Review
Gastroparesis is characterized by a constellation of upper gastrointestinal symptoms in association with delayed gastric emptying in the absence of mechanical outlet obstruction from the stomach. Major symptoms are nausea, vomiting, early satiety or postprandial fullness, bloating, and abdominal or epigastric pain. Idiopathic, diabetic, and postsurgical causes represent the most common etiologies. Diagnostic procedures for the evaluation of gastroparesis comprise gastric emptying scintigraphy (gold standard), (13)C-octanoate breath testing, and a wireless motility capsule. Management of gastroparesis includes normalization of nutritional state, relief of symptoms, glycemic control, and improvement of gastric emptying. Medical treatment entails use of prokinetic drugs, which are currently the first-line therapy. Nausea and vomiting might be positively influenced by antiemetic drugs. Gastric electronic stimulation and surgical interventions should be used in well-defined patients and represent a therapeutic option in tertiary centers.

PloS One 2022To compare patterns in use of different antiemetics during pregnancy in Canada, the United Kingdom, and the United States, between 2002 and 2014.
OBJECTIVE
To compare patterns in use of different antiemetics during pregnancy in Canada, the United Kingdom, and the United States, between 2002 and 2014.
METHODS
We constructed population-based cohorts of pregnant women using administrative healthcare data from five Canadian provinces (Alberta, British Columbia, Manitoba, Ontario, and Saskatchewan), the Clinical Practice Research Datalink from the United Kingdom, and the IBM MarketScan Research Databases from the United States. We included pregnancies ending in live births, stillbirth, spontaneous abortion, or induced abortion. We determined maternal use of antiemetics from pharmacy claims in Canada and the United States and from prescriptions in the United Kingdom.
RESULTS
The most common outcome of 3 848 734 included pregnancies (started 2002-2014) was live birth (66.7% of all pregnancies) followed by spontaneous abortion (20.2%). Use of antiemetics during pregnancy increased over time in all three countries. Canada had the highest prevalence of use of prescription antiemetics during pregnancy (17.7% of pregnancies overall, 13.2% of pregnancies in 2002, and 18.9% in 2014), followed by the United States (14.0% overall, 8.9% in 2007, and 18.1% in 2014), and the United Kingdom (5.0% overall, 4.2% in 2002, and 6.5% in 2014). Besides use of antiemetic drugs being considerably lower in the United Kingdom, the increase in its use over time was more modest. The most commonly used antiemetic was combination doxylamine/pyridoxine in Canada (95.2% of pregnancies treated with antiemetics), ondansetron in the United States (72.2%), and prochlorperazine in the United Kingdom (63.5%).
CONCLUSIONS
In this large cohort study, we observed an overall increase in antiemetic use during pregnancy, and patterns of use varied across jurisdictions. Continued monitoring of antiemetic use and further research are warranted to better understand the reasons for differences in use of these medications and to assess their benefit-risk profile in this population.

The antiemetic properties of marijuana are well known, but there is increasing evidence of its paradoxical hyperemetic effects on the gastrointestinal tract and central nervous system, known as 'cannabinoid hyperemesis syndrome' (CHS). We report a case of CHS encountered in our outpatient clinic. We also completed a review of the literature using PubMed in patients over 18 years of age with CHS. Understanding the diagnostic criteria and risk factors associated with CHS may reduce the ordering of unnecessary and expensive investigations, and pursuing inappropriate medical and surgical treatments. Ultimately, abstaining from cannabis use leads to resolution of symptoms in the majority of patients.

Review
Although prokinetic agents typically are used for gastroparesis, antiemetic, analgesic, and neuromodulatory medications may help manage nausea, vomiting, pain, or discomfort. Antiemetic benefits are supported by few case reports. An open series reported symptom reductions with transdermal granisetron in gastroparesis. Opiates are not advocated in gastroparesis because they worsen nausea and delay emptying. Neuromodulators have theoretical utility, but the tricyclic agent nortriptyline showed no benefits over placebo in an idiopathic gastroparesis study raising doubts about this strategy. Neurologic and cardiac toxicities of these medications are recognized. Additional controlled study is warranted to define antiemetic, analgesic, and neuromodulator usefulness in gastroparesis.

