Zonisamide and Methylprednisolone Noise-Induced Hearing Loss Prevention Study

Withdrawn academic Phase 1/2 prevention study comparing oral zonisamide, methylprednisolone, and no medication around temporary noise exposure.

ClinicalTrials.gov verifies a withdrawn Washington University Phase 1/2 prevention study. The record was generated from one intervention arm, but the source trial included both zonisamide and methylprednisolone comparators; it should be read as a study-level historical record, not a standalone zonisamide program.
