Sigma receptors bind several psychoactive substances, including certain opioids, but their endogenous ligands are not known.Naltrexone: Derivative of noroxymorphone that is the N-cyclopropylmethyl congener of NALOXONE. It is a narcotic antagonist that is effective orally, longer lasting and more potent than naloxone, and has been proposed for the treatment of heroin addiction. The FDA has approved naltrexone for the treatment of alcohol dependence.Analgesia, Patient-Controlled: Relief of PAIN, without loss of CONSCIOUSNESS, through ANALGESIC AGENTS administered by the patients. It has been used successfully to control POSTOPERATIVE PAIN, during OBSTETRIC LABOR, after BURNS, and in TERMINAL CARE.

Delta opioid receptors bind endorphins and enkephalins with approximately equal affinity and have less affinity for dynorphins.Meperidine: A narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. Prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration.Thebaine: A drug that is derived from opium, which contains from 0.3-1.5% thebaine depending on its origin. It produces strychnine-like convulsions rather than narcosis. It may be habit-forming and is a controlled substance (opiate) listed in the U.S. Code of Federal Regulations, Title 21 Part 1308.12 (1985).

They are large peptides derived from the PRO-OPIOMELANOCORTIN precursor. The known members of this group are alpha-, beta-, and gamma-endorphin. The term endorphin is also sometimes used to refer to all opioid peptides, but the narrower sense is used here; OPIOID PEPTIDES is used for the broader group.Methadone: A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1082-3)Receptors, Opioid, kappa: A class of opioid receptors recognized by its pharmacological profile. Kappa opioid receptors bind dynorphins with a higher affinity than endorphins which are themselves preferred to enkephalins.Injections, Subcutaneous: Forceful administration under the skin of liquid medication, nutrient, or other fluid through a hollow needle piercing the skin.Spinal Cord: A cylindrical column of tissue that lies within the vertebral canal.

It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use.

Effect of morphine and naloxone on priming-induced audiogenic seizures in BALB/c mice. (1/3881)

1 Morphine (1-200 mg/kg s.c.) reduced the incidence and prolonged the latency of priming-induced audiogenic siezures in a dose-dependent manner. 2 This effect was reversed by naloxone (1 and 2 mg/kg) although naloxone was itself inactive. 3 This priming-induces seizure model may be useful in the study of tolerance and physical dependence.  (+info)

Spinal antinociceptive synergism between morphine and clonidine persists in mice made acutely or chronically tolerant to morphine. (2/3881)

Morphine (Mor) tolerance has been attributed to a reduction of opioid-adrenergic antinociceptive synergy at the spinal level. The present experiments tested the interaction of intrathecally (i.t.) administered Mor-clonidine (Clon) combinations in mice made acutely or chronically tolerant to Mor. ICR mice were pretreated with Mor either acutely (40 nmol i.t., 8 h; 100 mg/kg s.c., 4 h) or chronically (3 mg/kg s.c. every 6 h days 1 and 2; 5 mg/kg s.c. every 6 h days 3 and 4). Antinociception was detected via the hot water (52.5 degrees C) tail-flick test. After the tail-flick latencies returned to baseline levels, dose-response curves were generated to Mor, Clon, and Mor-Clon combinations in tolerant and control mice. Development of tolerance was confirmed by significant rightward shifts of the Mor dose-response curves in tolerant mice compared with controls. Isobolographic analysis was conducted; the experimental combined ED50 values were compared statistically against their respective theoretical additive ED50 values. In all Mor-pretreated groups, the combination of Mor and Clon resulted in significant leftward shifts in the dose-response curves compared with those of each agonist administered separately. In all tolerant and control groups, the combination of Mor and Clon produced an ED50 value significantly less than the corresponding theoretical additive ED50 value. Mor and Clon synergized in Mor-tolerant as well as in control mice. Spinally administered adrenergic/opioid synergistic combinations may be effective therapeutic strategies to manage pain in patients apparently tolerant to the analgesic effects of Mor.  (+info)

Discriminative stimulus effects of naltrexone after a single dose of morphine in the rat. (3/3881)

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)

Extinction of responding maintained by timeout from avoidance. (4/3881)

The resistance to extinction of lever pressing maintained by timeout from avoidance was examined. Rats were trained under a concurrent schedule in which responses on one lever postponed shock on a free-operant avoidance (Sidman) schedule (response-shock interval = 30 s) and responses on another lever produced 2 min of signaled timeout from avoidance on a variable-ratio 15 schedule. Following extended training (106 to 363 2-hr sessions), two experiments were conducted. In Experiment 1 two different methods of extinction were compared. In one session, all shocks were omitted, and there was some weakening of avoidance but little change in timeout responding. In another session, responding on the timeout lever was ineffective, and under these conditions timeout responding showed rapid extinction. The within-session patterns produced by extinction manipulations were different than the effects of drugs such as morphine, which also reduces timeout responding. In Experiment 2 shock was omitted for many consecutive sessions. Response rates on the avoidance lever declined relatively rapidly, with noticeable reductions within 5 to 10 sessions. Extinction of the timeout lever response was much slower than extinction of avoidance in all 4 rats, and 2 rats continued responding at baseline levels for more than 20 extinction sessions. These results show that lever pressing maintained by negative reinforcement can be highly resistant to extinction. The persistence of responding on the timeout lever after avoidance extinction is not readily explained by current theories.  (+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. (5/3881)

