A practical approach to determine cutoff concentrations for opiate testing with simultaneous detection of codeine, morphine, and 6-acetylmorphine in urine. (1/272)

BACKGROUND: Both the Department of Defense (DoD) and the Department of Health and Human Services (DHHS) currently require two confirmation tests to verify use of heroin, one test for total morphine and a separate test for 6-acetylmorphine (6-AM). Our aim was to determine appropriate free-codeine, free-morphine, and 6-AM cutoff concentrations that could be substituted for total-morphine, total-codeine, and 6-AM cutoff concentrations and to develop a less labor-intensive method for measuring codeine, morphine, and 6-AM. METHODS: Urine samples containing opiates were extracted, derivatized, and analyzed using gas chromatography-mass spectrometry with selective ion monitoring. RESULTS: The limits of detection for codeine, morphine, and 6-AM were 6, 5, and 0.5 microg/L, respectively. Recoveries were >90%. Quantification was linear over the concentration range of 6-1000 microg/L for codeine, 5-5000 microg/L for morphine, and 0.5-800 microg/L for 6-AM. Cutoff concentrations for confirmation of opiates were 100, 100, and 10 microg/L for free codeine, free morphine, and 6-AM. CONCLUSION: The proposed cutoff concentrations for free morphine and 6-AM provide better detection windows for morphine and heroin use than the cutoff concentrations for total morphine and 6-AM used at present. Detection of free codeine, instead of total codeine, simplifies interpretation of codeine use. The single-extraction method enables simultaneous, less labor-intensive analysis of morphine, codeine, and 6-AM.  (+info)

Pharmacokinetic modeling of M6G formation after oral administration of morphine in healthy volunteers. (2/272)

BACKGROUND: Morphine is metabolized to two major metabolites, morphine-3-glucuronide and morphine-6-glucuronide (M6G). Under the conditions of long-term oral morphine administration, the accumulation of M6G may contribute to the analgesic effects, but it may also cause respiratory depression. METHODS: Five healthy male volunteers (ages 25-34 yr) received 90 mg MST (morphine sulfate 5H2O sustained-released tablet, equivalent to 67.8 mg oral morphine). Multiple plasma and urine samples were taken for as long as 14 and 36 h, respectively. Individual pharmacokinetics after intravenous administration of morphine and M6G were available from a previous investigation. A new model that considers the M6G-plasma profile as a sum of the input from the first-pass metabolism of morphine and the input from systemically available morphine was applied to the plasma concentration versus time curves of M6G. The concentrations of M6G at the effect site after long-term morphine administration were simulated. RESULTS: The fraction of morphine absorbed from the gut was 82+/-14%. Of this, 42+/-8% passed through the liver, resulting in an oral bioavailability of morphine of 34+/-9%. Of the total amount of M6G, 71+/-7% was formed during the first-pass metabolism, and 29+/-7% was formed by metabolism of systemic morphine. After 36 h, the amounts of M6G and morphine excreted in the urine were 92+/-17% and 9+/-3%, respectively. Simulation of effect-site concentrations of M6G indicated that after multiple oral dosing of morphine in patients with normal liver and renal function, M6G might reach concentrations two times greater than that of morphine. CONCLUSIONS: M6G may contribute to the analgesic and side effects seen with long-term morphine treatment. The current model of morphine and M6G pharmacokinetics after oral administration of morphine may serve as a pharmacokinetic basis for experiments evaluating the analgesic contribution of M6G with long-term oral dosing of morphine.  (+info)

Pharmacokinetics of morphine and its glucuronides following intravenous administration of morphine in patients undergoing continuous ambulatory peritoneal dialysis. (3/272)

