Inhaler devices for patients with COPD.

Chronic obstructive pulmonary disease (COPD) continues to be associated with increased morbidity and mortality risk in spite of updated guidelines and a better understanding of this condition. Progressive airflow limitation and resultant hyperinflation-the respiratory hallmarks of this complex and often under-diagnosed disease-can be treated with pharmacotherapies emitted via nebulizers, pressurized metered-dose inhalers, dry powder inhalers, or a Soft Mist inhaler. Pharmaceutical company proprietary issues, technological innovations, and societal pressure have expanded the list of available inhalers, with a limited range of medications available for any one device.

Practical aspects of inhaler use in the management of chronic obstructive pulmonary disease in the primary care setting.

Sustained bronchodilation using inhaled medications in moderate to severe chronic obstructive pulmonary disease (COPD) grades 2 and 3 (Global Initiative for Chronic Obstructive Lung Disease guidelines) has been shown to have clinical benefits on long-term symptom control and quality of life, with possible additional benefits on disease progression and longevity. Aggressive diagnosis and treatment of symptomatic COPD is an integral and pivotal part of COPD management, which usually begins with primary care physicians. The current standard of care involves the use of one or more inhaled bronchodilators, and depending on COPD severity and phenotype, inhaled corticosteroids.

Critical care in the ED: potentially fatal asthma and acute lung injury syndrome.

Emergency department clinicians are frequently called upon to assess, diagnose, and stabilize patients who present with acute respiratory failure. This review describes a rapid initial approach to acute respiratory failure in adults, illustrated by two common examples: (1) an airway disease - acute potentially fatal asthma, and (2) a pulmonary parenchymal disease - acute lung injury/acute respiratory distress syndrome. As such patients are usually admitted to hospital, discussion will be focused on those initial management aspects most relevant to the emergency department clinician.

Lack of paradoxical bronchoconstriction after administration of tiotropium via Respimat® Soft Mist™ Inhaler in COPD.

Bronchoconstriction has been reported in asthma and chronic obstructive pulmonary disease (COPD) patients after administration of some aqueous inhalation solutions. We investigated the incidence of this event during long-term clinical trials of tiotropium delivered via Respimat(®) Soft Mist™ Inhaler (SMI). We retrospectively analyzed pooled data from two identical Phase III clinical trials, in which 1990 patients with COPD received 48 weeks' treatment with once-daily tiotropium (5 or 10 μg) or placebo inhaled via Respimat(®) SMI.

Efficacy and safety of tiotropium Respimat SMI in COPD in two 1-year randomized studies.

Two 1-year studies evaluated the long-term efficacy and safety of tiotropium 5 or 10 microg versus placebo, inhaled via the Respimat Soft Mist Inhaler (SMI). The two studies were combined and had 4 co-primary endpoints (trough FEV(1) response, Mahler Transition Dyspnea Index [TDI] and St George's Respiratory Questionnaire scores all at week 48, and COPD exacerbations per patient-year). A total of 1990 patients with COPD participated (mean FEV(1): 1.

The MRC dyspnoea scale by telephone interview to monitor health status in elderly COPD patients.

Dyspnoea is the most common symptom associated with poor quality of life in patients affected by Chronic Obstructive Pulmonary Disease (COPD). While COPD severity is commonly staged by lung function, the Medical Research Council (MRC) dyspnoea scale has been proposed as a more clinically meaningful method of quantifying disease severity in COPD. We wished to assess whether this scale might also be useful during telephone surveys as a simple surrogate marker of perceived health status in elderly patients with COPD.

Asthma patients prefer Respimat Soft Mist Inhaler to Turbuhaler.

Device satisfaction and preference are important patient-reported outcomes to consider when choosing inhaled therapy. A subset of adults (n = 153) with moderate or severe asthma participating in a randomized parallel-group, double-dummy trial that compared the efficacy and safety of 12 weeks' treatment with budesonide delivered via Respimat Soft Mist Inhaler (SMI) (200 or 400 microg bd) or Turbuhaler dry powder inhaler (400 microg bd), completed a questionnaire on patient device preference and satisfaction (PASAPQ) as part of a psychometric validation. As the study used a double-dummy design to maintain blinding, patients used and assessed both devices, rating their satisfaction with, preference for, and willingness to continue using each device.

