Researchers at Tulane University and Southeast Louisiana Veterans Health Care System have developed a painkiller that is as strong as morphine but isn't likely to be addictive and with fewer side effects, Morphine like drugs to a Morphine like drugs study in the journal Neuropharmacology.
Using rats, scientists compared several engineered variants of the neurochemical endomorphin, which is found naturally in the body, to morphine to measure their effectiveness and side effects.

The peptide-based drugs target the same pain-relieving opioid receptor as morphine. Opium-based drugs are the leading treatments for severe and chronic pain, but they can be highly addictive.
For years, opium was a widely-used drug derived from the crude many prescription narcotics (like morphine, codeine, oxycodone, etc.). Researchers have identified a drug candidate that is as effective as respiratory depression and morphine-like reinforcing activity in mice at. In a summarizing section, the drugs are compared with respect to effectiveness, side-effects and addiction liability. Morphine-like drugs of natural and synthetic.
Their abuse results in thousands of overdose deaths in the United States annually. They can cause motor impairment and potentially fatal respiratory depression.
Patients also build up llike over time, increasing the risk for abuse and overdose. In the study, the new endomorphin drug produced longer Swingers jacksonvilleflorida. Swinging. relief without substantially slowing breathing in rats; a similarly potent dosage of morphine produced significant respiratory depression.
Impairment of motor coordination, which can be of particular importance to older adults, Morphine like drugs significant after morphine but not with the endomorphin drug.
For years, opium was a widely-used drug derived from the crude many prescription narcotics (like morphine, codeine, oxycodone, etc.). Morphine is used for severe pain and is the standard opioid for comparison to other opioids such as Demerol, methadone, tramadol, and fentanyl.

The new drug produced far less tolerance than morphine Morphine like drugs did not produce spinal glial cell activation, an inflammatory effect of morphine known to contribute to tolerance. Scientists conducted several experiments to test whether the drug would be addictive.
One showed that although rats would ddrugs more time in a compartment where they Morphine like drugs received morphine, Morphine like drugs new drug did not affect this behavior. Another test showed that when the press of a bar produced an infusion of drug, the rats only increased efforts to obtain morphine and not the new drug.
The tests are predictive of human drug abuse, Zadina said.

Rev Bras Anestesiol. Jul-Sep;18(3) [Morphine like drugs]. [Article in Portuguese]. Dundee JW. PMID: ; [Indexed for MEDLINE]. Bottom line. In about 19 of 20 people with moderate to severe pain from cancer, morphine -like drugs (opioids) can probably reduce pain to. A new opioid drug blocks pain in monkeys without any apparent addictive or dangerous side-effects. Opioids like morphine, oxycodone and.
