Tiotropium; more knowledge leads to more questions This issue of the International Journal of COPD has 3 original research papers that study the effects of tiotropium. These papers are very different, addressing the effect of tiotropium on the small airways (Incorvaia et al 2008), the benefi t of additional tiotropium treatment during a pulmonary rehabilitation programme (Kesten et al 2008), an...

BACKGROUND Tiotropium bromide is an effective therapy for COPD patients. Comparing across programs tiotropium Respimat Soft Mist inhaler was at least as efficacious as tiotropium HandiHaler, however, concerns have been raised about tiotropium's safety when given via Respimat. METHODS The TIOSPIR trial (NCT01126437) compares the safety and efficacy of tiotropium Respimat 5 μg once daily (marke...

Although bronchial hyperresponsiveness to cholinergic agents is a main feature of asthma, the role of anticholinergic drugs in chronic asthma management has been largely underestimated. Several single-dose studies comparing acute bronchodilation induced by ipratropium bromide with salbutamol have shown that salbutamol is more effective than ipratropium in treating asthma. Recently, tiotropium h...

BACKGROUND Tiotropium Safety and Performance in Respimat® (TIOSPIR®) compared the safety and efficacy of tiotropium Respimat® and tiotropium HandiHaler® in patients with chronic obstructive pulmonary disease (COPD). A prespecified spirometry substudy compared the lung function efficacy between treatment groups. METHODS TIOSPIR® was a large-scale, long-term (2.3-year), event-driven, randomized...

The aim of this study was to perform a 1-yr trial-based cost-effectiveness analysis (CEA) of tiotropium versus salmeterol followed by a 5-yr model-based CEA. The within-trial CEA, including 7,250 patients with moderate to very severe chronic obstructive pulmonary disease (COPD), was performed alongside the 1-yr international randomised controlled Prevention of Exacerbations with Tiotropium (POE...

BACKGROUND In Korea, patients with destroyed lung due to tuberculosis (TB) account for a significant portion of those affected by chronic pulmonary function impairment. The objective of our research was to evaluate the efficacy of inhaled tiotropium bromide in TB destroyed lung. METHODS We compared the effectiveness of inhaled tiotropium bromide for 2 months between pre- and post-treatment pu...

Chronic obstructive pulmonary disease (COPD) patients experiencing frequent exacerbations demonstrate increased stable-state airway inflammation. Tiotropium has been shown to reduce exacerbation frequency, but its effect on airway inflammation is unknown. The aim of the present study was to investigate the effect of tiotropium on sputum inflammatory markers and exacerbation frequency. Patients ...

The long-acting anticholinergic agent tiotropium bromide (Spiriva(®)) is available as a solution for inhalation via Respimat(®) Soft Mist™ Inhaler in the EU and various other countries for the treatment of chronic obstructive pulmonary disease (COPD). With the Respimat(®) Soft Mist™ Inhaler there is improved lung deposition of drug (allowing a reduced dosage compared with tiotropium HandiHaler(...

As a potent bronchodilator, the anti-inflammatory effects of tiotropium and its interaction with budesonide against cadmium-induced acute pulmonary inflammation were investigated. Compared to values obtained in rats exposed to cadmium, cytological analysis indicated a significant decrease of total cell and neutrophil counts and protein concentration in bronchoalveolar lavage fluid (BALF) in rat...

The aim of the present study was investigate the long-term effect of tiotropium as first maintenance respiratory medication in chronic obstructive pulmonary disease (COPD). A 4-yr, randomised, multicentre, double-blind, parallel-group, placebo-controlled trial (Understanding Potential Long-term Impacts on Function with Tiotropium (UPLIFT) was conducted. Analysis focused on the effect of tiotrop...