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)

Presynaptic inhibition of GABA(B)-mediated synaptic potentials in the ventral tegmental area during morphine withdrawal. (6/3881)

Opioids increase the firing of dopamine cells in the ventral tegmental area by presynaptic inhibition of GABA release. This report describes an acute presynaptic inhibition of GABAB-mediated IPSPs by mu- and kappa-opioid receptors and the effects of withdrawal from chronic morphine treatment on the release of GABA at this synapse. In slices taken from morphine-treated guinea pigs after washing out the morphine (withdrawn slices), a low concentration of a mu receptor agonist increased, rather than decreased, the amplitude of the GABAB IPSP. In withdrawn slices, after blocking A1-adenosine receptors with 8-cyclopentyl-1, 3-dipropylxantine, mu-opioid receptor activation inhibited the IPSP at all concentrations and increased the maximal inhibition. In addition, during withdrawal, there was a tonic increase in adenosine tone that was further increased by forskolin or D1-dopamine receptor activation, suggesting that metabolism of cAMP was the source of adenosine. The results indicate that during acute morphine withdrawal, there was an upregulation of the basal level of an opioid-sensitive adenylyl cyclase. Inhibition of this basal activity by opioids had two effects. First, a decrease in the formation of cAMP that decreased adenosine tone. This effect predominated at low mu receptor occupancy and increased the amplitude of the IPSP. Higher agonist concentrations inhibited transmitter release by both kinase-dependent and -independent pathways. This study indicates that the consequences of the morphine-induced upregulation of the cAMP cascade on synaptic transmission are dependent on the makeup of receptors and second messenger pathways present on any given terminal.  (+info)

Effects and interactions of opioids on plasma exudation induced by cigarette smoke in guinea pig bronchi. (7/3881)

The effects of opioids on cigarette smoke-induced plasma exudation were investigated in vivo in the main bronchi of anesthetized guinea pigs, with Evans blue dye as a plasma marker. Acute inhalation of cigarette smoke increased plasma exudation by 216% above air control values. Morphine, 0.1-10 mg/kg but not 30 mg/kg, inhibited the exudation but had no significant effect on substance P-induced exudation. Both 10 and 30 mg/kg of morphine increased exudation in air control animals, an effect inhibited by antihistamines but not by a tachykinin neurokinin type 1-receptor antagonist. Naloxone inhibited all morphine responses. Cigarette smoke-induced plasma exudation was inhibited by a mu-opioid-receptor agonist (DAMGO) but not by agonists at delta (DPDPE)- or kappa (U-50488H)-receptors. None of these agonists affected exudation in air control animals. DPDPE prevented the inhibition by DAMGO of cigarette smoke-induced plasma exudation, and the combination of DAMGO and DPDPE increased exudation in air control animals. Prevention of inhibition and the combination-induced increase were inhibited by antihistamines or the mast cell-stabilizing drug sodium cromoglycate. U-50488H did not alter the response to either DAMGO or DPDPE. We conclude that, in guinea pig main bronchi in vivo, mu-opioid-receptor agonists inhibit cigarette smoke-induced plasma exudation via a prejunctional mechanism. Plasma exudation induced by mu- and delta-receptor interactions is due to endogenous histamine release from mast cells.  (+info)

Morphine preconditioning attenuates neutrophil activation in rat models of myocardial infarction. (8/3881)

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)