BACKGROUND: Conjugation with glucuronic acid represents the major route of biotransformation of morphine. The glucuronides morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G) are eliminated via the kidneys. Therefore, chronic renal failure should affect the disposition of M3G and M6G. Numerous patients undergoing long-term continuous ambulatory peritoneal dialysis (CAPD) require pain treatment with morphine. There are only limited data available about the disposition of morphine and its active metabolites M6G and M3G in patients on CAPD. We therefore investigated the pharmacokinetics of morphine and its metabolites in CAPD patients. METHODS: This was a single intravenous dose pharmacokinetic study in 10 CAPD patients (1 female, 9 male, age 31-69 years). Morphine-hydrochloride (Mo) (10 mg) was administered intravenously. Serum, urine, and dialysate samples were collected during 24 h. GC-MS-MS and HPLC-MS methods were used to quantify respectively morphine and morphine glucuronides. RESULTS: While systemic clearance of morphine (1246+/-240 ml/min) was in the range observed in patients with normal kidney function, both M3G and M6G showed substantial accumulation. The area under the concentration-time curve (AUC) ratio of M3G:Mo (33.4+/-7.1) and of M6G:Mo (12.2+/-3.2) was 5.5 and 13.5 times higher than in patients with normal kidney function. Renal clearances of morphine, M3G, and M6G (morphine 3.0+/-2.5 ml/min; M3G 3.9+/-2.2 ml/min; M6G 3.6+/-2.2 ml/min) and dialysate clearances (morphine 4.1+/-1.3 ml/min; M3G 3.2+/-0.7 ml/min; M6G 3.0+/-0.8 ml/min) were extremely low. Therefore the accumulation of M6G and M3G is readily explained by kidney failure which is not compensated by CAPD. CONCLUSION: Accumulation of M3G and M6G is due to the substantially lowered clearance by residual renal function and peritoneal dialysis. In view of the accumulation of potential active metabolites, subsequent investigations have to assess the frequency of side-effects in patients on CAPD.  (+info)

Detection of 6-acetylmorphine in vitreous humor and cerebrospinal fluid--comparison with urinary analysis for proving heroin administration in opiate fatalities. (4/272)

The concentrations of morphine and 6-acetylmorphine (6-AM) in urine, cerebrospinal fluid (CSF), and vitreous humor (VH) and the morphine concentrations in blood were determined by gas chromatography-mass spectrometry for 29 fatalities after abuse of heroin either alone or in combination with alcohol and other drugs. 6-AM was found above a quantitation limit of 1 ng/mL in urine in 89% of the cases, in CSF in 68% of the cases, and in VH in 75% of the cases. The 6-AM concentrations in CSF (mean, 10 ng/mL) and VH (mean, 17 ng/mL) were in general much smaller than in urine (mean, 170 ng/mL); therefore, the different pharmacokinetic behavior of the fluids is discussed. There is no uniformity between the three fluids with respect to the presence or absence of 6-AM. Therefore, CSF or VH may be used as complementary or alternative materials to urine in order to prove heroin uptake in opiate fatalities.  (+info)

GC-MS confirmation of codeine, morphine, 6-acetylmorphine, hydrocodone, hydromorphone, oxycodone, and oxymorphone in urine. (5/272)

A procedure for the simultaneous confirmation of codeine, morphine, 6-acetylmorphine, hydrocodone, hydromorphone, oxycodone, and oxymorphone in urine specimens by gas chromatography-mass spectrometry (GC-MS) is described. After the addition of nalorphine and naltrexone as the two internal standards, the urine is hydrolyzed overnight with beta-glucuronidase from E. coli. The urine is adjusted to pH 9 and extracted with 8% trifluoroethanol in methylene dichloride. After evaporating the organic, the residue is sequentially derivatized with 2% methoxyamine in pyridine, then with propionic anhydride. The ketone groups on hydrocodone, hydromorphone, oxycodone, oxymorphone, and naltrexone are converted to their respective methoximes. Available hydroxyl groups on the O3 and O6 positions are converted to propionic esters. After a brief purification step, the extracts are analyzed by GC-MS using full scan electron impact ionization. Nalorphine is used as the internal standard for codeine, morphine, and 6-acetylmorphine; naltrexone is used as the internal standard for the 6-keto-opioids. The method is linear to 2000 ng/mL for the 6-keto-opioids and to 5000 ng/mL for the others. The limit of quantitation is 25 ng/mL in hydrolyzed urine. Day-to-day precision at 300 and 1500 ng/mL ranged between 6 and 10.9%. The coefficients of variation for 6-acetylmorphine were 12% at both 30 and 150 ng/mL. A list of 38 other basic drugs or metabolites detected by this method is tabulated.  (+info)

Topical opioids in mice: analgesia and reversal of tolerance by a topical N-methyl-D-aspartate antagonist. (6/272)

