Clinical Trial Summary

Objective To observe the safety and tolerability of Pazufloxacin Mesylate Ear Drops of different concentrations in patients with simple chronic suppurative otitis media.

Description:

The test group was completed in sequence from low to high concentrations, and safety tolerance was assessed after administration in one concentration group to determine whether to conduct follow-up group studies and, if necessary, adjust sampling time points according to pre-experimental results.
