Drugs that bind to but do not activate DOPAMINE RECEPTORS, thereby blocking the actions of dopamine or exogenous agonists. Many drugs used in the treatment of psychotic disorders (ANTIPSYCHOTIC AGENTS) are dopamine antagonists, although their therapeutic effects may be due to long-term adjustments of the brain rather than to the acute effects of blocking dopamine receptors. Dopamine antagonists have been used for several other clinical purposes including as ANTIEMETICS, in the treatment of Tourette syndrome, and for hiccup. Dopamine receptor blockade is associated with NEUROLEPTIC MALIGNANT SYNDROME.

Discriminative stimulus effects of naltrexone after a single dose of morphine in the rat. (1/1824)

The discriminative stimulus effects of an acute morphine (MOR) --> naltrexone (NTX) combination were characterized and compared with the stimulus effects of NTX-precipitated and spontaneous withdrawal from chronic MOR administration. Adult male Sprague-Dawley rats (n = 6-8) were trained to discriminate between two drug treatments in a discrete-trial avoidance/escape procedure: MOR (10 mg./kg, s.c., 4 h) --> NTX (0.3 mg/kg, s.c., 0.25 h) versus saline (SAL, 1 ml/kg, s. c., 4 h) --> NTX (0.3 mg/kg, s.c., 0.25 h). Subjects responded only on the SAL --> NTX-appropriate lever when SAL was given 3.75 h after MOR or 3.75 h before any dose of NTX (0.3-100 mg/kg). Responding was dose dependent and MOR --> NTX-appropriate when NTX (0.01-0.1 mg/kg) followed MOR. Full MOR --> NTX-appropriate responding was dependent on the pretreatment dose and time of MOR, with full effects observed only when MOR (10 mg/kg) was given 3 to 4 h before NTX. While subjects were maintained on either 20- or 40 mg/kg/day of MOR via osmotic pump, NTX produced full dose-dependent, MOR --> NTX-appropriate responding. When the MOR-filled pumps were removed, partial MOR --> NTX-appropriate responding occurred, peaking at 6 to 12 h. The physical withdrawal signs produced by NTX after acute or during chronic MOR exposure were of smaller magnitude compared with the ones that occurred during abrupt withdrawal from chronic MOR. A qualitatively unique "withdrawal" stimulus that is dose- and time-dependent appears to be the basis of this MOR --> NTX discrimination.  (+info)

Modulation of Ca2+/calmodulin-dependent protein kinase II activity by acute and chronic morphine administration in rat hippocampus: differential regulation of alpha and beta isoforms. (2/1824)

Calcium/calmodulin-dependent protein kinase II (CaMK II) has been shown to be involved in the regulation of opioid receptor signaling. The present study showed that acute morphine treatment significantly increased both Ca2+/calmodulin-independent and Ca2+/calmodulin-dependent activities of CaMK II in the rat hippocampus, with little alteration in the protein level of either alpha or beta isoform of CaMK II. However, chronic morphine treatment, by which rats were observed to develop apparent tolerance to morphine, significantly down-regulated both Ca2+/calmodulin-independent and Ca2+/calmodulin-dependent activities of CaMK II and differentially regulated the expression of alpha and beta isoforms of CaMK II at protein and mRNA levels. Application of naloxone or discontinuation of morphine treatment after chronic morphine administration, which induced the withdrawal syndrome of morphine, resulted in the overshoot of CaMK II (at both protein and mRNA levels) and its kinase activity. The phenomena of overshoot were mainly observed in the beta isoform of CaMK II but not in the alpha isoform. The effects of both acute and chronic morphine treatments on CaMK II could be completely abolished by the concomitant application of naloxone, indicating that the effects of morphine were achieved through activation of opioid receptors. Our data demonstrated that both acute and chronic morphine treatments could effectively modulate the activity and the expression of CaMK II in the hippocampus.  (+info)

Reproductive experience and opioid regulation of luteinizing hormone release in female rats. (3/1824)

