Brief Summary:
The major objectives of this research are to see how much, and for how long, telithromycin and azithromycin get into the fluids and cells of the lung.

Condition or disease Intervention/treatment Phase
Healthy Drug: Telithromycin Drug: azithromycin Procedure: bronchoalveolar lavage Phase 4

Detailed Description:
The primary objective of this descriptive study is to determine and compare the plasma, epithelial lining fluid (ELF), and alveolar macrophage (AM) concentrations following multiple oral doses of telithromycin and azithromycin in healthy, non-smoking adult subjects.
