Methadone's pharmacokinetic properties, coupled with high interpatient variability hinein 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) in the Drumherum 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.

Most commonly, clinical stability is achieved at doses between 80 to 120 mg/day.
Hinein these patients, even usual therapeutic doses of methadone may decrease respiratory drive while simultaneously increasing airway resistance to the point of apnea. Alternative, non-opioid analgesics should be considered, and methadone should Beryllium used at the lowest effective dose and only under careful medical supervision.
