Answer by the_only_solorose
withdrawing from heroine can be fatal, while withdrawal from methadone is not. So the heroine addict is gradually changed over to methadone, and then safely weaned off of it.

Answer by surfjax32
Because it helps reduce the effects from withdraw from the heroin. Heroin withdraw can be fatal and very dangerous for a person to go through by supplmenting the addiction to that with methadone they can safely help the person withdraw from the herion. Here is some more info on why it was made and the make up of it also what is is used for I hope this helps you. Just as a side note most insurance companies will not cover this type of treatment.
Methadone/dolophine, was first synthesized in 1937 by German scientists Max Bockmühl and Gustav Ehrhart at IG Farben (Hoechst-Am-Main, now part of Frankfurt, Germany) during their search for an analgesic that would be easier to use during surgery (and less potentially addictive, post-op) than morphine. Methadone is a Schedule II drug under the Single Convention on Narcotic Drugs.[1]

On September 11, 1941 Bockmühl and Ehrhart filed an application for a patent for a synthetic substance they called Hoechst 10820 or polamidon and whose structure had no relation to morphine or the opioid alkaloids (Bockmühl and Ehrhart, 1949). Although chemically unlike morphine or heroin, methadone also acts on the opioid receptors and thus produces many of the same effects. Chemically, methadone is the simplest of the opioids.

Methadone was introduced into the United States in 1947 by Eli Lilly and Company as an analgesic (They gave it the trade name Dolophine®, which is now registered to Roxane Laboratories). Since then, it has been best known for its use in treating narcotic addiction, although such a use never became widespread and common until the early 1990’s when Public Policy sought to find ways to reduce the spread of HIV and AIDS. Methadone has since been demonstrated not to reduce disease transmission in non urban users(Hartgers, S.I. Methadone Program Report 2001). It is also used in managing chronic pain due to its long duration of action and very low cost. In late 2004, the cost of a one-month supply of methadone was $ 20, as compared to an equivalent analgesic amount of Demerol at $ 120. Australians have recently utilised methadone to treat amphetamine addictions in the hope of reducing foetal harm among aboriginals.

Methadone (as Dolophine) was first manufactured in the USA by Mallinckrodt pharmaceuticals, a St. Louis-based subsidiary of the Tyco International corporation. Mallinckrodt held the patent up until the early 1990s. Today a number of pharmaceutical companies produce and distribute methadone. However, the major producer remains Mallinckrodt. Mallinckrodt sells bulk methadone to most of the producers of generic preparations and also distributes its own brand name product in the form of tablets, dispersible tablets and oral concentrate under the name Methadose in the United States.

Generally, one will only hear “dolophine” used by older addicts who used the product in the 1960s and 1970s. Medical professionals who believe that dolophine is the generic name for methadone, when actually it is the reverse, may also use the old brand name. A persistent but untrue urban legend claims that the trade name “Dolophine” was coined in tribute to Adolf Hitler by its German creators, and it is sometimes even claimed that the drug was originally named “adolphine” or “adolophine”. The claim is still presented as fact by Church of Scientology literature[2] and was repeated by actor and vocal Scientologist Tom Cruise in a 2005 Entertainment Weekly interview. However, as the magazine pointed out, this isn’t true: the name “Dolophine” was in fact created after the war by the American branch of Eli Lilly,[3] and the name “Adolphine” (never an actual name of the drug) was created in the United States in the early 1970s.[4] Dolophine actually comes from the German Dolphium. The name derives from the Latin dolor which means “pain” and phine which means “end”.

[edit] Pharmacology
Methadone has a slow metabolism and very high lipid solubility, making it longer lasting than morphine-based drugs. Methadone has a typical half-life of 15 to 60 hours, in rare cases up to 190 hours.[5] permitting the administration only once a day in heroin detoxification and maintenance programs. The analgesic activity is shorter than the pharmacological half-life; dosing for pain control usually requires multiple doses per day. The most common mode of delivery at a methadone clinic is in an oral solution, usually Methadose is used. Methadone is almost as effective when administered orally as by injection. As with heroin, tolerance and dependence usually develop with repeated doses. Tolerance to the different physiological effects of methadone varies. Tolerance to analgesia usually occurs during the first few weeks of use; whereas with respiratory depression, sedation, and nausea it is seen within approximately 5-7 days. There is no tolerance formed to constipation produced by methadone or other opioids; however, effects may be less severe after time.

