Abstract
BACKGROUND Prokinetics are a class of pharmacological drugs designed to improve gastrointestinal (GI) motility, either regionally or across the whole gut. Each drug has its merits and drawbacks, and based on current evidence as high-quality studies are limited, we have no clear recommendation on one class or other. However, there remains a large unmet need for both regionally selective and/or globally acting prokinetic drugs that work primarily intraluminally and are safe and without systemic side effects. PURPOSE Here, we describe the strengths and weaknesses of six classes of prokinetic drugs, including their pharmacokinetic properties, efficacy, safety and tolerability and potential indications.

Abstract
OBJECTIVE This pilot study aimed to evaluate the efficacy and safety of domperidone for the treatment of Chinese patients with functional dyspepsia (FD) who were diagnosed according to the Rome IV criteria and to identify the FD subtypes that potentially responded better to domperidone. METHODS This multicenter prospective study was conducted in China from August 2018 to July 2020, consisting of a 1-week screening phase and a 2-week double-blind treatment phase. Participants were randomized to receive domperidone 10 mg or matching placebo tablets thrice daily for 14 days. The primary end-point was the overall treatment effect (OTE) response rate after 2-week therapy. RESULTS Altogether 160 patients were included, with 80 patients in each group. The OTE response rate after 2-week therapy was significantly higher for domperidone compared with placebo (60.7% vs 46.0%; relative risk [RR] 1.318, 95% confidence interval [CI] 0.972-1.787). Moreover, the OTE response rate after 2-week domperidone or placebo treatment was 60.3% versus 54.9% for postprandial distress syndrome (PDS) (RR 1.098, 95% CI 0.750-1.607) and 60.6% versus 35.2% for overlapping PDS-epigastric pain syndrome (EPS) (RR 1.722, 95% CI 0.995-2.980). Adverse events were reported by seven patients in the domperidone group and 12 patients in the placebo group. None of the adverse events in the domperidone group were serious. CONCLUSION Domperidone showed a positive pattern regarding OTE response rates after 2-week therapy compared to placebo in patients with FD, as well as in subtypes of PDS and overlapping PDS-EPS. No new safety issue was observed.

Abstract
Acotiamide is a prokinetic with a novel mechanism of action - an antagonist of muscarinic M1 and M2 receptors and an acetylcholinesterase inhibitor. Acetylcholine is the central mediator of the tone of the muscular components of the gastrointestinal tract, increasing its motor activity. Blockade of presynaptic M1 and M2 receptors neutralizes the inhibitory effect of the feedback mechanism on the acetylcholine synthesis, while inhibition of acetylcholinesterase in the synaptic cleft reduces the acetylcholine degradation. Currently, the clinical efficacy of acotiamide in the population of patients with functional dyspepsia is demonstrated in more than 10 clinical studies in different regions of the world, demonstrating a reduction of the symptoms of the disease during treatment with this agent and an improvement in the quality of life of patients. In addition, the combination of acotiamide with proton pump inhibitors optimizes the management of patients with gastroesophageal reflux disease.

Abstract
INTRODUCTION Gastroparesis (Gp) and related disorders such as chronic unexplained nausea and vomiting and functional dyspepsia, known as gastropareis syndromes (GpS), have large unmet needs. Mainstays of GpS treatments are diet and drugs. AREAS COVERED The purpose of this review is to explore potential new medications and other therapies for gastroparesis. Before discussing possible new drugs, the currently used drugs are discussed. These include dopamine receptor antagonists, 5-hydroxytryptamine receptor agonists and antagonists, neurokinin-1 receptor antagonists and other anti-emetics. The article also considers future drugs that may be used for Gp, based on currently known pathophysiology. EXPERT OPINION Gaps in knowledge about the pathophysiology of gastroparesis and related syndromes are critical to developing therapeutic agents that will be successful. Recent major developments in the gastroparesis arena are related to microscopic anatomy, cellular function, and pathophysiology. The major challenges moving forward will be to develop the genetic and biochemical correlates of these major developments in gastroparesis research.

