Stumbled across this study. Interesting they specifically mention sensorineural tinnitus. It appears to be an MAO-I.
Saw that lol. But I would NOT put it past the tinnitus research community to have cured this thing 30 years ago and have it sitting on a shelf somewhere in Japan. It may sound a little harsh saying so, but so is my tinnitus ¯\_(ツ)_/¯