The objective of the present study was to determine whether reproductive experience that produces shifts in opioid regulation of prolactin secretion and behavioural functions also alters opioid regulation of LH during the oestrous cycle or lactation. In Expt 1 the effect of naloxone administration (i.v.) on LH was compared between age-matched, nulliparous and primiparous, catheterized female rats on dioestrus II. In Expt 2, the effects of multiple reproductive experiences on opiate control of LH were investigated using cyclic, nulliparous and multiparous (three litters) rats. In both experiments, no differences in naloxone-stimulated LH release were found between groups even though multiple reproductive experiences resulted in the prolongation of oestrous cyclicity. In Expt 3, day 8 lactating primiparous rats were administered 2, 5, 10 or 25 mg naloxone kg-1 i.v. The three lowest naloxone doses, but not the 25 mg kg-1 dose, significantly increased LH concentrations. The possible effects of prior reproductive experience on opioid control of LH during lactation were then investigated. Naloxone at 0.5 mg kg-1, but not at 2 mg kg-1 or 10 mg kg-1, stimulated a significantly greater rise in LH in multiparous (two litters) than in primiparous females. Overall, these data indicate that while modest differences were found in naloxone-induced LH responses between multiparous and primiparous animals during lactation, reproductive experience did not significantly alter opioid regulation of LH during subsequent oestrous cycles at the naloxone doses examined. Hence, the effects of reproductive experience on opioid regulation of LH are less pronounced than those previously found for opioid regulation of prolactin and behaviour.  (+info)

Morphine preconditioning attenuates neutrophil activation in rat models of myocardial infarction. (4/1824)

Previous results from our laboratory have suggested that morphine can attenuate neutrophil activation in patients with acute myocardial infarction. To elucidate if morphine preconditioning (PC) has the same effects via activation of neutrophil endopeptidase 24.11 (NEP), we measured serum levels of intercellular adhesion molecule-1 (ICAM-1), gp100MEL14 and NEP in adult Wistar rats subjected to ten different protocols (n = 10 for each) at baseline, immediately after and 2 h after morphine PC. All groups were subjected to 30 min of occlusion and 2 h of reperfusion. Similarly, morphine-induced PC was elicited by 3-min drug infusions (100 micrograms/kg) interspersed with 5-min drug-free periods before the prolonged 30-min occlusion. Infarct size (IS), as a percentage of the area at risk (AAR), was determined by triphenyltetrazolium staining. Pretreatment with morphine increased NEP activities (9.86 +/- 1.98 vs. 5.12 +/- 1.10 nmol/mg protein in control group; p < 0.001). Naloxone (mu-opioid receptor antagonist) (4.82 +/- 1.02 nmol/mg protein) and phosphoramidon (NEP inhibitor) (4.66 +/- 1.00 nmol/mg protein) inhibited morphine-activated NEP, whereas glibenclamide (ATP-sensitive potassium channel antagonist) and chelerythrine (protein kinase C inhibitor) had no effects. The ICAM-1 and gp100MEL14 of the third sampling were lowest for those with morphine PC (280 +/- 30 ng/ml and 2.2 +/- 0.7 micrograms/ml; p < 0.001), but naloxone (372 +/- 38 ng/ml and 3.8 +/- 0.9 micrograms/ml) and phosphoramidon (382 +/- 40 ng/ml and 4.2 +/- 1.1 micrograms/ml) abolished the above phenomenon. IS/AAR were definitely lowest for those with morphine PC (24 +/- 7%; p < 0.05). Morphine preconditioning increases NEP activities to attenuate shedding of gp100MEL14 and to ICAM-1 and, thus, provides myocardial protection.  (+info)

Rapid detoxification of heroin dependence by buprenorphine. (5/1824)

AIM: To evaluate the clinical efficacy of buprenorphine (Bup) in treatment of acute heroin withdrawal. METHODS: Bup was given sublingually daily to 60 cases of heroin addicts in 3 groups: low, medium, and high doses. Withdrawal signs and symptoms of heroin were rated by Clinical Institute Narcotic Assessment. Craving for heroin during detoxification was assessed by Visual Analogue Scale. The side effects of Bup was assessed by Treatment Emergent Symptom Scale. RESULTS: The mean daily consumption of Bup in low, medium, and high group was 2.0, 2.9, and 3.6 mg, respectively. Bup not only suppressed objective signs and withdrawal symptoms for heroin withdrawal, but also reduced the duration for heroin detoxification over 7-8 d. CONCLUSION: Bup is an effective and rapid detoxification agent with fewer side effects for treatment of acute heroin withdrawal.  (+info)

Molecular and ligand-binding characterization of the sigma-receptor in the Jurkat human T lymphocyte cell line. (6/1824)

