Summary
Belladonna alkaloids are systemic antimuscarinics that could add to the effects of ipratropium, but ipratropium is poorly absorbed, so a significant interaction is unlikely at usual doses.
What this interaction means in plain words
Belladonna alkaloids and Ipratropium have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Additive muscarinic receptor blockade limited by low systemic absorption of ipratropium.
