Opioid peptides are short sequences of amino acid s that bind to opioid receptor s in the brain opiate s and opioid s mimic the effect of these peptides. Opioid peptides may be produced by the body itself, for example endorphin s. The effects of these peptides vary, but they all resemble opiates. Brain opioid peptide systems are known to play an important role in motivation, emotion, attachment theory attachment behaviour , the response to stress and pain, and the control of food intake. Opioid like peptides may also be absorbed from partially digestion digested food casomorphin s, Gluten exorphin exorphins , and rubiscolin s , but have limited physiological activity. The opioid food peptides have lengths of typically 4 8 amino acids. The body s own opioids are generally much longer.

Unreferenced date December 2009 Opioid Agonist Treatment , or OAT , refers to the treatment of a narcotics Substance dependence addiction in humans via the administration of similar opioid drugs, agonists , and the resultant cross tolerance and physical dependence. Methadone and Buprenorphine are the most common drugs used in agonist treatment. Methadone is a full opioid agonist and so is the preferred treatment in heroin addiction as it creates a feeling of euphoria, though not as strong as from taking heroin. Buprenorphine is a partial opioid agonist and has virtually no withdrawal effects making it very desirable as a treatment. However, the high from Buprenorphine is also reduced leading to addicted individuals preferring methadone treatment. Only facilities accredited by CSAT are able to provide this service. The use of agonist drugs to treat a narcotics addiction is tightly regulated in the United States . Diversion, or potential diversion, of agonist drugs is often the domain of the Drug Enforcement Administration , as they are defined as criminal acts.

Opioid replacement therapy ORT is the medical procedure of replacing an Law illegal opioid drug abuse drug such as heroin with a longer acting but less euphoric opioid, usually methadone or buprenorphine , that is taken under medical supervision. In some countries e.g. Switzerland, Austria patients may be treated with slow release morphine where methadone is deemed inappropriate in the circumstances. In Germany, Dihydrocodeine has been used off label in ORT for many years, however it is no longer frequently prescribed for this purpose. Extended release dihydrocodeine is again in current use in Austria for this reason. Research into the usefulness of piritramide , extended release hydromorphone including polymer implants lasting up to 90 days, dihydroetorphine and some other drugs for this purpose is in various stages in a number of countries at present. The prescription of medicinal heroin or morphine for long term addicts, particularly those having difficulty with methadone programmes, is also done in some countries. Some formulations of buprenorphine are manufactured in Tablet pill form with the opiate antagonist Naloxone to prevent drug addiction addicts from crushing the tablets and injecting them instead of taking them sublingual ly under the tongue . The driving principle behind ORT is that an opiate addict will be able to regain a normal life and schedule while being treated with a substance that stops him from experiencing withdrawal symptoms and Craving withdrawal drug cravings , but doesn t provide strong euphoria.
