The plasma therapeutic level of methadone is approximately 100-400 μg · l-1 (micrograms/liter) and the toxic plasma level is about 1,000 to 2,000 μg · l-1 (micrograms/liter).

Metabolism
Methadone 20mg is mainly metabolized in the liver by mono- and di-N-demethylation and then spontaneously converts to a cyclic structure, on the one hand, 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine (EDDP, Methadone primary metabolite) and 2-ethyl-5-methyl-3,3-diphenylpyrrolidine (EMDP, secondary metabolite) on the other hand. Methadone is also metabolized by hydroxylation to methadol, followed by N-demethylation to normethadol. Methadone, EDDP, and EMDP also undergo hydroxylation followed by glucuronidation. The major metabolites of methadone are inactive

Substitution Treatments

In a 2011 survey of 292 clinical experts in Scotland, methadone was ranked 12th for personal injury and 10th for societal harm on 19 current recreational drugs3.
Main article: Opiate substitution treatment.
Introduced into the United States in the 1960s by Dole and Nyswander4, they were first used for serious heroin addicts, such as for soldiers returning from Vietnam.

The aim of the medication is to substitute the consumption of opiates for a euphoric effect (heroin, morphine and certain analgesics) to help the person stabilize his cravings5. Together with medico-social care in the context of a withdrawal cure, methadone treatment aims to stabilize the person’s addiction and harm reduction. The aim of this medicalization is to reduce the risks inherent in drug use: the risks associated with the injection of intravenous substances or nasal administration (including HIV and hepatitis C), risks Overdose or overdose, and risks associated with illegal activities to obtain heroin (deal, prostitution). Moreover, when a person is under methadone treatment, they will experience virtually no euphoria if they consume heroin. This discourages many consumers from relapsing. The introduction of medication can be an integral part of a global process of abstinence.

Methadone 20mg has the advantage of being a long-acting opiate, preventing the sensation of lack and relapse of heroin use. It is taken orally, in one dose per 24h and in some cases two doses per 24h for short “metabolizers”, in the form of a bitter and non-injectable solution, capsules or suppositories. In general, the syrup is in the liquid formula of 1% methadone hydrochloride: 1 ml of solute represents 10 mg of methadone hydrochloride.

Medical recommendations indicate a usual maximum daily dose of 60 mg per 24 h6. Studies in Switzerland have shown that some patients require higher doses of 80 mg, 200 mg or 250 mg at the start of treatment 7. The maximum dose prescription may be limited by the laws on the supply of psychotropic substances depending on the country.
