Summary
ABSTRACT CONTEXT: Inappropriate antibiotic prescriptions for acute bronchitis is a major
public health concern because of antibiotic resistance. Effective therapies for managing the
symptoms of acute bronchitis are lacking, however.
OBJECTIVE: Determine if patients with acute bronchitis have better symptom control when
treated with inhaled ipratropium.
DESIGN, SETTING, PARTICIPANTS: COUGH STOP was a randomized, double blind, placebo controlled
trial comparing ipratropium with placebo in acute bronchitis. Subjects were referred by their
primary care provider or from urgent care clinics at a single institution. Subjects had been
diagnosed with acute bronchitis and had no significant co-morbidities.
INTERVENTION: Subjects received ipratropium or placebo inhalers, administering 2 puffs four
times daily. A structured telephone interview took place 2, 4, and 8 days after enrollment.
Medical records were reviewed at 60 days.
OUTCOME: The primary endpoint was improvement in cough symptomology; secondary endpoints
included subsequent antibiotic prescriptions and "well being."
