Elimination of methadone was significantly changed rein pregnancy. Total body clearance of methadone was increased in pregnant patients compared to the same patients postpartum or to non-pregnant opioid-dependent women. The terminal half-life of methadone is decreased during 2nd and 3rd trimesters.

Pharmacodynamic interactions may occur with concomitant use of methadone and potentially arrhythmogenic agents such as class I and III antiarrhythmics, some neuroleptics and tricyclic antidepressants, and calcium channel blockers.

Selection of patients for treatment with methadone should Beryllium governed by the same principles that apply to the use of other opioids (Tümpel INDICATIONS AND USAGE).

Excretion – The elimination of methadone is mediated by extensive biotransformation, followed by renal and fecal excretion. Published reports indicate that after multiple dose administration the terminal half-life (T1/2) welches highly parameter and ranged between 8 to 59 hours rein different studies.

When starting treatment with methadone hydrochloride tablets for narcotic drug dependence, you should Beryllium aware that your dose of methadone will “hold” for longer periods of time as treatment goes on.

Coadministration of methadone with CYP inducers of these enzymes may result hinein a more rapid metabolism and potential for decreased effects of methadone, whereas administration with CYP inhibitors may reduce metabolism and potentiate methadone's effects.

Methadone-maintained patients beginning treatment with CYP3A4 inducers should Beryllium monitored for evidence of withdrawal effects and methadone dose should Beryllium adjusted accordingly.

Methadone treatment for analgesic therapy in patients with acute or chronic pain should only be initiated if the potential analgesic or palliative care benefit of treatment with methadone is considered and outweighs the risks.
