  • Previous ASNHL incident within the past 6 weeks
  • Evidence of acute or chronic otitis media or otitis externa on examination
  • Any drug-based therapy for inner ear hearing loss that is ongoing or was performed in the past 2 weeks
  • Any ongoing or planned concomitant medication for the treatment of tinnitus until 30 days after administration
  • Any therapy known as ototoxic (e.g. aminoglycosides, cisplatin, loop diuretics, quinine etc.) in the past 6 months prior to study inclusion
  • History of drug abuse or alcoholism
  • Any clinically relevant respiratory, cardiovascular, neurological (except vertigo or tinnitus), or psychiatric disorders
  • Known hypersensitivity, allergy or intolerance to the study medication or any history of severe abnormal drug reaction
  • Women who are breast-feeding, pregnant or who plan a pregnancy during the trial
  • Women of childbearing potential who declare being unwilling or unable to practice contraception such as combined oral contraceptives, injectables, hormonal intra-uterine devices, vasectomised partner or sexual abstinence
  • Concurrent participation in another clinical trial or participation in another clinical trial within 30 days prior to study entry
  • Any current anticoagulant therapy (e.g. Aspirin, Marcumar, etc)
