The relationships of characteristics of the initial opioid prescription and pain etiology with the probability of opioid discontinuation were explored in this retrospective cohort study using health insurance claims data from a nationally representative database of commercially insured patients in the U.S. We identified 1,353,902 persons aged ≥14 with no history of cancer or substance abuse, with new opioid use episodes and categorized them into 11 mutually exclusive pain etiologies. Cox Proportional Hazards models were estimated to identify factors associated with time to opioid discontinuation...

OBJECTIVE: Opioid abuse has become an epidemic in the United States, causing nearly 50,000 deaths a year. Postoperative pain is an unavoidable consequence of most surgery, and surgeons must balance the need for sufficient analgesia with the risks of overprescribing. Prescribing narcotics is often the responsibility of surgical residents, yet little is known about their opioid-prescribing habits, influences, and training experience. DESIGN: Anonymous online survey that assessed the amounts of postoperative opioid prescribed by residents, including type of analgesia, dosage, and number of pills, for a series of common general surgery procedures...

Importance: Opioid use disorder (OUD) is a significant public health problem. Supervised withdrawal (ie, detoxification) from opioids using clonidine or buprenorphine hydrochloride is a widely used treatment. Objective: To evaluate whether tramadol hydrochloride extended-release (ER), an approved analgesic with opioid and nonopioid mechanisms of action and low abuse potential, is effective for use in supervised withdrawal settings. Design, Setting, and Participants: A randomized clinical trial was conducted in a residential research setting with 103 participants with OUD...

BACKGROUND: It is well known that powdery drugs such as cocaine and heroin are frequently adulterated or diluted predominantly to obtain more doses and to increase the drug dealer's profits, but also to enhance, to modify or to oppose drug effects. METHODS: The aim of this report is to provide an overview of the recent scientific literature on medicines as well as on new psychoactive substances, used as cutting agents (i.e. pharmacologically active adulterants) and on the related adverse health effects on consumers, possibly due to the synergistic effect of the adulterants laced with substances of abuse, which represent a matter of great concern because of the frequent fatalities...

Postoperative pain control remains an important issue in the field of surgery. Assessing and managing patients with acute pain who are addicted to opioids are often challenging. It has been shown that, addicted patients are less tolerant to pain. There is limited evidence to guide the management of acute pain in these patients. Here we studied the effect of preemptive use of carbamazepine on pain behavior and serum IL-6, IL-10 levels in the addicted patients. 90 male patients (25-45 years, BMI 20-27), were divided into 3 group of 30 patients: 1- control, 2- addicted, 3- addicted patients receiving carbamazepine 400mg before surgery...

Opioid-induced glial activation is hypothesized to contribute to the development of tolerance to opioid-induced analgesia. This inpatient, double-blind, placebo-controlled, within-subject and between-groups pilot study investigated the dose-dependent effects of ibudilast, a glial cell modulator, on oxycodone-induced analgesia. Opioid-dependent volunteers were maintained on morphine (30mg, PO, QID) for two weeks and received placebo ibudilast (0mg, PO, BID) during the 1st week (days 1-7). On day 8, participants (N=10/group) were randomized to receive ibudilast (20 or 40mg, PO, BID) or placebo for the remainder of the study...

Confirmation or exclusion of recent heroin consumption is still one of the major challenges for forensic and clinical toxicologists. A great variety of biomarkers is available for heroin abuse confirmation, including various opium alkaloids (e.g. morphine, codeine), street heroin impurities (e.g. 6-acetylcodeine (6-AC), noscapine, papaverine) as well as associated metabolites (e.g. 6-monoacetylmorphine (6-MAM), morphine glucuronides). Though, the presence of most of these biomarkers cannot solely be attributed to a previous heroin administration but can, among other things, also be due to consumption of poppy seed products ('poppy seed defense'), opium preparations or specific medications, respectively...

Heroin clandestine laboratories have been a feature of the Malaysian illicit drug scene soon after the abuse of heroin emerged in 1972. The first few heroin clandestine laboratories which synthesised heroin via the acetylation of imported morphine were uncovered in 1973 and 1977. By the mid 1980s this type of laboratories was replaced by heroin cutting laboratories whereby imported high grade heroin was cut to street heroin. This was to meet the rising demand for the drug owing to the rapid escalation of the number of drug users...

Heroin consumption in major cities across China was estimated for the first time via wastewater-based epidemiology. Influent and effluent wastewater samples were collected from 49 wastewater treatment plants (WWTPs) in 24 major cities that cover all the geographic regions of the country. Concentrations of morphine, 6-acetylmorphine, and codeine were measured. Near complete removal of morphine by wastewater treatment processes was observed, whereas removal rates of codeine were slightly lower. Morphine loads were much higher than codeine loads at most WWTPs in China, a trend opposite to that in many European countries...

