This study describes the introduction of Ondansetron to an established waiting room Oral Rehydration Therapy (ORT) for Emergency Department (ED) children with acute gastroenteritis, and evaluates its impact on intravenous fluid administration and admissions. Children who failed initial ORT while waiting further medical assessment received Ondansetron and ORT reattempted. Data collected over a s...

BACKGROUND & OBJECTIVE: There is inconsistent evidence on using antiemetic drugs (ondansetron and domperidone) in children with vomiting associated gastroenteritis having dehydration. The study's objective was to compare the effectiveness of oral domperidone ondansetron for treating during acute either mild or moderate dehydration.
 METHODOLOGY: This non-controlled quasi-experimental s...

BACKGROUND Palonosetron is a new potent 5-hydroxytryptamine 3 antagonist. Although this drug is thought to be more effective in patients receiving opioid-based patient-controlled analgesia (PCA), clinical data are lacking. This study compared the effects of i.v. ondansetron and palonosetron administered at the end of surgery in preventing postoperative nausea and vomiting (PONV) in high-risk pa...

BACKGROUND 5-HT3 antagonists, such as ondansetron (Zofran), retard colonic transit and provide effective relief of symptoms of chronic diarrhea and diarrhea-predominant irritable bowel syndrome (IBS), but the mechanism by which ondansetron retards transit is unclear. What is clear is that the frequency of colonic migrating motor complexes (CMMCs) is reduced by ondansetron, which could account f...

OBJECTIVE To compare the effectiveness of a single intramuscular dose of bromopride, metoclopramide, or ondansetron for treating vomiting. METHODS Randomized controlled trial including children 1-12 years of age presenting with acute vomiting at the pediatric emergency department. OUTCOMES Number of children that stopped vomiting at one, six, and 24h following treatment; episodes of diarrhe...

UNLABELLED Postoperative vomiting (POV) after ambulatory surgery remains a major problem. We designed this study to determine the smallest dose of dolasetron equivalent to the Food and Drug Administration approved dose of ondansetron 100 micro g/kg IV, for the prophylaxis of POV in children undergoing surgery. In this double-blinded controlled study, 204 healthy ASA I-II children aged 2-12 yr, ...

OBJECTIVE Severe drinking can cause serious morbidity and death. Because the serotonin transporter (5-HTT) is an important regulator of neuronal 5-HT function, allelic differences at that gene may modulate the severity of alcohol consumption and predict therapeutic response to the 5-HT(3) receptor antagonist, ondansetron. METHOD The authors randomized 283 alcoholics by genotype in the 5'-regu...

This is a descriptive retrospective case series of 14 pregnant women treated with ondansetron for hyperemesis gravidarum (HG) at CHU Sainte-Justine, from January 2002 to October 2011. Two of the patients received ondansetron during two separate pregnancies. Both pregnancies were analyzed separately for the purposes of this study. Another woman had twins who were included in the analysis. Theref...

The effects of ondansetron, a highly potent and selective 5-HT3 receptor antagonist, in the prevention of tolerance to and dependence on morphine were studied in mice using a 9-day schedule. Chronic administration of morphine (10 mg/kg i.p. twice daily for 9 days) produced tolerance to the analgesic effects and animals showed withdrawal jumps on day 10 when challenged with naloxone (2 mg/kg). C...
