Definitions
- the present invention relates to a drug for the treatment of tinnitus patients.
- Tinnitus is a typical disease of inner ear disorders as well as hearing loss. Tinnitus is "accepting sound in the absence of acoustic stimulation from the outside environment" or "abnormal auditory phenomenon in which some sound sensation occurs even though there is no sound source outside the body" Defined. Tinnitus can be caused by disturbances in all the auditory tracts from the outer ear to the central auditory tract, but is generally caused by inner ear deafness, and an increase in abnormal neural activity in the central auditory tract is caused by decreased input of auditory information due to cochlear disturbances. It is considered a pathological condition. For individual patients, tinnitus can be acceptable or it can cause anxiety, depression, insomnia, inability to work, or mental distress.
