Abstract
INTRODUCTION Metoclopramide is recommended for adults with breakthrough or refractory chemotherapy-induced nausea and vomiting (CINV) and for CINV prophylaxis in children. The drug regulatory agencies of Canada and the EU have revised the labelling of metoclopramide to contraindicate its use in children aged <1 year and to caution against its use in children aged <5 years and its duration of use beyond 5 days. OBJECTIVE This review describes the safety of metoclopramide in children when given for any indication. METHODS We conducted electronic searches in MEDLINE and Embase as of 9 March 2015. All studies in English reporting adverse effects associated with the use of metoclopramide in children (aged ≤18 years) were included. Adverse effects that had a cumulative incidence of at least 1 % and were reported in prospective studies were synthesized. RESULTS A total of 108 (57 prospective) studies involving 2699 patients (2745 metoclopramide courses) were included. The most common adverse effects reported in prospective studies of metoclopramide in children were extrapyramidal symptoms (EPS; 9 %, 95 % confidence interval [CI] 5-17), diarrhea (6 %, 95 % CI 4-9), and sedation (multiple-dose studies: 6 %, 95 % CI 3-12). Dysrhythmia, respiratory distress/arrest, neuroleptic malignant syndrome, and tardive dyskinesia were rarely associated with metoclopramide use. LIMITATIONS The definitions of adverse effects reported in the included studies were heterogeneous, and the risk of bias in most studies was moderate. CONCLUSIONS The most commonly reported adverse effects associated with the use of metoclopramide in children-EPS, diarrhea, and sedation-were reversible and of no long-term significance. Adverse effects that were life threatening or slow to resolve were rarely associated with its use in children.

Abstract
BACKGROUND Gastro-esophageal reflux (GER) is the refluxing of gastric contents into the esophagus. Fifty per cent of all infants 0 to 3 months regurgitate at least once a day. This drops to 5% once infants are 10 to 12 months old. Three per cent of parents of 10 to 12 month old infants view this as a problem. OBJECTIVES To investigate the effectiveness of thickened feeds, positioning, and metoclopramide as compared to placebo in improving the outcome of GER in developmentally normal infants aged one month to two years. SEARCH STRATEGY Trials were identified by searching Cochrane Central Register of Controlled Trials (The Cochrane Library 2003), MEDLINE (January 1966 to 23 January 2003), EMBASE (January 1985 to 27 January 2003), and reference lists of articles. Searches in all databases were updated in April 2009. SELECTION CRITERIA Randomised studies (parallel or cross over) which evaluated thickened feeds, positional alternations or metoclopramide for the treatment of GER in children between the age of one month and two years who were developmentally normal. DATA COLLECTION AND ANALYSIS All three reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects information was collected from the trials. MAIN RESULTS Twenty trials involving 771 children met the inclusion criteria: eight dealt with thickened feeds, five with positioning, and seven with metoclopramide. Few comparisons could be made, and so summary measures were often made with two or three studies. Thickened feeds reduce the regurgitation severity score (standardized mean difference (SMD) -0.94;95% confidence interval -1.35 to -0.52), as well as the frequency of emesis (SMD -0.91; confidence interval -1.22 to -0.61). The reflux index was not reduced (weighted mean difference (WMD) 0.48%; 95% confidence interval -3.27 to 4.23). All five positioning studies utilized esophageal pH monitoring as their outcome measure. Elevating the head of the crib for treating reflux in the supine position is not justifiable. The seven metoclopramide studies used a variety of outcomes. Compared to placebo, metoclopramide appears to reduce daily symptoms ( SMD -0.73; 95% confidence interval -1.16 to -0.30), and reduce the reflux index (WMD -2.80%; 95% confidence interval -5.58 to -0.01). It does increase side effects. AUTHORS' CONCLUSIONS Thickened feeds are helpful in reducing the symptoms of GER. Elevating the head of the crib in the supine position does not have any effect. Metoclopramide may have some benefit in comparison to placebo in the symptomatic treatment for GER, but that must be weighed against possible side effects. .

