Current treatments in functional dyspepsia.
By nature of the definition of functional dyspepsia (FD), organic causes have to be ruled out before therapy can be directed. However, in uninvestigated dyspepsia in the absence of alarm features, Helicobacter pylori "test and treat" or an empiric trial of acid suppression therapy for 4 to 8 weeks is reasonable. If alarm symptoms or signs are present, or if the dyspepsia symptoms first occur in those aged greater than 55 years, prompt esophagogastroduodenoscopy is mandatory to exclude serious disease and positively diagnose FD. Empiric acid suppression with H(2)-receptor antagonists or proton-pump inhibitors is superior to placebo in treatment of FD, but those patients with meal-related symptoms are least likely to respond. Helicobacter pylori eradication in FD benefits a minority of cases but is worthwhile, as response may be maintained. There is increasing evidence that some prokinetics may be superior to placebo in treatment of FD, but probably only a minority respond; those with meal-related symptoms may have the best response. Antidepressant therapy may have a place in management of difficult cases, but adequate randomized controlled trials are unavailable.
