OBJECTIVETo evaluate the efficacy and safety of tiotropium in treatment of severe persistent asthma.

METHODSReports of randomized controlled trials (RCTs) describing tiotropium for treatment of severe persistent asthma published from January 1946 to February 2015 were searched in Cochrane Library, ClinicalTrials.gov, PubMed, Ovid Medline, CNKI, and CSJD. The data of the included RCTs were extracted and the data quality was evaluated. Meta-analyses were performed with Revman 5.3 software.

RESULTSFive RCTs including 1433 patients were analyzed. Meta-analysis of the data showed that compared with the placebo group, tiotropium treatment significantly improved the patients' peak forced expiratory volume in one second (FEV1) [weighted mean difference (WMD): 0.13 L, 95% confidence interval (CI): 0.10-0.16 L, P<0.00001], trough FEV1 (WMD: 0.09 L, 95%CI: 0.06-0.12 L, P<0.00001), peak forced vital capacity (FVC) (WMD: 0.10 L, 95%CI: 0.06-0.14 L, P<0.00001), trough FVC (WMD: 0.12 L, 95%CI: 0.08-0.17 L, P<0.00001), morning peak expiratory flow (PEF) (WMD: 9.21 L/min, 95%CI: 4.2-14.23 L/min, P=0.0003), evening PEF (WMD: 22.06 L/min, 95%CI 13.05-31.08 L/min, P<0.00001). The scores of asthma control questionnaire (ACQ) (WMD: 0.01, 95% CI: -0.07-0.09, P=0.86) or asthma quality of life questionnaire (AQLQ)(WMD: 0.06, 95% CI:-0.18-0.06, P=0.33) were not affected by tiotropium. No significant difference with adverse events between tiotropium group and placebo group were reported in these included studies (P>0.05).

CONCLUSIONSTiotropium for severe persistent asthma treatment can improve FEV1, FVC, and PEF but may not improve the quality of life of the patients. Tiotropium is well tolerated and can be an add-on therapy for severe persistent asthma.

OBJECTIVE: International institutes such as Global institute for Asthma(GINA), KAAACI(Republic of Korea), NHLBI(USA), BTS(UK) and JSA(Japan) have published guidelines for asthma treatment. The aim of this study was to compare the representatives' international guidelines of pharmacotherapy for pediatric asthma. METHODS: The recommendations related to pharmacotherapy for pediatric asthma were extracted from the latest representatives' international guidelines, and comprehensive comparisons were conducted. RESULTS: Major comparison outcomes between international guidelines were evaluated as follows: classification system on severity and pediatric age group, recommendation for inhaled corticosteroid dose, recommendation for pediatric age group of theophylline in mild asthma, and recommendation for pediatric age group of tiotropium in severe asthma. Clinical trials emphasized the adverse effects of theophylline, whereas tiotropium demonstrated beneficial actions for pediatric asthma. Therefore, theophylline was recommended for older patients with persistent asthma, and tiotropium was considered to be suitable for younger patients with severe asthma according to GINA guidelines. CONCLUSION: These findings address the requirement to harmonize international guidelines of pharmacotherapy in pediatric asthma. In addition, the findings suggest that KAAACI needs to update its pharmacotherapy guidelines of theophylline, tiotropium and other medicines recently approved.

Asthma is a chronic respiratory disease characterized by reversible airway obstruction that is secondary to an allergic inflammation and excessive smooth muscle contraction. Cholinergic signals were known to contribute significantly to the pathophysiology of asthma. However, the use of anti-cholinergic agents in asthma has been justified only in acute asthma exacerbations, until tiotropium bromide, a long-acting anti-cholinergic agent was introduced. Recent reports showing a promising role of tiotropium in the treatment of asthma have aroused interest of the use of anti-cholinergic agent for the management of asthma. This report describes pharmacological characteristics, potential effects on inflammatory cells, and the current status of tiotropium in the treatment of asthma.

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 pulmonary function tests performed on 29 patients with destroyed lung due to TB. RESULTS: The mean age of the total number of patients was 63+/-9 years, where 15 patients were male. The pre-treatment mean forced expiratory volume in 1 second (FEV1) was 1.02+/-0.31 L (44.1+/-16.0% predicted). The pre-treatment mean forced vital capacity (FVC) was 1.70+/-0.54 L (52.2+/-15.8% predicted). Overall, the change in FEV1% predicted over baseline with tiotropium was 19.5+/-19.1% (p<0.001). Twenty patients (72%) got better than a 10% increase in FEV1 over baseline with tiotropium, but one patient showed more than a 10% decrease in FEV1. Overall, the change in FVC% predicted over baseline with tiotropium was 18.5+/-19.9% (p<0.001). Seventeen patients (59%) experienced greater than a 10% increase in FVC over baseline with tiotropium; 12 (41%) patients had stable lung function. CONCLUSION: The inhaled tiotropium bromide therapy may lead to improve lung functions in patients with TB destroyed lung. However, the long-term effectiveness of this treatment still needs to be further assessed.

