Lumbar fusion surgery is usually prompted by chronic back pain, and many patients receive long-term preoperative opioid analgesics. Many expect surgery to eliminate the need for opioids. We sought to determine what fraction of long-term preoperative opioid users discontinue or reduce dosage postoperatively; what fraction of patients with little preoperative use initiate long-term use; and what predicts long-term postoperative use. This retrospective cohort study included 2,491 adults undergoing lumbar fusion surgery for degenerative conditions, using Oregon's prescription drug monitoring program to quantify opioid use before and after hospitalization...

AIMS: To describe consumption trends of three groups of analgesics (non-opioids, mild and strong opioids) between 2006 and 2015 in France, and compare this pattern of use with six European countries in 2015. METHODS: Annual drugs sales were extracted from the French national authority's consumption database and from the IMS-MIDAS and national databases for European countries. RESULTS: The use of mild opioids in France decreased by 53% during the last 10 years due to the declining use of dextropropoxyphene combinations, along with an increase in the use of non-opioids and strong opioids (from 72 to 93 and 2 to 2...

BACKGROUND: The mu-opioid antagonist, naltrexone (NTX), is a FDA-approved treatment for alcohol use disorder (AUD); however, the data on whether it differentially affects males vs. females are mixed. NTX increases hypothalamic-pituitary-adrenal (HPA) axis activity that associates with subjective responses to alcohol and craving in individuals with AUD. The present study tested for sex differences in the ability of NTX to decrease appetitive and consummatory behaviors in rats in operant alcohol self-administration...

Although the clinical application of opioids for pain management is often hindered by undesired behavioral impairment, preclinical assays of antinociception typically do not provide information regarding the behaviorally disruptive effects of opioids that may accompany their antinociceptive effects. To address this, we modified a warm water tail withdrawal procedure to determine concurrently the effects of opioids on tail withdrawal latency (antinociception) and indices of food-maintained operant behavior (rates of responding and reinforcement density) in squirrel monkeys...

Phlorotannins, phenolic compounds produced exclusively by seaweeds, have been reported to possess various pharmacological properties. However, there have been few works on these compounds from Mediterranean seaweeds. In this study, we investigated the phytochemical analysis and pharmacological potential of phlorotannin-rich fractions from three brown seaweeds collected along the Tunisia coast: Cystoseira sedoides (PHT-SED), Cladostephus spongeosis (PHT-CLAD), and Padina pavonica (PHT-PAD). Phytochemical determinations showed considerable differences in total phenolic content (TPC) and phlorotannin content (PHT)...

Receptor theory predicts that fixed-proportion mixtures of a competitive, reversible agonist (e.g. fentanyl) and antagonist (e.g. naltrexone) at a common receptor (e.g. mu opioid receptors; MOR) will result in antagonist proportion-dependent decreases in apparent efficacy of the mixtures and downward shifts in mixture dose-effect functions. The present study tested this hypothesis by evaluating behavioral effects of fixed-proportion fentanyl/naltrexone mixtures in a warm-water tail-withdrawal procedure in rhesus monkeys (n=4)...

Introduction: Pain is an unpleasant feeling due to tissue destruction, which disturbs an individual's daily routines even at its lowest levels. The majority of surgeons and anaesthesiologists are increasingly trying to administer non-opioid analgesics because excessive use of opioids after surgery results in patient dissatisfaction. Aim: To evaluate the analgesic effect of intravenous injection of different doses of ketorolac at different intervals in patients undergoing surgery for unilateral fractures of the mandible...

The novel potent analgesic cebranopadol is an agonist at nociceptin/orphanin FQ peptide (NOP) and classical opioid receptors, with the highest in-vitro activity at NOP and mu-opioid peptide (MOP) receptors, and somewhat lower activity at kappa-opioid peptide (KOP) and delta-opioid peptide (DOP) receptors. We addressed the question of which of these pharmacological activities contribute to the stimulus properties of cebranopadol using a rat drug discrimination procedure. First, cebranopadol was tested in generalization tests against a morphine cue, including receptor-specific antagonism...
