Role of tiotropium in the treatment of COPD Rice KL; Kunisaki KM; Niewoehner DEInt J Chron Obstruct Pulmon Dis 2007[]; 2 (2): 95-105Tiotropium is a potent, long-acting, selective anticholinergic bronchodilator. Treatment with tiotropium produces sustained improvements in lung function, particularly FEV1 (peak, trough, average, and area under the curve) compared with either placebo or ipratropium in patients with moderate to severe COPD. Preliminary evidence suggests that treatment with tiotropium may slow the rate of decline in FEV1, but this finding awaits confirmation. Tiotropium reduces lung hyperinflation, with associated improvements in exercise capacity. Tiotropium, compared with either placebo or ipratropium, improves a variety of patient-centered outcomes, including subjective dyspnea ratings and HRQL scores. Tiotropium reduces the frequency of COPD exacerbations and of hospitalizations due to exacerbations, but has not been shown to reduce all-cause mortality. Compared with the long-acting bronchodilators, tiotropium provides incrementally better bronchodilation, but it is not clearly superior in terms of patient-centered outcomes. Tiotropium has a good safety profile; however patients with severe cardiac disease, bladder outlet obstruction, or narrow angle glaucoma were excluded from all studies. Medico economic analyses suggest that treatment with tiotropium may also be cost-effective, primarily by reducing costs associated with hospitalizations.|Adrenergic beta-Agonists/therapeutic use[MESH]|Bronchodilator Agents/adverse effects/economics/*therapeutic use[MESH]|Cholinergic Antagonists/adverse effects/economics/*therapeutic use[MESH]|Clinical Trials as Topic[MESH]|Cost-Benefit Analysis[MESH]|Drug Costs[MESH]|Drug Therapy, Combination[MESH]|Exercise[MESH]|Forced Expiratory Volume/drug effects[MESH]|Humans[MESH]|Lung/*drug effects/physiopathology[MESH]|Patient Selection[MESH]|Pulmonary Disease, Chronic Obstructive/*drug therapy/economics/physiopathology[MESH]|Respiratory Function Tests[MESH]|Scopolamine Derivatives/adverse effects/economics/*therapeutic use[MESH]|Tiotropium Bromide[MESH]|Treatment Outcome[MESH] |
