The use of low dose levomepromazine (methotrimeprazine) in the management of nausea and vomiting

Levomepromazine for nausea and vomiting in palliative care

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.

[Treatment of nausea and vomiting with prokinetics and neuroleptics in palliative care patients : a review]

BACKGROUND

Many recommendations concerning the treatment of nausea and vomiting in palliative care patients exist but what is the evidence for this? Most studies dealing with this topic have focused on cancer patients under chemotherapy and/or radiation therapy or on patients with postoperative nausea. Cancer patients without chemotherapy or radiation therapy, patients without postoperative nausea, and patients having other diseases with palliative care aspects, such as acquired immunodeficiency syndrome (AIDS), chronic obstructive pulmonary disease (COPD), progressive heart failure, amyotrophic lateral sclerosis (ALS) and multiple sclerosis (MS) have been underrepresented in studies on nausea and vomiting so far.

OBJECTIVES

The aim of this review was to determine the level of evidence for the treatment of nausea and vomiting with prokinetics and neuroleptics in palliative care patients suffering from far advanced cancer and no longer being treated with chemotherapy or radiation therapy, AIDS, COPD, progressive heart failure, ALS or MS.

METHODS

Two different electronic databases (PubMed und Embase) were used to identify studies. Furthermore, a hand search for related articles was performed. No restriction was made concerning study types. Studies with patients undergoing chemotherapy radiation therapy or suffering from postoperative nausea, pediatric studies and studies published neither in English nor in German were excluded.

RESULTS

A total of 30 studies fulfilling the inclusion criteria were found. All studies focused on cancer patients. Despite intensive research studies in patients with AIDS, COPD, heart failure, ALS or MS were not detected. Metoclopramide is seen as an effective drug in many studies whereas the evidence for it is moderate at best. Within the group of neuroleptics, levosupiride and levomepromazine seem to have good antiemetic potential but the evidence level is low.

CONCLUSION

In patients with advanced cancer not being treated with chemotherapy or radiation therapy, metoclopramide can be used to reduce nausea and vomiting. Neuroleptics, such as levosulpiride or levomepromazine are alternatives but their adverse effects have to be considered carefully. The evidence level for prokinetics and neuroleptics is moderate to low. Concerning palliative care of patients with diseases other than cancer no studies exist. More well designed studies in palliative care patients are needed in order to facilitate evidence based antiemetic therapy.

Evidence for the use of Levomepromazine for symptom control in the palliative care setting: a systematic review

BACKGROUND

Levomepromazine is an antipsychotic drug that is used clinically for a variety of distressing symptoms in palliative and end-of-life care. We undertook a systematic review based on the question "What is the published evidence for the use of levomepromazine in palliative symptom control?".

METHODS

To determine the level of evidence for the use of levomepromazine in palliative symptom control, and to discover gaps in evidence, relevant studies were identified using a detailed, multi-step search strategy. Emerging data was then scrutinized using appropriate assessment tools, and the strength of evidence systematically graded in accordance with the Oxford Centre for Evidence-Based Medicine's 'levels of evidence' tool. The electronic databases Medline, Embase, Cochrane, PsychInfo and Ovid Nursing, together with hand-searching and cross-referencing provided the full research platform on which the review is based.

RESULTS

33 articles including 9 systematic reviews met the inclusion criteria: 15 on palliative sedation, 8 regarding nausea and three on delirium and restlessness, one on pain and six with other foci. The studies varied greatly in both design and sample size. Levels of evidence ranged from level 2b to level 5, with the majority being level 3 (non-randomized, non-consecutive or cohort studies n = 22), with the quality of reporting for the included studies being only low to medium.

CONCLUSION

Levomepromazine is widely used in palliative care as antipsychotic, anxiolytic, antiemetic and sedative drug. However, the supporting evidence is limited to open series and case reports. Thus prospective randomized trials are needed to support evidence-based guidelines.

The challenge of international consensus: defining an opioid essential prescription package

PURPOSE OF REVIEW

To describe a new strategy that aimed to facilitate opioid prescription for better pain management.

RECENT FINDINGS

The International Association of Hospice and Palliative Care recently develop a single prescription package (drugs and dosing) with one opioid, one laxative, and one antiemetic for the initiation of opioid treatment in cancer pain and other life-threatening conditions, with the intention to facilitate opioid use, improve patient compliance, and reduce adverse effects.

