Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Pharmacokinetics

Intervention: azithromycin immediate release (Zithromax) (Drug); placebo (Other); azithromycin SR (Drug)

Phase: Phase 2

Status: Completed

Sponsored by: Pfizer

Official(s) and/or principal investigator(s):

Summary

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).
