Insights

Low-dose cisapride (cisapride) significantly improved gastric emptying and shortened the QTc interval in very low birthweight infants. This study found cisapride safe and effective for improving infant gastric motility.

Area of Science:

  • Neonatal medicine
  • Pediatric pharmacology
  • Gastroenterology

Background:

  • Gastrointestinal dysmotility is common in very low birthweight infants.
  • Assessing the safety and efficacy of prokinetic agents is crucial for this population.

Purpose of the Study:

  • To prospectively evaluate the effects of low-dose cisapride on gastric emptying and QTc interval.
  • To determine the safety profile of cisapride in very low birthweight infants.

Main Methods:

  • A randomized, blind crossover study involving 20 very low birthweight infants.
  • Gastric emptying assessed ultrasonically after 24-hour administration of low-dose cisapride (0.1 mg/kg 8 hourly) or placebo.
  • QTc interval determined after a 7-day course of cisapride or placebo.

Main Results:

  • Cisapride significantly shortened gastric emptying time compared to placebo (p < 0.05).
  • Cisapride significantly shortened the QTc interval compared to placebo (p < 0.05).
  • No apparent adverse effects were observed in any infants.

Conclusions:

  • Low-dose cisapride administration significantly improves gastric emptying in very low birthweight infants.
  • Low-dose cisapride does not increase the QTc interval in this population.
  • Cisapride appears to be a safe and effective treatment for improving gastric motility in neonates.

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

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,...

Drugs for Treatment of Constipation-Predominant IBS

Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists01:28

Drugs Affecting GI Tract Motility: Dopamine Receptor Antagonists

Prokinetic agents are specialized medications that stimulate gastrointestinal (GI) motility, promoting food movement through the GI tract. Dopamine, an inhibitory neurotransmitter, plays a significant role in this process, reducing GI motility and indirectly controlling the speed of digestion. Dopamine receptor antagonists, such as metoclopramide and domperidone, offer a unique advantage as prokinetic agents. By blocking the dopamine receptors, these drugs increase GI motility, improving food...
Gastric Emptying01:16

Gastric Emptying

Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...
