Patients with clinical evidence of mild to moderate community-acquired pneumonia,
including cough productive of sputum and a diagnosis of pneumonia, were included.
Key exclusion criteria were treatment with any systemic antibiotic of greater than one
dose or one combination dose within the previous 7 days, previously diagnosed conditions
which tend to mimic or complicate the course and the evaluation of the evaluation process
(e.g., bronchiectasis, lung abscess or empyema, active tuberculosis, pulmonary malignancy,
cystic fibrosis, post-obstructive pneumonia), hospitalization in the previous 14 days or
infection acquired in the hospital, and residents of a long-term care facility.