Plasma morphine concentration-time profiles and changes in PaCO2 were determined after morphine injection. After morphine injection, the end- tidal anesthetic dose was manipulated over the course of a 4-h observation period to account for the decline in plasma morphine concentration and to maintain an anesthetic level equivalent to 1.0 MAC isoflurane or halothane alone. Morphine decreased the MAC of halothane and isoflurane. The magnitude of MAC decrease was related to time after morphine injection and was ...
After inducing morphine tolerance in rats, the researchers tested the animals spinal cord responses to morphine, with or without resveratrol. The results showed significant enhancement of morphines effects in animals receiving resveratrol. In morphine-tolerant rats, the pain-relieving response to morphine was about 20 percent of normal. In rats receiving resveratrol, morphine responses were restored to about 60 percent of normal.. In preserving the pain-relieving effects of morphine, resveratrol appeared to work in two ways. It reversed the increase in expression of a type of neurotransmitter (N-methyl D-aspartate, or NMDA) receptors associated with morphine tolerance. Resveratrol also blocked the increase of inflammation-promoting substances, called cytokines, in rats with morphine tolerance.. The results add to other recent experimental evidence suggesting that resveratrol can maintain the pain-relieving effect of morphine. It also adds new information on how that effect may ...
Morphine administration during pregnancy causes several behavioral abnormalities in offspring animals. In the present study the effects of maternal morphine consumption on development of neural tube in Wistar rats (250-300 g) were investigated. Female rats (n = 8 were crossed with male rats and pregnant ones were treated with oral morphine (0.01, 0.05 and 0.1 mg/ml of water) until the 10th day of pregnancy. On the day 10, the animals were anesthetized by diethyle ether and the embryos were taken out surgically. The embryos were fixed in formaline 10% for a week and then cross sectional procedure performed. The sections were stained with H&E. The results showed that: administration of morphine resulted in severe reduction in neural tube development in embryos. Morphine at a dose of 0.01 mg/ml showed the maximum effect. In conclusion, it is clear that morphine consumption in pregnant rats resulted in delay in neural tube development that may be true in humans.
Morphine is a strong analgesic drug. Apart from that, morphine gives an intense, intoxicating effect. This is why it’s used for both medical and recreational purposes. Morphine is made from opium; the dried sap of the poppy plant. Opium contains a combination of opiates, including morphine.  Morphine and heroin are closely related, as morphine can be made into heroin. First, morphine is extracted from opium, followed by a chemical reaction that turns it into heroin. Therefore, heroin has a very similar effect to morphine. The main difference is that heroin passes the blood-brain barrier more easily, resulting in it kicking in faster than morphine does. In the Netherlands, morphine isn’t often used in a recreational context. However, in America, the situation is completely different. In this article, you can read about the history, usage, biochemistry and the risks of recreational use of morphine. We also discuss the mafia-like role that the pharmaceutic industry plays when it comes to
Introduction Morphine is the most effective pain-relieving drug, but it can cause unwanted side effects. Direct neuraxial administration of morphine to spinal cord not only can provide effective, reliable pain relief but also can prevent the development of supraspinal side effects. However, repeated neuraxial administration of morphine may still lead to morphine tolerance. Methods To better understand the mechanism that causes morphine tolerance, we induced tolerance in rats at the spinal cord level by giving them twice-daily injections of morphine (20 µg/10 µL) for 4 days. We confirmed tolerance by measuring paw withdrawal latencies and maximal possible analgesic effect of morphine on day 5. We then carried out phosphoproteomic analysis to investigate the global phosphorylation of spinal proteins associated with morphine tolerance. Finally, pull-down assays were used to identify phosphorylated types and sites of 14-3-3 proteins, and bioinformatics was applied to predict biological networks impacted

Due to the potential desensitization of opioid receptors the dose of morphine and nalmefene were increased stepwise (5 10 and 15 mg/kg s.c. for every two weeks). For drug combination the nalmefene dose was one-tenth of the morphine dose because this ratio is generally considered to result in a complete antagonism of antinociceptive effects of morphine [17]. The body weight of the Specnuezhenide animals and the two perpendicular diameters (a and b) were recorded every 3 days. Tumor volume (V) was calculated according to the following formula: V = (a*b*b)/2 [18]. ...
Hypothesis:. Oral morphine will produce more reliable peak plasma morphine concentrations and more reliable analgesia than codeine, which is currently the drug of choice.. Background:. Codeine is the most commonly used oral opiate for analgesia in children. Codeine is a pro-drug that requires activation by the isozyme CYP2D6. Genetically determined variations in the activity of CYP2D6 can result in inappropriately low analgesic efficacy due to inadequate conversion of the drug in poor-metabolizers and conversely, adverse reactions such as respiratory depression and death in ultra-metabolizers. In some ethnic groups as many as 40% of patients may be susceptible to concentration-dependent toxicity from greater than expected metabolism of codeine to morphine. We hypothesize that oral morphine is a feasible and safe alternative to codeine. The primary aim of this study is to define and trial an appropriate dose of morphine to provide children with effective and reliable perioperative analgesia ...

Problem statement: The present study was performed to determine the effect of Intracerebroventricular (ICV) administration of W-7, a specific calmodulin inhibitor, on the analgesic effect and development of tolerance to antinociceptive effect of acute and chronic morphine administration respectively. Approach: This study was carried out on male wistar rats, weighing 200-250 g. For acute experimental protocol, Morphine was injected intraperitonealy in a single dose (5 mg kg-1). For chronic experimental protocol, Morphine was administered daily (15 mg kg-1 for 8 days). The threshold to thermal nociceptive stimuli was measured by tail-flick test. In acute and chronic experiments, W-7 (0.25, 0.5 and 1 μmol/rat) was injected through ICV at different paradigms. Maximal Possible Effect percentage (MPE%) was considered as analgesia index. Results: Our result showed that W-7 (0.25, 0.5 and 1 μmol/rat) injections before acute morphine administration significantly reduced the analgesic effect of
Generic Morphine Sulphate MAGNUS MR 30mg/2ml / Amps Therapeutic Class:Narcotic analgesic Composition:Magnus MR 2ml vial containing morphine sulphate 30 mg/2mlDescription:Morphine applies an agonist effect at saturable opioid receptors in the CNS and other tissues & acts as opioid analgesic. Morphine is an analgesic drug used to treat acute and chronic pain. Obesity is frequently associated with pain of various origins (e.g. arthritis, fibromyalgia, cancer), which increases the need for analgesic drugs. Obesity changes drug pharmacokinetics, and for certain drugs, specific modalities of prescription have been proposed for obese patients. However, scant data are available regarding the pharmacokinetics and pharmacodynamics of morphine in obesity.