The sigma binding site present in the Jurkat human T lymphocyte cell line was investigated. Jurkat cell membranes were found to have a single saturable binding site for [3H]haloperidol, a sigma ligand (dissociation constant, 3.9 +/- 0.3 nM). The binding of [3H]haloperidol was inhibited by several sigma ligands. Northern analysis and reverse transcription-polymerase chain reaction provided evidence for the expression of the recently cloned type 1 sigma-receptor (sigma-R1) in Jurkat cells. The sigma-R1 cDNA cloned from these cells was functional in heterologous expression systems. When expressed in mammalian cells, the cDNA-induced binding was saturable with dissociation constants of 1.9 +/- 0.3 nM for [3H]haloperidol and 12 +/- 2 nM for (+)-pentazocine. The binding of [3H]progesterone, a putative endogenous ligand to sigma-R1, to the Jurkat cell sigma-receptor could be directly demonstrated by using heterologously expressed sigma-R1 cDNA. The binding of [3H]progesterone was saturable, with a dissociation constant of 88 +/- 7 nM. Progesterone and haloperidol interacted with the receptor competitively. Reverse transcription-polymerase chain reaction also produced evidence for the existence of an alternatively spliced sigma-R1 variant in Jurkat cells. This splice variant was found to be nonfunctional in ligand binding assays. This constitutes the first report on the molecular characterization of the sigma-receptor in immune cells.  (+info)

Modulation of amphetamine-stimulated [3H]dopamine release from rat pheochromocytoma (PC12) cells by sigma type 2 receptors. (7/1824)

An important regulatory mechanism of synaptic dopamine (DA) levels is activation of the dopamine transporter (DAT), which is a target for many drugs of abuse, including amphetamine (AMPH). sigma receptors are located in dopaminergic brain areas critical to reinforcement. We found previously that agonists at sigma2 receptors enhanced the AMPH-stimulated release of [3H]DA from slices of rat caudate-putamen. In the present study, we modeled this response in undifferentiated pheochromocytoma-12 (PC12) cells, which contain both the DAT and sigma2 receptors but not neural networks that can complicate investigation of individual neuronal mechanisms. We found that enhancement of AMPH-stimulated [3H]DA release by the sigma agonist (+)-pentazocine was blocked by sigma2 receptor antagonists. Additionally, the reduction in the effect of (+)-pentazocine by the inclusion of ethylene glycol bis(beta-aminoethyl ether)-N,N,N', N'-tetraacetic acid led us to hypothesize that sigma2 receptor activation initiated a Ca2+-dependent process that resulted in enhancing the outward flow of DA via the DAT. The source of Ca2+ required for the enhancement of reverse transport did not appear to be via N- or L-type voltage-dependent Ca2+ channels, because it was not affected by nitrendipine or omega-conotoxin. However, two inhibitors of Ca2+/calmodulin-dependent protein kinase II blocked enhancement in AMPH-stimulated release by (+)-pentazocine. Our findings suggest that sigma2 receptors are coupled to the DAT via a Ca2+/calmodulin-dependent protein kinase II transduction system in PC12 cells, and that sigma2 receptor antagonists might be useful in the treatment of drug abuse by blocking elevation of DA levels via reversal of the DAT.  (+info)

Nitrocinnamoyl and chlorocinnamoyl derivatives of dihydrocodeinone: in vivo and in vitro characterization of mu-selective agonist and antagonist activity. (8/1824)

Two 14beta-p-nitrocinnamoyl derivatives of dihydrocodeinone, 14beta-(p-nitrocinnamoylamino)-7,8-dihydrocodeinone (CACO) and N-cyclopropylmethylnor-14beta-(p-nitrocinnamoylamino)- 7, 8-dihydrocodeinone (N-CPM-CACO), and the corresponding chlorocinnamoylamino analogs, 14beta-(p-chlorocinnamoylamino)-7, 8-dihydrocodeinone (CAM) and N-cyclopropylmethylnor-14beta-(p-chlorocinnamoylamino) -7, 8-dihydrocodeinone (MC-CAM), were tested in opioid receptor binding assays and the mouse tail-flick test to characterize the opioid affinity, selectivity, and antinociceptive properties of these compounds. In competition binding assays, all four compounds bound to the mu opioid receptor with high affinity. When bovine striatal membranes were incubated with any of the four dihydrocodeinones, binding to the mu receptor was inhibited in a concentration-dependent, wash-resistant manner. Saturation binding experiments demonstrated that the wash-resistant inhibition of mu binding was due to a decrease in the Bmax value for the binding of the mu-selective peptide [3H][D-Ala2, MePhe4,Gly(ol)5] enkephalin and not a change in the Kd value, suggesting an irreversible interaction of the compounds with the mu receptor. In the mouse 55 degrees C warm water tail-flick test, both CACO and N-CPM-CACO acted as short-term mu-selective agonists when administered by i. c.v. injection, whereas CAM and MC-CAM produced no measurable antinociception at doses up to 30 nmol. Pretreatment of mice for 24 h with any of the four dihydrocodeinone derivatives produced a dose-dependent antagonism of antinociception mediated by the mu but not the delta or kappa receptors. Long-term antagonism of morphine-induced antinociception lasted for at least 48 h after i.c. v. administration. Finally, shifts in the morphine dose-response lines after 24-h pretreatment with the four dihydrocodeinone compounds suggest that the nitrocinnamoylamino derivatives may produce a greater magnitude long-term antagonism of morphine-induced antinociception than the chlorocinnamoylamino analogs.  (+info)

