Sublingual Versus Swallowed Morphine: A Comparison.

The optimal route for immediate-release morphine administration is controversial. The known physical characteristics of morphine that allow absorption are counter to the unproven belief that sublingual morphine is absorbed more quickly.

Neurological excitation in a 6-week-old male infant after morphine overdose.

While respiratory depression is a known complication of morphine overdose, the neuro-excitatory side effect of the morphine metabolite morphine-3-glucuronide is less widely known. Here we report the case of an infant with neurological excitation after morphine overdose. The neuro-excitation in this infant was probably induced by an elevated morphine-3-glucuronide concentration. This article is protected by copyright. All rights reserved.

Pharmacokinetics of morphine in combination with dexmedetomidine and maropitant following intramuscular injection in dogs anaesthetized with halothane.

The purpose of this study was to evaluate the pharmacokinetics of morphine in combination with dexmedetomidine and maropitant injected intramuscularly in dogs under general anaesthesia. Eight healthy dogs weighing 25.76 ± 3.16 kg and 3.87 ± 1.64 years of age were used in a crossover study. Dogs were randomly allocated to four groups: (1) morphine 0.6 mg/kg; (2) morphine 0.3 mg/kg + dexmedetomidine 5 μg/kg; (3) morphine 0.3 mg/kg + maropitant 1 mg/kg; (4) morphine 0.2 mg/kg + dexmedetomi...

Magnesium and Ketamine Reduce Early Morphine Consumption After Open Bariatric Surgery: a Prospective Randomized Double-Blind Study.

Optimal pain management in bariatric patients is crucial for early recovery. This study aims to evaluate the effects of magnesium and ketamine combination on morphine consumption after open bariatric surgery (primary outcome), as well as on postoperative pain scores and occurrence of side effects.

Morphine induces the differentiation of T helper cells to Th2 effector cells via the PKC-θ-GATA3 pathway.

T help 2 (Th2) cell differentiation by morphine has been verified. However, the underlying mechanism of morphine induces Th2 cell differentiation remains elusive. The aim of the present study was to explore the possible basis of morphine induced Th2 cell differentiation.

Prolonged ethanol administration prevents the development of tolerance to morphine-induced respiratory depression.

Opioid users regularly consume other drugs such as alcohol (ethanol). Acute administration of ethanol can rapidly reverse tolerance to morphine-induced respiratory depression. However, alcohol consumption by opioid users is likely to occur over prolonged time periods. We have therefore sought to determine the effect of prolonged alcohol consumption on the development of tolerance to opioid respiratory depression.

A Randomized, Crossover Study on the Effect of Food on the Pharmacokinetic Characteristics of Morphine ARER (MorphaBond™ ER), an Abuse-Deterrent Formulation of Extended-Release Morphine.

Food can alter the pharmacokinetics of certain abuse-deterrent formulations. Morphine ARER is an oral abuse-deterrent formulation of ER morphine sulfate tablets formulated with physical and chemical properties that contribute to the abuse-deterrent aspects of the drug. This study compared the relative bioavailability of Morphine ARER in the presence and absence of food.

The influence of opioid dependence on salt consumption and related psychological parameters in mice and humans.

The consumption of dietary salt (NaCl) is controlled by neuronal pathways that are modulated by endogenous opioid signalling. The latter is disrupted by chronic use of exogenous opioid receptor agonists, such as morphine. Therefore, opioid dependence may influence salt consumption, which we investigated in two complimentary studies in humans and mice.

Possible involvement of nucleus accumbens D1-like dopamine receptors in the morphine-induced condition place preference in the offspring of morphine abstinent rats.

Previous researches demonstrated that genetics and environment are two essential factors to prone individuals to drug abuse. Our previous data showed that dopaminergic system changed in the offspring of morphine-abstinent rats. In the present study, we evaluated whether blocking the D1-like dopamine receptors (DR) in the nucleus accumbens (NAC) affect the rewarding effect of morphine in the offspring of morphine-abstinent rats.

Role of orexin-1 and -2 receptors within the nucleus accumbens in the acquisition of sensitization to morphine in rats.