SUMMARY

The opioid essential prescription package was an international project designed to ensure that opioids are better tolerated by reducing the adverse effects of opioids, which could lead to more sustained improvements in pain management.

Review article: palliative care in gynecologic oncology

Patients with advanced gynecologic malignancies have a multitude of symptoms; pain, nausea, and vomiting, constipation, anorexia, diarrhea, dyspnea, as well as symptoms resulting from intestinal obstruction, hypercalcemia, ascites, and/or ureteral obstruction. Pain is best addressed through a multimodal approach. The optimum palliative management of end-stage malignant intestinal obstruction remains controversial, with no clear guidelines governing the choice of surgical versus medical management. Patient selection for palliative surgery, therefore, should be highly individualized because only carefully selected candidates may derive real benefit from such surgeries. There remains a real need for more emphasis on palliative care education in training programs.

Nausea and Vomiting in Advanced Cancer

Nausea and vomiting are relatively common in advanced cancer and is dreaded more than pain by patients. The history, pattern of nausea and vomiting, associated symptoms, and physical examination provides clues as to etiology and may guide therapy. Continuous severe nausea unrelieved by vomiting is usually caused by medications or metabolic abnormalities, while nausea relieved by vomiting or induced by eating is usually due to gastroparesis, gastric outlet obstruction, or small bowel obstruction. Drug choices are empiric or based on etiology. Metoclopramide has the greatest evidence for efficacy followed by phenothiazines and tropisetron. Corticosteroids have not been effective in randomized trials except in the case of bowel obstruction. Treatment of nausea unresponsive to first-line medications involves rotation to medications which bind to multiple receptors (broad-spectrum antiemetics), the addition of another antiemetic to a narrow-spectrum antiemetic (a serotonin receptor antagonist such as tropisetron to a phenothiazine), rotation to a different class of antiemetic (tropisetron for a phenothiazine), or in-class drug rotation. Venting gastrostomy, octreotide, and corticosteroids will reduce nausea and vomiting associated with malignant bowel obstruction.

Palliation of nausea and vomiting

Pain is a common symptom that patients describe and clinicians have to manage. Management plans are tailored to the complexity of the pain. This may require a multi-modal approach while involving the wider multidisciplinary team.

Treatment of nausea and vomiting in terminally ill cancer patients

Nausea and vomiting is a common and distressing symptom complex in patients with far-advanced cancer, affecting up to 60% of individuals at some stage of their illness. The current approach to the palliative care of patients with nausea and vomiting is based on identifying the cause, understanding its pathophysiology and knowing the pharmacology of the drugs available for its amelioration. The following six main syndromes are identified: gastric stasis, biochemical, raised intracranial pressure, vestibular, mechanical bowel obstruction and ileus. A careful history, focused physical examination and appropriate investigations are needed to elucidate the syndrome and its cause, so that therapy is rational. Drugs are the mainstay of treatment in terminal cancer, and the main classes of antiemetic agents are prokinetics, dopamine antagonists, antihistamines, anticholinergics and serotonin antagonists. Dexamethasone and octreotide are also used, especially in bowel obstruction. Non-drug measures are important in relieving the associated distress. Patients should be able to die comfortably, without tubes. Despite decades of practice affirming this approach, the evidence base is weak and well designed studies are urgently needed.

An open study of methotrimeprazine in the management of nausea and vomiting in patients with advanced cancer

INTRODUCTION

Nausea and vomiting are distressing symptoms affecting between 20% and 70% of patients with advanced cancer. Methotrimeprazine is a phenothiazine antipsychotic used in palliative care for the management of terminal agitation and nausea/vomiting but there is only anecdotal evidence to support its use in palliative care.

AIM

To establish whether nausea/vomiting in palliative care patients is improved by the administration of low-dose methotrimeprazine.

METHODS

Patients with advanced malignancy were entered at different treatment levels according to symptom severity. The dose was altered according to response (minimum dose 6.25 mg daily po, maximum 25 mg by 24-h subcutaneous infusion). Symptoms and side effects were recorded daily from 0 (baseline) to day 5 using a four-point scale. Any improvement in nausea/vomiting score was taken as a response.

