Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

356
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,...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists01:28

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

236
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 Antagonists01:29

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

399
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 Antagonists01:27

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

290
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,...

Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

901
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Summary

Essential oils show potential for reducing chemotherapy-induced peripheral neuropathy (CIPN) pain, especially when used with pain medications. Further research is recommended for this non-pharmacological approach to cancer treatment side effects.

Area of Science:

  • Oncology
  • Pain Management
  • Complementary and Alternative Medicine

Background:

  • Chemotherapy-induced peripheral neuropathy (CIPN) is a prevalent and debilitating side effect of cancer treatment, affecting up to 60% of patients.
  • Current pharmacological treatments for CIPN often yield limited efficacy and can cause adverse effects.
  • Essential oils represent an underutilized, non-pharmacological strategy for pain reduction in cancer patients.

Purpose of the Study:

  • To evaluate the effectiveness of a topical essential oil intervention in alleviating CIPN symptoms.
  • To explore the potential of essential oils as an adjuvant therapy for managing treatment-related pain.

Main Methods:

  • A pilot, single-blind, randomized controlled trial involving 27 participants stratified by baseline pain.
  • Participants received either a topical essential oil intervention or a placebo for six weeks, applied every eight hours.
  • Pain was assessed weekly via the Short-Form-McGill Pain Questionnaire-2, and daily using the Visual Analogue Scale; quality of life was measured using validated questionnaires.

Main Results:

  • While no significant overall difference in pain or quality of life was found between groups, both showed improvement.
  • A significant reduction in pain was observed in participants using the essential oil intervention concurrently with pain medications compared to placebo (p=0.001).
  • Factors such as educational level, annual income, and age were identified as significant covariates influencing pain perception and outcomes.

Conclusions:

  • The pilot study confirmed participant adherence to the six-week essential oil intervention.
  • Essential oils demonstrate potential for both direct and adjuvant pain-reducing effects in managing CIPN.
  • Further investigation into essential oils for pain management in cancer patients is warranted.
