  Purpose

This is a double blind, controlled clinical trail testing whether three doses of 1.25 mg of nebulized levalbuterol in combination with three doses of 0.5mg of nebulized ipratropium will lead to greater bronchodilation than that achieved by three doses of nebulized 1.25 mg of levalbuterol alone every 20 minutes.

The primary hypothesis of this study is that three doses of 1.25 mg of nebulized levalbuterol in combination with three doses of 0.5mg of nebulized ipratropium will lead to greater bronchodilation than that achieved by three doses of nebulized 1.25 mg of levalbuterol alone every 20 minutes. The secondary hypothesis is that the treatment combination of levalbuterol and ipratropium will lead to fewer hospitalizations than levalbuterol alone in patients with acute asthma exacerbation. Other secondary objectives include (1) evaluating the relationship between baseline (S)- albuterol levels and (R)- albuterol levels on presentation and FEV1, (2) the relationship between baseline (S)- albuterol levels and (R)- albuterol levels on presentation and change in FEV1,(3) time to event analysis for an improvement of 15%, 20%, 30%, 40%, and 50% in FEV1 from initial presentation value, (4) analysis of FEV1 at discharge.

Primary Outcome Measures:
  • To determine if 1.25mg nebulized levalbuterol + 0.5mg nebulized ipratropium administered every 20 minutes for a total of 3 doses provides greater bronchodilation than 1.25mg nebulized levalbuterol administered every 20 minutes for a total of 3 doses. [ Time Frame: Pre-tx & 60 min. post 3rd tx FEV1 ] [ Designated as safety issue: No ]

Enrollment: 142

Study Completion Date: December 2008
Primary Completion Date: November 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
levalbuterol 1.25 mg every 20 minutes for 3 doses plus placebo (saline)
Drug: ipratropium
0.5 mg of ipratropium added to 1.25 mg levalbuterol given every 20 minutes for 3 doses
Experimental: 2
ipratropium 0.5 mg nebulized every 20 minutes for 3 doses added to levalbuterol 1.25 mg every 20 minutes for 3 doses
Drug: ipratropium
0.5 mg of ipratropium added to 1.25 mg levalbuterol given every 20 minutes for 3 doses

Detailed Description:

Patients will then receive, in a randomized double-blinded fashion, levalbuterol, 1.25mg every 20 minutes for a total of 3 aerosolized doses combined with ipratropium, 0.5mg every 20 minutes for a total of 3 aerosolized doses. The medication will be premixed by the pharmacy in a total of 3 ml of normal saline and the nebulizer will be driven with oxygen at 6 liters per minute. A second plasma sample for analysis of albuterol isomers will be drawn within a fifteen minute window following the third aerosol treatment. Spirometry will be repeated again at 30 and 60 minutes after the third aerosol treatment (Figure 1). All patients will receive prednisone, 60mg orally immediately after their first dose of aerosolized medications, unless contraindications to prednisone administration are present. Patients will not receive any other medications during the time course of the study. Vital signs and pulse oximetry will be repeated prior to each nebulized treatment and again 30 minutes after the third nebulized treatment.

The study will terminate 60 minutes after the third aerosol administration. At that point, any further therapy will be at the discretion of the treating physician. Patients will be questioned about the occurrence of any side effects from levalbuterol treatment including palpitations, anxiety, nausea, vomiting or headache. Patients will also be questioned about the occurrence of any side effects from ipratropium, including dry mouth, dry eyes, and urinary retention. Patients will be withdrawn from the study at any point these side effects become intolerable to the patient or any time the patient so desires. Patients will also be withdrawn if they develop palpitations and have an ECG that demonstrates ventricular or supraventricular tachycardia.

.Patients will be called 14 days after their ED visit to assess relapse or recurrence of acute asthma exacerbation. In addition, a chart review will be performed to assess relapse or recurrence of acute asthma exacerbation, as well as determine hospital length of stay in those patients who required admission after the initial visit.
