Regulation of nausea and vomiting by cannabinoids
Cannabinoids are located in the marijuana plant (cannabis sativa) and are said to be efficient in the treating of pain in conditions like nausea and vomiting. Cannabinoids are basically chemical compounds that are naturally occuring in the body and they work on major cannabinoid receptors in cells that control neuronal expulsion in the brains of animals. The endocannabinoid system acts as the breathing ground for these cannabinoids to carry out their anti inflammatory mechanisms. The plant cannabinoid tetrahydrocannabinol (THC) is the main psychotropic chemical in cannabis. Cannabidiol (CBD) is another primary part of the plant and gives off a non psychotic effect. Endogenous cannabinoids have a therapeutic impact in animals, however they are yet to be looked into in depth to cure a wide range of human diseases. This paper will look at the regulation of nausea and vomiting by cannabinoids
Cannabinoids may have a therapeutic value in treating nausea and vomiting
A lot of evidence illustrates that manipulation of the endocannabinoid network mediates nausea and vomiting in humans and other animals. The anti‐emetic impact of cannabinoids has been seen across a wide range of animals that have the ability of vomiting in reaction to a toxic challenge. Cannabinoid receptor 1 agonists prevents vomiting, which is reversed by cannabinoid receptor 1 antagonism, and cannabinoid receptor 1 inverse agonism allows vomiting. In current times, reports from animal experiments indicates that cannabinoids may be especially applicable in helping the more difficult to mediate symptoms of nausea and anticipatory nausea in people with chemotherapy, which are less well mediated by the currently available conventional pharmaceutical drugs. Although rats and mice are not able to promote of vomiting, they show an individualistic conditioned gaping reaction when re‐exposed to cues (flavours or contexts) paired with a nauseating treatment. Cannabinoid agonists and the fatty acid amide hydrolase (FAAH) inhibitor, URB‐597, prevent conditioned responses (nausea) in rats as they prevent vomiting in emetic species. Inverse agonists, but not neutral antagonists, of the cannabinoid receptor 1 allow for nausea, and at certain tolerance injections potentiate nausea made by other bad chemicals. The main non‐psychoactive chemical in cannabis, cannabidiol (CBD), also prevents nausea and vomiting.
Endocannabinoid system in chemotherapy treatment
Animal experiments of vomiting have been required in elucidating the brain actions of the emetic response, however, the neural mechanisms of nausea and vomiting are still not well known. One prevention in the preclinical screening of the vomiting adverse event of chemicals and the plausibility of chemicals to treat nausea has been the little availability of a good preclinical rodent experiment of nausea. Scientists have been applying conditioned taste avoidance in rats for quite a while now as an experiment of nausea and vomiting, but it has been displayed that non‐nauseating therapeutics also produce taste avoidance, it is not a specific measure of nausea. However, the considerable amount of evidence seen above shows that conditioned disgust in rats displayed by an ‘illness‐paired flavour or an illness‐paired context’ hosts a specific and sensitive rodent experiment of nausea. This experiment may be a required instrument for elucidating the neurobiology of nausea and the job that the endocannabinoid network plays in the controlling of this horrible syndrome.Parker_et_al-2011-British_Journal_of_Pharmacology
