Abstract: The invention relates to methods of identifying a composition useful for the prevention or treatment of noise-induced hearing loss. The method includes exposing a mammalian test subject to a candidate composition and a calibrated sound or noise challenge. Next, a temporary threshold shift (TTS) is monitored in the test subject over a period of time. The monitored TTS is compared with a TTS of a control subject exposed to a control composition. The presence or absence is determined by clinically relevant and statistically significant differences between the monitored TTS in the test subject and the TTS of the control subject, and the presence of a statistically significant difference identifies the candidate composition as useful for prevention or treatment of noise-induced hearing loss.

Abstract: Disclosed herein are novel drug combinations comprising a glutathione peroxidase (GPx) mimic compound and an antipsychotic agent, pharmaceutical compositions comprising one or more of such combinations, methods of preparing pharmaceutical compositions comprising one or more such combinations, and methods of treatment, prevention, inhibition or amelioration of one or more diseases associated with GPx mediated disorders, psychotic disorders or complications from administering an antipsychotic agent at high dose or long term using such combination or pharmaceutical compositions. Furthermore, a method is disclosed for reducing the anti-psychotic agent's dosages that comprises co-administering a therapeutically effective amount of a glutathione peroxidase mimic compound.