Review
BACKGROUND
This is an updated version of the original Cochrane Review published in Issue 4, 2013, on Levomepromazine for nausea and vomiting in palliative care.Nausea and vomiting are common, distressing symptoms for patients receiving palliative care. There are several drugs which can be used to treat these symptoms, known as antiemetics. Levomepromazine is an antipsychotic drug is commonly used as an antiemetic to alleviate nausea and vomiting in palliative care settings.
OBJECTIVES
To evaluate the efficacy of, and adverse events associated with, levomepromazine for the treatment of nausea and vomiting in palliative care patients.
SEARCH METHODS
For this update we searched electronic databases, including those of Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE, up to February 2015. We searched clinical trial registers on 7 October 2015 for ongoing trials.
SELECTION CRITERIA
Randomised controlled trials of levomepromazine for the treatment of nausea or vomiting, or both, in adults receiving palliative care. We excluded studies in which symptoms were thought to be due to pregnancy or surgery.
DATA COLLECTION AND ANALYSIS
We assessed the potential relevance of studies based on titles and abstracts. We obtained copies of any study reports that appeared to meet the inclusion criteria for further assessment. At least two review authors read each paper to determine suitability for inclusion and discussed discrepancies in order to achieve a consensus.
MAIN RESULTS
In the original review, we identified 421 abstracts using the search strategy. We considered eight studies for inclusion but ultimately excluded them all from the review. We updated the search in February 2015 and identified 35 abstracts, but again none met the inclusion criteria. We identified two trials from clinical trial registers, one of which is ongoing and one of which was closed due to poor recruitment.
AUTHORS' CONCLUSIONS
As in the initial review, we identified no published randomised controlled trials examining the use of levomepromazine for the management of nausea and vomiting in adults receiving palliative care, and our conclusion (that further studies of levomepromazine and other antiemetic agents are needed to provide better evidence for their use in this setting) remains unchanged. We did, however, identify one ongoing study that we hope will contribute to the evidence base for this intervention in future updates of this review.

Review
Chemotherapy-induced nausea and vomiting (CINV) is a significant clinical issue which affects patients' quality of life as well as treatment decisions. Significant improvements in the control of CINV have occurred in the past 15 years with the introduction of new antiemetic agents: 5-HT3 receptor antagonists, tachykinin NK1 receptor antagonists and olanzapine. Aprepitant was the first NK1 receptor antagonist introduced (2003) for the prevention of CINV in combination with a 5-HT3 receptor antagonist and dexamethasone. Two additional NK1 receptor antagonists, netupitant and rolapitant, were approved by the FDA in 2014 and 2015, respectively. A description of rolapitant and its role in CINV will be presented, along with a comparison to the other NK1 receptor antagonists, aprepitant and netupitant.

Review
Chemotherapy-induced nausea and vomiting (CINV) is associated with a significant deterioration in quality of life and is perceived by patients as a major adverse effect of the treatment. This review summarizes the safety and efficacy of current antiemetic agents for the prevention of CINV in children. Information on antiemetic prophylaxis for CINV in children was obtained from a literature review of current peer-reviewed articles and recent international guidelines. The literature review and the international antiemetic guidelines provide recommendations for use of specific antiemetics in children based on the emetogenicity of the chemotherapy. 5-Hydroxytryptamine-3 (5-HT) receptor antagonists have been safe and effective in the prevention of acute emesis with a few patients experiencing mild headache. No adequate studies have been conducted to date for specific recommendations for the prevention of delayed nausea and vomiting in children. The neurokinin (NK)- receptor antagonist aprepitant has been approved by the US FDA for use in children of a specific age and weight. No studies for the NK receptor antagonists netupitant and rolapitant in children have been conducted. Olanzapine, an antipsychotic, has been shown to be safe and effective in preventing nausea and emesis in adult patients receiving chemotherapy. Its use in children has been limited to children with poor control of CINV; more studies are necessary in this population. In conclusion, practitioners should follow international antiemetic guidelines to provide patients with the specific antiemetics in the recommended dose for the highest possible quality of care.

