Primary Outcome Measures:

Bacteriologic response (eradication or persistence) at the Test of Cure (TOC) visit in the Bacteriologic Per Protocol population [ Time Frame: TOC visit (Day 24-28) ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Bacteriologic eradication rate at the Long-Term Follow-Up (LTFU) visit [ Time Frame: LTFU Visit (Day 38-45) ] [ Designated as safety issue: No ]
Clinical response (clinical cure or failure) at the TOC visit in the Bacteriologic Per Protocol population [ Time Frame: TOC Visit (Day 24-28) ] [ Designated as safety issue: No ]
Clinical response (cure or relapse) at the LTFU visit [ Time Frame: LTFU Visit (Day 38-45) ] [ Designated as safety issue: No ]
Pathogen susceptibility versus bacteriologic response [ Time Frame: Not reported ] [ Designated as safety issue: No ]
Adverse events (AEs) were assessed for all treated subjects [ Time Frame: Continuous ] [ Designated as safety issue: Yes ]
Vital signs and physical examinations were recorded [ Time Frame: Baseline and as necessary ] [ Designated as safety issue: Yes ]
Clinical laboratory testing (hematology and blood chemistry) [ Time Frame: As necessary ] [ Designated as safety issue: Yes ]
Azithromycin serum concentrations were determined for patients who vomited within 30 minutes of receiving their azithromycin SR/placebo dose [ Time Frame: Day 1 ] [ Designated as safety issue: Yes ]

Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Patients who had evidence of acute pharyngitis/tonsillitis based on erythematous pharyngeal mucosa or thick exudate covering the pharynx and tonsillar area, and at least one of the following signs or symptoms were included: sore/scratchy throat; pain on swallowing; chills and/or fever cervical adenopathy; scarlet fever rash on the face and skin folds, or red tongue with prominent papillae ("strawberry tongue").
