Tiotropium acts mainly on M3 muscarinic receptors located in the airways to produce smooth muscle relaxation and bronchodilation.  Tiotropium is more specific for the subset of muscarinic receptors commonly found in the lungs than [ipratropium].  Tiotropium was granted FDA approval on 30 January 2004."}]
