Gabapentin for Chronic Refractory Cancer Cough

Vagal sensory neuropathy or vagal hypersensitivity has been implicated in the pathophysiology of chronic cough. Earlier reports have shown gabapentin to be effective in sensory laryngeal neuropathy and symptom conditions that have a proven neural origin. We present a case report of a patient with chronic refractory cough due to a soft tissue mass in the lung that caused compression of the mediastinal structures. The patient was successfully treated with gabapentin with reduction in the cough intensity, duration, and frequency.