Diabetes is one of the most common diseases in all societies including Iran. One of its important complications is the neuropathic pain, which can be relieved by opioid drugs such as morphine. Opioid therapy is restricted due to development of tolerance and physical or mental dependence. In this study, the effect of diabetes on morphine analgesia and development of morphine tolerance and dependence was investigated. Experimental diabetes was induced by alloxan (120 mg/kg, s.c.) in rats. Morphine sulfate (7 mg/kg, i.p.) application for 5 days developed tolerance in animals. On 5th day, 30 min after the injection of morphine, the acute and chronic pain was evaluated in diabetic and non-diabetic animals using hot plate and formalin test. In addition, withdrawal signs (jumping, chewing, urine and feces) were recorded for ten minutes using naloxone (2 mg/kg, s.c.). The results showed that the anti-nociceptive effect of morphine for acute pain markedly reduced, but slightly enhanced for chronic pain model.

Morphine is an extremely strong opiate analgesic drug and is the most important active agent in opium and the prototypical opioid.. It is also a natural endocrine product in humans and other animals. Like other opioids, diacetylmorphine or commonly know as heroin, morphine targets directly the central nervous system (CNS) to alleviate pain, and at synapses of the nucleus accumbens in particular.. Morphine is extremely addictive when compared to other substances; physical, tolerance and psychological dependences build up very rapidly. Withdrawal from morphine causes nausea, tearing, yawning, chills, and sweating lasting up to three days. Morphine crosses the placental barrier, and babies born to morphine-using mothers go through withdrawal.. Addictive drugs, for instance Morphine trigger the brains reward systems.. The promise of reward is very powerful, causing the individual to yearn for Morphine and to center his or her attention activities on the taking of Morphine. The capacity to ...
OUTLINE: This is a multicenter study.. Patients complete a pain questionnaire over 1 week before undergoing radiofrequency ablation (RFA). Patients also complete questionnaires about pain, physical performance, quality of life (QOL), and anxiety at baseline.. Bone metastases are removed by radiofrequency ablation (RFA). After surgery, patients receive acetaminophen and patient-controlled analgesic (PCA) morphine sulfate. PCA morphine sulfate continues with a dose increase of 50% bolus every 24 hours. Patients with maximum pain less than or equal to that at inclusion receive standard morphine sulfate therapy instead.. Data concerning the total dose of PCA morphine sulfate; minimum, average, and maximum pain intensity; side effects and complications of RFA; and total dose of morphine sulfate (or equivalent) is collected daily.. Pain is assessed at 4 and 8 weeks after RFA. Patients complete follow-up questionnaires about physical performance, QOL, and anxiety at 12 weeks. Patients also undergo a CT ...
Methods Effect of morphine treatment on acute pancreatitis in caerulein, L-arginine and ethanol-palmitoleic acid models was evaluated after induction of the disease. Inflammatory response, gut permeability and bacterial translocation were compared. Experiments were repeated in mu (µ) opioid receptor knockout mice (MORKO) and in wild-type mice in the presence of opioid receptor antagonist naltrexone to evaluate the role of µ-opioid receptors in morphines effect on acute pancreatitis. Effect of morphine treatment on pathways activated during pancreatic regeneration like sonic Hedgehog and activation of embryonic transcription factors like pdx-1 and ptf-1 were measured by immunofluorescence and quantitative PCR. ...
Thesis, English, COMPARATIVE STUDY BETWEEN THE EFFICACY OF TRANSDERMAL FENTANYL PATCHES INTRATHECAL MORPHINE AND INTRAMUSCULAR MORPHINE IN THE RELIEF OF ACUTE POSTOPERATIVE PAIN AFTER MAJOR ONCOLOGICAL SURGERY for Othman Ahmed Hassan
The present study was designed to determine whether the p53 tumor-suppressor protein is involved in the development of antinociceptive tolerance to morphine. When the doses of morphine (mg/kg per injection) were subcutaneously given into mice as pretreatment twice daily for 2 days (first day (30) and second day (60)), intrathecal (i.t.) administration of morphine (0.1nmol) was inactive due to antinociceptive tolerance in the 0.5% formalin test on the third day. Tolerance to i.t. morphine was significantly suppressed by i.t. injection of pifithrin-alpha (1 and 10nmol), an inhibitor of p53 activation, benzyloxycarbonyl-Val-Ala-Asp(OMe)-fluoromethylketone (Z-VAD-fmk) (1 and 10nmol), a non-selective caspase inhibitor, or N(G)-nitro-l-arginine methyl ester (l-NAME) (2 and 20nmol), a non-selective inhibitor of nitric oxide synthase, 5min before each morphine treatment during the induction, with none given on the test day. Moreover, p53 expression in the spinal cord had increased significantly 14h ...
Several literature reports indicate that morphine administered subcutaneously during the early gestational period in mice and hamsters produced neurological, soft tissue and skeletal abnormalities. With one exception, the effects that have been reported were following doses that were maternally toxic and the abnormalities noted were characteristic of those observed when maternal toxicity is present. In one study, following subcutaneous infusion of doses greater than or equal to 0.15 mg/kg to mice, exencephaly, hydronephrosis, intestinal hemorrhage, split supraoccipital, malformed sternebrae, and malformed xiphoid were noted in the absence of maternal toxicity. In the hamster, morphine sulfate given subcutaneously on gestation day 8 produced exencephaly and cranioschisis. In rats treated with subcutaneous infusions of morphine during the period of organogenesis, no teratogenicity was observed. No maternal toxicity was observed in this study, however, increased mortality and growth retardation ...

