  • Title: Functional dyspepsia. Current treatment recommendations.
    Author: Holtmann G, Talley NJ.
    Journal: Drugs; 1993 Jun; 45(6):918-930. PubMed ID: 7691499.
    Abstract:
    Symptoms of functional dyspepsia are frequent; the prevalence of dyspepsia (defined as pain or discomfort centred in the upper abdomen) in the general population approaches 25%. By definition, patients with functional dyspepsia do not have a structural or biochemical explanation for their symptoms. Disorders of function (e.g. delayed gastric emptying) are detectable in a proportion of patients but remain poorly understood. Nevertheless, the current rationale for drug treatment is based on altering pathophysiological mechanisms which are believed to be associated with the development of symptoms. Although the placebo response rates approach 60%, prokinetics, acid-suppressing agents and bismuth-containing compounds have been shown to be significantly better than placebo in reducing symptoms. Antacids are widely used, but no controlled study has been able to demonstrate a significant benefit over placebo. The efficacy of sucralfate is uncertain. Rational guidelines on which drug should be used for a given patient are lacking, although approaches based on symptom profiles have been proposed; the duration of treatment needed to achieve long-lasting relief of symptoms is also poorly defined. Identifying optimal treatment for the individual patient, therefore, continues to be largely a trial and error process. Further research efforts are needed to elucidate the pathophysiological basis of functional dyspepsia so that specific therapy can be tailored to underlying pathophysiological disturbances.
