Insights

This study on alizapride pharmacokinetics in children found that plasma clearance decreases with age. Higher alizapride doses per body weight are recommended for infants and children compared to adults.

Area of Science:

  • Pharmacology
  • Pediatric Oncology
  • Clinical Pharmacokinetics

Background:

  • Alizapride is used to manage chemotherapy-induced nausea and vomiting.
  • Optimizing alizapride dosage in pediatric patients is crucial for effective treatment.
  • Limited pharmacokinetic data exists for alizapride in children.

Purpose of the Study:

  • To determine the pharmacokinetics of alizapride in children aged 1 month to 15 years.
  • To provide data for optimizing alizapride dosing regimens in pediatric cancer patients.

Main Methods:

  • A single 4 mg/kg intravenous infusion of alizapride was administered to 17 pediatric patients.
  • Blood and urine samples were collected up to 10 hours post-infusion.
  • Pharmacokinetic parameters were calculated to analyze drug disposition.

Main Results:

  • Plasma clearance of alizapride, normalized for body weight, decreased with increasing age.
  • Alizapride exhibited age-dependent pharmacokinetic variability in the pediatric population.

Conclusions:

  • Pediatric patients, particularly infants, may require higher alizapride doses per unit of body weight than adults.
  • These findings support the need for age-specific dosing adjustments for alizapride in children receiving chemotherapy.

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...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight, compared...

Pharmacokinetics in Pediatric Patients: Drug Excretion

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

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...

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,...
