Further study details as provided by Phafag AG:

Primary Outcome Measures:
  • to investigate the efficacy of Caroverin in transtympanic treatment of patients with tinnitus measured by a visual analogue scale. [ Time Frame: treatment takes 5 days, follow up examination 4 weeks after ]

Secondary Outcome Measures:
  • to investigate the time from the start of treatment to an improvement in tinnitus [ Time Frame: treatment takes 5 days, follow up examination 4 weeks after ]
  • to investigate the efficacy of Caroverin depending the origin of tinnitus [ Time Frame: treatment takes 5 days, follow up examination 4 weeks after ]
  • to investigate the safety of Caroverin treatment [ Time Frame: treatment takes 5 days, follow up examination 4 weeks after ]
  • to investigate the impact of Caroverin treatment of quality of life [ Time Frame: treatment takes 5 days, follow up examination 4 weeks after ]

  • Patients who have previously had a fracture of the petrous bone
  • Subjects suffering from acute or chronic accompanying conditions which severely impede their general health (NYHA stage IV, cancer, HIV etc.)
  • Accompanying conditions that according to the current state of scientific knowledge could affect the parameters used in this study to such an extent as to make it impossible to perform an objective assessment of those parameters, particularly ear conditions, including any conditions affecting the other ear or conditions like HI NYHA stage IV, cancer, HIV, Wallenberg Syndrome, massive Hypotension, Glaucoma.)
  • Accompanying medication that according to the current state of scientific knowledge are likely to affect the measurement techniques used in this study or the results obtained (cytostatics, aminoglycoside antibiotics, loop diuretics (furosemide, etacrynic acid), psycho pharmaceuticals, muscle relaxants, benzodiazepines, salicylates, quinine, cortisone and/or caroverine within the three days preceding the start of the study)
  • Drug treatment for tinnitus or sudden hearing loss (i.v. and oral) within seven days preceding the start of the study where the total duration of the course is less than four weeks
  • Diseases or conditions that may be associated with an altered perception or processing of stimuli, e.g. mental illness
