Background And Purpose: The long-acting muscarinic antagonist tiotropium received an indication for the treatment of asthma from the FDA in 2015.

Methods: This paper summarizes much of the published findings on tiotropium and asthma and explores the heterogeneity of the asthma population vis-à-vis recent changes in guidelines for management of COPD. The accompanying case study provides an illustration of how tiotropium might be added to a patient's regimen appropriately.