The mu-opioid system has a key role in hedonic and motivational processes critical to substance addiction. However, existing mu-opioid antagonists have had limited success as anti-addiction treatments. GSK1521498 is a selective and potent mu-opioid antagonist being developed for the treatment of overeating and substance addictions. In this study, 28 healthy participants were administered single doses of GSK1521498 20 mg, ethanol 0.5 g/kg body weight, or both in combination, in a double blind placebo controlled four-way crossover design. The primary objective was to determine the risk of significant adverse pharmacodynamic and pharmacokinetic (PK) interactions. The effects of GSK1521498 on hedonic and consummatory responses to alcohol and the attentional processing of alcohol-related stimuli, and their modulation by the OPRM1 A118G polymorphism were also explored. GSK1521498 20 mg was well tolerated alone and in combination with ethanol. There were mild transient effects of GSK1521498 on alertness and

Organizations promoting low-dose naltrexone have advocated it as a treatment for a variety of medical conditions.[2] However, currently no peer-reviewed studies that would justify clinical use of low-dose naltrexone in treating Multiple Sclerosis (MS) have been published.[7]. Low-dose naltrexone may relieve certain symptoms in people with multiple sclerosis, although medical practitioners often advise against using it as a substitute to proven therapies,[3][8] and the evidence supporting its use in MS is not robust, as different studies have come to conflicting conclusions.[1] Writing for the National MS Society in 2009, neurologist Alan Bowling called research into low-dose naltrexone encouraging but further research needed to be done before any definitive conclusions could be reached. Bowling noted that safety of low-dose naltrexone treatment for multiple sclerosis has not been assessed, and that patients who chose to undergo the treatment should be fully informed of the limited research ...

Low-dose naltrexone (LDN) describes the off-label use of the medication naltrexone at low doses for diseases such as multiple sclerosis. Naltrexone is typically prescribed for opioid dependence or alcohol dependence, as it is a strong opioid antagonist. Preliminary research has been promising for use of LDN in treating chronic medical conditions such as chronic pain, but at this stage the use of LDN as a treatment is still experimental and more research needs to be done before it can be widely recommended. Some proponents of low-dose naltrexone have brought forth claim about its efficacy in treating a wide range of diseases, including cancer and HIV/AIDS. Low-dose naltrexone organizations have promoted its use on their webpages. Naltrexone is an opioid receptor antagonist, meaning it binds to opioid receptors in cells. These receptors bind endogenous pain relieving compounds such as endorphins as well as opioids such as morphine. Naltrexone also works to bind against the effects of heroin, which ...

Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered the mechanism by which a low dose of the opioid antagonist naltrexone (LDN), an agent used clinically (off-label) to treat cancer and autoimmune diseases, exerts a profound inhibitory effect on cell proliferation. It has been postulated that opioid receptor blockade by LDN provokes a compensatory elevation in endogenous opioids and opioid receptors that can function after LDN is no longer available. Using a novel tissue culture model of LDN action, the mechanism of LDN has been found to target the opioid growth factor (OGF, [Met5]-enkephalin) and OGF receptor (OGFr) axis. This discovery, reported in the September 2011 issue of Experimental Biology and Medicine, provides new insights into the molecular pathway utilized by an increasingly important clinically prescribed agent that serves as a basic biological regulator of cell proliferative events related to pathobiological states such as ...
Treating chronic pain with low dose naltrexone and ultralow dose naltrexone: a review paper., Yoon Hang John Kim*, Kirsten West
We examined the locomotor-enhancing action of mu-opioid receptor agonists, such as morphine and [D-Ala2, N-MePhe4, Gly-ol5]enkephalin (DAMGO), and physical dependence on morphine in diabetic and nondiabetic mice. Morphine (5-20 mg/kg, s.c.) and DAMGO (1-4 nmol, i.c.v.) had a dose-dependent locomotor-enhancing effect in both nondiabetic and diabetic mice. The locomotor-enhancing effects of morphine and DAMGO were significantly less in diabetic mice than in nondiabetic mice, and were significantly reduced after pretreatment with either beta-funaltrexamine (20 mg/kg, s.c.), a selective mu-opioid receptor antagonist, or naloxonazine (35 mg/kg, s.c.), a selective mu1-opioid receptor antagonist. Both diabetic and nondiabetic mice were chronically treated with morphine (8-45 mg/kg, s.c.) for 5 days. During this treatment, neither diabetic nor nondiabetic mice showed any signs of toxicity. After morphine treatment, withdrawal was precipitated by injection of naloxone (0.3-10 mg/kg, s.c.). Several ...