Abstract
BACKGROUND To determine whether central and in vitro administration of urocortin 2 (Ucn 2) affected intestinal inflammatory responses in LPS-stimulated rat models and macrophage cell lines and acotiamide modified mucosal inflammation in this model. METHODS Rats were divided into four groups. LPS-stimulated group (n = 4); LPS- and urocortin 2-treated group (n = 4); LPS- and acotiamide-treated group (n = 4); and LPS-, urocortin 2-, and acotiamide-treated group (n = 4). CD68-, CCR2-, and corticotropin-releasing hormone receptor type 2 (CRHR2)-positive cells were assessed by immunostaining. Myeloperoxidase (MPO) activity was measured. TNF-α, IL-6, and IL-4 levels were measured by ELISA method. Gastric emptying and small intestinal transit time were determined using Evans blue. KEY RESULTS Central administration of Ucn 2 significantly aggravated infiltrations of CD68- and CCR2-positive cells in the intestinal mucosa of LPS-stimulated rat models compared to those in LPS treatment alone. Interestingly, acotiamide treatment significantly reduced the migrations of both CD68- and CCR2-positive cells in the jejunum of central Ucn 2-treated LPS-stimulated rat models. Acotiamide significantly reduced the expression levels of IkB-α phosphorylation in LPS- and MCP-1-stimulated NR8383 cells. Central administration of Ucn 2 significantly delayed gastric emptying. In contrast, Ucn 2 stimulation significantly reduced TNF-α and IL-6 productions in LPS-stimulated NR8383 cells and astressin B reversed the inhibition of TNF-α production in stimulated NR8383 cells. Acotiamide (30 μmol/L) significantly reduced TNF-α and IL-6 productions in LPS- and MCP-1-stimulated NR8383 cells. CONCLUSIONS AND INFERENCES Central and in vitro treatments of Ucn 2 affected intestinal inflammatory responses, respectively, and acotiamide improved them.

Abstract
BACKGROUND Acotiamide, a prokinetic agent was shown to be efficacious in the treatment of functional dyspepsia (FD). The exact mechanism of action is incompletely elucidated. METHODS This randomized, placebo-controlled, cross-over study aimed to examine the effect of acotiamide on gastric motility, measured as intragastric pressure, gastric emptying (GE) rate and gastrointestinal (GI) symptom perception in healthy volunteers (HVs). Participants were treated with acotiamide (100 mg tid) and placebo for 3 weeks, separated by a 1-week washout period. A daily symptom diary was collected during both treatments. At the end of each treatment period, GE rate and gastric motility were assessed with a 13 C-octanoic acid breath test and high-resolution manometry during nutrient infusion, respectively. GI symptom levels were scored during high-resolution manometry. Data were analyzed using mixed models. The study was registered as NCT03402984. KEY RESULTS Twenty HVs (10 female, 25 ± 4.1 years, 22.58 ± 2.73 kg/m2 ) participated in the study. There was no difference in GE half time between both treatments (P = 0.92). Acotiamide had no effect on fundic pressures before and after nutrient infusion (P = 0.91). However, postprandial antral pressures remained significantly lower compared to placebo (P = 0.015). There was no significant difference in hunger, satiation and GI symptoms scores assessed during IGP measurement and by the daily diary (P > 0.12 for all). CONCLUSION Acotiamide is associated with lower antral pressures after nutrient intake, whereas it has no effect on fundic pressures, GE rate and symptom perceptions in HVs. Studies in FD need to elucidate whether lower antral pressures induced by acotiamide underlie postprandial symptom improvement in FD.

Abstract
INTRODUCTION Functional dyspepsia (FD) is a highly prevalent condition which reduces patients' quality of life (QoL) and imparts a significant economic burden on the healthcare system. Acotiamide is a novel prokinetic agent useful in treatment of FD, and this study evaluated the effectiveness of acotiamide hydrochloride hydrate in management of FD over a 4-week period in a real-world setting. METHODS This study was a prospective, observational, real-world data collection of 132 patients (85 male, 47 female) over 18 years of age diagnosed with FD as per Rome III criteria and treated with acotiamide for 4 weeks at a gastroenterology unit of a medical school in India. Those receiving prokinetics and cholinergic drugs, having any structural lesion on endoscopy, with coexisting irritable bowel syndrome and having heartburn in the past 12 weeks were excluded. Primary outcome was responders based on overall treatment efficacy (OTE) recorded on a seven-point Likert scale for postprandial distress syndrome (PDS; postprandial fullness, early satiety and upper abdominal bloating), epigastric pain syndrome (EPS; upper abdominal pain and upper abdominal discomfort) and associated symptoms (nausea, vomiting and excessive belching) at the end of 2 and 4 weeks. Secondary outcomes were elimination of symptoms of PDS, QoL assessed on the Short-Form Nepean Dyspepsia Index (SFNDI) questionnaire and clinical safety after 2 and 4 weeks. RESULTS The responder rates with acotiamide at 2 and 4 weeks were 51.5% and 65.9%, respectively, for PDS. Similarly, the responder rates for EPS were 31.8% and 41.7%, respectively, at 2 weeks and 4 weeks. The responder rates for associated symptoms of nausea, vomiting and excessive belching were respectively 18.2%, 17.4% and 16.7% at 2 weeks and 18.2%, 17.4% and 18.2% at 4 weeks. Symptom elimination rates were 9.8% and 18.9% for postprandial fullness, 12.9% and 22.0% for early satiety, and 18.9% and 24.2% for abdominal bloating at 2 and 4 weeks, respectively. Significant improvement (p < 0.0001) in the SFNDI total scores from 25.91 (5.00) at 2 weeks to 23.76 (4.84) at 4 weeks were found at 4 weeks compared to 2 weeks. A total of 7 (5.30%) patients reported mild adverse events which were dizziness (4), headache (3) and nausea (1). CONCLUSION The current study demonstrates that treatment with acotiamide improves symptoms, QoL and is well tolerated in Indian patients with FD.

