Summary

The objectives of this study were to:

- Examine the tolerability of two formulations and two dose concentrations of epinastine.

- Select formulation(s) of epinastine for future studies by evaluating the individual

- Compare the preference of two formulations and two dose concentrations of epinastine

compared to azelastine following a single dose of each in a randomized, double-blind, two-cohort, three-period crossover design.