States of abnormal pain induced by injuries to peripheral nerves share common features with opioid antinociceptive tolerance including mechanical and thermal hypersensitivity. Sustained administration of morphine in humans and in animals induces a state of abnormal pain (i.e., hyperalgesia) and may be associated with the development opioid antinociceptive tolerance. Persistent neuropathic pain states and opioid induced abnormal pain require descending facilitation arising from the rostral ventromedial medulla (RVM). Cholecystokinin (CCK), a pronociceptive peptide, may be up-regulated following opioid treatment and nerve injury in the brain and spinal cord. Therefore, it is hypothesized that CCK in the RVM may be up-regulated by sustained opioid administration and my consequently drive descending pain facilitatory mechanisms to produce hypersensitivity and antinociceptive tolerance.Acute systemic morphine administration produced a potentiation of CCK release in the RVM as measured using ...

AU - Moshé, Solomon L.. AU - Vathy, Ilona. PY - 2000/6/30. Y1 - 2000/6/30. N2 - The present study examined the effects of prenatal morphine exposure on NMDA-dependent seizure susceptibility in the entorhinal cortex (EC), and on activity-dependent synaptic plasticity at Schaffer collateral and perforant path synapses in the hippocampus. During perfusion with Mg2+-free ACSF, an enhancement of epileptiform discharges was found in the EC of slices from prenatally morphine-exposed male rats. A submaximal tetanic stimulation (2x50 Hz/1 s) in control slices elicited LTP at the Schaffer collateral-CA1 synapses, but neither LTP nor LTD was evoked at the perforant path-DG synapses. In slices from prenatally morphine-exposed adult male rats, long-term potentiation of synaptic transmission was not observed ...
exon 3 (mE3M mice), while the other two selectively truncated C-terminal tails encoded by either exon 4 (mE4M mice) or exon 7 (mE7M mice). Studies of these mice revealed divergent roles for the C termini in morphine-induced behaviors, highlighting the importance of C-terminal variants in complex morphine actions. In mE7M-B6 mice, the exon 7-associated truncation diminished morphine tolerance and reward without altering physical dependence, whereas the exon 4-associated truncation in mE4M-B6 mice facilitated morphine tolerance and reduced morphine dependence without affecting morphine reward. mE7M-B6 mutant mice lost morphine-induced receptor desensitization in the brain stem and hypothalamus, consistent with exon 7 involvement in morphine tolerance. In cell-based studies, exon 7-associated variants shifted the bias of several mu opioids toward β-arrestin 2 over G protein activation compared with the exon 4-associated variant, suggesting an interaction of exon 7-associated C-terminal tails with ...
Scientists studying induced nerve injury in rodents have found that the analgesic effects of morphine can decline over time. When morphine is used in combination with carbamazepine, which prevents epileptic seizures, this loss of drug efficacy may be reversed.. There has been mixed efficacy in general using opioids to treat neuropathic pain. The pain relief brought about by morphine can diminish over time. In this study, when carbamazepine was added to the morphine regimen, opioid induced hyperalgesia was reversed. As reported in PLOS ONE, the combination of drugs administered to rodents showed that "the dampening of the analgesic effects of morphine on neuropathic pain behavior in vivo can be countered with the addition of CBZ.".

