Morphine metabolites

Common Questions and Answers about Morphine metabolites


Avatar f tn I am on methadone for narcotic addiction. My metabolites have came back very high in my urine analysis for the last couple months. I am not taking any extra from what i am prescribed. What could be causing this?
Avatar n tn Do norco fentanyl and morphine create the same metabolite in urine tests?
Avatar n tn If you have gastro paresis can it make your drug test negative for morphine but your actually taking morphine?
Avatar f tn On a UDS using the GC/MS or LC/MS Opiates UDS the metabolites of Morphine, may show Hydromorphone if on high dose or chronic Morphine . I found another site that stated, "A new study confirm that hydromorphone is a minor metabolite of morphine and appears on urine drug testing (UDT)." This was an older article but still was discussing the results of a Gas chromatography-mass spectroscopy GCMS, UDS.
Avatar n tn When I moved to Mexico three years ago methadone was available, but it has recently (six months ago) been replaced by morphine, so I have been taking morphine since then. While morphine does seem to reduce my pain, it is not effective in affordable quantities. I go through about 400 30mg tabs a month. Curiously, methadone, one of the worlds least expensively manufactured drugs is twice the price of morphine here in Mexico.
Avatar f tn While buprenorphine metabolites do not include these opioids, false positives can include morphine, codeine, heroin, and opium. The instant UDT test is simply not accurate. Incidentally, the naloxone in your Suboxone film will nulify any effects of opiates like morphine. A specific quantitative testing for buprenorphine should be made to monitor compliance with Suboxone therapy.
Avatar f tn It is transformed into active metabolites (which provide analgesia) and passive metabolites (which to not help pain. Some of these metabolites are toxic in large amounts. These metabolites are excreted by the kidneys. Thus, opioids can build up, including their toxic metabolites, with liver and kidney disease. This can cause problems. I've been using opioid analgesics for a long time, also, although not at this level.
Avatar f tn I had my first pain management appointment the second week of December. I do not take drugs illegally and certainly do not take medication that is not prescribed to me. I was given my first drug test which came back negative for everything. 2 weeks later, I got a call from their office saying I had "unprescribed morphine" come back on my lab results. I was told that I have to attend addiction counseling in order to continue with their treatment.
Avatar n tn Codeine breaks down into morphine. The opiate drug tests look for codeine, morphine, and 6-acetyl-morphine. The presence of 6-acetyl-morphine is relatively conclusive of recent heroin use, but is only detectable for a few hours after use. The presence of codeine can be the result of either heroin or codeine use. The presence of morphine can be the result of the use of heroin, codeine, or morphine. Relative levels of codeine and morphine can help determine their origin.
Avatar n tn However you must keep in mind that codeine is a prodrug. It's main metabolite is Morphine. Some of these metabolites can remain in your system in low traces, for upto 72 hours. It all depends on your dosage.
Avatar n tn Yes, it is quite common to get false positive oxycodone test when you are being tested for hydrocodone. This is because there are some morphine like metabolites which may be common to both. You need to talk to your doctor regarding this. Take care! The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you.
Avatar n tn Normetabolites on drug testing such as norcodeine are unique metabolites. This means you cannot get them until you consume a drug that has norcodeine. MS-contin contains morphine sulfate. So, its metabolite can be normorphine but not nor codeine. Hence your doctor may be suspecting that you are taking norcodeine or a similar drug. Take care! The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you.
Avatar n tn Can Vicoden show up as traces of Morphine in a UA? Son had a UA that came back dirty with traces of morphine showing up. He was on Vicoden for a broken bone a while before and swears upside down and sideways he had not taken anything other than the Vicoden. What else would show up as Morphine? Where can we find info on this? Am I being strung alone or does this have any merit?
Avatar n tn Heroin is a semisynthetic opiate that by virtue of its metabolism to morphine produces a positive result on standard EIA tests. Morphine is then further metabolized to morphine-3-glucuronide and morphine-6-glucuronide before excretion (primarily via the kidneys). However, prior to its metabolism to morphine and subsequent glucuronidation, heroin is rapidly metabolized to 6-MAM.
Avatar n tn For ease of use, the detection times of metabolites have been incorporated into each parent drug. For example, heroin and cocaine can only be detected for a few hours after use, but their metabolites can be detected for several days in urine. In this type of situation, we will report the (longer) detection times of the metabolites. NOTE 1: Oral fluid or saliva testing results for the most part mimic that of blood. The only exceptions are THC and benzodiazepines.
Avatar f tn The metabolism of codeine results in other opioid metabolites, including morphine, and a minor amount of hydrocodone. In fact, this is how codeine works -- by itself, codeine is ineffective. But because it is metabolized into a small amount of morphine, it is effective against pain. Depending on the laboratory method used by your doctor's testing service, false positives can be reported if their "cut-off level" is set too low.
