Methadone (Methadone Hydrochloride) - Summary

 
 



BOX WARNING

NOTE

If methadone is administered for treatment of heroin dependence for more than 3 weeks, the procedure passes from treatment of the acute withdrawal syndrome (detoxification) to maintenance therapy. Maintenance treatment is permitted to be undertaken only by approved methadone programs. This does not preclude the maintenance treatment of an addict who is hospitalized for medical conditions other than addiction and who requires temporary maintenance during the critical period of his/her stay or whose enrollment has been verified in a program approved for maintenance treatment with methadone.

Published Studies Related to Methadone

Tramadol versus methadone for treatment of opiate withdrawal: a double-blind, randomized, clinical trial. [2012]
The aim of this study was to compare the efficacy and safety of tramadol versus methadone for treatment of opiate withdrawal. Seventy patients randomly were assigned in two groups to receive either prescribed methadone (60 mg/day) or tramadol (600 mg/day)... Tramadol may be as effective as methadone in the control of withdrawal and could be considered as a potential substitute for methadone to manage opioids withdrawal.

Rationale and design of a randomized controlled trial of directly observed hepatitis C treatment delivered in methadone clinics. [2011.11.12]
ABSTRACT: BACKGROUND: Most methadone-maintained injection drug users (IDUs) have been infected with hepatitis C virus (HCV), but few initiate HCV treatment...

Randomized Trial of Standard Methadone Treatment Compared to Initiating Methadone without Counseling: 12-month Findings. [2011.10.26]
Aims: This study aimed to determine the relative effectiveness of 12-months of Interim Methadone (IM; supervised methadone with emergency counseling only for the first 4 months of treatment), Standard Methadone treatment (SM; with routine counseling) and Restored Methadone treatment (RM: routine counseling with smaller caseloads)...

Trazodone for sleep disturbance during methadone maintenance: A double-blind, placebo-controlled trial. [2011.07.26]
BACKGROUND: To test whether trazodone, one of the most commonly prescribed medications for treatment of insomnia, improves subjective and/or objective sleep among methadone-maintained persons with sleep complaints, we performed a randomized, double-blind, placebo-controlled trial with 6-month follow-up... CONCLUSIONS: Trazodone did not improve subjective or objective sleep in methadone-maintained persons with sleep disturbance. Other pharmacologic and non-pharmacologic treatments should be investigated for this population with high rates of insomnia. Copyright (c) 2011 Elsevier Ireland Ltd. All rights reserved.

Client satisfaction among participants in a randomized trial comparing oral methadone and injectable diacetylmorphine for long-term opioid-dependency. [2011.07.26]
BACKGROUND: Substitution with opioid-agonists (e.g., methadone) has shown to be an effective treatment for chronic long-term opioid dependency. Patient satisfaction with treatment has been associated with improved addiction treatment outcomes. However, there is a paucity of studies evaluating patients' satisfaction with Opioid Substitution Treatment (OST). In the present study, participants' satisfaction with OST was evaluated at 3 and 12 months. We sought to test the relationship between satisfaction and patients' characteristics, the treatment modality received and treatment outcomes... CONCLUSIONS: The higher satisfaction among those receiving medically prescribed injectable diacetylmorphine (or hydromorphone) supports current evidence regarding the attractiveness of this treatment for long-term, opioid-dependent individuals not benefiting sufficiently from other treatments. In addition, the measurement of treatment satisfaction provides valuable information about participants at risk of relapse and in need of additional services. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00175357.

Clinical Trials Related to Methadone

Co-Administration Of Fosamprenavir With Methadone: A Drug Interaction Study. [Completed]
To assess the combined effects of fosamprenavir 700mg BID + ritonavir 100mg BID + standardized dose of methadone, on plasma total and unbound methadone enantiomer pharmacokinetics (PK), opiate pharmacodynamic (PD) measures, and safety. The effect of methadone on plasma amprenavir PK will also be assessed by comparison to historical control data.

Methadone Pharmacokinetics and Cardiac Effects in Newborns [Recruiting]
The Primary objectives of this proposal are to determine the population kinetics for methadone and its enantiomers in preterm newborns and infants at 29 weeks to 48 weeks post menstrual age (PMA) who are 1 week old and older and establish any correlations of the kinetics with PMA to determine the bioavailability for enterally administered methadone in these newborns and young infants.

The secondary objectives of this proposal are to explore possible genotypic changes in CYP3A4-3A7-3A5, CYP2B6, CYP2C8, CYP2C19, and CYP2D6 and PGO on the kinetics of methadone in neonates and young infants and to test the safety of methadone in this population by correlating the plasma concentrations of the methadone enantiomers, S-methadone and R-methadone, with changes in cardiac repolarization by measurement of corrected QT, heart rate, and blood pressure.