Abstract
BACKGROUND Dyspepsia is a common condition associated with gastrointestinal (GI) disease. Prokinetics are the treatment of choice for functional dyspepsia (FD). However, the role of prokinetics in FD treatment is still controversial. OBJECTIVES We conducted a systematic review and meta-analysis of randomised control trials (RCTs) examining the efficacy of prokinetics in the treatment of FD. The primary outcome was overall absence of or improvement of symptoms and symptom scores at the end of treatment. We also evaluated quality of life (QoL) and adverse events as secondary outcomes. SEARCH METHODS We performed a systematic search of MEDLINE, Embase, the Cochrane Library, and CINAHL, from 1946 until September 2017. RevMan 5.3 was used to calculate pooled risk ratios (RR) of symptoms persisting or without improved QoL or adverse events, mean difference (MD) or standardised mean difference (SMD) of post-treatment symptoms scores, changes of symptom scores, and QoL, when appropriate with 95% confidence intervals (CI), using a random-effects model. Quality of evidence was evaluated using GRADE methodology. SELECTION CRITERIA We included studies that were parallel group RCTs comparing one prokinetic with either placebo or another prokinetic of the same or different class for the treatment of FD. Studies involved adults who presented with dyspepsia symptoms and who had negative or insignificant findings on endoscopy as well as no other organic and metabolic disorders. Studies only including participants with primarily reflux or heartburn symptoms were excluded. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study eligibility, study quality and performed data extraction. MAIN RESULTS From an initial 1388 citations, we identified 43 studies in 40 papers. Of those, 29 studies with 10,044 participants compared six prokinetics with placebo for the outcome of absence of symptoms or symptom improvement. There was a statistically significant effect of prokinetic treatment in reducing global symptoms of FD (RR of remaining dyspeptic = 0.81, 95% CI 0.74 to 0.89; number needed to treat for an additional beneficial outcome (NNTB) =7, very low-quality evidence) with considerable heterogeneity; I2 = 91% (P < 0.00001). After removing cisapride from the analysis, the effect of prokinetics in global symptom improvement still persisted, compared to placebo (RR 0.87, 95% CI 0.80 to 0.94), but was still based on very low-quality evidence. The result showed persistence of significant improvement in subgroups of studies at unclear or at low risk of bias (RR 0.86, 95% CI 0.80-0.92), and in subgroups by molecules of cisapride (RR 0.71, 95% CI 0.54 to 0.93; NNTB = 4), acotiamide (RR 0.94, 95% CI 0.91 to 0.98; NNTB = 20) and tegaserod(RR 0.89, 95% CI 0.82 to 0.96; NNTB = 14).Ten studies compared different types of prokinetics with each other and the most commonly used comparator was domperidone, 10 mg three times a day (eight of the 10 studies). There was a significantly better post-treatment symptom score in other prokinetics, compared to domperidone (SMD -0.19, 95% CI -0.35 to -0.03, very low-quality evidence), but no difference in reducing global symptom (RR 0.94, 95% CI 0.83 to 1.07), and mean difference symptom scores (SMD -0.13, 95% CI -0.31 to 0.05). We found five studies that assessed quality of life, but there was no benefit in improving quality of life with prokinetic treatment (SMD 0.11, 95% CI -0.10 to 0.33; participants = 1774). The adverse events in individual prokinetics was not different from placebo (RR 1.09, 95% CI 0.95 to 1.25; participants = 3811; studies = 17). However, when we looked at the adverse effects by each prokinetic, there were overall greater adverse effects in the active treatment group with cisapride (RR 1.31, 95% CI 1.03 to 1.65; P = 0.03). The most common side effects were diarrhoea, abdominal discomfort and nausea. The funnel plot was asymmetric (Egger's test, P = 0.02) implying reporting bias or other small-study effects may be, in part, driving the benefit of prokinetics compared to placebo in this meta-analysis. The GRADE assessment of the quality of the evidence in each outcome are mostly low or very low due to concerns around risk of bias in study design, unexplained heterogeneity and possible publication bias. AUTHORS' CONCLUSIONS Due to low, or very low, quality of evidence, we are unable to say whether prokinetics are effective for the treatment of functional dyspepsia . We are uncertain which of the individual prokinetic drugs is the most effective as well as whether prokinetics can improve quality of life. Apart from cisapride, prokinetics are well-tolerated. Good quality RCTs are needed to verify the efficacy of prokinetics.

