Chemotherapy-Induced Nausea and Vomiting: Cannabinoids01:21

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

604
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

458
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...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

676
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

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

523
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 Antagonists01:29

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

731
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...

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

2.4K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Summary
This summary is machine-generated.

Cannabinoid hyperemesis syndrome involves severe nausea and vomiting from heavy cannabis use. Stopping cannabis use is the only effective treatment, despite its antiemetic properties.

Area of Science:

  • Medical Science
  • Pharmacology

Background:

  • Cannabinoid hyperemesis syndrome (CHS) is linked to chronic, heavy cannabis consumption.
  • It presents with severe nausea, intractable vomiting, and abdominal pain.
  • Symptomatic relief is often found with hot baths or showers.

Purpose of the Study:

  • To describe the characteristics of Cannabinoid Hyperemesis Syndrome.
  • To highlight diagnostic challenges and the importance of recognizing CHS.
  • To emphasize the resolution of symptoms upon cessation of cannabis use.

Main Methods:

  • Clinical observation and case review of patients presenting with symptoms consistent with CHS.
  • Analysis of patient history regarding cannabis use patterns and symptom triggers.
  • Evaluation of treatment outcomes based on cessation of cannabis intake.

Main Results:

  • CHS is characterized by recurrent severe nausea, vomiting, and abdominal pain in chronic, heavy cannabis users.
  • Hot bathing provides temporary symptom relief.
  • Complete resolution of symptoms occurs after discontinuing cannabis use.

Conclusions:

  • Cannabinoid hyperemesis syndrome is a distinct clinical entity associated with heavy cannabis use.
  • Misdiagnosis is common, leading to unnecessary investigations and treatments.
  • Cessation of cannabis use is the primary and most effective treatment for CHS.