N2 - β-endorphin, deltorphin II, [D-Ala2, Phe4, Gly5-ol-enkephalin (DAGO) as well as endomorphin- 1 and endomorphin-2 injected intracerebroventricularly (icv.) induced gastroprotective action. It has been raised that endogenous opioids may have a central role in maintaining gastric mucosal integrity. Therefore we aimed to study the role of endogenous opioid system in the gastroprotective action induced by activation of α2- adrenoceptors, nociceptin- and cannabinoid- receptors. Our results suggest that the non-selective opioid receptor antagonist naloxone (27 nmol icv.) and the δ-opioid receptor antagonist naltrindole (5 nmol icv.) abolished the mucosal protective effect of α2-adrenoceptor agonists clonidine (470 pmol icv.) and rilmenidine (45 pmol icv.), nociceptin (1 nmol icv.) and the cannabinoid receptor ...

Aims Naltrexone is a competitive opioid antagonist that effectively blocks the action of heroin and other opioid agonists. It has no abuse potential, mild and transient side effects, and thus appears an ideal pharmacotherapy for opioid dependence. Sustained-release naltrexone formulations are now available that provide long-acting opioid blockade. However, further research is warranted, especially data concerning opioid receptor (OR) occupancy on different plasma levels of naltrexone. Positron emission tomography (PET) is a unique imaging modality for studying functional processes in vivo and is used in this study to map OR occupancy on different plasma concentrations of naltrexone in rats. Methods Eleven rats were implanted with a single tablet of 1,95 mg naltrexone. OR occupancy data was acquired at baseline, a few days after implantation (week 1) and in week 6 by PET imaging, using the partial agonist [18F]BPN, the agonist [18F]PEO, and the antagonist [18F]DPN, all OR ligands. Blood samples ...
Whilst it is possible to drink alcohol whilst you are taking LDN, because of the opiate receptor blocker effect of low-dose naltrexone on the body, the feelgood factor from alcohol is much reduced. However, when you are taking any medication, it is always advisable to keep alcohol to a very minimum, maybe limiting a drink to a small glass of wine with a meal.. It is notable that naltrexone, because of its ability to block the opiate receptor and thereby take away the feelgood factor from alcohol, is used in higher doses to reduce the potential possibility of recovering alcoholics, returning to drinking large amounts of alcohol. In this form, naltrexone is used at the normal doses of between 50 and 75 mg. The effect is so helpful that a pharmaceutical preparation mimicking the effect of naltrexone has now been produced in the form of Nalmefene which helps to reduce the amount of alcohol a person drinks. This is available by prescription from a doctor.. ...

Naltrexone, a µ-opioid receptor antagonist, is a promising agent for methamphetamine-using and binge-drinking men who have sex with men (MSM). Naltrexone has shown efficacy in reducing relapse to amphetamines and is FDA-approved for alcohol dependence. Oral naltrexone is inexpensive and has few toxicities but the standard daily regimen for naltrexone is problematic as patients forget to take the medication. Given the challenges in daily dosing, alternate regimen schedules have been proposed to increase efficacy and expand the population that may benefit from this pharmacologic agent. One approach is intermittent targeted administration of naltrexone, whereby individuals take the medication as-needed in anticipation of substance use or during periods of craving. Administration of naltrexone prior to exposure to amphetamines significantly attenuates craving and targeted naltrexone has shown efficacy in reducing heavy alcohol use. However, there have been no studies assessing intermittent targeted ...
Naltrexone Hydrochloride is a pure opioid receptor antagonist. Although well absorbed orally, naltrexone is subject to significant first pass metabolism with oral bioavailability estimates ranging from 5 to 40%. The activity of naltrexone is believed to be due to both parent and the 6-β-naltrexol metabolite. Both parent drug and metabolites are excreted primarily by the kidney (53% to 79% of the dose), however, urinary excretion of unchanged naltrexone accounts for less than 2% of an oral dose and faecal excretion is a minor elimination pathway. The mean elimination half-life (T-1/2) values for naltrexone and 6-β-naltrexol are 4 hours and 13 hours, respectively. The elimination half-life and time to maximum concentration are dose-independent. Naltrexone and 6-β-naltrexol are dose proportional in terms of AUC and Cmax over the range of 50 to 200 mg and there is no significant accumulation after 100 mg daily doses ...