N2 - Introduction: Opioid withdrawal syndrome is a critical component of opioid abuse and consists of a wide array of symptoms including increases in pain sensitivity (hyperalgesia). A reliable preclinical model of hyperalgesia during opioid withdrawal is needed to evaluate possible interventions to alleviate withdrawal. The following study describes a method for assessing increases in thermal sensitivity on the hotplate in a mouse model of spontaneous morphine withdrawal. Methods: C57BL/6J mice received 5.5. days of 30, 56, or 100. mg/kg morphine or saline (s.c., twice daily). In Experiment I, thermal sensitivity data were collected at baseline and at 8, 24, 32, 48. h and 1. week following the final injection. Thermal sensitivity was assessed by examining latency to respond on a hotplate across a range of temperatures (50, 52, ...
In this study we used viral-mediated gene transfer and epitope tagging to examine the effects of acute opiate administration on the localization of wild-type and mutant opioid receptors in physiologically relevant nucleus accumbens neurons in vivo. Under the conditions used, recombinant receptors were expressed in widely separated neurons, allowing us to resolve individual receptor-expressing cell bodies and associated processes by light microscopy. We also used immunoelectron microscopy to examine at higher resolution the effects of morphine on the density and distribution of endogenously expressed MOR within specific subcellular compartments in the same population of neurons.. Our studies of receptor localization in cell bodies support previous observations (namely, that acute morphine administration fails to induce detectable internalization in MOR in this compartment; Sternini et al., 1996; Keith et al., 1998; Trafton et al., 2000; He et al., 2002). The present results also indicate that the ...
Morphine-induced hyperalgesia (MIH) is a severe adverse effect accompanying repeated morphine treatment, causing a paradoxical decrease in nociceptive threshold. Previous reports associated MIH with a decreased expression of the Cl- extruder KCC2 in the superficial dorsal horn (SDH) of the spinal cord, weakening spinal GABAA/glycine-mediated postsynaptic inhibition. Here, we tested whether the administration of small molecules enhancing KCC2, CLP257 and its pro-drug CLP290, may counteract MIH. MIH was typically expressed within 6-8 days of morphine treatment. Morphine-treated rats exhibited decreased withdrawal threshold to mechanical stimulation and increased vocalizing behavior to subcutaneous injections. Chloride extrusion was impaired in SDH neurons measured as a depolarizing shift in E GABA under Cl- load. Delivering CLP257 to spinal cord slices obtained from morphine-treated rats was sufficient to restore Cl- extrusion capacity in SDH neurons. In vivo co-treatment with morphine and oral ...
The effects described below are common to all morphine-containing products.. Central Nervous System. The principal actions of therapeutic value of morphine are analgesia and sedation (i.e., sleepiness and anxiolysis).. The precise mechanism of the analgesic action is unknown. However, specific CNS opiate receptors and endogenous compounds with morphine-like activity have been identified throughout the brain and spinal cord and are likely to play a role in the expression of analgesic effects.. Morphine produces respiratory depression by direct action on brain stem respiratory centers. The mechanism of respiratory depression involves a reduction in the responsiveness of the brain stem respiratory centers to increases in carbon dioxide tension, and to electrical stimulation.. Morphine depresses the cough reflex by direct effect on the cough center in the medulla. Antitussive effects may occur with doses lower than those usually required for analgesia. Morphine causes miosis, even in total darkness. ...
FDA remains committed to taking enforcement actions against unapproved drugs in an effort to ensure that drugs used by patients are safe and effective, while at the same time ensuring that such actions do not impose an undue burden on patients. Currently, there are no approved morphine sulfate oral solution 20 mg/ml products being marketed in the U.S. FDA has heard from the pain management community that the impending market removal of unapproved morphine sulfate oral solution 20 mg/ml products announced in the Warning Letters would impose unacceptable hardship on palliative care patients, their families and caregivers. In light of this information, FDA will extend the enforcement discretion set forth in the Warning Letters to ensure that palliative care patients have access to morphine sulfate oral solution 20 mg/ml. The period of enforcement discretion will be extended until 180 days after any firm receives approval for a morphine sulfate oral solution 20 mg/ml product or if FDA determines ...
Morphine is an alkaloid from the plant extracts of opium poppy. Although morphine is highly effective for the treatment of pain, it is also known to be intensely addictive. We now know that the most important brain-reward circuit involves dopamine (DA) -containing neurons in the ventral tegmental area (VTA) of the midbrain and their target areas in the limbic forebrain, in particular, the nucleus accumbens (NAc) and frontal regions of cerebral cortex. Morphine can cause indirect excitation of VTA dopamine neurons by reducing inhibitory synaptic transmission mediated by GABAergic neurons. The chronic use of morphine is characterized by adaptive changes in neurons and neuronal communication; such adaptations (e.g., superactivation of adenylyl cyclase) must underlie altered behaviour associated with morphine dependence and withdrawal syndrome, as well as drug-induced craving and relapse to drug use ...
Medical management of newborn infants often necessitates recurrent painful procedures, which may alter nociceptive pathways during a critical developmental period and adversely effect neuropsychological outcomes. To mitigate the effects of repeated painful stimuli, opioid administration for peri-procedural analgesia and ICU (intensive care unit) sedation is common in the NICU (neonatal intensive care unit). A growing body of basic and animal evidence suggests potential long-term harm associated with neonatal opioid therapy. Morphine increases apoptosis in human microglial cells, and animal studies demonstrate long-term changes in behavior, brain function, and spatial recognition memory following morphine exposure. This comprehensive review examines existing preclinical and clinical evidence on the long-term impacts of neonatal pain and opioid therapy.
In December 1804, Friedrich Sertürner first discovered morphine as the first alkaloid derived from the opium poppy in Paderborn, Germany. Sertürner named the drug as morphium after the Greek god Morpheus because it provides a feeling of sleepiness.. He administered the drug to himself, along with three young boys, three dogs, and a mouse. Unfortunately, he and the boys almost died because of morphine. In 1817, the Sertürner and Company first marketed morphine to the general public as a pain reliever. They claimed that the drug can even cure opium and alcohol addiction.. However, in 1822 morphine was first used a poison in France when Dr. Edme Castaing was convicted of using the drug to his patient.. Five years later, in 1827, commercial productions of morphine become rampant in Darmstadt, Germany under the pharmaceutical company Merck. Sales from morphine contributed a lot to the early growth of their company.. On the other hand, in 1850, Alexander Wood experimented with the drug and injected ...