RESULTS

Sixty-five patients were entered. The cause of nausea and vomiting was multifactorial in the majority of patients, 35/65 (54%). As expected in a study of patients with poor performance status, the attrition rate was high. Of 53 patients evaluable for response at day 2, 33 (62%) showed some improvement in nausea or vomiting. At day 5, improvement was seen in 20/34 (58%). There was no significant change in "side effects" from baseline with time.

CONCLUSION

These results suggest that methotrimeprazine has antiemetic activity.

Low-dose levomepromazine in refractory emesis in advanced cancer patients: an open-label study

Seventy patients with advanced cancer and refractory emesis were treated with subcutaneous boluses of levomepromazine (median daily dose: 6.25 mg; range: 3.12-25) in an open-label prospective study. Treatment was associated with a decrease in nausea from a median of 8/10 at baseline (IQR 7-8) to a median of 1 (IQR 0-2) after two days of treatment (P<0.0001); vomiting ceased in 92% of cases. It was possible to remove the nasogastric tube from all 11 patients who had one. The most frequently reported side effect was sedation, with a median of 2/10 (25-75% percentile 1-3), which was not correlated with the dose of levomepromazine. This study suggests that treatment with low-dose levomepromazine is an effective and safe option for advanced cancer patients who fail to respond to first-line antiemetic treatment.

Olanzapine for intractable nausea in palliative care patients

Nausea is a common problem among palliative care patients, which is often undertreated. Olanzapine, an atypical antipsychotic, possesses a unique neurotransmitter binding profile that is similar to methotrimeprazine, an anti-emetic widely used in Europe for recalcitrant nausea. We report a case series of six patients who suffered nausea which was resistant to initial treatment with traditional antiemetics; each patient exhibited marked improvement when treated with olanzapine.

Use of clinical pictures in the management of nausea and vomiting: a prospective audit

This prospective audit aimed to evaluate a guideline for the management of nausea and vomiting in palliative care inpatients. Clinical pictures were used to guide diagnosis and treatment, with potentially reversible causes being addressed where appropriate. Over a 3-month period, 40 patient episodes occurred, all of which were included in the audit. The commonest clinical pictures were gastric stasis/outlet obstruction (35%) and chemical/metabolic (30%). Management according to the guideline was effective. Nausea was abolished in 28 of 34 cases (82%) and vomiting resolved completely in 26 of 31 cases (84%). Symptoms were totally controlled in a mean time of 3.4 days. Nausea and vomiting, although distressing symptoms, can be controlled in the majority of cases. Multi-centre prospective audit, using a standardized tool, may prove useful in allowing larger numbers of patients to be systematically analysed and individual centres to compare outcomes.

Levomepromazine (methotrimeprazine) and the last 48 hours

Levomepromazine (previously known as methotrimeprazine) has a broad range of beneficial effects in the terminal phase of many illnesses, resulting from its combined antipsychotic, anxiolytic and sedative actions. Levomepromazine can safely be administered in a continuous subcutaneous infusion with most other commonly used drugs in palliative care.

Levomepromazine for nausea and vomiting in advanced cancer

Levomepromazine (previously known as methotrimeprazine), despite virtually no high quality scientific data to support its use, has become a very popular antiemetic for use in patients with advanced cancer. This article considers the reasons for this.

End-of-life care in patients dying of gynecologic cancer

In this article, the patient is considered from the time of disease recurrence, when any treatment is of necessity only palliative, through death. Good symptom control and psychosocial support are needed from the time of diagnosis. As death approaches, specific issues about cessation of active treatment and ethical issues over emergencies become important.

Ondansetron in nausea and vomiting induced by spinal morphine

Nausea and vomiting induced by opioids are relatively frequent in advanced cancer patients, although other factors may play a role. These effects, which tend to disappear after repeated dosing, can usually be controlled with antiemetic drugs, including metoclopramide, haloperidol, and phenothiazines. Occasionally, nausea and vomiting persist, in spite of the prolonged administration of the antiemetic treatment. We report a patient who had nausea and vomiting that was resistant to common antiemetic treatments, change in opioid drugs, and change in route of administration, and who had a complete and immediate response to parenteral or oral ondansetron.
