Insights

Ondansetron may help stop vomiting in children with gastroenteritis shortly after administration and reduce the need for IV rehydration. However, evidence is insufficient to recommend its routine use in pediatric acute gastroenteritis.

Area of Science:

  • Pediatric Gastroenterology
  • Clinical Pharmacology

Background:

  • Vomiting is a frequent symptom in pediatric acute gastroenteritis.
  • Current treatment strategies for vomiting in children with gastroenteritis lack consensus.

Purpose of the Study:

  • To evaluate the efficacy of ondansetron compared to placebo or no intervention for treating vomiting in children with acute gastroenteritis.
  • To assess ondansetron's impact on rehydration needs, hospitalization, and emergency department visits.

Main Methods:

  • A systematic review of randomized-controlled trials (RCTs) was conducted.
  • Electronic databases including MEDLINE, EMBASE, CINAHL, and The Cochrane Library were searched through August 2006.
  • Four RCTs involving 490 pediatric patients were included in the analysis.

Main Results:

  • Ondansetron significantly increased short-term vomiting cessation (RR 1.3, 95% CI 1.2-1.5).
  • The drug significantly reduced the need for intravenous rehydration (RR 0.4, 95% CI 0.3-0.7).
  • No significant differences were observed in hospitalization rates or return emergency department visits.

Conclusions:

  • Ondansetron demonstrates short-term benefits in reducing vomiting and the need for IV rehydration in children with acute gastroenteritis.
  • Insufficient evidence currently supports the routine recommendation of ondansetron for this indication in pediatric patients.

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates these...
Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists01:29

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...
Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through interaction...

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Drugs Affecting GI Tract Motility: Adsorbents as Antidiarrheal Agents

Diarrhea is characterized by the occurrence of frequent, watery bowel movements. Various factors can trigger diarrhea, including viral or bacterial infections, foodborne illnesses, side effects from certain medications, and underlying digestive disorders. If not adequately managed, diarrhea can lead to complications such as dehydration, electrolyte imbalances, and nutrient deficiencies. Severe diarrhea can lead to significant weight loss, malnutrition, and weakened immune function.