Naltrexone is an opioid antagonist that mediates the rewarding effects of alcohol and attenuates cravings.[75,86,87] Although the exact mechanism of how naltrexone works to reduce alcohol consumption is not completely understood, the presumed major effect is via blockade of opiate receptors that play a role in the reward effects of alcohol.[73] Naltrexone is currently available both as oral naltrexone (50 mg once daily) and extended-release injectable naltrexone (380 mg IM every 4 weeks).[75] Oral naltrexone was approved by the U.S. FDA in 1994 for alcohol dependence or alcoholism. In a large, meta-analysis of randomized, placebo-controlled trials, oral naltrexone was found to have a small but significant effect in reducing craving and relapse: nine people would need to be treated to prevent one additional case of return to heavy drinking (NNT=9).[80] Most of the studies in this meta-analysis were published prior to the U.S. FDA approval in 2006 of extended-release injectable naltrexone. ...
Naltrexone is the generic name for a drug, approved by the FDA in 1984, used to treat alcohol and opioid addiction. Opioids are generally pain-management agents such as morphine, codeine, oxycodone, and fentanyl. Opioids also include heroin and methadone, as well as our own naturally occurring endorphins.The first study of LDN published in a US-based medical journal would come in 2007, with Dr. Jill Smiths article in the Low-dose naltrexone therapy improves active Crohns disease (e-published in January, print published in April). Smith and her team found that 67% of the patients went into remission and fully 89% showed some therapeutic benefit. This encouraging work led to an NIH grant and a Phase II placebo-controlled clinical trial, currently in progress. ...

Fatal drug overdoses, due to both illicit and prescription drug use, have become epidemic in the United States (US). The rate exceeds that of deaths from motor vehicle accidents, largely due to the increase in prescription opioid overdoses.1 In 2013, about 16,000 deaths occurred from prescription opioid overdoses, accounting for more than half of all prescription drug overdose deaths.2 Multiple substances (eg, alcohol, benzodiazepines, and other sedating drugs) often contribute to these overdose deaths. Many opioid overdoses occur in patients with legitimate opioid prescriptions who have identifiable risk factors (see Table 1). This issue provides historical background about the opioid overdose epidemic, followed by information about naloxone - a mu opioid receptor antagonist that is indicated for the treatment of respiratory and/or central nervous system (CNS) depression due to opioid overdose.

Drug overdose death rates have increased steadily in the United States since 1979. In 2008, a total of 36,450 drug overdose deaths (i.e., unintentional, intentional [suicide or homicide], or undetermined intent) were reported, with prescription opioid analgesics (e.g., oxycodone, hydrocodone, and methadone), cocaine, and heroin the drugs most commonly involved (1). Since the mid-1990s, community-based programs have offered opioid overdose prevention services to persons who use drugs, their families and friends, and service providers. Since 1996, an increasing number of these programs have provided the opioid antagonist naloxone hydrochloride, the treatment of choice to reverse the potentially fatal respiratory depression caused by overdose of heroin and other opioids (2). Naloxone has no effect on non-opioid overdoses (e.g., cocaine, benzodiazepines, or alcohol) (3). In October 2010, the Harm Reduction Coalition, a national advocacy and capacity-building organization, surveyed 50 programs known ...

