STUDY OBJECTIVE To compare the efficacy and safety of ipratropium bromide reformulated with the chlorofluorocarbon (CFC)-free propellant hydrofluoroalkane (HFA)-134a (ipratropium bromide HFA) to that of the marketed ipratropium bromide inhalation aerosol (containing CFC) in patients with COPD. DESIGN This was a randomized, double-blind, parallel-group, placebo-controlled, multicenter trial. T...

STUDY OBJECTIVE This study was conducted to determine whether the addition of inhaled ipratropium to inhaled beta-agonist therapy is effective in the treatment of adults with acute asthma exacerbation. METHODS Published reports of randomized, controlled trials assessing the use of ipratropium and beta-agonists in asthma were identified by a search of the MEDLINE, EMBASE, CINAHL, Biological Ab...

We studied the differential response to inhaled salbutamol and ipratropium of 29 asthmatic patients, 18 intrinsic, 11 extrinsic, using peak expiratory flow rate (PEFR), forced expiratory volume in one second (FEV1), and forced vital capacity (FVC). Thirty minutes after a theoretically maximally bronchodilating dose of salbutamol (400 microgram) or ipratropium (80 microgram), second doses freque...

Aim use of inhalational insulin was limited due to its high cost and its potential to produce respiratory adverse effects. So current study was designed to evaluate the acute effects of insulin on airway reactivity and protective effects of salbutamol and ipratropium against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pig. Material and methods: effec...

In thirteen patients with extrinsic asthma the effects of placebo, sodium cromoglycate, ipratropium bromide, and ipratropium bromide plus sodium cromoglycate were studied in a random double-blind fashion to assess their inhibitory action in exercise-induced asthma (EIA). Exercise testing consisted of steady state running on an inclined treadmill for up to eight minutes. In eight of the 13 patie...

The aim of this paper is to assess the health economic consequences of substituting ipratropium with the new, once-daily bronchodilator tiotropium in patients with a diagnosis of chronic obstructive pulmonary disease (COPD). This prospective cost-effectiveness analysis was performed alongside two 1-yr randomised, double-blind clinical trials in the Netherlands and Belgium. Patients had a diagno...

BACKGROUND/AIMS Ipratropium bromide, an anticholinergic agent widely used in obstructive lung disease, has previously been shown to trigger suicidal death of nucleated cells or apoptosis. Despite their lack of mitochondria and nuclei, key organelles in the execution of apoptosis, erythrocytes may similarly undergo suicidal cell death, which is characterized by cell shrinkage and by cell membran...

OBJECTIVE To systematically review recent evidence on the effectiveness of tiotropium versus placebo, ipratropium, and long-acting β(2) agonists on outcomes relevant to patients with stable COPD, including health-related quality of life, dyspnea, exacerbations and hospitalizations. METHODS Our inclusion criteria for trials were: ≥ 12 weeks; compared tiotropium to placebo, ipratropium, or long...

The propellant-free Combivent Respimat Soft Mist Inhaler (CVT-R) was developed to replace the chlorofluorocarbon-propelled Combivent metered-dose inhaler (CVT-MDI). This steady-state pharmacokinetic (PK) substudy evaluated drug lung-delivery efficiency, using data from two phase III safety and efficacy trials. PK parameters were obtained from well-controlled population PK analyses. Area under t...

INTRODUCTION Although the prevalence of chronic obstructive pulmonary disease (COPD) is similar between men and women, current evidence used to support bronchodilator therapy has been generated in therapeutic trials that have predominately enrolled male patients. Here, we determined whether there is any significant sex-related differences in FEV1 responses to ipratropium bromide. METHODS Data...
