How it works

• It's a long-acting anticholinergic (muscarinic antagonist) that relaxes muscles in the airways, keeping them open

  .

• Taken daily, it helps prevent symptoms like wheezing, shortness of breath, and chest tightness. 

Uses

• COPD: Maintenance treatment for bronchospasm, chronic bronchitis, and emphysema.
