“The effectiveness of cannabidiolic acid (CBDA) was compared with other potential treatments for anticipatory nausea (AN), using a rat model of contextually elicited conditioned gaping reactions…
CBDA has therapeutic potential as a highly potent and selective treatment for AN without psychoactive or locomotor effects.”
“Cannabinoid type 1 Receptor (CB1) belongs to the GPCR family and it has been targeted, so far, for the discovery of drugs aimed at the treatment of neuropathic pain, nausea, vomit, and food intake disorders. Here, we present the development of the first fluorescent assay enabling the measurement of kinetic binding constants for CB1orthosteric ligands…
…a sustainable valid alternative to the expensive and environmental impacting radiodisplacement techniques and paves the way for an easy, fast and cheap high-throughput drug screening toward CB1 for identification of new orthosteric and allosteric modulators.”

“Cannabis was extensively used as a medicine throughout the developed world in the nineteenth century but went into decline early in the twentieth century ahead of its emergence as the most widely used illicit recreational drug later that century. Recent advances in cannabinoid pharmacology alongside the discovery of the endocannabinoid system (ECS) have re-ignited interest in cannabis-based medicines.
The ECS has emerged as an important physiological system and plausible target for new medicines. Its receptors and endogenous ligands play a vital modulatory role in diverse functions including immune response, food intake, cognition, emotion, perception, behavioural reinforcement, motor co-ordination, body temperature, wake/sleep cycle, bone formation and resorption, and various aspects of hormonal control. In disease it may act as part of the physiological response or as a component of the underlying pathology.
In the forefront of clinical research are the cannabinoids delta-9-tetrahydrocannabinol and cannabidiol, and their contrasting pharmacology will be briefly outlined. The therapeutic potential and possible risks of drugs that inhibit the ECS will also be considered. This paper will then go on to review clinical research exploring the potential of cannabinoid medicines in the following indications: symptomatic relief in multiple sclerosis, chronic neuropathic pain, intractable nausea and vomiting, loss of appetite and weight in the context of cancer or AIDS, psychosis, epilepsy, addiction, and metabolic disorders.”

“The cannabinoid 1(CB1 ) receptor inverse agonists/antagonists, rimonabant (SR141716, SR) and AM251, produce nausea and potentiate toxin-induced nausea by inverse agonism (rather than antagonism) of the CB1 receptor. Here, we evaluated two phytocannabinoids, cannabidivarin (CBDV) and Δ9 -tetrahydrocannabivarin (THCV) for their ability to produce these behavioural effects characteristic of CB1 receptor inverse agonism in rats.
…we investigated the potential of THCV and CBDV to produce conditioned gaping (measure of nausea-induced behaviour),..
THC, THCV and CBDV suppressed LiCl-induced conditioned gaping, suggesting anti-nausea potential…
The pattern of findings indicates that neither THCV nor CBDV produced a behavioural profile characteristic of CB1 receptor inverse agonists.
As well, these compounds may have therapeutic potential in reducing nausea.”

“For the past 4,000 years, patients and doctors of each era have resorted to cannabis when conventional treatments were ineffective or lacking. Indeed, in oncology beneficial effects have been reported for cancer-associated anorexia, chemotherapy-induced nausea and vomiting, and palliation…
The only U.S. Food and Drug Administration (FDA)-approved medicinal cannabis products are an oral formulation containing dronabinol (Marinol®)… the synthetic version of delta9-tetrahydrocannabinol (THC), the main pharmacologically active cannabinoid, and capsules containing nabilone, an analog of dronabinol (Cesamet®)…
…many patients claim (subjectively) that a whole or partially purified extract of Cannabis sativa L. offers advantages over a single isolated ingredient…
We anticipated an increased use of medicinal cannabis concurrent with anticancer drugs, and undertook a drug-interaction study to evaluate the effect of concomitant medicinal cannabis on the pharmacokinetics of irinotecan and docetaxel…
Conclusion. Coadministration of medicinal cannabis, as herbal tea, in cancer patients treated with irinotecan or docetaxel does not significantly influence the plasma pharmacokinetics of these drugs. The evaluated variety of medicinal cannabis can be administered concomitantly with both anticancer agents without dose adjustments.”

“Biological activity of cannabinoids is caused by binding to two cannabinoid receptors CB1 and CB2. Psychoactive is not only tetrahydrocannabinol (THC) but also: cannabidiol, cannabigerol or cannabichromen.
Formerly, the usefulness of hemp was assessed in the relation to temporary appeasement of the symptoms of some ailments as nausea or vomiting.
Present discoveries indicates that cannabis-based drugs has shown ability to alleviate of autoimmunological disorders such as: Multiple sclerosis (MS), Rheumatoid arthritis (RA) or inflammatory bowel disease.
Another studies indicates that cannabinoids play role in treatment of neurological disorders like Alzheimer disease or Amyotrophic lateral sclerosis (ALS) or even can reduce spreading of tumor cells.
Cannabinoids stand out high safety profile considering acute toxicity, it is low possibility of deadly overdosing and side-effects are comprise in range of tolerated side-effects of other medications.
In some countries marinol and nabilone are used as anti vomiting and nausea drug. First cannabis-based drug containg naturally occurring cannabinoids is Sativex. Sativex is delivered in an mucosal spray for patients suffering from spasticity in MS, pain relevant with cancer and neuropathic pain of various origin.
Cannabis side-effects varies and depend from several factors like administrated dose, rout of administration and present state of mind. After sudden break from long-lasting use, withdrawal symptoms can appear, although they entirely disappear after a week or two.”

“Four years following resection of a Clark’s level IV malignant melanoma, a 50-year-old man developed widespred metastatic disease involving the liver, bones, brain, gastrointestinal mucosa, and lungs. One week after whole brain radiation therapy, he was admitted to the hospital for nausea, vomiting, and pain.
He was treated with several antiemetic drugs, but it was not until dronabinol was added that the nausea and vomiting stopped.
Dronabinol was an effective antiemetic used in combination with prochlorperazine in nausea and vomiting unresponsive to conventional antiemetics.”
“Marijuana has been reported to be an effective antinauseant and antiemetic in patients receiving cancer chemotherapy.
Whether this is due to psychological changes, central antiemetic properties and/or direct effects on gastrointestinal (GI) function is not known. The purpose of these investigations was to determine whether the major constituents of marijuana and the synthetic cannabinoid nabilone have any effects on GI function which can be detected in rodent models of GI transit and motility. Intravenous delta 9-tetrahydrocannabinol (delta 9-THC) slowed the rate of gastric emptying and small intestinal transit in mice and in rats. Delta 9,11-THC, cannabinol and nabilone given i.v. also inhibited small intestinal transit in mice, but were less effective in reducing gastric emptying. Cannabidiol given i.v. had no effect on gastric emptying or intestinal transit. Those cannabinoids which inhibited GI transit did so at doses equal to, or lower, than those reported to produce central nervous system activity. In rats, delta 9-THC produced greater inhibition of gastric emptying and small intestinal transit than large bowel transit, indicating a selectivity for the more proximal sections of the gut. In addition, i.v. delta 9-THC decreased the frequency of both gastric and intestinal contractions without altering intraluminal pressure. Such changes probably reflect a decrease in propulsive activity, without change in basal tone.
These data indicate that delta 9-THC, delta 9,11-THC, cannabinol and nabilone (but not cannabidiol) exert an inhibitory effect on GI transit and motility in rats.”