On November 29, 2006, the U.S. Food and Drug Administration issued a Public Health Advisory about methadone titled “Methadone Use for Pain Control May Result in Death and Life-Threatening Changes in Breathing and Heart Beat.” The advisory went on to say that “the FDA has received reports of death and life-threatening side effects in patients taking methadone. These deaths and life-threatening side effects have occurred in patients newly starting methadone for pain control and in patients who have switched to methadone after being treated for pain with other strong narcotic pain relievers. Methadone can cause slow or shallow breathing and dangerous changes in heart beat that may not be felt by the patient.” The advisory urged that physicians use caution when prescribing methadone to patients who are not used to the drug, and that patients take the drug exactly as directed. [1]

Current research shows methadone has a unique affinity for the NMDA (N-methyl-D-aspartic acid) brain receptor. Some researchers propose that NMDA may regulate psychic dependence and tolerance by exhibiting opioid antagonist like activity. Withdrawal symptoms are generally less acutely severe than those of morphine or heroin at equivalent doses, but are significantly more prolonged; methadone withdrawal symptoms can last for several weeks or more, and so individuals maintained on methadone for long periods of time may in fact find it more difficult to give up methadone than people who go directly from heroin use to abstinence.

[edit] Clinical use

[edit] Opioid addiction
Methadone has traditionally been provided to the addiction population in a highly regulated methadone clinic, generally associated with an outpatient department of a hospital. Numerous clinics start addicts at 30mg and raise the dosage 10mg a day until the addict feels they are at a comfortable level of dosage. Clinics such as these stem from programs set up during the Nixon administration to combat heroin use, first in Washington, D.C., then nationwide. In addition to obtaining a daily methadone dose, some who go to this type of clinic for addiction treatment may attend some type of psychological counseling for their addiction. Some are required to attend drug addiction programs but many are not.

Methadone is considered to be generally effective in management of heroin addiction but reduction of HIV rates from needle sharing is questionable due to higher than average propensity for unsafe sex (Hartgers et al). At proper dosing, methadone usually reduces the appetite for and need to take heroin. However, most heroin addicts report more difficulty in quitting methadone than heroin. While there is much debate over the treatment schedule and duration required, treatment at a methadone maintenance clinic is intended to be for an indefinite duration. Many factors determine the treatment dose schedule, and some follow the philosophy that methadone maintenance treatment is not curative for heroin addiction.

[edit] Chronic pain
In recent years, methadone has gained popularity among physicians for the treatment of other medical problems, such as chronic pain. The increased usage comes as doctors search for an opioid drug that can be dosed less frequently than short-acting drugs like morphine or hydrocodone. Another factor in the increased usage is the low cost of methadone. A month’s supply will typically have a retail cost of $ 30-50 in the United States, compared to hundreds of dollars for alternative opioids. Methadone, with its long half-life (and thus long duration of effect) and good oral bioavailability, is a common second-choice drug for pain that doesn’t respond to weaker agonists. Some physicians also choose methadone for treating chronic pain in patients who are thought to have a propensity for addiction.

[edit] Efficacy
The efficacy of methadone, whether for heroin addiction or chronic pain, has long been debated. Methadone is a strong opioid that induces analgesia which is indistinguishable from morphine’s and other opiate agonists. Regarding addiction, a Cochrane review (neutral organization that examines medical treatments) from 2004 noted, “Methadone is an effective maintenance therapy intervention for the treatment of heroin dependence as it retains patients in treatment and decreases heroin use better than treatments that do not utilize opioid replacement therapy. It does not show statistically significant superior effect on criminal activity.” In other words, opiate-dependent patients stayed in methadone programs, but reduction in criminal activity was no greater than that seen in patients treated without methadone.

These studies of criminal activity, however, ignore the many homeless and extremely impoverished who are in methadone programs. Such people cannot cease criminal activity because it is necessary, at least in the circumstances which they are currently in, to remain alive on a day to day basis.[citation needed] In studies of people with access to housing and jobs, the cessation of illegal opiate use (and continuance of legal opiate use) which methadone’s prescription provides reduces criminality. In methadone users who continue to use other drugs and who have access to housing and jobs, the problem lies in use of non-opiate drugs. Since methadone use is not a substitute for non-opiate use, this is to be expected.

Worldwide, there has been an explosion of deaths related to methadone. Methadone has recently come into favor because of its morphine-equivalent analgesia and the longer half-life of methadone which makes blood levels and thus analgesia more stable in patients. Germany noted that one-half of its drug-related deaths were caused in whole or in part by methadone. In 1996, more than twice as many people died from methadone as died from heroin in England. It should be noted that many overdose deaths involving methadone were caused by concurrent use of benzodiazepines or other sedative drugs such as alcohol.[citation needed]Relatives of the deceased also report that many who died had solely consumed methadone. Methadone is thought to cause cardiac conduction problems leading to arrest more often than is recorded (Medsafe).
