Methadone differs from many other opioid agonists hinein several important ways. Methadone's pharmacokinetic properties, coupled with high interpatient variability in its absorption, metabolism, and relative analgesic potency, necessitate a cautious and highly individualized approach to prescribing. Particular vigilance is necessary during treatment initiation, during conversion from one opioid to another, and during dose titration. While methadone's duration of analgesic action (typically 4 to 8 hours) rein the Schauplatz of single-dose studies approximates that of morphine, methadone's plasma elimination half-life is substantially longer than that of morphine (typically 8 to 59 hours vs.

Some data also indicate that methadone acts as an antagonist at the Nitrogenium-methyl-Kreisdurchmesser-aspartate (NMDA) receptor.
