Monoamine Oxidase (MAO) Inhibitors – Therapeutic doses of meperidine have precipitated severe reactions hinein patients concurrently receiving monoamine oxidase inhibitors or those who have received such agents within 14 days. Similar reactions thus far have not been reported with methadone.

When treating pain, methadone given on a fixed-dose schedule may have a narrow therapeutic Stichwortverzeichnis rein certain patient populations, especially when combined with other drugs, and should Beryllium reserved for cases where the benefits of opioid analgesia with methadone outweigh the known potential risks of cardiac conduction abnormalities, respiratory depression, altered mental states and postural hypotension.

Clinical Pharmacology for Pregnancy – Pregnant women appear to have significantly lower trough plasma methadone concentrations, increased plasma methadone clearance, and shorter methadone half-life than after delivery.

Zidovudine – Experimental evidence demonstrated that methadone increased the area under the concentration-time curve (AUC) of zidovudine which could result hinein toxic effects.

Abuse and addiction are separate and distinct from physical dependence and tolerance. Physicians should Beryllium aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence hinein all addicts. Rein addition, abuse of opioids can occur rein the absence of true addiction and is characterized by misuse for non-medical purposes, often rein combination with other psychoactive substances.

Tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia (hinein the absence of disease progression or other external factors).

Patients initiating treatment with methadone for opioid dependence should Beryllium reassured that the dose of methadone will “hold” for longer periods of time as treatment progresses.

Initial doses should Beryllium lower for patients whose tolerance is expected to Beryllium low at treatment entry. Loss of tolerance should Beryllium considered rein any patient who has not taken opioids for more than 5 days.

The relative potency estimate used to calculate an equianalgesic starting methadone dose, rein particular, whether it is intended for use hinein acute or chronic methadone dosing;

Methadone should be administered with particular caution to patients already at risk for development of prolonged QT interval (e.g., cardiac hypertrophy, concomitant diuretic use, hypokalemia, hypomagnesemia). Careful monitoring is recommended when using methadone rein patients with a history of cardiac conduction abnormalities, those taking medications affecting cardiac conduction, and in other cases where history or physical exam suggest an increased risk of dysrhythmia. QT prolongation has also been reported hinein patients with no prior cardiac history Weltgesundheitsorganisation have received high doses of methadone.
