Ototoxicity Research

Ototoxicity Research

The ear is the only major organ that is not included on the FDA’s list of recommended tissues to test for toxicity as part of regulatory submission. Since approximately one-third of all FDA approved drugs are associated with hearing loss or tinnitus as possible side effects, the potential for ototoxicity is both well-documented and not adequately addressed.  As part of an exclusive partnership with Turner Scientific, Sinclair Research believes that the potential for ototoxicity is not being adequately addressed and that evaluating such potential damage to hearing represents a large unmet need both patients and drug developers.

Built on more than 50 years of experience, Sinclair Research offers Ototoxicity research services to support biopharmaceutical, animal health and medical device development programs. Sinclair offers unparalleled expertise in all research models and is a pioneer in miniature swine research.

Through our partnership with Turner Scientific, an established leader in Ototoxicity, Sinclair offers GLP auditory safety testing to evaluate detect and define potential ototoxicity of any drug or chemical to cause damage to the ears. In addition, Sinclair Research now offers testing to evaluate efficacy of drugs in improving hearing and preventing hearing loss, reducing the risks and severity of tinnitus, and improving vestibular dysfunction.

  • Additional antibiotics such as erythromycin, vancomycin, and many others
  • Diuretics such as furosemide, bumetanide
  • Chemotherapeutic (cancer) agents such as bleomycine, cisplatin, carboplatinum, methotrexate
  • Antimalarials such as chloroquine
  • Cardiac medications such as propanolol, quinidine
  • Anesthetics such as lidocaine, bupivacain
  • Psychopharmacologic agents such as amitryptiline, benzodiazepines, bupropion, fluoxetine, imipramine, lithium
