  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).

Condition Intervention Phase
Pharmacokinetics Drug: azithromycin immediate release (Zithromax) Other: placebo Drug: azithromycin SR Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: A Randomized, Open Label, Clinical Trial of the Pharmacokinetics of Azithromycin in Serum, Bronchial Washings and Lung Tissue Following a Single Dose of Azithromycin Sustained Release (2 Gram) or Commercial Azithromycin Tablet (500 mg) to Cancer Patients That Require Lung Resection
