Gabapentin for the Treatment of Tinnitus
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.

Medical and Biotech [MESH] Definitions
Tinnitus
A nonspecific symptom of hearing disorder characterized by the sensation of buzzing, ringing, clicking, pulsations, and other noises in the ear. Objective tinnitus refers to noises generated from within the ear or adjacent structures that can be heard by other individuals. The term subjective tinnitus is used when the sound is audible only to the affected individual. Tinnitus may occur as a manifestation of COCHLEAR DISEASES; VESTIBULOCOCHLEAR NERVE DISEASES; INTRACRANIAL HYPERTENSION; CRANIOCEREBRAL TRAUMA; and other conditions.
Endolymphatic Hydrops
An accumulation of ENDOLYMPH in the inner ear (LABYRINTH) leading to buildup of pressure and distortion of intralabyrinthine structures, such as COCHLEA and SEMICIRCULAR CANALS. It is characterized by SENSORINEURAL HEARING LOSS; TINNITUS; and sometimes VERTIGO.
Meniere Disease
A disease of the inner ear (LABYRINTH) that is characterized by fluctuating SENSORINEURAL HEARING LOSS; TINNITUS; episodic VERTIGO; and aural fullness. It is the most common form of endolymphatic hydrops.
Vestibular Neuronitis
Idiopathic inflammation of the VESTIBULAR NERVE, characterized clinically by the acute or subacute onset of VERTIGO; NAUSEA; and imbalance. The COCHLEAR NERVE is typically spared and HEARING LOSS and TINNITUS do not usually occur. Symptoms usually resolve over a period of days to weeks. (Adams et al., Principles of Neurology, 6th ed, p304)
Glomus Tympanicum Tumor
A rare PARAGANGLIOMA involving the GLOMUS TYMPANICUM, a collection of chemoreceptor tissue adjacent to the TYMPANIC CAVITY. It can cause TINNITUS and conductive hearing loss (HEARING LOSS, CONDUCTIVE).
