Randomized Controlled Trial
Gabapentin for refractory chronic cough: a randomised, double-blind, placebo-controlled trial.
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. We established the efficacy of gabapentin in patients with refractory chronic cough. ⋯ National Health and Medical Research Council of Australia and Hunter Medical Research Institute, Newcastle, Australia.
