Tramadol is a synthetic opioid with a central effect from the aminocyclohexanol group, which has two main mechanisms of action, including as a weak agonist of opioid receptors and as a norepinephrine and serotonin reuptake inhibitor. The present study presents a review based on clinical trials designed in 2023. In July 2023, six international databases, including Medline/PubMed, ProQuest, Scopus, EMBASE, Google Scholar, and ISI (Web of Science), were searched and 58 articles were included in the study. The results of most studies showed that tramadol can be used as an analgesic drug, although in some studies it was shown that tramadol is not therapeutically superior in reducing pain compared to other treatments. Also, complications related to this treatment have been reported in some studies. Physicians should consider these factors to prevent drug toxicity, poor pain relief, use disorder in patients, and unpredictable complications. It should be noted that there is not enough evidence to support the long-term effectiveness of tramadol, but this argument also extends to nonopioid and other types of opioid analgesics, and the lack of long-term trials is due to regulatory and ethical issues. Although opioids can cause addiction when used for a long time, tramadol has a reasonable safety profile. According to the patient's condition and the clinical judgment of the medical professional, tramadol can be prescribed for patients, but the consequences of its use must be considered and a personalized treatment algorithm should be selected if the benefits outweigh the risks of the drug.

This cohort study aims to assess the outcomes of fibromyalgia patients enrolled in the UK Medical Cannabis Registry prescribed a homogenous selection of cannabis-based medicinal products (CBMPs). A cohort study of fibromyalgia patients treated with oils (Adven^®, Curaleaf International, UK), dried flower (Adven^®, Curaleaf International, UK) or both CBMPs was performed. Primary outcomes were changes from baseline at 1, 3, 6 and 12 months in validated patient-reported outcome measures. Secondary outcomes included descriptive analysis of adverse events. One hundred and forty-eight participants were treated with oils (n = 77; 52.03%), dried flower (n = 14; 9.46%) or both (n = 57; 38.51%). Improvements in the generalized anxiety disorder-7 questionnaire, single-item sleep quality scale, fibromyalgia symptom severity score and EQ-5D-5L Index values were observed at each follow up period compared to baseline (p < 0.050). Thirty-six (24.32%) patients experienced 648 adverse events. Improvements were observed across all primary outcomes with no differences observed across different formulations of CBMPs. Adverse events were reported by one-quarter of participants and were more likely to reported by cannabis naïve patients. This present work through focusing on a homogeneous group of CBMPs can help inform randomized controlled trials after observing signals of improvement associated with a specific cultivar of CBMPs.

Buprenorphine has demonstrated benefit for acute and chronic pain and various psychiatric disorders. However, many studies evaluating buprenorphine's effect on psychiatric conditions are not specific to the chronic pain population. This retrospective study was conducted to assess the impact of buprenorphine on depressive symptoms in patients with chronic pain at a Veterans Affairs healthcare facility. Adults with chronic pain started on any formulation of buprenorphine or traditional opioid (non-buprenorphine opioid) with at least two depression screenings between May 1, 2016 and November 1, 2021 were included. The primary outcome was change in depressive symptoms, measured by Patient Health Questionnaire-9 (PHQ-9), from baseline to 6-18 months after starting therapy. Secondary outcomes included changes in Columbia-Suicide Severity Rating Scale and mental health services utilization. Twenty-one patients were included. Median baseline PHQ-9 in the buprenorphine and traditional opioid groups were 14 and 13, respectively. Median change in PHQ-9 was -5 in the buprenorphine group and -1.5 in the traditional opioid group. Compared to traditional opioids, buprenorphine was associated with a greater reduction in depressive symptoms among Veterans with chronic pain. Although this reduction met the threshold for clinically significant improvement, further investigation is needed to evaluate the clinical relevance of these findings.

We present the case of a 45-year-old male with a history of multiple sclerosis complicated by spasticity and paraplegia, who developed altered mental status and type II respiratory failure requiring intubation on the same day his intrathecal baclofen pump was refilled by his pain physician. Shortly after admission, the patient experienced cardiac arrest four times within two hours until the pump contents were aspirated, and the patient was stabilized. This case report emphasizes the significance of vigilance and prompt recognition of intrathecal baclofen poisoning, which can lead to life-threatening toxicities and withdrawals.

Pain management is the hallmark of palliative care; however, pain is commonly underassessed in cases of advanced dementia and delirium (acute confusional state). We present a case of a 66-year-old female patient with severe dementia who was hospitalized because of behavioral changes and sleep disturbance. Symptoms of confusion, disorientation, inattention, and agitation were most severe at night. The patient never complained of any pain. Thorough examination revealed delirium superimposed on dementia with behavioral and psychological symptoms of dementia, frozen shoulder, osteoarthritis, tooth pain, and geriatric syndrome. Treatment with tablets memantine 5 mg q.12 h, donepezil 10 mg q.day, haloperidol 1 mg q.12 h, lorazepam 1 mg q.day (if necessary), acetaminophen 500 mg q.8 h, and methylprednisolone 4 mg q.8 h, along with psychosocial support, improved her symptoms. Pain often manifests as neuropsychiatric symptoms, resulting in inappropriate use of antipsychotics. Precise pain assessment and effective treatment are imperative, particularly in advanced dementia. Underassessed and undertreated pain in dementia may lead to delirium and progression of dementia. It is paramount for future studies to emphasize comprehensive multidimensional pain assessment and total pain to better manage pain in advanced dementia, which will further enhance psychological well-being and quality of life in palliative care.

Ketamine is an N-methyl D-aspartate (NMDA) receptor antagonist used to treat pain at subanesthetic doses. Ketamine is beneficial for pain control in patients who have a high tolerance to opioids and are experiencing opioid-induced hyperalgesia. This study characterizes oral ketamine use for analgesia at a large academic hospital and reports safety outcomes for hospitalized patients. This study was a retrospective electronic health record (EHR) review of patients ≥ 18 years or older receiving oral ketamine. The primary endpoint was median ketamine starting dose and maximum dose (mg/kg/day) during treatment duration. Secondary outcomes included oral Morphine Milligram Equivalents (MMEs), buprenorphine dose, minimum and maximum pain scores on the first and last day of therapy. Safety endpoints were reported. The median starting dose was 1 mg/kg/day, and the median maximum dose was 1.6 mg/kg/day. Median MMEs decreased from the first day to the last day of oral ketamine therapy. The study population experienced a low incidence of safety events overall. Oral ketamine was administered safely for analgesia, with patients receiving ketamine doses that were on the lower end of the established therapeutic range. Evaluation of the efficacy and safety of oral ketamine use for analgesia should be further studied.

In palliative care, family caregivers are partners of multidisciplinary teams in the continuity of care at home. Effective therapeutic management provides optimal relief of distressing symptoms. It requires the acquisition of specific knowledge and care, but it also involves decision-making with ethical implications that increase the stress and burden on caregivers. The themes identified reflect the tangled dynamics of managing therapeutic regimens in the complexity of being a family caregiver. Therapeutic management relates to effective symptom management, which requires tasks and skills. This management is filled with uncertainties, fears, and emotions that arise from the complexity, responsibility, and weight represented by managing therapeutic regimens. Family caregivers are presented as coordinating elements within the healthcare system. The role of family caregivers is multidimensional, with numerous tasks and skills needed to support their relatives. Therapeutic management is more than just administering medications and needs to keep up with growing and fluctuating needs.