Abstract
Gastro-esophageal reflux (GER) is a common phenomenon, characterized by the regurgitation of the gastric contents into the esophagus. Gastro-esophageal reflux disease (GERD) is the term applied when GER is associated with sequelae or faltering growth. The main aims of treatment are to alleviate symptoms, promote normal growth, and prevent complications. Medical treatments for children include (i) altering the viscosity of the feeds with alginates; (ii) altering the gastric pH with antacids, histamine H(2) receptor antagonists, and proton pump inhibitors; and (iii) altering the motility of the gut with prokinetics, such as metoclopramide and domperidone. Our aim was to systematically review the evidence base for the medical treatment of gastro-oesophageal reflux in children. We searched PubMed, AdisOnline, MEDLINE, and EMBASE, and then manually searched reviews from the past 5 years using the key words 'gastro-esophageal' (or 'gastroesophageal'), 'reflux', 'esophagitis', and 'child$' (or 'infant') and 'drug$' or 'therapy'. Articles included were in English and had an abstract. We used the levels of evidence adopted by the Centre for Evidence-Based Medicine in Oxford to assess the studies for all reported outcomes that were meaningful to clinicians making decisions about treatment. This included the impact of clinical symptoms, pH study profile, and esophageal appearance at endoscopy. Five hundred and eight articles were reviewed, of which 56 papers were original, relevant clinical trials. These were assessed further. Many of the studies considered had significant methodological flaws, although based on available evidence the following statements can be made. For infant GERD, ranitidine and omeprazole and probably lansoprazole are safe and effective medications, which promote symptomatic relief, and endoscopic and histological healing of esophagitis. Gaviscon(R) Infant sachets are safe and can improve symptoms of reflux. There is less evidence to support the use of domperidone or metoclopramide. More evidence is needed before other anti-reflux medications can be recommended. For older children, acid suppression is the mainstay of treatment. The largest evidence base supports the early use of H(2) receptor antagonists or proton pump inhibitors.

Abstract
OBJECTIVES Metoclopramide is a commonly used drug to treat gastroesophageal reflux disease in infants. Given its widespread use and growing concern about toxicity in this population, we conducted a systematic review of metoclopramide for the treatment of gastroesophageal reflux disease in infants. METHODS We performed a systematic search of PubMed and bibliographies of relevant review articles. We included cohort, case-control, and intervention studies of the efficacy, effectiveness, or toxicity of metoclopramide therapy for gastroesophageal reflux disease in infants. We excluded case reports, case series, review articles, and abstracts. RESULTS Twelve articles met our inclusion criteria. Of these, 11 were prospective trials, and 5 were randomized, blinded clinical trials. Study size ranged from 6 to 77 patients. Eight studies showed patient improvement with metoclopramide in at least 1 measured outcome; 1 study showed worsening symptoms with metoclopramide. Of the 5 randomized, blinded trials, 2 showed no effect of metoclopramide on any outcome, and 2 showed a significant placebo effect. Four studies commented on adverse effects of therapy, with irritability being the most frequently reported potential adverse effect of therapy. Other reported adverse effects included dystonic reactions, drowsiness, oculogyric crisis, emesis, and apnea. Among studies, there was marked heterogeneity in the patient populations, dosing, and outcomes studied. Therefore, a meta-analysis was not performed. We both agreed on a US Preventive Service Task Force rating of "poor" for the level of evidence, leading to an "inconclusive" recommendation for the safety and efficacy of metoclopramide in infants. CONCLUSIONS The current literature is insufficient to either support or oppose the use of metoclopramide for gastroesophageal reflux disease in infants. In the future, large blinded randomized clinical trials are needed to determine the efficacy and toxicity of metoclopramide in this population.

Abstract
OBJECTIVE To review the pharmacology, safety, and efficacy of the prokinetic agents metoclopramide and erythromycin in children. DATA SOURCES English-language literature was accessed using MEDLINE (1970-June 2004) with metoclopramide, erythromycin, macrolides, gastroesophageal reflux, and gastrointestinal motility as the search terms. STUDY SELECTION AND DATA EXTRACTION Abstracts and original research articles were included. Preference was given to published controlled trials. Articles providing descriptions of pharmacology, safety, and effectiveness of metoclopramide and erythromycin for the treatment of gastroesophageal reflux (GER) were also used in this review. DATA SYNTHESIS Some authors advocate using a prokinetic agent along with acid suppression for treatment of GER in children. The 2 prokinetic agents most commonly used are erythromycin and metoclopramide. Erythromycin has numerous observational reports and controlled trials demonstrating its efficacy in improving feeding tolerance in children. Adverse drug reactions associated with its use were uncommon in prospective controlled trials. Few data support the use of metoclopramide for management of GER, and the potential adverse effects associated with its use need to be considered before prescribing. CONCLUSIONS The literature supports the use of erythromycin as a prokinetic agent. Many children with GER are adequately controlled with acid suppression alone; however, if use of a prokinetic agent is warranted, erythromycin in combination with acid suppression should be considered. Given the lack of prospective controlled studies demonstrating metoclopramide's efficacy and safety in the treatment of GER in children, metoclopramide should not be considered a treatment option.

