Abstract Background: Refractory chronic cough causes substantial symptoms and quality-of-life impairment. Similarities between central reflex sensitisation in refractory chronic cough and neuropathic pain suggest that neuromodulators such as gabapentin might be effective for refractory chronic cough. Gabapentin and Pregabalin are “nerve ending medications” used in treatment for Sensory Neuropathic Cough (SNC) and SNTC. As pain and cough share the remarkably similar pathways, gabapentin, traditionally used in treatment of neuropathic pain, was recently used as a non-specifc antitussives for chronic idiopathic cough 15, 17, 19. Gabapentin has a similar lipophilic structure to the neurotransmitter gamma aminobutyric acid which notoriously performs central action 20. The treatment of refractory chronic cough with gabapentin is both effective and well tolerated. These positive effects suggest that central reflex sensitisation is a relevant mechanism in refractory chronic cough. Side effects of gabapentin include somnolence and dizziness. Conclusion: Recent additions in the treatment of chronic cough have been significant as they consider cough to have a unifying diagnosis of cough hypersensitivity with or without the presence of a neuropathic basis. PRINT PDF. For most people with neurogenic cough, 800 mg. of gabapentin is not quite enough to knock out the cough. If you are on gabapentin 800 mg. (with 10 mg of amitriptyline) with insufficient benefit and no ill effects, contact your physician and escalate to gabapentin 300 mg. QID (4x/day) if more is needed after that, perhaps escalate to gabapentin 400 mg. QID. This protocol is However, the clinical trials of gabapentin for chronic refractory cough had some defects: fewer participants, lower research quality and greater bias, compared with other trials of gabapentin for chronic pain and epilepsy. As pain and cough share the remarkably similar pathways, gabapentin, traditionally used in treatment of neu-ropathic pain, was recently used as a non-specifc antitussives for chronic idiopathic cough15,17,19. Gabapentin has a similar lipophilic structure to the neu-rotransmitter gamma aminobutyric acid which notoriously performs central action20. Indeed, there is a real unmet need for effective treatments in patients suffering from cough. 2 It has been suggested that chronic cough is a neuropathic disorder, 3 and gabapentin, a treatment for neuropathic pain, has recently shown evidence of efficacy. The evaluation of chronic cough should address the possibilities of asthma, gastroesophageal reflux disease, and postnasal drip and may require more specialized investigations.

Abstract Introduction Gabapentin, a neurotransmitter modulator, is thought to treat refractory cough associated with interstitial lung disease by improving cough hypersensitivity. Methods/design This is a single-center, prospective, randomized, double-blind, placebo-controlled trial. The trial will investigate the effect of a 10-week course of oral gabapentin 900 mg/day on refractory cough Abstract Cough is a common respiratory symptom that is considered to be chronic when it lasts more than eight weeks. When severe, chronic cough may significantly impact an individual's quality of life, and such patients are frequently referred for specialist evaluation. Current international guidelines provide algorithms for the management of chronic cough: in most cases, treatment of the Recent success in the treatment of chronic cough with agents used for treating neuropathic pain such as gabapentin and amitryptiline would also support this concept. Research into neuropathic cough may lead to the discovery of more effective antitussives. Keywords: Chronic cough, cough hypersensitivity syndrome, gastroesophageal reflux Introduction Nonpharmacologic Treatment of Chronic Cough Current CHEST guidelines recommend a trial of multimodality speech pathology therapy in patients with UCC. 2 This recommendation was based on positive Conclusion: In patients with chronic cough seen in a tertiary care esophageal clinic, low dose gabapentin improved symptoms in a majority of patients, regardless of the results of reflux testing. These results suggest a novel approach to the treatment of chronic cough and merit additional study in a prospective trial. In The Lancet, Nicole Ryan and colleagues1 report on a placebo-controlled, double-blind trial of the effects of gabapentin—a drug used for epilepsy and neuropathic pain—on quality of life, cough frequency, and cough severity in people with chronic cough. This report does more than address the effectiveness of this cough suppressant—it emphasises that refractory chronic cough is an As such, gabapentin is an effective and well-tolerated treatment in chronic cough, and several prospective case series and cohort studies support its efficacy. 21, 22 The effectiveness of neuromodulating medications such as gabapentin and pregabalin in the treatment of cough has been supported primarily through case series, case reports, prospective reviews and a double blind randomised controlled trial. Gabapentin results in a reduction in cough frequency and cough severity. It improves cough related quality of life. The effect is greatest in patients with
