iopathic subjective tinnitus: Is gabapentin effec-tive?” [1], which concluded that gabapentin was no more effective than a placebo in relieving tinnitus. The goal of this editorial and commentary is constructive: to provide to tinnitus patients and professionals involved with tin-nitus diagnosis and treatment (1) a protocol for patient When you look at the published figures for Gabapentin and tinnitus you find that between 0.1% and 1% of the people taking Gabapentin get tinnitus. Since there are 46,043,168 prescriptions filled in the US each year, that would work out to between 46,043 and 460,431 incidences of tinnitus each year–and that is a LOT of people. International Tinnitus Journal, Vol. 14, No. 1, 1–5 (2008) - Gabapentin and Tinnitus Relief This article is an editorial reply on the JAMA Network report above. Controlled clinical trials investigating the effects of gabapentin on tinnitus have produced inconsistent results, with some studies suggesting a placebo effect and others indicating improvement with gabapentin use. However, these studies utilized a single drug dose and did not include objective measures of tinnitus loudness. Tinnitus, or ringing in the ears, is a listed side effect of Neurontin . Interestingly enough, even though gabapentin can cause ringing in the ears, it is sometimes prescribed off-label for the treatment of it. Despite basic scientific evidence, a case report of success in treatment of tinnitus with gabapentin, and clinical similarities between tinnitus and neuropathic pain, we did not find that gabapentin was clinically efficacious for the treatment of tinnitus. Calcium channel modulation. Gabapentin is thought to function as a GABA-modulator and alpha-2-delta calcium channel antagonist – and modulation of calcium channels may be its primary mechanism in the treatment of select cases of tinnitus. Gabapentin is effective in reducing subjective and objective aspects of tinnitus in some individuals, with the best therapeutic response obtained in individuals with associated acoustic trauma. There have been numerous studies that examine the efficacy of Neurontin as a treatment of tinnitus. While there has been some consensus that it is no better than a placebo, a recent meta-study suggests that no firm conclusions can be drawn: Gabapentin. Gabapentin (Neurontin®) is widely used in the treatment of seizures, neuropathic pain and migraine (174–177). Because of its structural similarity to GABA, gabapentin was thought to bind to GABA receptors ; however, its mechanisms of action are not fully understood. As an inhibitory neurotransmitter acting on voltage-gated calcium channels, the role of gabapentin in the treatment of tinnitus remains unclear. Gabapentin, however, has been reported to significantly improve annoyance and loudness of tinnitus related to acoustic trauma. All participants received gabapentin in a graduated ascending-descending dose series extending over 20 weeks (peak dose of 2,400 mg/d). Results: There was a significant improvement in tinnitus annoyance for the trauma group ( P = .05). Purpose: The main aim of this study was to assess the effect of gabapentin on tinnitus via a systematic review. Method: An electronic search of literature as well as a hand search were conducted. Only double-blind randomized controlled trials (RCTs) that met all of the inclusion criteria were included in this review. The pharmacologic management of tinnitus with brain-acting effects (for example, amitriptyline, acamprosate, and gabapentin) and those with anti-inflammation/anti-oxidant effect (for example, intra-tympanic dexamethasone injection plus oral melatonin) appear to serve as the preferable effective treatments for tinnitus without specific or There is no evidence to show that gabapentin has a large positive effect in the treatment of tinnitus [2]. One study showed treatment with gabapentin led to an increase in tinnitus [3]. A different study showed no differences on the Tinnitus Handicap Inventory compared to placebo [4]. We found that gabapentin significantly decreased the VAS score in patients with tinnitus due to acoustic trauma. Moreover, gabapentin significantly increased the frequency of patients responding to treatment (≥30% decrease in VAS).
