The purpose of this article is to explore the impact of CBD oil on nausea, the benefits, how it compares to traditional medication and the best. Nausea and vomiting are protective defense mechanisms in the body. Short-term episodes can be therapeutic, though miserable. • Cannabis. Here are seven health benefits of CBD oil that are backed by and side effects related to cancer treatment, like nausea, vomiting and pain.

This receptor mediates inhibitory neurotransmission among 5-HT receptors, meaning it dampens signals that are too excited. It is found nearly all over the central nervous system. So how does CBD come into play? When activated, they also:. These receptors are directly activated by CBD and other cannabinoids. These receptors have been identified in the gastrointestinal tract and are theorized to have some connection to the area postrema, including nausea and emesis regulation.
Rats administered with an emetic drug which only makes them nauseous, as rats are unable to vomit were also administered CBD, and it was found that any behavior indicating nausea was effectively eliminated, or strongly inhibited. It was a direct success, significantly decreasing the vomiting which occurred in the shrews. This led the researchers to conclude that the combination of THC and CBDa at sub-threshold doses was an effective antiemetic, and could be used for therapeutic purposes.
This is one of the most undesirable yet obnoxiously consistent side effects of chemotherapy. With many chemo patients describing the rapid onset CINV experience as overpowering , a plethora of antiemetics have been produced to combat the condition. The 5-HT3 antagonists -setrons are the most common, those being:.
Furthermore, the corticosteroid dexamethasone is somewhat effective in treating CINV. Many other drug classes treat CINV:. So, pretty much everything. Nothing quite compares to cannabinoids, however. As you can see, there is strong overlap with the rat and shrew studies in terms of cannabinoid effects on nausea. These are typically very effective, but can carry side effects.
Cannabinoid Hyperemesis Syndrome , or CHS , is a paradoxical and poorly understood affliction sometimes induced in long-time cannabis users. Considering the widespread use of cannabis for treating symptoms such as chronic nausea, CINV, and morning sickness, the very existence of CHS seems absurd. Despite this, a number of studies have shown that CHS can exist in long-time cannabis users, typically resolving following cessation. Patient and public involvement Consumer representatives were involved in the development of this trial.
Trial design The protocol consists of a pilot phase II, double-blinded, randomised, placebo-controlled cross-over study followed by a planned definitive phase III, blinded, randomised, parallel, placebo-controlled trial see figure 1. Open in a separate window. Inclusion criteria Patients who fulfil all of the following characteristics will be considered eligible for enrolment: Adult patients with any malignancy.
Receiving moderate to highly emetogenic intravenous chemotherapy day 1 in a day or day cycle. Exclusion criteria Patients with the following characteristics will be excluded from study enrolment: Radiotherapy to the brain, abdomen or pelvis within the week prior to commencing study treatment, or planned during study treatment.
Contraindication to cannabinoid treatment: Unstable cardiovascular disease uncontrolled hypertension, unstable ischaemic heart disease, unstable congestive cardiac failure.
History of schizophrenia, other psychotic illness, severe personality disorder, suicidal ideation or other significant psychiatric disorder, other than depression associated with the underlying condition. Substance use disorder International Classification of Diseases ICD criteria of abuse or dependence to alcohol, opioids, benzodiazepines, cannabis or illicit stimulants.
Cannabis or cannabinoid-based medications within 30 days of study or unwilling to abstain for the duration of the study.
Prior hypersensitivity or intolerable adverse reaction to cannabis or cannabinoid-based medications, 5HT3 antagonist, dexamethasone or NK1 antagonist. Pregnancy, lactation or inadequate contraception. Women must be postmenopausal, infertile or use a reliable means of contraception. Women of childbearing potential must have a negative pregnancy test done within 7 days prior to registration. Men must have been surgically sterilised or use a double if required barrier method of contraception.
Placebo The placebo will be in white capsules, identical in appearance to that of the active treatment. Randomisation, allocation concealment and double-blind conditions Randomisation will be performed centrally using minimisation, with stratification by chemotherapy emetogenic risk moderate vs high by MASCC criteria and by site.
Recruitment and consent Patient screening and enrolment undertaken at participating sites will be overseen by the site principal investigator and performed by trained study personnel. Table 1 On treatment schedule with dose modifications. Data acquisition The participant will be instructed on the use of the patient diary, which has been designed for this study, to record: Nausea past hour period , recorded using an point rating scale.
Unblinding and poststudy care Following completion of trial treatment, patients who have experienced benefit and require ongoing treatment with the same chemotherapy regimen may be eligible for ongoing access to TN-TC11M, free of charge, contingent on unblinding performed by an unblinded statistician. Statistical considerations Sample size estimation The estimated sample size for the pilot trial is 80 patients 40 per arm , using a primary endpoint of complete response to the study drug and placebo during cycle A and B of treatment.
Health economic analysis A within-trial and modelled economic evaluation will be undertaken to determine the incremental cost-effectiveness of oral cannabinoid therapy compared with placebo and other antiemetic therapies, from a health system perspective.