Avatar f tn Even at that I would suspect that the metabolites are still present even after a couple of days. I really am just posting here as I did not realize that false negatives were such a problem until I came to this and a couple of other sites to investigate. I wish I knew how we, as patients, could be more proactive in this situation and get the government off our backs. We are NOT criminals. Does anyone have any ideas?
Avatar n tn The average plasma half life ( half the time a chemical takes to be metabolized and leave the body) is 3.8 hours. Most opiates like morphine, codeine, and heroin are detected up to 2 days after taking the drug in urine, up to 90 days on hair, and 6 hours in blood except for codeine which can be detected up to 12 hours after. NIDA, however, legally prohibits the reporting of the 3 metabolites of hydrocodone.
Avatar f tn , codeine, hydrocodone, meperidine, methadone, morphine, propoxyphene) have active metabolites that are further converted to inactive substances....." Opiates can cause liver damage, some more than others. I wish I had better information for you. I encourage you to discuss this with your physician. .... and Please let us know how you are doing and what you discover. Feel free to post again and ask additional questions. We are Chronic Pain Patients... and get it!
Avatar f tn The metabolism of each opioid leaves traces of metabolites and other chemical byproducts. By assaying the levels of these substances in the blood or urine, the lab can determine, with some degree of certainty, which particular medication you're using -- codeine, oxycodone, morphine, hydromorphone, etc. However, these tests can be wrong because of differences in our individual ability to make specific enzymes for the metabolism of these medications.
Avatar f tn Although methadone and fentanyl are also heavily protein bound and as such require reduced dosing in patients with cirrhosis, the metabolism of these agents does not yield toxic metabolites, and hence they, along with hydromorphone, may be better tolerated37,38 (Table 2)." ".....Hydromorphone and fentanyl appear to be the least affected by renal dysfunction, and fentanyl has less hemodynamic disturbance (due to lack of histamine release associated with other opioids).
Avatar m tn I did that to see how bad my pain really was and to see if the insurance company was right and because my wife said the morphine had changed my personality. The pain is bad and the morphine does change who you are. been off morphine and Valium for 1 year My question is after stopping the morphine and Valium my pain is pretty bad some days I can't get out of bed or function,but the morphine is something I don't wont to ever take again if I can keep from it.
Avatar m tn Trazodone. Trazodone will inhibit opioid metabolites from showing in your urine. I can't believe it. I take 100mg of trazodone every night for sleep, so when my doctor took my urine, tah-dah, no opiates. Upon further research it would seem that it does not affect the analgesia of morphine or oxycodone. Therefore the fact that ms contin doesn't help me with my pain is all me and my silly body. So, for all of my friends out there, we have all learned an interesting lesson.
Avatar f tn My Pain Management center changed my medication about 3 months ago at my request because my body became immune to the meds. and needed something else. They removed my morphine but increased the Oxycodone. I've been seeing this Pain Management since 1999. I checked my lab results on line, when I read them from the urine test it showed cocaine on my lab results.
Avatar f tn Opioids like morphine, codeine, oxycodone, oxymorphone, and a few others, are known as "classic opioids." These medications belong to a chemical class called Phenanthrenes. Fentanyl is an opioid of a different class, called Phenylpiperidines.
Avatar m tn for example a 10 Panel looks for marijuana, cocaine, phencyclidine, opiates, methamphetamine, methadone, amphetamines, barbituates, benzodiazepines and trycyclic antidepressants. The opiates is a panel that detects opiates such as heroin, morphine, codeine and synthetic pain relievers like oxycodone and hydrocodone can be detected for 1 to 4 days, depending upon the form, its metabolites and amount and duration of use. So, I believe it will show up the same...
Avatar m tn Fentanyl is in the same class as Morphine, however, it is synthetic and does not metabolize like other opiates, ie Vicodin, Morphine, Codeine. The urine test is testing for metabolites, ie norhydrocodone, hydromorphone. It depends on the test that is being used and that the assay cutoff is for that particular test. The test for Fentanyl is specific to look for that drug and a normalized value can be detected usually 3-4 days after.
Avatar n tn You seem very smart, that is why I'm asking you this question, I have a prescription for oxycodone, I ran out and have been taking morphine from a old prescription I had. I have to go in for a UA. 3 people told me morphine will test the same as oxycodone because it has the same metabolites is that true?
Avatar m tn I explained to my doc that #1 Whenever I have been in the hospital or in any traumatic incident that required the administration of morphine, the morphine never worked. It really felt like nothing was administered, and I'm talking about multiple injections. I would always end up getting administered fentanyl or dilaudid or both to dull my pain. I also cited the fact that 3 out of 10 caucasions have an inability to absorb and metabolize morphine. It is a well studied genetic mutation.
Avatar n tn The primary metabolites of codeine are morphine, and codeine-6-glucuronide. Not only is codeine converted into morphine in the body, but also several other active compounds. The approximate distribution is as follows: codeine-6-glucuronide (~70%), norcodeine (~10%), and hydromorphone (~1%). Conversion of codeine to morphine occurs in the liver via cytochrome P450 enzyme CYP2D6.