In addition to its central actions, morphine has important peripheral effects. To examine peripheral analgesic mechanisms, we developed a topical opioid paradigm in which the tail was immersed in a dimethyl sulfoxide (DMSO) solution containing various drugs. Alone, DMSO was inactive in the tail-flick assay in mice. DMSO solutions containing morphine and peptides such as [D-Ala2,MePhe4, Gly(ol)5]enkephalin (DAMGO) produced a potent, dose-dependent analgesia with the radiant heat tail-flick assay. The actions of the drugs were local. Analgesia was observed only in regions of the tail exposed to the solution and not in more proximal unexposed portions of the tail. Immersion of the tail in a solution containing either 125I-labeled morphine or 125I-labeled DAMGO revealed no detectable uptake of radioactivity into the brain, spinal cord, or blood. In the tail, radioactivity was limited only to the regions actually immersed in the solutions. The topical drugs potentiated systemic agents, similar to the previously established synergy between peripheral and central sites of action. Local tolerance was rapidly produced by repeated daily exposure of the tail to morphine. Topical morphine tolerance was effectively blocked by the N-methyl-D-aspartate (NMDA) antagonist MK801 given either systemically or topically but not intrathecally. The ability of a topical NMDA antagonist to block local morphine tolerance suggests that peripheral NMDA receptors mediate topical morphine tolerance. Morphine was cross-tolerant to DAMGO, but not to morphine-6beta-glucuronide, implying different mechanisms of action. These observations are significant in the design and use of opioids clinically.  (+info)

kappa-Opioid receptor effects of butorphanol in rhesus monkeys. (7/272)

Butorphanol and nalbuphine have substantial affinity for mu and kappa-opioid receptor sites, yet their behavioral effects in monkeys are largely consistent with a mu receptor mechanism of action. Using ethylketocyclazocine (EKC) discrimination and diuresis assays in rhesus monkeys (Macaca mulatta), the purpose of the current investigation was to characterize the in vivo kappa-opioid activity of these compounds through the use of an insurmountable mu-opioid receptor antagonist, clocinnamox. Alone, butorphanol (0.001-0.032 mg/kg i.m.) failed to generalize to EKC, and pretreatment with the competitive opioid receptor antagonist quadazocine (0.1 or 0.32 mg/kg i.m.) did not alter this generalization. At 24 h after clocinnamox (0.1 mg/kg i.m.) administration, butorphanol fully generalized to EKC, and this generalization was maintained in two of three monkeys at 72 h. Parallel results were observed in diuresis: butorphanol alone and in the presence of quadazocine (1 mg/kg i.m.) did not alter urine output, and a marked diuretic effect was demonstrated 24 h to 2 weeks after clocinnamox administration. Clocinnamox did not alter the discriminative stimulus or diuretic effects of nalbuphine or of the kappa-opioid receptor agonists EKC or U69593. These results are consistent with an in vivo agonist activity of butorphanol at kappa-opioid receptors that can only be demonstrated when an insurmountable antagonist has substantially eliminated the dominant receptor population through which it exerts its action.  (+info)

Morphine and morphine-6-glucuronide in the plasma and cerebrospinal fluid of children. (8/272)

AIMS: To measure morphine and morphine-6-glucuronide in the plasma and cerebrospinal fluid of children following a single intravenous dose of morphine. METHODS: Twenty-nine paired samples of cerebrospinal fluid and plasma were collected from children with leukaemia undergoing therapeutic lumbar puncture. An intravenous dose of morphine was administered at selected intervals before the procedure. Concentrations of morphine and morphine-6-glucuronide (M6G) were measured in each sample. Morphine was measured using a specific radioimmunoassay (r.i.a.) and M6G was measured using a novel enzyme-linked immunosorbent assay (ELISA). RESULTS: The ELISA for measuring M6G was highly sensitive. The intra-and interassay variations were less than 15%. Using a two-compartment model for plasma morphine, the area under the curve to infinity (AUC, 7143 ng ml-1 min), volume of distribution (3.6 l kg-1 ) and elimination half-life (88 min) were comparable with those reported in adults. Clearance (35 ml min-1 ) was higher than that in adults. Morphine-6-glucuronide was readily synthesized by the children in this study. The elimination half-life (321 min) and AUC (35507 ng ml-1 min) of plasma M6G were much greater than those of morphine. CONCLUSIONS: Extensive metabolism of morphine to M6G in children with cancer has been demonstrated. These data provide further evidence to support the importance of M6G accumulation after multiple doses. There was no evidence that morphine passed more easily into the CSF of children than adults.  (+info)