Living with chronic obstructive pulmonary disease: a survey of patients' knowledge and attitudes.

Introduction: Chronic obstructive pulmonary disease (COPD) is a common respiratory condition and the fourth leading cause of death in Canada. However, little is known about the impact of COPD on the lives and attitudes of individuals living with this condition. The purpose of this study was to determine whether Canadians with COPD are properly educated and supported, and to recommend solutions to any care gaps identified.

Canadian Thoracic Society recommendations for management of chronic obstructive pulmonary disease - 2007 update.

Chronic obstructive pulmonary disease (COPD) is a major respiratory illness in Canada that is both preventable and treatable. Our understanding of the pathophysiology of this complex condition continues to grow and our ability to offer effective treatment to those who suffer from it has improved considerably. The purpose of the present educational initiative of the Canadian Thoracic Society (CTS) is to provide up to date information on new developments in the field so that patients with this condition will receive optimal care that is firmly based on scientific evidence.

The paradox of adult asthma control: "who's in control anyway?".

Surveys of Canadian patients with asthma and their physicians consistently report satisfaction with asthma management; however, when objective indicators are used, these same surveys also observe very poor levels of asthma control. The reasons for this apparent discrepancy, with an emphasis on the factors influencing adherence to therapy, are explored in the present review. Clues to the identification of patients at risk of dying from asthma and an approach to difficult asthma are discussed.

Burden of illness in venous thromboembolism in critical care: a multicenter observational study.

Purpose: The frequency of clinically diagnosed venous thromboembolism (VTE) including deep venous thrombosis (DVT) and pulmonary embolism (PE) in medical-surgical critically ill patients is unclear. The objectives of this study were to estimate the prevalence and incidence of radiologically confirmed DVT and PE in medical-surgical intensive care unit (ICU) patients and to determine the impact of prophylaxis on the frequency of these events.

Materials And Methods: In a retrospective observational cohort study in 12 adult ICUs, we identified prevalent cases (diagnosed in the 24 hours preceding ICU admission up to 48 hours post-ICU admission) and incident cases (diagnosed 48 hours or more after ICU admission and up to 8 weeks after ICU discharge) of upper or lower limb DVT or PE.

Low incidence of paradoxical bronchoconstriction in asthma and COPD patients during chronic use of Respimat soft mist inhaler.

Respimat Soft Mist Inhaler (SMI) is a new-generation inhaler that offers improved lung deposition compared with chlorofluorocarbon metered dose inhalers (CFC-MDIs). Bronchodilators administered via Respimat SMI are preserved and stabilised with low concentrations of benzalkonium chloride and ethylene diamine tetra-acetic acid, both of which have been reported to cause dose-related paradoxical bronchoconstriction. The aim of this analysis was to compare the incidence of paradoxical bronchoconstriction after chronic use of bronchodilators via Respimat SMI and CFC-MDI.

State of the Art Compendium: Canadian Thoracic Society recommendations for the management of chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a common cause of disability and death in Canada. Moreover, morbidity and mortality from COPD continue to rise, and the economic burden is enormous. The main goal of the Canadian Thoracic Society's evidence-based guidelines is to optimize early diagnosis, prevention and management of COPD in Canada.

A review of ipratropium bromide/fenoterol hydrobromide (Berodual) delivered via Respimat Soft Mist Inhaler in patients with asthma and chronic obstructive pulmonary disease.

Asthma and chronic obstructive pulmonary disease (COPD) can be effectively treated by the use of bronchodilator therapies delivered by inhalation. Berodual is a fixed combination of the anticholinergic agent ipratropium bromide (IB) and the beta2-adrenergic agonist fenoterol hydrobromide (FEN). IB/FEN has been available for the treatment of asthma and COPD in a pressurised metered dose inhaler (MDI) [pMDI] formulation for many years.