Abstract
Gastroesophageal reflux (GER), defined as passage of gastric contents into the esophagus, and GER disease (GERD), defined as symptoms or complications of GER, are common pediatric problems encountered by both primary and specialty medical providers. Clinical manifestations of GERD in children include vomiting, poor weight gain, dysphagia, abdominal or substernal pain, esophagitis and respiratory disorders. The GER Guideline Committee of the North American Society for Pediatric Gastroenterology and Nutrition has formulated a clinical practice guideline for the management of pediatric GER. The GER Guideline Committee, consisting of a primary care pediatrician, two clinical epidemiologists (who also practice primary care pediatrics) and five pediatric gastroenterologists, based its recommendations on an integration of a comprehensive and systematic review of the medical literature combined with expert opinion. Consensus was achieved through Nominal Group Technique, a structured quantitative method. The Committee examined the value of diagnostic tests and treatment modalities commonly used for the management of GERD, and how those interventions can be applied to clinical situations in the infant and older child. The guideline provides recommendations for management by the primary care provider, including evaluation, initial treatment, follow-up management and indications for consultation by a specialist. The guideline also provides recommendations for management by the pediatric gastroenterologist. This document represents the official recommendations of the North American Society for Pediatric Gastroenterology and Nutrition on the evaluation and treatment of gastroesophageal reflux in infants and children. The American Academy of Pediatrics has also endorsed these recommendations. The recommendations are summarized in a synopsis within the article. This review and recommendations are a general guideline and are not intended as a substitute for clinical judgment or as a protocol for the management of all patients with this problem.

Abstract
Despite its wide use as a prokinetic agent in neonates and infants with gastroesophageal reflux (GER), the pharmacokinetics of metoclopramide have not been characterized in this pediatric subpopulation. A single-dose pharmacokinetic study of oral metoclopramide (0.1 to 0.15 mg/kg) was performed in 10 fasted premature infants (weight 1.1 to 3.2 kg) ranging from 31 to 40 weeks postconceptional age. Metoclopramide was quantitated from repeated blood samples (n = 9 over 24 hours) by high-performance liquid chromatography. A one-compartment open model with first-order absorption best described the plasma concentration-time data. No correlations were observed between gestational, postnatal, or postconceptional age and any of the pharmacokinetic parameters studied. Comparison of the pharmacokinetic parameters from the study cohort and those reported previously from a similar study of older infants revealed no statistically significant differences. However, a prolonged apparent plasma clearance (Cl/F) of metoclopramide was observed in 30% of the infants studied, and the mean Cl/F and apparent steady-state volume of distribution (Vdss/F) were approximately 1.4- and 2.1-fold higher, respectively, than values reported in previous studies of metoclopramide disposition in adults. These data suggest that metoclopramide pharmacokinetics may exhibit a developmental dependency. Thus, a metoclopramide dose of 0.15 mg/kg given orally every 6 hours is recommended for the initiation of prokinetic therapy with this agent in infants who are < or = 31 weeks postconceptional age.

Abstract
BACKGROUND Sequential methods are particularly interesting when recruitment is difficult because they may allow a study to be stopped early while maintaining type I and II error rates. METHODS This placebo-controlled, randomized double-blind study was aimed at assessing the efficacy of metoclopramide (0.2 mg/kg three times daily during 14 days) on gastroesophageal reflux in infancy. The main end point was the relative variation of the percentage of time at pH < 4 between inclusion (day 0) and evaluation (day 14) assessed on two 24-hour esophageal pH recordings. Statistical analysis was performed with use of a sequential method, the triangular test. RESULTS The study was stopped after the seventh analysis (39 infants evaluated: 20 placebo and 19 metoclopramide) without showing the expected benefit. Improvement on the main end point was 30% +/- 48% (mean +/- SD). Corresponding unbiased median estimates were 22% for placebo and 39% for metoclopramide (p = 0.28, sequential analysis). On day 14, the percentage of time at pH < 4 was 8.1% +/- 11.7% for placebo and 6.7% +/- 9.2% for metoclopramide (p = 0.68, t test), and the number of reflux episodes > 5 minutes was 3.0 +/- 3.5 for placebo and 1.9 +/- 3.0 for metoclopramide (p = 0.33, t test). CONCLUSION If a tendency for a superior improvement with metoclopramide than with placebo was observed on the main end point, it was lower than expected and the difference was not significant. Compared with the corresponding single-stage design, the triangular test allowed to stop the study with a 15% reduction in sample size.
