Summary
Managing chemotherapy-induced nausea and vomiting (CINV) requires a flexible approach. This article details stepped antiemetic strategies using various drug classes for cancer patients.
Area of Science:
- Oncology
- Pharmacology
- Symptom Management
Background:
- Nausea and vomiting are significant side effects of cancer chemotherapy.
- Patient susceptibility to these symptoms varies widely.
- No single antiemetic drug is universally effective for all patients or all chemotherapy regimens.
Purpose of the Study:
- To outline a flexible, stepped management strategy for chemotherapy-induced nausea and vomiting (CINV).
- To discuss the utility of various antiemetic drug classes in managing CINV.
Main Methods:
- Review of antiemetic pharmacotherapy for cancer patients.
- Description of a stepped approach to CINV management.
- Categorization of antiemetic agents including phenothiazines, metoclopramide, cannabinoids, anticholinergics, and antihistamines.
Main Results:
- Individualized antiemetic selection is crucial for effective CINV control.
- Certain antiemetics show differential efficacy depending on the chemotherapeutic agent and patient age.
- A stepped approach allows for titration of therapy based on patient response.
Conclusions:
- A flexible, stepped antiemetic regimen is recommended for managing CINV.
- Combination therapy and individualized treatment plans are key to improving patient outcomes.
- Further research into optimal antiemetic strategies tailored to specific patient populations and treatments is warranted.

01:29Chemotherapy-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.

01:27Chemotherapy-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,...
01:28Chemotherapy-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...
01:21Chemotherapy-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.

Ethical principles are essential in guiding nurses to fulfill their responsibilities, focusing on the quality of nursing care and decision-making. These principles, including autonomy, beneficence, non-maleficence, justice, and fidelity, shape the ethical framework within healthcare settings.

02:50Combination Therapies and Personalized Medicine
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
