Summary
Tolterodine is an oral antimuscarinic, and inhaled ipratropium adds a small amount of anticholinergic activity. Systemic ipratropium exposure is low, so a meaningful additive effect is unlikely at usual doses, though dry mouth or urinary retention could be slightly increased.
What this interaction means in plain words
Ipratropium-salbutamol and Tolterodine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Ipratropium-salbutamol belongs to Respiratory; Tolterodine belongs to Genitourinary.
Why it happens
Additive muscarinic receptor antagonism, limited by the low systemic absorption of inhaled ipratropium.
