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.

Primary Purpose: Treatment
Official Title: A Multicenter, Open Label Trial Evaluating Intravenous Azithromycin Plus Intravenous Ampicillin/Sulbactam Followed by Oral Azithromycin Plus Intravenous Ampicillin/Sulbactam for the Treatment of Hospitalized Subjects With Community-Acquired Pneumonia (CAP)
Study Start Date : November 2003
Actual Study Completion Date : September 2005

Primary Outcome Measures :
  1. To evaluate the clinical efficacy of intravenous (IV) azithromycin 500 mg once daily plus IV ampicillin/sulbactam 3 grams twice a day (BID) for 2 to 5 days
  2. followed by oral azithromycin 500 mg once daily plus IV ampicillin/sulbactam 3 grams.

Secondary Outcome Measures :
  1. To evaluate the eradication of baseline pathogens of IV azithromycin plus IV ampicillin/sulbactam followed by oral azithromycin plus IV ampicillin/sulbactam at Visit 3 and Visit 4