Review
BACKGROUND
Prevention of chemotherapy-induced nausea and vomiting (CINV) can be improved with guideline-consistent use of antiemetics. However, adherence to antiemetic guidelines remains often insufficient. Therefore, new strategies that improve adherence are needed.
OBJECTIVES
To review the latest antiemetic guideline recommendations and provide an update on the use of NEPA, a fixed combination antiemetic composed of the neurokinin-1 receptor antagonist (RA) netupitant and the 5-hydroxytryptamine-3 RA palonosetron (Akynzeo®).
METHODS
Analysis of the literature was performed, including guidelines, published literature, congress data on NEPA, and relevant articles on CINV.
FINDINGS
Nurses are in a unique position to promote guideline-consistent antiemetic prophylaxis and are central in the education of patients and caregivers. Thus, nurses’ continuous education on antiemetic treatments is key for the prevention and management of CINV. NEPA offers a simplified antiemetic therapy with the potential to increase guideline adherence.

Review
Common treatment methods for malignant tumors include surgery, chemotherapy, radiotherapy, immunotherapy, targeted therapy, etc., among which chemotherapy plays an important role. However, chemotherapy brings corresponding side effects while killing tumor cells, and nausea and vomiting are the most common adverse reactions induced by chemotherapy. It not only affects the patient's appetite, resulting in malnutrition and electrolyte disturbances, but also reduces the patient's compliance with treatment, which further aggravates the disease. Thus, it is important to quickly prevent and cure nausea and vomiting induced by chemotherapy (CINV). In addition, with the continuous development of medicine, more and more antiemetic drugs have been developed. At present, the most common antiemetic agents for chemotherapy-induced nausea and vomiting are NK-1R antagonists, 5-HT3R antagonists, and dexamethasone. Surprisingly, olanzapine, often used as a psychotropic drug, has been found to be an effective antiemetic and is similar to other regimens on the safety of medicine. However, although there are numerous studies on the antiemetic effects of olanzapine, its comprehensive application remains unclear. Therefore, this review will elaborate the antiemetic effect of olanzapine in terms of the antiemetic mechanism and the safety, economic cost, dose, administration time, and drug delivery aspects.

PURPOSE OF THE REVIEW
The purpose of review is to critically present the evidence supporting the use of olanzapine, an atypical antipsychotic, as an antiemetic for cancer and chemotherapy-induced nausea and vomiting (CINV).
RECENT FINDINGS
Two phase III clinical studies demonstrated superior efficacy of olanzapine in comparison with the neurokinin-1 receptor antagonists (NK1RA) for substance P (aprepitant, fosaprepitant) in the prevention of nausea after highly emetogenic chemotherapy. Olanzapine is inexpensive and the replacement of NK1RA with olanzapine can reduce the costs of the prevention of CINV. The addition of olanzapine to aprepitant-containing combination regimens for the prevention of CINV was also investigated, and has the potential to further improve the prevention of CINV after highly emetogenic chemotherapy or moderately emetogenic chemotherapy, without substantial increase in costs. In the treatment of uncontrolled ('breakthrough') CINV, olanzapine was more effective than metoclopramide. Existing clinical data also support the use of olanzapine to relieve a cluster of gastrointestinal symptoms in patients with advanced cancer (chronic nausea, vomiting, and anorexia). When used in cancer patients, olanzapine is well tolerated, with sedation being the major dose-limiting side effect.
SUMMARY
Existing data from clinical trials justify further research of the role of olanzapine in the prevention of CINV. Olanzapine may be used instead of or in addition to NK1RA in the preventive antiemetic regimens. Olanzapine-containing preventive regimens may provide better nausea control after chemotherapy. When used instead of NK1RA it may also provide substantial reduction in costs of CINV prevention. In patients with advanced cancer, olanzapine was effective against a cluster of gastrointestinal symptoms (nausea, vomiting, and anorexia). The use of olanzapine as an antiemetic for CINV, or to relieve nausea, vomiting, and anorexia in palliative care is currently off-label.
