11 Treatment of functional dyspepsia

Many functional dyspepsia treatment trials have until recently suffered from important weaknesses in study design. A major problem has been the low number of studies that have used validated outcome measures. Fortunately, progress has been made in this area. The evidence for the efficacy of antacids, H₂-receptor antagonists, omeprazole, domperidone, cisapride and anti-Helicobacter therapy is reviewed. Although several of these have shown benefit, it is unclear whether this may be a result of the inclusion of patients with unrecognized gastro-oesophageal reflux disease. The data on anti-Helicobacter therapy are conflicting.
