Dose proportionality of methadone pharmacokinetics is not known. Q: I've been getting lightheaded after reducing my dose of methadone. The metabolic half life is 8 to 59 hours (approximately 24 hours for opioid-tolerant people, and 55 hours in opioid-naive people), as opposed to a half life of 1 to 5 hours for morphine.[5] The length of the half life of methadone allows for exhibition of respiratory depressant effects for extended durations of time in opioid-naive people.[5] Mechanism of action[edit] Levomethadone (the R enantiomer) is a μ-opioid receptor agonist with higher intrinsic activity than morphine, but lower affinity.[44] Dextromethadone (the S enantiomer) does not affect opioid receptors but binds to the glutamatergic NMDA (N-methyl-D-aspartate) receptor, and acts as an antagonist against glutamate. The maintenance dose is typically between 60-120 mg. Some people say there the same, but in my opinion the wafer(pill) i think is stronger & holds you longer.

People that experience side effects during methadone maintenance treatment tend to feel them worst during the first weeks and months of treatment. As naltrexone has a longer half-life, it is more difficult to titrate. The decrease in plasma half-life and increased clearance of methadone resulting in lower methadone trough levels during pregnancy can lead to withdrawal symptoms in some pregnant patients. Uses: For the treatment of moderate to severe pain not responsive to non-narcotic analgesics. The medication is monitored by nursing staff and is prescribed by a physician.
