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 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 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 They said I had 136 nanograms of Morphine in my system and honestly I have never taken anything not prescribed to me. If I indeed did take the Morphine I would’ve owned up to it. I rely on these prescriptions to keep me functioning and employed.
Avatar n tn Short Answer: This depends on your metabolism, but in general it will stay in your system for 24-36 hours with a *low dose* (ie. no more than 30mg of codein). However with larger doses, it will be in your system for 48-72 hours depending on how high your dosage was. Long Answer: The half-life of codeine is 2.9 hours. This means that in 2.9 hours, only half the amount of codeine is remaining. In another 2.9 hours another half of that, and so on.
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 f tn That is what happened. How could I not have any metabolites if I take my meds everyday and have been for months on this med when they took opana off the market. Either the lab made mistakes or there is a physical problem in my body. I took my meds.
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 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 n tn Heroin breaks down into codeine and morphine. 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.
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 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 , 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 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 m tn Can cocaine metabolites bind to sperm and be carried to the female egg causing damage? Are cocaine metabolites toxic? Does the female body reject sperm with foreign matter on them during sperm capacitation or other stages? Any help would be greatly appreciated!
Avatar f tn I have severe chronic back pain. I've had chronic back pain from an abusive relationship 13 years ago and two car accidents. I'm on Long Term Disability from work. I've had a total of 13 different injection procedures that last maybe for 3 months along with back pills. 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.
Avatar n tn i was urine tested several weeks ago and passed then they came back and said i had eddp-ms in my urine which is methadone metabolites but i havent taken metadone i am however on several medications for bi-polar dissorder and was wondering what if anything would cause me to test positive for the metabolites but not the methadone
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 n tn 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 f tn Today, my doctor just informed me he can no longer be my doctor. Until today, my worst battle has always been with Berkshire Hathaway, the workers comp insurance company. Today, my urine test from the same hospital lab apparently came in negative twice for Hydrocodone and alprazolam but positive for Morphine Sulfate.
Avatar m tn Using a targeted cholesterol metabolomic platform we evaluated paired HCV G2 and G3 patient sera for changes in in vivo HCV sterol pathway metabolites. We compared HCV genotypic differences in baseline metabolites and following antiviral treatment to assess whether sterol perturbation resolved after HCV eradication. We linked these metabolites to IR and urine oxidative stress markers.

Avatar f tn ) or elimination may be expected to influence the degree and extent of accumulation of the active metabolites of bupropion. The elimination of the major metabolites of bupropion may be affected by reduced renal or hepatic function because they are moderately polar compounds and are likely to undergo further metabolism or conjugation in the liver prior to urinary excretion.
