Brief Summary:
The purpose of this study is to evaluate the effectiveness of gabapentin on symptom control in patients with defined functional dyspepsia refractory to conventional proton pump inhibitor therapy and to compare these effects to that of placebo.

Condition or disease Intervention/treatment Phase
Functional Dyspepsia Drug: Gabapentin Drug: Placebo Phase 3

Detailed Description:

In this pilot study we hypothesize that the patients on gabapentin will have an increase in the adequacy of dyspepsia symptom control at two months as well as improvement in dyspepsia symptom index scores which are a surrogate of quality of life measures, when compared to placebo.

While functional dyspepsia is divided into four subtypes most studies have grouped all four as 'functional dyspepsia' and treated them as one. Proton pump inhibition may benefit those with epigastric pain or burning but typically not those with post-prandial fullness or early satiety. (Tack et al). Those patients with symptoms refractory to proton pump inhibition might benefit from a medication that modifies visceral hypersensitivity such as gabapentin. It is possible that by modifying their pain syndrome we can decrease the need for follow-up appointments and improve patient quality of life.

Experimental: Gabapentin
Half of the 100 patients enrolled will be placed on Gabapentin therapy to determine if they have improved dyspepsia symptoms.
Drug: Gabapentin
300mg po TID
Other Name: Neurontin

Placebo Comparator: Placebo
Half of the 100 patients will be placed on placebo look-alike of the gabapentin.

Primary Outcome Measures :
  1. The primary outcome will be the adequacy of symptom control during the last week of the study. [ Time Frame: 2 months ]

Secondary Outcome Measures :
  1. Secondary outcomes equate dyspepsia symptoms with quality of life. The Nepean Dyspepsia Index scores patients on five categories while the Global Overall Symptom Scale measures the severity of dyspepsia on a 1-7 scale. [ Time Frame: 2 months ]
