Peripheral neuropathic pain (PNP) poses a significant clinical challenge. The long-term efficacy of delta-9-tetrahydrocannabinol (THC)/cannabidiol (CBD) oromucosal spray was investigated in this 38-week open-label extension study. In total, 380 patients with PNP associated with diabetes or allodynia entered this study from two parent randomised, controlled trials. Patients received THC/CBD spray for a further 38 weeks in addition to their current analgesic therapy. Neuropathic pain severity was the primary efficacy measure using a pain 0-10 numerical rating scale (NRS). Additional efficacy, safety and tolerability outcomes were also investigated. In total, 234 patients completed the study (62 %). The pain NRS showed a decrease in score over time in patients from a mean of 6.9 points (baseline in the parent studies) to a mean of 4.2 points (end of open-label follow-up). The proportion of patients who reported at least a clinically relevant 30 % improvement in pain continued to increase with time (up to 9 months); at least half of all patients reported a 30 % improvement at all time points. Improvements were observed for all secondary efficacy outcomes, including sleep quality 0-10 NRS scores, neuropathic pain scale scores, subject global impression of change and EQ-5D questionnaire scores. THC/CBD spray was well tolerated for the study duration and patients did not seek to increase their dose with time, with no new safety concerns arising from long-term use. In this previously difficult to manage patient population, THC/CBD spray was beneficial for the majority of patients with PNP associated with diabetes or allodynia.

Domperidone 20 mg, droperidol 2.5 mg, metoclopramide 10 mg and placebo (saline) were given i.v. 10 min before the end of anaesthesia, to 200 women undergoing major gynaecological surgery, and the incidence of postoperative nausea and vomiting following a standard anaesthetic technique was assessed. Droperidol was significantly more effective than domperidone, metoclopramide or placebo in reducing emetic sequelae. There were no significant differences between the groups in the incidence of extrapyramidal effects and postoperative sedation. Patients given droperidol required less postoperative analgesia than those given domperidone or metoclopramide. It was concluded that, of the drugs studied, droperidol alone was effective in protecting against nausea and vomiting after major gynaecological surgery.

ObjectivesThe Maine Diversion Alert Program grants healthcare providers access to law enforcement data on drug charges. The objectives of this report were to analyse variations in drug charges by demographics and examine recent trends in arrests, prescriptions of controlled substances and overdoses.DesignObservational.SettingArrests, controlled prescription medication distribution and overdoses in Maine.ParticipantsDrug arrestees (n=1272) and decedents (n=2432).Primary outcome measuresArrestees were analysed by sex and age. Substances involved in arrests were reported by schedule (I–V or non-controlled prescription) and into opioids, stimulants or other classes. Controlled substances reported to the Drug Enforcement Administration (2007–2017) were evaluated. Drug-induced deaths (2007–2017) reported to the medical examiner were examined by the substance(s) identified.ResultsMales were more commonly arrested for stimulants and schedule II substances. More than two-thirds of arrests involved individuals under the age of 40. Individuals age >60 were elevated for oxycodone arrests. Over three-fifths (63.38%) of arrests involved schedule II–IV substances. Opioids accounted for almost half (44.6%) of arrests followed by stimulants (32.5%) and sedatives (9.1%). Arrests involving buprenorphine exceeded those for oxycodone, hydrocodone, methadone, tramadol and morphine, combined. Prescriptions for hydrocodone (−56.0%) and oxycodone (−46.9%) declined while buprenorphine increased (+58.1%) between 2012 and 2017. Deaths from 2007 to 2017 tripled. Acetylfentanyl and furanylfentanyl were the most common fentanyl analogues identified.ConclusionsAlthough the overall profile of those arrested for drug crimes in 2017 involve males, age <40 and heroin, exceptions (oxycodone for older adults) were observed. Most prescription opioids are decreasing while deaths involving opioids continue to increase in Maine.
