Insights

Tropisetron effectively prevents chemotherapy-induced vomiting in children with solid tumors. This selective 5-hydroxytriptamine receptor antagonist demonstrated high efficacy and no adverse effects in pediatric patients.

Area of Science:

  • Oncology
  • Pharmacology
  • Pediatrics

Background:

  • Chemotherapy for solid tumors frequently causes acute vomiting in pediatric patients.
  • Managing chemotherapy-induced nausea and vomiting (CINV) is crucial for treatment adherence and quality of life.
  • Selective 5-hydroxytriptamine receptor antagonists are a key class of antiemetic drugs.

Purpose of the Study:

  • To assess the antiemetic efficacy and tolerability of Tropisetron in pediatric patients receiving chemotherapy.
  • To evaluate Tropisetron's effectiveness in preventing acute vomiting associated with solid tumor treatment.
  • To determine optimal dosing and response based on patient factors and chemotherapy emetogenicity.

Main Methods:

  • A study involving 50 pediatric patients undergoing 189 courses of chemotherapy for solid tumors.
  • Tropisetron administered intravenously 30 minutes prior to chemotherapy.
  • Dosing adjusted by body weight (5 mg for <20 kg, 10 mg for >20 kg) and later evaluated as 8-12 mg/m(2) daily.
  • Emesis control defined as total absence (complete), 1-2 events (major), or >2 events (not controlled).

Main Results:

  • Tropisetron demonstrated high efficacy, completely controlling acute emesis in 92% of chemotherapy courses.
  • Effective in preventing vomiting during moderately and highly emetogenic chemotherapy regimens.
  • No adverse effects were reported at the studied dosage (8-12 mg/m(2)), indicating good tolerability.
  • Response was analyzed considering Tropisetron dosage, patient pretreatment status, and chemotherapy emetogenicity.

Conclusions:

  • Tropisetron is a highly effective and well-tolerated antiemetic for pediatric patients undergoing chemotherapy for solid tumors.
  • The drug provides significant control over acute chemotherapy-induced vomiting.
  • Tropisetron represents a valuable therapeutic option for managing CINV in children.

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: 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: 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...

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...
Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

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...