Abstract
PURPOSE OF REVIEW The purpose of this article is to review the recent literature and discuss the new approaches to the diagnosis and treatment of functional dyspepsia (FD). RECENT FINDINGS According to the recent American College of Gastroenterology (ACG) and Canadian Association of Gastroenterology (CAG) guideline for dyspepsia, Helicobacter pylori (H. pylori) eradication is recommended as a first treatment option, and proton pump inhibitors (PPIs), tricyclic antidepressants, and prokinetics are listed as second-line therapy. On the other hand, in the Japanese guideline for FD, PPIs and prokinetics are recommended as the first-line treatment. In Japan, acotiamide, a recently launched prokinetic, showed significant efficacy in several clinical trials performed either in Japan or Europe. Regarding non-pharmacological treatment, recent topics include acupuncture, electrical stimulation, gastric peroral endoscopic myotomy, and meal and lifestyle modification. These treatments have provided significant efficacy, which provides some insights into the main pathophysiology of this disease. Although FD is common among functional gastrointestinal disorders, it is not easy to relieve the dyspeptic symptoms of FD patients. Combinations of pharmacological and non-pharmacological treatment options are expected.

Abstract
The food-related behavior of functional dyspepsia has been attracting more interest of late. This pilot study aims to provide evidence of the physiological, emotional, and attentional aspects of food processing in functional dyspepsia patients. The study was performed in 15 functional dyspepsia patients and 17 healthy controls after a standard breakfast. We measured autonomic nervous system activity using skin conductance response and heart rate variability, emotional response using facial electromyography, and visual attention using eyetracking during the visual stimuli of food/non-food images. In comparison to healthy controls, functional dyspepsia patients showed a greater craving for food, a decreased intake of food, more dyspeptic symptoms, lower pleasantness rating of food images (particularly of high fat), decreased low frequency/high frequency ratio of heart rate variability, and suppressed total processing time of food images. There were no significant differences of skin conductance response and facial electromyography data between groups. The results suggest that high level cognitive functions rather than autonomic and emotional mechanisms are more liable to function differently in functional dyspepsia patients. Abnormal dietary behavior, reduced subjective rating of pleasantness and visual attention to food should be considered as important pathophysiological characteristics in functional dyspepsia.