N2 - Naltrexone attenuates craving, and the subjective effects of methamphetamine and extended-release naltrexone (XR-NTX) reduces functional connectivity between regions of the striatum and limbic cortex. Naltrexone modulates neural activity at dopaminergic synapses; however, it is unclear whether naltrexone has an effect on large-scale brain networks. Functional networks interact to coordinate behavior, and as substance-use disorders are associated with an imbalance between reward and cognitive control networks, treatment approaches that target interactive brain systems underlying addiction may be a useful adjunct for behavioral therapies. The objective of this study was to examine the effect of XR-NTX on large-scale ...
Rationale: Opioid antagonists are used to reverse the toxic effects of opioids, to diagnose opioid dependence and to treat opioid and other (alcohol) drug abuse. Objectives: This study compared the discriminative stimulus effects of two opioid antagonists (naloxone and naltrexone), after parenteral and oral administration. Methods: The discriminative stimulus effects of naloxone and naltrexone were evaluated every 15 min over a 2-h period in four morphine-treated (3.2 mg/kg per day) rhesus monkeys discriminating between subcutaneous (SC) injections of naltrexone (0.01 or 0.032 mg/kg) and saline, while responding under a fixed-ratio 5 schedule of stimulus shock termination. Results: Within 15 min of SC administration, naloxone and naltrexone produced greater than 90% drug-appropriate responding at doses of 0.032 and 0.01 mg/kg, respectively. The largest dose of naloxone (3.2 mg/kg) administered orally produced 82% drug-appropriate responding within 90 min; the same dose of naltrexone administered

VANCOUVER ISLAND - Fentanyl test strips were added to Island Healths supervised consumption and overdose prevention sites in late December, allowing on-the-spot testing of drugs before they are consumed.. Sites in Victoria, the city with the third-highest number of overdose deaths in BC this year, were the first locations on Vancouver Island to receive the strips.. Overdose prevention sites in Duncan, Nanaimo, Port Alberni, Courtenay and Campbell River were to receive strips by the end of December. The strips are free to people checking drugs while at an overdose prevention or supervised consumption site.. It isnt a perfect method for detecting contaminants and a risk still exists regardless of the results, which is why we are making them available at supervised consumption and overdose prevention sites, said Dr. Murray Fyfe, Medical Health Officer, Island Health.. We hope that drug checking will become part of a routine for people using drugs at these sites to do so more safely - combining ...
Introduction Death due to opioid overdose was declared a public health crisis in Canada in 2015. Traditionally, patients who have overdosed on opioids that are managed by emergency medical services (EMS) are treated with the opioid antagonist naloxone, provided ventilatory support and subsequently transported to hospital. However, certain EMS agencies have permitted patients who have been reversed from opioid overdose to refuse transport, if the patient exhibits capacity to do so. Evidence on the safety of this practice is limited. Therefore, our intent was to examine the available literature to determine mortality and serious adverse events within 48 hours of EMS treat and release due to suspected rebound opioid toxicity after naloxone administration. ...

In October 2002, the Food and Drug Administration (FDA) approved buprenorphine monotherapy product, Subutex®, and a buprenorphine/naloxone combination product, Suboxone®, for use in opioid addiction treatment. The combination product is designed to decrease the potential for abuse by injection. Subutex® and Suboxone® are currently the only Schedule III, IV, or V medications to have received FDA approval for this indication. Note that aside from Subutex® and Suboxone®, other forms of buprenorphine (e.g., Buprenex®) are not approved for treatment of opioid addiction.. *The FDA approval of these buprenorphine formulations does not affect the status of other medication-assisted opioid addiction treatments, such as methadone and LAAM (levo-alpha-acetyl-methadol). As indicated in Title 42 Code of Federal Regulations Part 8 (42 CFR Part 8), these treatments can only be dispensed, and only in the context of an Opioid Treatment Program.. In the late 90s we began seeing the use of Suboxone ...
Training in the use of naloxone, an easy to administer medication which temporarily reverses an opioid overdose by blocking the opioid receptors in the brain.
The editorial flags one of the major legal issues that gets in the way of wider naloxone distribution - its status as a prescription drug approved for use by injection. Changing this is a torturous regulatory process. In the short term, though, lawmakers can do a lot to get distribution going where it is needed. As of July of 2012, eight states had passed laws to clearly authorize or otherwise reduce legal barriers to the prescription of naloxone to drug users and other potential good Samaritans. That leaves 42 states where programs may have trouble operating out of concerns related to prescribing a drug for a lay person to administer. LawAtlas covers the law and has examples of the legislative approaches these states have taken.. One more thing: evidence that naloxone distribution looks to be cost-effective ought to motivate lawmakers to consider these programs.

