Efficacy and safety of ipratropium bromide/albuterol compared with albuterol in patients with moderate-to-severe asthma: a randomized controlled trial.

Background: Many patients with asthma require frequent rescue medication for acute symptoms despite appropriate controller therapies. Thus, determining the most effective relief regimen is important in the management of more severe asthma. This study's objective was to evaluate whether ipratropium bromide/albuterol metered-dose inhaler (CVT-MDI) provides more effective acute relief of bronchospasm in moderate-to-severe asthma than albuterol hydrofluoroalkaline (ALB-HFA) alone after 4 weeks.

COPD patient satisfaction with ipratropium bromide/albuterol delivered via Respimat: a randomized, controlled study.

Background: Ipratropium bromide/albuterol Respimat inhaler (CVT-R) was developed as an environmentally friendly alternative to ipratropium bromide/albuterol metered-dose inhaler (CVT-MDI), which uses a chlorofluorocarbon propellant.

Objective: The objective of this study was to evaluate patient satisfaction, device usage, and long-term safety of CVT-R compared to CVT-MDI, and to the simultaneous administration of ipratropium bromide hydrofluoroalkane (HFA; I) and albuterol HFA (A) metered-dose inhalers as dual monotherapies (I + A).

Design: This is a 48-week, open-label, randomized, active-controlled, parallel-group study (n = 470) comparing CVT-R to CVT-MDI and to I + A.

Development and validation of a cough and sputum assessment questionnaire.

Although cough and sputum production may impact patients' well being and functioning in COPD and chronic bronchitis, there is no validated instrument for cough and sputum symptoms and their impact on patients' daily activities. To fill that gap, we developed and validated a specific, multilingual Cough and Sputum Assessment Questionnaire (CASA-Q) that evaluates clinical symptoms and their impact on patients with COPD or chronic bronchitis. In a three-country validation study (n=671), there was adequate internal consistency (Cronbach's alphas, 0.

One-Year Evaluation of the Safety and Efficacy of Ipratropium Bromide HFA and CFC Inhalation Aerosols in Patients with Chronic Obstructive Pulmonary Disease.

Introduction: Ipratropium bromide (IB) is an established and effective first-line maintenance treatment for patients with chronic obstructive pulmonary disease (COPD). A new IB metered-dose inhaler (MDI) using hydrofluoroalkane 134a propellant (IB HFA) has been developed as an alternative to the MDI containing chlorofluorocarbon (IB CFC).

Objective: To compare the long-term safety and efficacy of IB HFA and IB CFC in patients with COPD.
