The Unfulfilled Promise of Prokinetics for Functional Dyspepsia/Postprandial Distress Syndrome.

ABSTRACT

Functional dyspepsia (FD) is subdivided into epigastric pain syndrome and postprandial distress syndrome according to the Rome IV consensus. Based on the assumption that disordered gastric motility is a key pathophysiologic factor in postprandial distress syndrome, prokinetic agents are often proposed as the treatment of choice for this subgroup. Although a meta-analysis suggests that prokinetic agents may be efficacious and safe in FD, there is a lack of widely available agents of proven efficacy. This review analyzes some of the difficulties and challenges in establishing therapeutic efficacy of prokinetic drugs in FD.
