Primary Outcome Measures:
  • Area Under the Curve from 0 to 24 hours (AUC0-24h)
  • Elimination half-life (t1/2)
  • Maximum Concentration (Cmax)
  • Concentration 24 hours after instillation (C24h)

Secondary Outcome Measures:
  • Tolerance

Study Start Date: May 2002
Estimated Study Completion Date: June 2002
Detailed Description:
The aim of the present study was to compare azithromycin tear ocular concentrations after a single instillation of three different T1225 concentrations in order to determine early azithromycin tear concentration and to assess the T1225 concentration, which allowed having the higher azithromycin tear concentration, 24 hours after a single instillation.