TY - JOUR. T1 - Opiate antagonist facilitation of time-dependent memory processes. T2 - Dependence upon intact norepinephrine function. AU - Gallagher, Michela. AU - Rapp, Peter R.. AU - Fanelli, Richard J.. PY - 1985/11/18. Y1 - 1985/11/18. N2 - Post-training administration of opiate antagonists improves retention of recent learning in laboratory animals tested on a variety of tasks. We examined the possibility that this effect of opiate antagonist treatment might be due to release of brain norepinephrine (NE) function from opioid peptide inhibition. The behavioral testing procedure in these experiments consisted of one-trial passive avoidance conditioning. Rats received post-training treatments immediately after the training trial and retention was tested 24 h later. Lesions of the dorsal noradrenergic bundle (DNB) that were induced by 6-hydroxydopamine (6-OHDA) were found to prevent the memory enhancing effect of post-training naloxone administration. The memory enhancing effect of naloxone ...

Cost barriers to more widespread use of buprenorphine in the treatment of opioid addiction have begun to ease. Other obstacles, including the longstanding limit on how many patients a prescribing physician may treat at any one time, could take substantially longer to remove, and California addiction medicine specialist Matthew A. Torrington, MD, says he is learning to be patient.. These things take a lot longer than anybody hoped they would, says Torrington, who will deliver a keynote presentation on the past, present and future of buprenorphine at next months Addiction Professional Academy on opioid addiction and pain management in Orange County, Calif. Only the old and the wise realize how long it takes. The young and inexperienced, like myself, think everything is going to happen overnight.. Maintaining the view that the glass is half full, Torrington points out that many more patients have access to medication-assisted treatment now that methadone is no longer the sole medication ...

SEATTLE -- Opioid-induced constipation in advanced cancer is relieved for more than half of patients within four hours by a subcutaneous injection of methylnaltrexone, researchers here reported.
The purpose of this study is to evaluate the efficacy of methylnaltrexone in relieving opioid-induced constipation in cancer patients at various stages
To understand trends in buprenorphine use, King and her co-authors used IQVIA Real World Longitudinal Prescription Data, a database that records prescription information for people across the United States. This tool allowed the researchers to see which patients were getting buprenorphine, how long they stayed on the medication, and who prescribed it for them-a primary care physician, a psychiatrist or addiction specialist, or (more rarely) another type of provider, such as a medical specialist, dentist, or pharmacist.. Understanding the source of buprenorphine prescriptions is a good indicator of access, King explains. Addiction specialists and psychiatrists were once the gatekeepers of medication-assisted treatment but can no longer keep up with demand, so theres been a movement to allow primary care providers to prescribe therapies such as buprenorphine. Being able to understand whether primary care doctors are prescribing buprenorphine and whether thats a viable path towards expanded ...

N2 - The δ-opioid antagonist H-Tyr-Tic-Phe-Phe-OH (TIPP-OH) or its C- terminal amide analogue was systematically modified topologically by substitution of each amino acid residue by all stereoisomers of the corresponding β-methyl amino acid. The potency and selectivity (δ-vs μ- and κ-opioid receptor) were evaluated by radioreceptor binding assays. Agonist or antagonist potency were assayed in the mouse vas deferens and in the guinea pig ileum. In the TIPP analogues containing L-β-methyl amino acids the influence on δ-receptor affinity and on 5-antagonist potency is limited, ...

Buprenorphine (also known as Subutex, or Suboxone when formulated with another drug, naloxone) is an effective treatment for opioid dependence. Treatment with buprenorphine has been shown to lead to reduced rates of heroin and prescription opioid use, as well as a reduction in risky behaviors that are associated with development of significant co-morbidities such as HIV or viral hepatitis infection.. To better understand the reasons for disengagement from buprenorphine treatment, researchers from BUSM and BUSPH examined patients treated at BMCs OBAT program between 2002 and 2014. The observational study followed more than 1,200 patients over 12 years with the goal of identifying patient-specific factors associated with retention in the treatment program for longer than one year. It specifically evaluated age, gender, race/ethnicity, education level, employment, infection with hepatitis C virus, co-morbid psychiatric conditions, and prior or current use of drugs or alcohol.. While the study ...

Pentazocine is an opiate antagonist and prevents or reverses the effects of opioids including respiratory depression, sedation and hypotension. Also, it can reverse the psychotomimetic and dysphoric effects of agonist-antagonists such as pentazocine. Pentazocine is an essentially pure narcotic antagonist, i.e., it does not possess the agonistic or morphine-like properties characteristic of other narcotic antagonists; Pentazocine does not produce respiratory depression, psychotomimetic effects or pupillary constriction. In the absence of narcotics or agonistic effects of other narcotic antagonists, it exhibits essentially no pharmacologic activity ...
