Nebulized formoterol provides added benefits to tiotropium treatment in chronic obstructive pulmonary disease.

Introduction: The use of one or more long-acting bronchodilators is key in the maintenance therapy of chronic obstructive pulmonary disease (COPD). This analysis pooled the results of two double-blind studies evaluating the efficacy and safety of adding nebulized formoterol fumarate inhalation solution (FFIS) to maintenance tiotropium (TIO) treatment.

Methods: Following a run-in period of 7-14 days with once-daily TIO 18 microg, COPD subjects (> or =25% to <65% predicted forced expiratory volume in 1 second [FEV(1)]) were randomized to twice-daily FFIS 20 microg (n=145) or nebulized placebo (PLA, n=140) while continuing on maintenance TIO for 6 weeks.

Efficacy and safety of nebulized formoterol as add-on therapy in COPD patients receiving maintenance tiotropium bromide: Results from a 6-week, randomized, placebo-controlled, clinical trial.

Current guidelines for the treatment of chronic obstructive pulmonary disease (COPD) recommend the use of long-acting bronchodilators in the maintenance management of COPD. Combining bronchodilators that work through different mechanisms is recommended in patients with continuous symptoms. We conducted this study to confirm and further investigate the efficacy and safety of nebulized formoterol as an add-on therapy to maintenance tiotropium in patients with COPD.

Nebulized formoterol effect on bronchodilation and satisfaction in COPD patients compared to QID ipratropium/albuterol MDI.

Objective: Bronchodilator maintenance treatment improves pulmonary function and health-related quality of life in COPD patients. Pulmonary function and patient preference/satisfaction were compared before and after treatment with a short-acting ipratropium/albuterol combination and long-acting nebulized formoterol.

Methods: A randomized, open-label, crossover trial was conducted at 16 centers in the US.

Long-term safety of nebulized formoterol: results of a twelve-month open-label clinical trial.

Unlabelled: Formoterol fumarate is a long-acting beta2-agonist that is an effective bronchodilator for the maintenance management of patients with chronic obstructive pulmonary disease. The safety profile of the newly developed nebulized formoterol was evaluated over a twelve-month period in an open-label, active-control study. After completing a twelve-week double-blind double-dummy period, 569 subjects with chronic obstructive pulmonary disease entered an open-label extension study and received twice-daily 20 microg formoterol fumarate inhalation solution for nebulization (FFIS) or 12 microg formoterol fumarate dry powder inhalation (FA) for 52 weeks.

Nebulized formoterol fumarate: Dose selection and pharmacokinetics.

To determine a dose of nebulized formoterol fumarate inhalation solution (FFIS) comparable to that of the marketed formoterol fumarate dry powder inhaler (FA, 12microg), two crossover studies were conducted in subjects with COPD. Study 1 was a single-dose, double-blind, double-dummy dose-ranging study in which 47 subjects were randomly assigned to treatment sequences that evaluated the bronchodilatory effects of FFIS 2.5, 5, 10, 20, and 40microg, FA, and placebo over 12h.
