Department of State and then brought to the US.[63] The report published by the committee noted that while methadone was potentially addictive, it produced less sedation and respiratory depression than morphine and was thus interesting as a commercial drug.[63] In the early 1950s, methadone (most times the racemic HCl salts mixture) was also investigated for use as an antitussive.[66] From this research came a generally non-controlled—or controlled for having the same precursors and effects of strong pure agonist agents of the open chain type, this one a phenaloxam derivative, levopropoxyphene with optical isomerism and one of which appeared to have no narcotic properties but was an antitussive which did have dissociative effects if misused; the isomer form which is removed from the racemic salts to yield dextromethorphan, or remove the other isomer to purify a dextropropoxyphene, or left in to finish with a racemic salts mixture dimethorphan.[67] The open chain opioids tend to have at least one isomer that is at some level a strong pure mu opioid receptor agent.[68] Isomethadone, noracymethadol, LAAM, and normethadone were first developed in Germany, United Kingdom, Belgium, Austria, Canada, and the United States in the thirty or so years after the 1937 discovery of pethidine, the first synthetic opioid used in medicine, prolonging and increasing length and depth of satiating any opiate cravings and generating very strong analgesia (the long metabolic half-life and the strong receptor affinity at the mu opioid receptor sites, therefore imparting much of the satiating and anti-addictive effects of methadone) by means of suppressing drug cravings and the discovery in the early 1950s.[69] of methadone's antitussive properties first tested in dogs in Europe in 1952-1955 with different inert placebos, active placebos like codeine.[70] It was only in 1947 that the drug was given the generic name “methadone” by the Council on Pharmacy and Chemistry of the American Medical Association. As naltrexone has a longer half-life, it is more difficult to titrate. Call your doctor at once if you have any of these serious side effects: shallow breathing; hallucinations or confusion; chest pain, dizziness, fainting, fast or pounding heartbeat; or trouble breathing, feeling light-headed, or fainting. In severe overdosage, particularly by the intravenous route, apnea, circulatory collapse, cardiac arrest, and death may occur.
Other drugs may interact with methadone, including prescription and over-the-counter medicines, vitamins, and herbal products. Its use for the treatment of addiction is usually strictly regulated. According to a report published by the Washington University in St.
The drug is considered a Schedule II narcotic, which means it has accepted medical uses and can legally be prescribed by physicians in the United States; it is prescribed to treat severe, chronic pain, such as that associated with cancer.

IF YOUR GOING TO DO IT WATER IT DOWN A LITTLE BUT I DO NOT RECOMMEND DOING IT AT ALL. The private clinics are more expensive to attend but usually have either a short or no waiting list. Head Injury And Increased Intracranial Pressure The respiratory depressant effects of opioids and their capacity to elevate cerebrospinal-fluid pressure may be markedly exaggerated in the presence of head injury, other intracranial lesions or a pre-existing increase in intracranial pressure. Anxiety Since methadone as used by tolerant patients at a constant maintenance dosage does not act as a tranquilizer, patients will react to life problems and stresses with the same symptoms of anxiety as do other individuals. This should be done in cooperation with a qualified physician if you can find one to trust. It's uncommon for tablets to be crushed and injected, but even the injectable solution can cause problems, especially if the same needle is used with multiple people or for multiple doses.