Despite a range of efficacious therapies for asthma, including inhaled corticosteroids (ICS) and long-acting β₂-agonists (LABA), a significant proportion of patients have poor asthma control and retain a risk of future worsening of their symptoms. Long-acting muscarinic antagonist (LAMA) bronchodilators offer a well-tolerated, efficacious, and cost-effective add-on to a patient's treatment. Of the LAMAs currently under investigation or available for the treatment of asthma, evidence from a comprehensive clinical trial program in adults and children shows that once-daily treatment with tiotropium provides benefits for patients with uncontrolled asthma despite the use of ICS and LABAs. Tiotropium is included in the Global Initiative for Asthma (GINA) strategy document as an add-on therapy option for patients at Step 4 or 5 with a history of asthma exacerbations. Tiotropium Respimat® has demonstrated safety and efficacy in patients with a range of disease severities, ages, and phenotypes. This review describes the evidence for the use of LAMA as add-on therapy for patients with asthma who remain uncontrolled despite the use of ICS and LABA treatments.

The prevention of and the controlling of symptoms, reductions in the frequency of exacerbations, and disease severity are central to the pharmacologic therapy of chronic obstructive pulmonary disease (COPD). COPD patients are inclined to be older, have more comorbidities, and use polypharmacy as a result. Long-acting inhaled muscarinic antagonists (LAMAs) is a preferred treatment modality. However, the cardiovascular (CV) safety of anti-cholinergics, including LAMA, has been an issue. In contrast, the results of the UPLIFT trial and a pooled analysis of data from 30 trials of tiotropium illustrates the association of tiotropium with reductions in the risk of all cause mortality, CV mortality and CV events. And, the UPLIFT trial provides clues regarding the additive advantages of tiotropium in COPD patients who already are using long-acting inhaled beta2 agonists and inhaled corticosteroids. Following the contribution of tiotropium as a first LAMA, new LAMAs such as aclidinium and glycopyrrolate (NVA-237) seem to be emerging.

OBJECTIVE: The study aimed to evaluate efficacy of tiotropium as add-on therapy on top of standard regimens for uncontrolled asthma, specifically in terms of FEV1, morning and evening PEF, reduction in exacerbations, rescue medication use, and quality of life improvement.
METHODS: A search was done for eligible trials after which validity screen and data extraction was performed. Results were presented as mean differences, standard errors, and 95% confidence intervals, and graphically as forest plots. Estimates were pooled using the random effects model with I2 and Chi2 tests used to assess heterogeneity. Adverse events were reported as dichotomous variables.
RESULTS: Four studies were included totaling 1617 participants. The tiotropium group had statistically significant improvement in FEV1 (95% Cl, 0.14 [0.09, 0.19], p<0.00001), morning (95% Cl, 20.03 [11.71, 28.35], p<0.00001) with trend towards benefit in reduction of rescue medications (95% Cl, 0.12 [-0.17,0.4],p=0.42) and quality of life improvements (95% Cl, 0.1 [-0.05,0.25], p=0.20). Homogeneity (I2= 0%, Chi2= 0.47-3.22) was found across studies.
CONCLUSION: Tiotropium is associated with significant improvement in pulmonary function among patients with uncontrolled asthma, with possible benefit in reduction of rescue medications and quality of life improvement.

Bronchodilator therapy is central to the management of chronic obstructive pulmonary disease and are recommended as the preferred treatment by the Global Obstructive Lung Disease Initiative (GOLD). Long acting anti-muscarinics (LAMA) and long acting β₂ agonists (LABA) are both more effective than regular short-acting drugs but many patients remain symptomatic despite monotherapy with these drugs. Combination therapy with LAMA and LABA increases the therapeutic benefit while minimizing dose-dependent side effects of long-acting bronchodilator therapy. The TOviTO programme has investigated the benefits of treatment with a combination of tiotropium and olodaterol administered via a single inhaler. Tiotropium+olodaterol 5/5 µg significantly improved forced expiratory volume in 1 second (FEV₁) area under the curve from 0 to 3 hours, trough FEV₁ health status and breathlessness versus the mono-components and placebo. Tiotropium+olodaterol 5/5 µg also increased endurance time and reduced dynamic hyperinflation during constant work rate cycle ergometry. On the basis of these and other studies the 2017 GOLD report recommends escalating to dual bronchodilator therapy in patients in groups B and C if they remain symptomatic or continue to have exacerbations and as initial therapy for patients in group D.

Asthma, remains symptomatic despite ongoing treatment with high doses of inhaled corticosteroids (ICS) in conjunction with long-acting beta-agonists (LABA), is classified as “severe” asthma. In the course of caring for those patients diagnosed with severe asthma, stepping up from ICS/LABA to more aggressive therapeutic measures would be justified, though several aspects have to be checked in advance (including inhaler technique, adherence to therapy, and possible associated comorbidities). That accomplished, it would be advisable to step up care in accordance with the Global Initiative for Asthma (GINA) recommendations. Possible strategies include the addition of a leukotriene receptor antagonist or tiotropium (to the treatment regimen). The latter has been shown to be effective in the management of several subgroups of asthma. Oral corticosteroids have commonly been used for the treatment of patients with severe asthma in the past; however, the use of oral corticosteroids is commonly associated with corticosteroid-related adverse events and comorbidities. Therefore, according to GINA 2017 these patients should be referred to experts who specialize in the treatment of severe asthma to check further therapeutic options including biologics before starting treatment with oral corticosteroids.
