  Purpose
The objectives of the study were to confirm that a single, 2.0-g dose of azithromycin sustained release (SR) was at least as effective to 10 days of oral levofloxacin 500 mg once a day, when used to treat adults with uncomplicated, acute bacterial sinus infections, and to evaluate the safety of both treatments.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Multicenter, Randomized, Double-Blind, Double-Dummy Comparative Trial of Azithromycin SR Versus Levofloxacin for the Treatment of Acute Bacterial Maxillary Sinusitis in Adults Undergoing Diagnostic Sinus Aspiration

Criteria

Inclusion Criteria:

Patients were included if they had a clinical diagnosis of acute bacterial maxillary sinusitis as demonstrated by presence of the cardinal signs and symptoms for a minimum duration of 7 days, a sinus X-ray (Water's view) confirming the clinical diagnosis of maxillary sinusitis, and 2 or more of following: fever, leukocytosis, frequent coughing, headache, nasal congestion, or post-nasal drainage.
