticholinergic effects and adverse effects. Some anticholinergic drugs include amantadine, atropine, belladonna alkaloids, phenothiazines, scopolamine, and tricyclic antidepressants.
Severity Moderate 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

First things first: Datura wrightii is genuinely dangerous and not something I'd ever recommend swallowing, even in tiny amounts. With your inhaler, Tudorza Pressair (aclidinium), the concern here is that both work the same way. Aclidinium is an anticholinergic, meaning it blocks acetylcholine to relax the airways. Datura's tropane alkaloids (atropine, scopolamine) do the very same blocking, just throughout the whole body.

So stacking them could pile up those anticholinergic effects: dry mouth, blurry vision, a racing heart, constipation, trouble urinating, and confusion. This is based on how the two work rather than hard clinical studies, but the logic is sound. Aclidinium isn't a prodrug, so no flip in direction. Please don't combine these, and talk with your pharmacist or doctor first.

“Aclidinium Bromide (Tudorza Pressair) is an inhaled anticholinergic that keeps the airways open in COPD, and every one of the 30 supplements on this page acts on that same anticholinergic system. Two of them, henbane and scopolia, are rated major because their atropine-like alkaloids can pile onto the drug's effects with real force.”