OBJECTIVE: We sought to determine the correlation between the probability of postoperative opioid prescription refills and the amount of opioid prescribed, hypothesizing that a greater initial prescription yields a lower probability of refill. BACKGROUND: Although current guidelines regarding opioid prescribing largely address chronic opioid use, little is known regarding best practices and postoperative care. METHODS: We analyzed Optum Insight claims data from 2013 to 2014 for opioid-naïve patients aged 18 to 64 years who underwent major or minor surgical procedures (N = 26,520)...

The worth of crayfish as a model system for studies of addiction was not previously recognized because a drug-reward phenomenon had not been documented in this model system. In our previous experiments, we demonstrate that the crayfish natural reward pathways are sensitive to human drugs of abuse. This finding supports crayfish as a suitable model to characterize specific behaviors that are relevant in drug addiction research, and the current study builds on our previous findings. The aim of the present study was to investigate unconditioned neurobehavioral effects of repeated treatment regimens using cocaine, morphine, and methamphetamine for three consecutive days...

Chronic pain is a multifaceted and complex condition that is divided into somatic, visceral, and neuropathic pain. Although opioids and nonsteroidal anti-inflammatory drugs cause analgesia and are effective in the treatment of chronic pain, their utility is hampered by side effects, abuse potential, and development of tolerance to their pain-relieving effects. So, finding alternative analgesics with good efficacy and low side effects is of great interest and the orexinergic system is a potential candidate. Orexin-A and -B are exclusively expressed in the lateral hypothalamus and are involved in the feeding, sleep/wake cycle, cardiovascular function, hormone secretion, seizure, and pain modulation...

Heroin is an illicit opioid drug which is commonly abused and leads to dependence and addiction. Heroin is considered a pro-drug and is rapidly converted to its major active metabolite 6-monoacetylmorphine (6-MAM) which mediates euphoria and reward through the stimulation of opioid receptors in the brain. The aim of this study was to investigate the distribution and localization of 6-MAM in the healthy Sprague Dawley rat brain following intraperitoneal (i.p) administration of heroin (10 mg/kg), using matrix-assisted laser desorption/ionization mass spectrometric imaging (MALDI-MSI), in combination with quantification via liquid chromatography mass spectrometry (LC-MS/MS)...

Eating poppy seeds can cause a positive urine drug screen, but it is unknown whether ingesting large quantities can result in opiate intoxication or toxicity. A 54-year-old woman with intractable vomiting was found unresponsive at home and later pronounced dead. At autopsy, a cast-like large bowel obstruction composed of poppy seeds was identified. Postmortem blood morphine level was < 10 ng/mL. Cause of death was determined to be complications of a bowel obstruction secondary to poppy seed ingestion. Deaths related to eating poppy seeds have not been described in the literature...

Opioids are one of the most problematic illegal substances globally. Opioid abuse is associated with complications in various spheres of the user's life, his/her family, and the society. Injecting drug use (IDU) is also linked to public health problems such as HIV infection and viral hepatitis. Medications form an important cornerstone in the treatment of opioid dependence. Treatment strategies such as "detoxification" alone or long-term treatment with opioid antagonist have limited acceptability and retention rates...

Substance use among pregnant women is a major public health issue. Both prescription opioid use and illicit opioid abuse have increased dramatically in recent years. Prolonged in utero drug exposure may result in neonatal abstinence syndrome (NAS), an acute multisystemic clinical entity that occurs in the first days of life. This syndrome is caused by abrupt discontinuation of fetal exposure to licit or illicit drugs chronically consumed by the mother during pregnancy and transmitted to the fetus through the placenta...

BACKGROUND: Tramadol is an opioid analgesic licensed for use in moderate to severe pain. It is considered as a low risk for abuse, so control regulations are not as stringent as for 'strong' opioids such as morphine. It has a potential role as a step 2 option of the World Health Organization (WHO) analgesic ladder. OBJECTIVES: To assess the benefits and adverse effects of tramadol with or without paracetamol (acetaminophen) for cancer-related pain. SEARCH METHODS: We searched the following databases using a wide range of search terms: the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and LILACS...

BACKGROUND AND AIMS: Prescription Drug Monitoring Programs (PDMPs) are a principal strategy used in the USA to address prescription drug abuse. We (1) compared opioid use pre- and post-PDMP implementation and (2) estimated differences of PDMP impact by reason for Medicare eligibility and plan type. DESIGN: Analysis of opioid prescription claims in US states that implemented PDMPs relative to non-PDMP states during 2007-2012. SETTING: Florida, Louisiana, Nebraska, New Jersey, Vermont, Georgia, Wisconsin, Maryland, New Hampshire, and Arkansas, USA...

Development of an efficacious, non-addicting analgesic has been challenging. Discovery of novel mechanisms underlying addiction may present a solution. Here we target the neurokinin system, which is involved in both pain and addiction. Morphine exerts its rewarding actions, at least in part, by inhibiting GABAergic input onto substance P (SP) neurons in the ventral tegmental area (VTA), subsequently increasing SP release onto dopaminergic neurons. Genome editing of the neurokinin 1 receptor (NK1R) in the VTA renders morphine non-rewarding...
