Low-dose naltrexone and opioid consumption: a drug utilization cohort study based on data from the Norwegian prescription database.
Low-dose naltrexone (LDN) is used in a wide range of conditions, including chronic pain and fibromyalgia. Because of the opioid antagonism of naltrexone, LDN users are probably often warned against concomitant use with opioids. In this study, based on data from the Norwegian prescription database, we examine changes in opioid consumption after starting LDN therapy. ⋯ Possibly, LDN users avoided opioids because of warnings on concomitant use or the patients continuing on LDN were less opioid dependent than those terminating LDN. Therapeutic effects of LDN contributing to lower opioid consumption cannot be ruled out. © 2017 The Authors. Pharmacoepidemiology & Drug Safety Published by John Wiley & Sons Ltd.

Opioid-induced hyperalgesia (OIH) is a key factor in the clinical management of patients experiencing pain. However, limited knowledge exists regarding the specific mechanisms involved in OIH and its treatment. ⋯ Patients who are taking opioids should receive ongoing, comprehensive assessment by a clinician. Early identification of OIH will lead to improved patient outcomes. .

Prevalence and clinical features of opioid-induced constipation in the general population: A French study of 15,000 individuals.
Constipation is common during opioid therapy and can compromise analgesia. ⋯ Approximately one-third of a representative French population had used opioids within the previous six months, and 9% of users had experienced OIC, which is more frequent in case of regular use. OIC appears to be under-treated, and participants' satisfaction with their constipation medications was only moderate, suggesting that significant unmet need remains in OIC management.

Cigarette smokers seeking treatment for chronic pain have higher rates of opioid use than nonsmokers. This study aims to examine whether veterans of Operations Enduring Freedom/Iraqi Freedom/New Dawn (OEF/OIF/OND) who smoke are more likely to receive an opioid prescription than nonsmokers, adjusting for current pain intensity. ⋯ We found an association between smoking status and receipt of an opioid prescription. The effect was stronger for current smokers than former smokers, highlighting the need to determine whether smoking cessation is associated with a reduction in opioid use among veterans.

Review Meta Analysis
Polysubstance use and misuse or abuse of prescription opioid analgesics: A multi-level analysis of international data.
Increasing mortality and morbidity associated with opioid analgesics has led to concerns about their misuse and abuse, even when obtained through a prescription. These concerns have been most pronounced in the United States, but limited data make it difficult to determine whether it is a problem in other countries. We investigated opioid analgesic misuse and abuse in participants from the Global Drug Survey 2015 resident in the United States (N = 1334), United Kingdom (N = 1199), France (N = 1258), Germany (N = 866), and Australia (N = 1013) who had used at least 1 prescription opioid analgesic medication in the past year. ⋯ In multilevel models, country of residence accounted for less than 3% of the variance in opioid analgesic misuse or abuse. Adjusting for country of residence and sociodemographic factors, use of illicit drugs and benzodiazepines was associated with 4-fold greater odds of misuse (odds ratio 4.36, 95% confidence interval 3.29-5.93) and 6-fold greater odds of abuse compared with not using either drug (odds ratio 6.49, 95% confidence interval 4.0-10.48), although the strength of the association with abuse varied by country. Misuse and abuse by those prescribed opioid analgesics seem to be a problem that is not limited to the United States and warrant attention on an international scale.