Hi ive had fibro for 5 yrs now and been on various meds, currently codeine, pregablin, paracetamol, sertraline. Im keen to try morphine as been on other pain relief for yrs now and feel like its not working anymore. Ive just changed drs as my old drs was bad for being seen and when i asked about morphine i was told id have to be referred to a pain clinic and that it would be their decision if i had any kind of morphine although the dr said morphine isnt very good for fibro yet ive heard of others being given it no issues. I suffer horrible muscle spasms in my back and legs and my current meds just arnt helping. Im scared if i mention morphine that my dr will think im some druggy. Dont know what to do or anything....

Additive Synthesizers are rare enough that they exist in an atmosphere of mystique, rumour and fear. Some say that Additive Synthesis is so complicated that it makes FM synthesis appear to have the engineering complexity of a spoon. Fortunately the reality is a lot less scary, Morphine is only slightly more complex to master than a spoon and you will be feeding yourself in no time. Probably the best analogy is to consider Morphine a multi-sampler that can generate its own synthetic samples. So how does Morphine do this? Any sound can be represented by an infinite series of harmonics (sine waves) that vary constantly in amplitude and phase. Morphine captures this harmonic variation as a series of snapshots, just like the still frames in a movie and then by playing back this harmonic movie, in real-time, almost any sound can be re/created in synthetic form. So there you have synthesis in Morphine, not so scary. The hardest part will be learning the jargon in this manual. If Morphine is a ...
I was surprised by all the heavy-duty drugs I was given this week. This is the kind of stuff you read about in newspapers - morphine and cocaine! My previous history as a drug user is easily told. I never tried any heavy recreational drugs and the few times - twice perhaps - that I smoked marijuana, I really hated it. Since those bad experiences some 25 years ago, its been clear to me that drugs are scary and that my mind doesnt need additional excitement. My mind creates sufficient excitement on its own.. Now let me tell you about Mr. Morphine. Mr. Morphine is a guy who suddenly appears after Ive had 12.5 milliliters of that clear, opium-based, liquid my doctor gave me.

Morphine Sulfate 120 mg Actavis, This medication is used to help relieve moderate to severe pain. Morphine belongs to a class of drugs known as opioid (narcotic) analgesics. It works in the brain to change how your body feels and responds to pain.
Morphine sulfate in doses of 90 to 150 micrograms/3 microliters evoke a prominent behavioral syndrome characterized by 1) periodic bouts of spontaneous agitation during which the rat scratches and bites at the skin of the caudal dermatomes and 2) vigorous agitation, vocalization and coordinated efforts to bite and escape evoked by a light tactile stimulus applied to the flank, suggestive of a pain state (allodynia). The phenomenon is not reversed by naltrexone or is it subject to tolerance. The ordering of activity of an opioid alkaloid related agent in producing this touch-evoked agitation is: noroxymorphone-3-glucuronide, morphine-3-glucuronide, morphine-3-ethereal sulfate, dihydromorphine, noroxymorphone dihydrate, hydromorphone, dihydrocodeine tartrate, morphine sulfate, dihydroisomorphine, morphine-HCl, 6-acetylmorphine, N-normorphine-HCl and (+)-morphine. The following agents were essentially without effect at the highest doses examined: 3,6-diacetylmorphine, N-normeperidine-HCl, ...

