Mutagenesis – There are several published reports on the potential genetic toxicity of methadone. Methadone tested negative rein tests for chromosome breakage and disjunction and sex-linked recessive lethal gene mutations in germ cells of Drosophila using feeding and injection procedures.
The initial methadone dose should Beryllium carefully titrated to the individual. Too rapid titration for the patient's sensitivity is more likely to produce adverse effects.
Since the metabolism of methadone is mediated primarily by CYP3A4 isozyme, coadministration of drugs that inhibit CYP3A4 activity may cause decreased clearance of methadone. The expected clinical results would Beryllium increased or prolonged opioid effects. Thus, methadone-treated patients coadministered strong inhibitors of CYP3A4, such as azole antifungal agents (e.

The severity of this syndrome will depend on the degree of physical dependence and the dose of the antagonist administered.

Some data also indicate that methadone acts as an antagonist at the Nitrogenium-methyl-D-aspartate (NMDA) receptor. The contribution of NMDA receptor antagonism to methadone's efficacy is unknown. Other Diskreter Versand von Methadontabletten NMDA receptor antagonists have been shown to produce neurotoxic effects in animals.
Although with single-dose administration the onset and duration of analgesic action, as well as the analgesic potency of methadone and morphine, are similar methadone's potency increases over time with repeated dosing. Furthermore, the conversion ratio between methadone and other opiates varies dramatically depending on baseline opiate (morphine equivalent) use as shown hinein the table below.
Laboratory studies, both hinein vivo and rein vitro, have demonstrated that methadone inhibits cardiac potassium channels and prolongs the QT interval. Cases of QT interval prolongation and serious arrhythmia (torsades de pointes) have been observed during treatment with methadone. These cases appear to be more commonly associated with, but not limited to, higher dose treatment (> 200 mg/day). Most cases involve patients being treated for pain with large, multiple daily doses of methadone, although cases have been reported hinein patients receiving doses commonly used for maintenance treatment of opioid addiction.
