The treatment of COPD involves the use of both short and long-acting bronchodilators: inhaled beta2-agonists (salbutamol, salmeterol) and anticholinergics (ipratropium, tiotropium). Corticosteriods, both systemic and inhaled, are used for anti-inflammatory effects. These medications improve symptoms and modestly delay disease progression (Gladysheva et al, 2010). However, it has also been found that slowing disease progression reduces mortality, but only if the patient has stopped smoking (Anthonisen et al, 2005).