Next, the spinal pharmacology of intravenously administered morphine antinociception was examined. Animals received 2.5 mg/kg morphine administered intravenously, followed in 20 min by intrathecal injection of saline or a drug, and followed in 15 min by a second intrathecal injection of saline or a greater dose of the same drug. By this method, two doses of drug were studied in each experiment. Drugs studied were the [Greek small letter alpha]2-adrenergicantagonist idazoxan (2.5-45.0 [micro sign]g), the muscarinic antagonist atropine (5 - 40 [micro sign]g), the nonspecific NOS inhibitor NG-monomethyl-L-arginine(NMMA; 2-36 [micro sign]g), the neuronal NOS specific inhibitor 1-(2-trifluoromethylphenyl) imidazole (TRIM; 2.5 - 45.0 [micro sign]g), and the NO scavenger 2-(4-Carboxyphenyl)-4,4,5,5-tetramethyl-imidazoline-1-oxyl-3-oxide potassium (PTIO; 2.5 - 45.0 [micro sign]g). To study the interaction between intravenously administered morphine and increased spinal availability of NO, other animals, ...
Morphine is an opiate painkiller that was first described in the 16th century by Swiss Physician Paracelsus. Although not directly what we think of today as morphine, as this was not synthesized until the early 1800s, Paracelsus described the substance as a potent drug that could help to alleviate pain, but also suggested that it only be used sparingly.. It is interesting because we often times think of the notion of addiction as a modern understanding, but even back in the 16th century individuals were aware of the potential for abuse of opiates, and because of this Paracelsus suggested sparing usage, and that the substance be only used for medical applications.. In 1817 the first known morphine product became available for public consumption and with this introduction to the general public, morphine began to exhibit its addictive properties. Many individuals fell into morphine addiction, as they were totally unaware that it could create addiction, and very quickly it was discovered that the ...
4.4. Ventilatory Responses to Hypoxic Challenges in Morphine-Treated Rats- Episode H1. H1 elicited markedly smaller increases in fr in MOR rats although resting fr was not diminished. As such, morphine elicited latent effects on systems including those within the carotid bodies that drive the hypoxic responses. Our data are consistent with evidence that the negative effects of opioids in humans may be latent since the morphine metabolite, M6G, does not affect resting ventilatory parameters whereas it substantially blunts the ventilatory response to hypercapnic challenge [5]. Since morphine did not markedly blunt the increase in Vt during H1, it is evident that it did not negatively affect neural drive to the chest muscles or diaphragm. This is supported by the finding that Ti in MOR rats (elevated immediately prior to exposure to hypoxia) decreased substantially during H1. Taken together, our data support the concept that morphine affected brainstem centers responsible for generating breathing ...

Rationale: Opioids are commonly used to relieve dyspnea, but clinical data are mixed and practice varies widely. Objectives: Evaluate the effect of morphine on dyspnea and ventilatory drive under well-controlled laboratory conditions. Methods: Six healthy volunteers received morphine (0.07 mg/kg) and placebo intravenously on separate days (randomized, blinded). We measured two responses to a CO2 stimulus: (1) perceptual response (breathing discomfort; described by subjects as "air hunger") induced by increasing partial pressure of end-tidal carbon dioxide (PetCO2) during restricted ventilation, measured with a visual analog scale (range, "neutral" to "intolerable"); and (2) ventilatory response, measured in separate trials during unrestricted breathing. Measurements and Main Results: We determined the PetCO2 that produced a 60% breathing discomfort rating in each subject before morphine (median, 8.5 mm Hg above resting PetCO2). At the same PetCO2 after morphine administration, median breathing ...
Purpose: The WHO guidelines on cancer pain management recommend a sequential three-step analgesic ladder. However, conclusive data are lacking as to whether moderate pain should be treated with either step II weak opioids or low-dose step III strong opioids. Patients and Methods: In a multicenter, 28-day, open-label randomized controlled study, adults with moderate cancer pain were assigned to receive either a weak opioid or low-dose morphine. The primary outcome was the number of responder patients, defined as patientswith a 20% reduction in pain intensity on the numerical rating scale. Results: A total of 240 patients with cancer (118 in the low-dose morphine and 122 in the weak-opioid group) were included in the study. The primary outcome occurred in 88.2% of the low-dose morphine and in 57.7% of the weak-opioid group (odds risk, 6.18; 95% CI, 3.12 to 12.24; P,001). The percentage of responder patients was higher in the low-dose morphine group, as early as at 1 week. Clinically meaningful (, ...
Vapors of Morphine is an American rock band founded in 2009 by the surviving members of the alternative rock band Morphine Dana Colley and Jerome Deupree and blues guitarist Jeremy Lyons. The band was officially formed in 2009, when Dana Colley was asked to bring a group to Nel Nome Del Rock Festival in Palestrina, Italy. Ten years earlier, Morphines frontman Mark Sandman had suddenly died of a massive heart attack while performing in that venue. After some deliberation, Colley invited Jeremy Lyons to sing and play the 2-string slide bass, along with drummer Jerome Deupree. Lyons asked a friend to build a 2-string bass for him and started learning the Morphine repertoire. The process wasnt easy as Lyons had to master a new instrument while singing below his natural voice range. In the beginning, they couldnt agree on a name, and they alternated between "Members of Morphine & Jeremy Lyons" and the "Elastic Waste Band," which eventually morphed into "The Ever Expanding Elastic Waste Band". ...

  • To test the hypothesis that dopamine is an essential mediator of various opiate-induced responses, we administered morphine to mice unable to synthesize dopamine. (nature.com)
  • We found that dopamine-deficient mice are unable to mount a normal locomotor response to morphine, but a small dopamine-independent increase in locomotion remains. (nature.com)
  • In contrast, dopamine-deficient mice display a robust conditioned place preference for morphine when given either caffeine or l -dihydroxyphenylalanine (a dopamine precursor that restores dopamine throughout the brain) during the testing phases. (nature.com)
  • Together, these data demonstrate that dopamine is a crucial component of morphine-induced locomotion, dopamine may contribute to morphine analgesia, but that dopamine is not required for morphine-induced reward as measured by conditioned place preference. (nature.com)