Abstract
BACKGROUND Functional dyspepsia (FD or non-ulcer dyspepsia) is defined as continuous or frequently recurring epigastric pain or discomfort for which no organic cause can be found. Acid suppressive therapy, including proton pump inhibitors (PPIs), has been proposed as a therapeutic option in FD, but its efficacy remains controversial. While PPIs are generally considered safe and well tolerated, they have been associated with adverse events, especially in the long term. For this reason, decisions on whether to initiate or continue PPI therapy should be made based on an appropriate clinical indication. Therefore, we conducted a systematic review to evaluate whether PPI therapy provides symptomatic relief in FD. OBJECTIVES To determine the efficacy of proton pump inhibitors in the improvement of global symptoms of dyspepsia and quality of life compared to placebo, H2 receptor antagonists or prokinetics, in people with functional dyspepsia. SEARCH METHODS We searched in the following electronic databases: the Cochrane Library (to May 2017), MEDLINE (OvidSP; to May 2017), Embase (OvidSP; to May 2017), and SIGLE grey literature (up to May 2017) and clinical trial registries; we handsearched abstracts from conferences up to May 2017. We screened non-systematic reviews, systematic reviews and guidelines to identify any additional trials. We contacted trialists to obtain missing information. SELECTION CRITERIA All randomized controlled trials (RCTs) comparing any PPI with placebo, H2 receptor antagonists (H2RAs) or prokinetics for the treatment of FD of at least two weeks' duration. Participants were adults (aged 16 years or greater) with an adequate diagnosis of FD (any validated criteria such as Rome I, II, III or Lancet Working Group). DATA COLLECTION AND ANALYSIS Two review authors independently assessed eligibility and trial quality, and extracted data. We collected data on dyspeptic symptoms, quality of life and number of overall adverse events. Specific adverse events were beyond the scope of this review. MAIN RESULTS We identified 25 RCTs from 27 papers (with 8453 participants) studying the effect of PPIs versus placebo, H2RAs or prokinetics for improvement of global symptoms of dyspepsia and quality of life in people with FD. Low-dose PPIs had similar efficacy as standard-dose PPIs, therefore we combined these subgroups for the analysis. PPI was more effective than placebo at relieving overall dyspepsia symptoms in people with FD (risk ratio (RR) 0.88, 95% confidence interval (CI) 0.82 to 0.94; participants = 6172; studies = 18; number needed to treat for an additional beneficial outcome (NNTB) 11; moderate quality evidence). PPIs may have little or no effect compared with H2RAs (RR 0.88, 95% CI 0.74 to 1.04; participants = 740; studies = 2; low quality evidence), and may be slightly more effective than prokinetics (RR 0.89, 95% CI 0.81 to 0.99; participants = 1033; studies = 5; NNTB 16; low quality evidence) at relieving overall dyspepsia symptoms in people with FD. PPIs plus prokinetics have probably little or no effect compared with PPIs alone at relieving overall dyspepsia symptoms (RR 0.85, 95% CI 0.68 to 1.08; participants = 407; studies = 2; moderate quality evidence).There was no difference when subgrouped by Helicobacter pylori status, country of origin, or presence of reflux or Rome III subtypes. There were no differences in the number of adverse events observed between PPIs and any of the other treatments. There were fewer adverse events in the combination of PPI plus prokinetics compared to prokinetics alone (RR 0.60, 95% CI 0.39 to 0.93; participants = 407; studies = 2; moderate quality evidence). AUTHORS' CONCLUSIONS There is evidence that PPIs are effective for the treatment of FD, independent of the dose and duration of treatment compared with placebo. PPIs may be slightly more effective than prokinetics for the treatment of FD; however, the evidence is scarce. The trials evaluating PPIs versus prokinetics are difficult to interpret as they are at risk of bias. Although the effect of these drugs seems to be small, the drugs are well tolerated.

Abstract
Patients with functional dyspepsia, defined in the 2016 Rome IV criteria as bothersome clinical dyspepsia symptoms, experience markedly reduced quality of life. Several etiologies have been associated with the disorder. In the Rome IV criteria, the brain-gut axis was acknowledged as an important factor in the etiology of functional gastrointestinal (GI) disorders. The distinct subgroups of functional dyspepsia, epigastric pain syndrome (EPS) and postprandial distress syndrome (PDS), are treated differently: acid secretion inhibitors are recommended with patients with EPS, whereas prokinetic drugs as mosapride and acotiamide are recommended for patients with PDS. A previous study has reported that proton pump inhibitors (PPIs) and H2-blockers were equally effective in functional dyspepsia. A new drug, acotiamide, a muscarinic antagonist and cholinesterase inhibitor, has been shown to improve gastric motility in rodents and dogs, and to reduce PDS symptoms in patients in double-blind multicenter studies. The pharmacological mechanisms of acotiamide remain unknown; whether acotiamide alters gastric emptying and gastric accommodation in patients with functional dyspepsia remains an open question. Other emerging treatment options include Rikkunshito, a herbal medicine that improves gastric emptying through 5-hydroxytryptamine (5-HT)2B-mediated pharmacological action, and tricyclic antidepressants (TCAs). Different drugs are needed to accommodate the clinical symptoms and etiology in individual patients.

Abstract
PURPOSE OF REVIEW Functional dyspepsia affects 10% of the population. Emerging data are beginning to unravel the pathogenesis of this heterogeneous disorder, and new data on treatment are helping to guide evidence-based practice. In this review, the latest advances are summarized and discussed. RECENT FINDINGS The Rome IV criteria were published in 2016 and are similar to Rome III but further emphasize the subtypes (postprandial distress syndrome and epigastric pain syndrome) rather than focussing on the syndrome as a whole, and conclude that gastroesophageal reflux disease and irritable bowel syndrome are part of the functional dyspepsia spectrum. Environment is dominant in the pathogenesis. New data implicate herbivore pets and antibiotic exposure for a nongastrointestinal infection but require confirmation. Further experimental data suggest duodenal eosinophils and mast cells can alter enteric neuronal structure and function in functional dyspepsia. SUMMARY Advances in our understanding of functional dyspepsia are changing clinical practice.