It has been reported that orexins A and B are involved in the mediation of drug reward. In addition, the nucleus accumbens (NAc) has an important role in the development of morphine-conditioned place preference (CPP) and morphine sensitization. In the present study, we aimed to evaluate the role of orexin receptors within the NAc in morphine sensitization using CPP paradigm. Adult male Wistar rats were used and were bilaterally implanted by two cannulae in the NAc. The animals received intra-accumbal admini...

Profiling of morphine and codeine in urine after the ingestion of curry containing poppy seed as an evidence for opiates defence in Malaysia.

Consumption of curry containing poppy seeds has raised an issue concerning the opiate content in the urine that might exceed the cut-off value (300ng/mL). The main objective of this study was to examine the morphine and codeine contents in the urine of the consumers after partaking poppy seed-enriched curry in. The volunteers were asked to partake: (a) a single meal and their urines were collected within 24h, or (b) Two meals a day for three consecutive days and their urines were collected within 72h. Two d...

Rehabilitation in Nepal.

As a low-income country with a significant burden of disease and frequent natural disasters, the need for rehabilitation in Nepal is significant. Rehabilitation services currently available in Nepal are limited, but the government has recently adopted a 10-year action plan to address rehabilitation needs nationwide. Rehabilitation education and training is necessary to provide and retain adequate multidisciplinary rehabilitation providers for current and future needs in Nepal. The implementation of evidence...

Brain-blood ratio of morphine in heroin and morphine autopsy cases.

Brain tissue is a useful supplement to blood in postmortem investigations, but reference concentrations are scarce for many opioids. Heroin cases may be difficult to distinguish from morphine cases as heroin and its metabolites are rapidly degraded. We present concentrations from brain and blood and brain-blood ratios of 98 cases where morphine was quantified. These cases were grouped according to the cause of death: A: The compound was solely assumed to have caused a fatal intoxication. B: The compound pre...

Liproxstatin-1 attenuates morphine tolerance through inhibiting spinal ferroptosis-like cell death.

Morphine tolerance is a classic, challenging clinical issue. However, the mechanism underlying this phenomenon remains poorly understood. Recently, studies have shown that ferroptosis correlates with drug resistance. Therefore, this study investigated whether spinal cord ferroptosis contributes to morphine tolerance. C57BL/6 mice were continuously subcutaneously injected with morphine, with or without the ferroptosis inhibitor liproxstatin-1. We found that chronic morphine exposure led to morphine antinocic...

GluA1 in central amygdala promotes opioid use and reverses inhibitory effect of pain.

Increasing evidence suggests that long-term opioids and pain induce similar adaptive changes in the brain's reward circuits, however, how pain alters the addictive properties of opioids remains poorly understood. In this study using a rat model of morphine self-administration (MSA), we found that short-term pain, induced by an intraplantar injection of complete Freund's adjuvant, acutely decreased voluntary morphine intake, but not food intake, only at a morphine dose that did not affect pain itself. Pre-tr...

Effect of heat shock protein 70 modulators on the development of morphine analgesic tolerance in rats.

The clinical use of opioid analgesics, such as morphine, is limited by analgesic tolerance, molecular mechanism of which is not well understood. Recently, molecular chaperone heat shock protein 70 (Hsp70) has been demonstrated to play important roles in morphine-induced neuroadaptation. Here, we focused on the involvement of Hsp70 in the development of analgesic tolerance to morphine. Rats were treated with morphine (5, 10, 20 mg/kg, subcutaneously) or saline once daily for 10 consecutive days. Hsp70 modula...

The influence of a new derivate of kisspeptin-10 - kissorphin (KSO) on the rewarding effects of morphine in the conditioned place preference (CPP) test in male rats.

Kissorphin (KSO) is a new peptide derived from kisspeptin-10. Previous study has indicated that this peptide displays neuropeptide FF (NPFF)-like anti-opioid activity. Herein, we examined the influence of KSO (1; 3, and 10 nmol, intravenously [i.v.]), on the rewarding action of morphine (5 mg/kg, intraperitoneally [i.p.]), using the unbiased design of the conditioned place preference (CPP) paradigm in rats. To test the effect of KSO on the acquisition of morphine-induced CPP, KSO and morphine were co-in...

