||The ability of drugs to reduce noise induced hearing loss (NIHL) has been evaluated in diverse experimental conditions (animal species, noise intensities, durations, assessment techniques, etc.), making it difficult to assess their relative efficacy. The present study was designed to provide more uniform comparisons and to allow a better understanding of the mechanism of the NIHL. The drugs studied included furosemide and the antioxidants N-acetyl-L-cysteine, vitamins A, C, E with the vasodilator magnesium. Mice were exposed to a continuous broadband noise (113 dB SPL for 3.5 hours) and the NIHL was assessed in all animals before noise exposure and 1 week after with auditory nerve brainstem evoked responses (ABR) to broadband clicks and to 8 kHz tone bursts. Each of the drugs alone and in combination led to similar reductions in NIHL.