Following its intake, heroin is rapidly hydrolyzed into 6-monoacetylmorphine, and at some point right into morphine. Glucuronides are after that conjugated into the 3- as well as 6- positions of morphine to create the metabolites: morphine-3-glucuronide as well as morphine-6-glucuronide. Upon formation of these glucuronides, they are excreted largely by means of the pee- and also to a minimal level via bile.. Assuming an individual injected heroin intravenously, virtually 70% of the medications metabolites would show up in urine, mostly through conjugated morphine (over 50%). Various various other metabolites that show up in pee post-heroin consumption consist of: normorphine, codeine, morphine-3-6-diglucuronide, and morphine-3-ethersulphate. The majority of morphine undertakes glucuronidation in the liver, yet various other organs such as the kidney, intestines, and also mind have a bit part in the process.. Generally, the fifty percent life of heroin ranges in between 1.3 minutes and also 7.8 ...

The aim of the present study was to investigate the reinforcing effects of 6-AM and its role in mediating those of heroin. We used an intravenous self-administration procedure in male Sprague-Dawley rats including four phases: acquisition, extinction, reinstatement of drug-seeking, and re-acquisition. Independent groups of rats readily learned to self-administer equimolar doses (0.135 μmol/kg) of either 6-AM (44.3 μg/kg) or heroin (50 μg/kg). Under ...
Heterocodeine (6-methoxymorphine) is an opiate derivative, the 6-methyl ether of morphine, and a structural isomer of codeine; it is called hetero- because it is the reverse isomer of codeine. Heterocodeine was first synthesised in 1932 and first patented in 1935. It can be made from morphine by selective methylation. Codeine is the natural mono-methyl ether, but must be metabolized for activity (that is, it is a prodrug). In contrast the semi-synthetic mono-methyl ether, heterocodeine is a direct agonist. The 3,6 methyl di-ether of morphine is thebaine. Heterocodeine is 6 times more potent than morphine due to having a substitution at the 6-hydroxy position, in a similar manner to 6-acetylmorphine. The drug methyldihydromorphine (dihydroheterocodeine) is a derivative of heterocodeine. Like the morphine metabolite morphine-6-glucuronide, 6-position branches (esters or ethers) of morphine bind to the otherwise unagonized human mu receptor subtype mu-3 (or μ3); as well as the 6-acetylmorphine ...
To evaluate the analgesic effect of spinal block and systemic morphine, we conducted a preliminary experiment. Analgesia was evaluated by the tail-flick (TF) test. The light beam from a projector bulb was focused on the middle portion of the tail to produce a spot of intense heat, and the TF latency was measured. The intensity of the thermal stimulus was adjusted so that the baseline TF latency was 1.0-2.5 s. A 10-s cutoff time was imposed to minimize tissue damage. In all experiments, the TF latency was determined three times for each mouse. Measurements were obtained before intervention and at 10, 30, 60, 120, 180, 240, 300, and 360 min after awaking from anesthesia. We tested five regimens of spinal block (25 μg bupivacaine alone, 25 μg bupivacaine plus 0.5 μg morphine, 25 μg bupivacaine plus 1.25 μg morphine, 25 μg bupivacaine plus 2.5 μg morphine, and 25 μg bupivacaine plus 5 μg morphine) and systemic injection of morphine (5 mg/kg intraperitoneally23). We also tested two control ...

An original, sensitive, and specific high-performance liquid chromatographic (HPLC) assay was developed for the quantitation of morphine and its two major metabolites, morphine-3-glucuronide (M3G) and morphine-6-glucuronide (M6G), in human plasma and cerebrospinal fluid (CSF) and in rat plasma, using hydromorphone as the internal standard. Solid-phase extraction was used to separate morphine and its glucuronide metabolites from plasma constituents. Extraction efficiencies of morphine, M3G, and M6G from human plasma samples (0.5 ml) were 84, 87, and 88%, respectively. Extraction efficiencies of morphine, M3G, and M6G did not differ significantly (p > 0.05) between human plasma and CSF or rat plasma. Morphine, M3G, M6G, and hydromorphone were separated on a 10 mu C-8 Resolve radially compressed cartridge using a mobile phase comprising methanol:acetonitrile:phosphate buffer, (0.0125M pH 7.5; 10: 10:80), in which 11 mg/L of cetyltrimethylammonium bromide (cetrimide) was dissolved.

