Tiotropium

Tiotropium is a long-acting, antimuscarinic bronchodilator used in the management of chronic obstructive pulmonary disease (COPD) and asthma. 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.

Tiotropium powder for inhalation is indicated for the maintenance of bronchospasm in COPD and to prevent exacerbations of COPD. A combination tiotropium and olodaterol metered inhalation spray is indicated for maintenance of COPD. A tiotropium inhalation spray is indicated for the maintenance of bronchospasm in COPD, to prevent exacerbations of COPD, and to treat asthma in patients 12 or more years old. A tiotropium metered inhalation spray is indicated for the maintenance of bronchospasm in COPD, to prevent exacerbations of COPD, and to treat asthma in patients 6 or more years old.
