amirmullick3 Who said not to use it in old people? Remember "I pray that tio can breathe soon" and tio is an old uncle in spanish but its also the other drug, tiotrropium. +4

drdoom discussion of anticholinergics & elderly also discussed at some length (but different context) here: https://www.nbmeanswers.com/exam/nbme22/1288 +1
