A Randomized, Open Label, Clinical Trial of the Pharmacokinetics of Azithromycin Following a Single Dose of Azithromycin Sustained Release (2 Gram) or Commercial Azithromycin Tablet (500 mg) to Cancer Patients That Require Lung Surgery - Full Text View

Sponsored by:	Pfizer
Information provided by:	Pfizer
ClinicalTrials.gov Identifier:	NCT00644176

Purpose

The objective of this trial was to characterize the pharmacokinetics of the currently marketed azithromycin immediate release tablet formulation (AZ-IR) versus the azithromycin sustained release liquid formulation (AZ-SR) in lung tissue and bronchial washings, the latter consisting of the epithelial lining fluid (ELF) and cellular elements, mainly alveolar macrophages (AM).
