Abstract
BackgroundControversies persist regarding the effect of prokinetics for the treatment of functional dyspepsia (FD). This study aimed to assess the comparative efficacy of prokinetic agents for the treatment of FD.MethodsRandomized controlled trials (RCTs) of prokinetics for the treatment of FD were identified from core databases. Symptom response rates were extracted and analyzed using odds ratios (ORs). A Bayesian network meta-analysis was performed using the Markov chain Monte Carlo method in WinBUGS and NetMetaXL.ResultsIn total, 25 RCTs, which included 4473 patients with FD who were treated with 6 different prokinetics or placebo, were identified and analyzed. Metoclopramide showed the best surface under the cumulative ranking curve (SUCRA) probability (92.5%), followed by trimebutine (74.5%) and mosapride (63.3%). However, the therapeutic efficacy of metoclopramide was not significantly different from that of trimebutine (OR:1.32, 95% credible interval: 0.27–6.06), mosapride (OR: 1.99, 95% credible interval: 0.87–4.72), or domperidone (OR: 2.04, 95% credible interval: 0.92–4.60). Metoclopramide showed better efficacy than itopride (OR: 2.79, 95% credible interval: 1.29–6.21) and acotiamide (OR: 3.07, 95% credible interval: 1.43–6.75). Domperidone (SUCRA probability 62.9%) showed better efficacy than itopride (OR: 1.37, 95% credible interval: 1.07–1.77) and acotiamide (OR: 1.51, 95% credible interval: 1.04–2.18).ConclusionsMetoclopramide, trimebutine, mosapride, and domperidone showed better efficacy for the treatment of FD than itopride or acotiamide. Considering the adverse events related to metoclopramide or domperidone, the short-term use of these agents or the alternative use of trimebutine or mosapride could be recommended for the symptomatic relief of FD.

Summary
Controversies persist regarding the effect of prokinetics for the treatment of functional dyspepsia (FD). Functional dyspepsia (FD) is a common condition in clinical practice [1]. According to the Rome III and IV criteria, FD is defined as the presence of at least one of the following symptoms; postprandial fullness, early satiation, epigastric pain or burning, without evidence of structural disease to explain the symptoms fulfilling time criteria for the last three months with symptom onset at least six months before diagnosis and a frequency of at least three days per week [2, 3]. This condition involves complex pathophysiologic mechanisms and shares overlapping symptoms with gastroesophageal reflux disease or other functional gastrointestinal disorders. In a subtype of FD, the response rate of epigastric pain syndrome to
