Pneumonia
Conditions
Brief summary
The intravenous (IV) regimen containing azithromycin (Zithromax) plus ampicillin-sulbactam is consistent with current guidelines for the treatment of CAP. In fact the International guidelines for the treatment of CAP in hospitalised patients suggests the use of a combination between a b-lactam and a macrolide. This trial will allow investigators to evaluate the efficacy of azithromycin plus ampicillin-sulbactam in the treatment of hospitalized subjects with community acquired pneumonia. In addition, this trial will allow investigators to evaluate the safety and toleration of combination therapy.

The following criteria must be met: * new infiltrate(s) on chest X-ray; AND * at least two of the CAP signs or symptoms.
Exclusion criteria