Drug Interaction Study Of Filibuvir With Methadone, Among Subjects On Chronic Methadone Maintenance [Not yet recruiting]
Filibuvir, a CYP3A4 inhibitor is being developed for the treatment of chronic Hepatitis C infection. Given the likelihood of co administration of filibuvir and methadone, this study will evaluate the effect of filibuvir on the pharmacokinetics of R/S Methadone.

Methadone Maintenance & HIV Risk in Ukraine [Recruiting]
Treatment of opioid dependence is an important way to reduce the spread of HIV and other infectious diseases, particularly in Ukraine since intravenous opioid use is the major way these infections are being spread. This proposal will be done at the Kiev City Narcology Hospital and the City AIDS Center with collaborators from the University of Alabama and the University of Colorado. It will study the acceptability and impact of a 3-month course of methadone maintenance on 50 persons with opioid dependence, 25 who are HIV+ and 25 HIV-. The proposed work will build on a relationship that was established with the Ukrainian Co-Principal Investigator, Sergiy Dvoryak, M. D., during his Humphrey Fellowship at Johns Hopkins in 1999-2000 when he spent time with Dr. Woody and Metzger at the Penn Addiction and Treatment and Research Center. It will also extend studies of pharmacologic treatment for opioid dependence and risk reduction behavioral interventions that are being done by Drs. Woody, Schumacher and Booth in Russia and Ukraine. Primary aims are to: measure the acceptability and compliance with a 3-month course of methadone maintenance in HIV+ and HIV- patients; measure the impact of a 3-month course of methadone in reducing opioid use in HIV+ and HIV- patients; measure the impact of a 3-month course of methadone on reducing HIV risk behavior in HIV+_and HIV- patients. Secondary aims are to: assess the degree to which a 3-month course of methadone maintenance reduces illegal activities and improves employment and psychiatric symptoms; determine short-term outcome after completion of methadone treatment; and obtain pilot data on the prevalence of hepatitis B and C among study patients. This study will provide pilot data on the acceptability and efficacy of a short-term course of methadone maintenance on HIV+ and HIV- persons in a setting where this treatment has not been evaluated, on the feasibility of conducting the kind of work that is proposed, and will enhance research capabilities of Kiev investigators for future HIV prevention and treatment studies.

Methadone-Dolutegravir (DTG - GSK1349572) Drug Interaction Study. [Not yet recruiting]
Dolutegravir (DTG, GSK1349572) is an integrase inhibitor that is currently in Phase 3 clinical development for the treatment of HIV infection. As HIV-infected subjects may also be receiving methadone for opioid dependence, an evaluation of the potential interaction between DTG and methadone is warranted. The primary objective of this study is to determine whether concomitant administration of DTG can affect the pharmacokinetics (PK) of methadone. As a secondary endpoint, the PK of DTG will be compared to historical data. This study will be open-label with subjects receiving DTG and stable doses of methadone. The study will be conducted at one center in Canada in adult male and female subjects.

Methadone review by 26 year old female patient

  Rating
Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Mild Side Effects
  
Treatment Info
Condition / reason:   opiod addiction
Dosage & duration:   60mg/day taken daily for the period of monthly
Other conditions:   back pain
Other drugs taken:   none
  
Reported Results
Benefits:   It worked but then I became addicted to methadone so basically it just traded one addiction for another. I don't take as many Methedone a day as I did pain pills because Methadone is long lasting so I guess it did help me.
Side effects:   At first I got painful headaches but that subsided after continued use. I do still have horrible constipation and I have sexual dsyfuntion.
Comments:   I began recieving Methadone when I was 21 years old. I started seeing a pschiatrist because I needed help for pain pill addiction. I began getting prescriptions for hydrocodone when I was 19. I have an abnormality in my lower back which causes me severe pain. I began taking more than I was supposed to for the pain and was taking anywhere from 20 to 30 pain pills a day. So I knew I needed help. That's when my doctor gave me Methadone. He gave me 60mg a day but I usually only took 40mg depending on what I needed. Over the years I have weaned myself down to 20mg a day and everyone even my doctor says to me that I should be able to come off of these pills easily but no one understands the physical and psychological symptoms I go through. It's so hard to just stop taking them when I have became so depended on them in my daily life. I have four kids and with out them I feel like a different person and it takes everything in me to get out of bed and take care of my kids. Is it in my head? I don't know but either way, in a lot of ways it helped me but in a lot of ways it ruined my life. I don't want to be addicted to a pill for the rest of my life. Now my doctor has stopped giving them to me because he feels that I can come off them easily at such a low dose but what does he know he does not understand what it feels like. I am at such a downfall in my life, I have to buy them now just to feel normal every day. I feel like if these doctors give them to me then they should help me with the withdrawals ao I can get off them. I still need help after all these yesrs. I don't have a car to drive to a methadone clinic everyday and no one to help me. So what are people like me to do?