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 ...
TY - JOUR. T1 - A cohort study of the association between serum immunoglobulin G concentration and preweaning health, growth, and survival in Holstein calves. AU - Pithua, P.. AU - Aly, Sharif S. PY - 2013. Y1 - 2013. N2 - The association between serum IgG concentration and preweaning health performance in Holstein calves were evaluated in a prospective cohort study design framework. Post colostral blood samples were collected from 561 calves and serum IgG concentrations were quantitated using a single radial immunodiffusion assay. Preweaning treatments for diarrhea, pneumonia, omphalitis and frequency of antibiotic therapy plus calf death events were recorded until calves were weaned at approximately 60 d of age. Logistic regression modeling was used to evaluate the association between failure of passive transfer of immunity (FPT, serum IgG , 10g/L) and risk of diarrhea, pneumonia, omphalitis, frequency of antibiotic therapy and death. Calves with FPT were twice as likely to suffer from scours ...
Morphine- and buprenorphine-induced analgesia and antihyperalgesia in a human inflammatory pain model: a double-blind, randomized, placebo-controlled, five-arm crossover study Pernille Ravn,1 Erik L Secher,2 Ulrik Skram,3 Trine Therkildsen,1 Lona L Christrup,1 Mads U Werner41Department of Drug Design and Pharmacology, University of Copenhagen, 2Department of Anesthesiology, Juliane Marie Center, Rigshospitalet, Copenhagen University Hospitals, 3Department of Intensive Care, Gentofte Hospital, Copenhagen University Hospitals, 4Multidisciplinary Pain Center, Neuroscience Center, Rigshospitalet, Copenhagen University Hospitals, Copenhagen, DenmarkPurpose: Opioid therapy is associated with the development of tolerance and paradoxically increased sensitivity to pain. It has been suggested that buprenorphine is associated with a higher antihyperalgesia/analgesia ratio than µ-opioid receptor agonists. The primary outcome of this study was therefore to investigate relative differences in antihyperalgesia and
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
If turns out that newborns have trouble metabolizing morphine, but in general the amount of morphine in breast milk is low enough to avoid problems. In this case, however, the mother was heterozygous for a variant in the gene CYP2D6, which encodes the enzyme that converts codeine to morphine. As a heterozygote, she was an ultra-rapid metaboliser, meaning the codeine she took was converted quickly to morphine. Confirming this, the concentration of morphine in here milk was higher than normal: A morphine concentration of 87 ng/mL was found-the typical range of milk concentrations after repeated maternal codeine is 1·9-20·5 ng/mL at doses of 60 mg every 6 h ...

Dr. Ness has been taking good care of me since 1988. Last year I needed major shoulder surgery and he referred me to an orthopedic surgeon who had the same compassion and medical values as Dr. Ness. Major surgery is no picnic, but with the kind and caring support of Dr. Ness, my surgeon and the team at Woodwinds Health Campus, my recovery was faster than expected, I was able to start physical therapy sooner and get my life back to normal. I credit the success of my surgery and recovery to the relationship between Dr. Ness and I, and in him knowing not only my medical history, but knowing me as a person and providing the level of care based on that knowledge. By the way, the day after I returned home from the hospital, Dr. Ness called to see how things went and more importantly how I was doing. ...

Opioids are considered the golden standard in pain management for both humans and small animals, but is used less often in equine medicine - probably for fear of side effects. Are there any studies that suggest that side effects are a major problem, or is it lack of experience which is the greatest obstacle to use? As early as 1937 it was shown that morphine and morphine derivatives provide analgesia in horses. For species other than horses used opioids often both pre-, intra-and postoperatively. They relieve pain effectively and are often included in the anesthesia protocol. That way you can reduce the need for anesthetic gases and thus the risk of cardiovascular depression. In horses, it seems that there is a fine line between analgesia and excitation, which must be taken into account when used. There are also a number of side effects, mainly gastrointestinal, that makes people reluctant to use opioids. There is also a concern that the pain relief will mask a progressive disease state. This ...

Morphine has low bioavaliability when taken orally, that means if you eat the thing less than 30% will actually hit your head, given the fact that you took a low dose and other factors is the reason why you didnt feel much if anything. Unless your using needles, morphine (like most opiates) is best either snorted or plugged. Snorted is my choice (because I dont like sticking pointed objects a bit far into my ass), just make sure you lick and wipe off the time release coating. Even then the impacted time release clusters of uncrushable small powders can make for a weird way of coming up. One time I sniffed a whole 100mg pill, didnt feel anything that day, and then woke up the next day nodding out for hours ...
