Due to methadone’s totally synthetic structure (man made chemical), its pharmacological effects are longer lasting than those of other opiate drugs, allowing for once-daily administration in pain management and opiate
treatment programs such as
methadone clinics. However, the pain-relieving effects are shorter than the pharmacological half-life, so that dosing for pain control usually requires multiple doses per day. Depending on its form, Methadone can also be known as Dimepheptanol.