A retrospective study of the association between pain intensity and opioid use with length of stay during musculoskeletal inpatient rehabilitation after primary knee and hip arthroplasty.

The relationship between pain intensity, opioid consumption, and length of stay (LOS) has received little attention in primary, lower extremity joint arthroplasty patients admitted to inpatient musculoskeletal (MSK) rehabilitation.

Cross state-dependent memory retrieval between morphine and norharmane in the mouse dorsal hippocampus.

State-dependent memory (SDM) describes a phenomenon that memory is efficiently restored only when the brain state during restoration matches the state during encoding. Some psychoactive drugs such as morphine, ethanol, and cocaine evoke SDM. The scope of this study was to investigate the cross SDM between morphine and norharmane injected into the dorsal hippocampus of male NMRI mice, and the involvement of μ-opioid receptors (MORs) in the SDM of the drugs. Bilateral cannulae were implanted into the CA1 reg...

Effect of morphine exposure on novel object memory of the offspring: The role of histone H3 and ΔFosB.

It has been demonstrated that alteration in histone acetylation in the regions of the brain involved in the reward which may have an important role in morphine addiction. It is well established that epigenetic changes prior to birth influence the function and development of the brain. The current study was designed to evaluate changes in novel object memory, histone acetylation and ΔFosB in the brain of the offspring of morphine-withdrawn parents. Male and female Wistar rats received morphine orally for 21...

Age- and sex-related changes in the severity of physical and psychological dependence in morphine-dependent rats.

Gender- and age-dependent effects on the severity of morphine dependence are still controversial. The aim of this study was to investigate the effects of age and sex on the severity of physical and psychological dependence in morphine-dependent rats. The young/aged male and female Wistar rats were chronically treated with bi-daily doses (10 mg/kg, at 12 h intervals) of morphine for 14 days. Then, rats were tested for the severity of physical dependence on morphine (spontaneous withdrawal signs), anxie...

Cannabinoid receptor modulation changes the accumbal neuronal responses to morphine in the reinstatement of morphine-induced conditioned place preference.

The nucleus accumbens (NAc) is a central component of the brain reward system. It has been known that most of the drugs of abuse such as opioids and cannabinoids affect the NAc. Although cannabinoids can modulate different stages of morphine encounter such as the reinstatement of morphine-induced conditioned place preference (CPP), there is no evidence for the NAc neurons' response to prove it. That is why the present study was designed. The procedure was as follows: The rats were entered to CPP by sc 5 mg/...

Morphine-induced RACK1-dependent autophagy in immortalized neuronal cell lines.

Autophagy is a critical cellular catabolic process in cell homoeostasis and brain function. Recent studies indicate that RACK1 is involved in autophagosome formation in Drosophila and mice and that it plays an essential role in morphine-associated memory. However, the exact mechanism of the role of RACK1 in morphine-induced autophagy is not fully understood.

Long non-coding RNA MEG3 attends to morphine-mediated autophagy of HT22 cells through modulating ERK pathway.

Morphine is an alkaloid isolated from the poppy plants. The addiction of morphine is a very serious social issue. Some long non-coding RNAs (lncRNAs) have been proposed to engage in drug addiction. Whether lncRNA maternally expressed gene 3 (MEG3) attended to morphine-mediated autophagy of mouse hippocampal neuronal HT22 cells was probed. HT22 cells were subjected to 10 µM morphine for 24 h. Cell autophagy was assessed by measuring LC3-II/LC3-I and Beclin-1 expression. qRT-PCR was carried out to meas...

Spinal serum- and glucocorticoid-regulated kinase 1 (SGK1) signaling contributes to morphine-induced analgesic tolerance in rats.

Accumulating evidence indicates that phosphorylated serum- and glucocorticoid-regulated kinase 1 (SGK1) is associated with spinal nociceptive sensitization by modulating glutamatergic N-methyl-D-aspartate receptors (NMDARs). In this study, we determined whether spinal SGK1 signaling contributes to the development of morphine analgesic tolerance. Chronic morphine administration markedly induced phosphorylation of SGK1 in the spinal dorsal horn neurons. Intrathecal injection of SGK1 inhibitor GSK-650394 reduc...
