Methadone - in addition to being used in pain therapy - is also used in the treatment of drug addiction to reduce the typical symptoms of withdrawal symptoms.
Methadone is available in pharmaceutical formulations suitable for both oral and parenteral administration.
From a chemical point of view, methadone can be considered as a derivative of diphenylpropylamine.
Methadone-based medicines for parenteral use and other than those for oral use are reserved for hospital use only, while others can be sold in pharmacies, but only upon presentation of a specific medical prescription (ministerial model with tracing or SSN recipe book with data annotation buyer). These medicines are for oral use and are classified as class A drugs, therefore, their cost can be reimbursed by the National Health System (SSN).
