Brief Summary

The specific aim of the Gabapentin for the Relief of Idiopathic Subjective Tinnitus Trial is to assess the therapeutic benefit of Gabapentin (Neurontin®) for subjective idiopathic troublesome tinnitus. We employed a double-blind placebo-controlled randomized clinical trial design to assess the efficacy of Gabapentin. Adults, between the ages of 18 and 70 with idiopathic, subjective, troublesome, unilateral or bilateral, non-pulsatile tinnitus of 6 month's duration or greater and score of 38 or greater on the Tinnitus Handicap Inventory were enrolled.

Eligibility Criteria

Age18 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults, between the ages of 18 and 70
  • Idiopathic, subjective, troublesome, unilateral or bilateral, non-pulsatile tinnitus (ICD-9 --388.31) of 6 month's duration or greater
  • Tinnitus handicap score of 38 or greater on the Tinnitus Handicap Inventory.

You may not qualify if:

  • Impaired renal function as determined from serum creatinine levels, using the following formulas35: adult male Ccr = (140 -age) X weight in kilograms/(72 X serum creatinine in milligrams per deciliter); and adult female Ccr = \[(140 - age) X weight in kilograms/(72 X serum creatinine in milligrams per deciliter)\] X 0.85,whereCcr indicates creatinine clearance.
  • Patients with tinnitus related to cochlear implantation, retrocochlear lesion, or other known anatomic/structural lesions of the ear and temporal bone
  • Patients with any serious or unstable medical or psychiatric condition.
