Abstract

Insights

Neurokinin-1 receptor antagonists effectively prevent delayed chemotherapy-induced nausea and vomiting (CINV). A triple antiemetic regimen with NK-1R antagonists is superior to dual agents, and patient risk factors influence CINV occurrence.

Area of Science:

  • Oncology
  • Pharmacology
  • Gastroenterology

Background:

  • Neurokinin-1 receptor antagonists represent a significant advancement in managing Chemotherapy-Induced Nausea and Vomiting (CINV).
  • Understanding patient-specific risk factors is crucial for optimizing antiemetic regimens.
  • Prophylactic antiemetic strategies are essential for improving patient tolerance to chemotherapy.

Purpose of the Study:

  • To assess the efficacy of Neurokinin-1 Receptor (NK-1R) antagonists in preventing chemotherapy-induced vomiting.
  • To evaluate the role of NK-1R antagonists in both acute and delayed phases post-chemotherapy.
  • To identify patient-related risk factors associated with CINV.

Main Methods:

  • A study involving 145 adult cancer patients receiving dual or triple antiemetics.
  • Data collected from patients treated at Shanghai Changhai Hospital between September and November 2017.
  • Focus on the first cycle of chemotherapy treatment.

Main Results:

  • Triple antiemetic regimens including NK-1R antagonists were more effective in controlling delayed vomiting (4.1% vs. 15.6%, P=0.041).
  • A history of motion sickness was identified as a predictor for CINV (P=0.023).
  • Low alcohol consumption and a history of chemotherapy-induced vomiting (CIV) in males were associated with CINV in the delayed phase (P=0.036 and P=0.002, respectively).

Conclusions:

  • Triple antiemetic therapy with NK-1R antagonists demonstrates superior efficacy in preventing delayed chemotherapy-induced vomiting compared to dual agents.
  • Specific patient risk factors, including motion sickness history, alcohol consumption, and gender-specific history of CIV, are significantly associated with CINV.
  • Personalized antiemetic strategies incorporating risk factor assessment can improve CINV management.

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...

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,...

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...

Direct-Acting Cholinergic Agonists: Pharmacokinetics01:31

Direct-Acting Cholinergic Agonists: Pharmacokinetics

Direct-acting cholinergic agonists, such as synthetic choline esters and naturally occurring alkaloids, exert their effects by enhancing the actions of acetylcholine and stimulating the parasympathetic nervous system. Synthetic choline esters share structural similarities with acetylcholine. For example, they have a positively charged quaternary ammonium or onium group, contributing to their hydrophilic characteristics. As a result, they are poorly absorbed in the body through oral...

Indirect-Acting Cholinergic Agonists: Pharmacokinetics

Indirect-acting cholinergic agonists, or anticholinesterases, enhance the body's cholinergic activity by inhibiting acetylcholine's breakdown. They are categorized as reversible or irreversible agents based on their mechanism of action. They are further classified into short-acting, intermediate-acting, and long-acting agents based on their duration of action.
Reversible agents containing quaternary amines, such as neostigmine and edrophonium, are not easily absorbed orally because they...
