Background and Objective: Regarding inefficiency of common drugs used for alleviation of anxiety due to narcotics withdrawal, the present study was evaluated methadone and haloperidol co-drugs therapy on anxiety due to morphine withdrawal. Materials and Methods: Ninety eight NMRI male mice were divided into acute and chronic experimental groups. Then, each group was divided into 7 subgroups: sa...

Hepatitis C virus (HCV) antibody is present in most patients enrolled in methadone maintenance programs. Therefore, interactions between the HCV protease inhibitor telaprevir and methadone were investigated. The pharmacokinetics of R- and S-methadone were measured after administration of methadone alone and after 7 days of telaprevir (750 mg every 8 h [q8h]) coadministration in HCV-negative sub...

INTRODUCTION Methadone, the most widely delivered maintenance therapy for heroin addicts, may be responsible for life-threatening poisonings with respiratory depression. The toxicokinetics and the toxicokinetic/toxicodynamic (TK/TD) relationships of methadone enantiomers have been poorly investigated in acute poisonings. The aim of this study was to describe the relationships between methadone-...

BACKGROUND Methadone maintenance therapy (MMT) is a mainstay for treating opioid use disorder and preventing and managing HIV among people who inject drugs (PWID). While previous research suggested low dosing of methadone and high rates of discontinuation of MMT among PWID in Thailand, little is known about patients' lived experiences with MMT in this setting. Therefore, we conducted a mixed-me...

Methadone maintenance therapy has been used as one of the possible ways to prevent of infection diseases such as HIV and hepatitis B and C and improve the quality of life in opioid-dependent patients. OBJECTIVES The aim of this study was to assess the anthropometric and socio...

BACKGROUND The pharmacokinetics of methadone is altered during pregnancy, but the most appropriate dosing and monitoring regimen has yet to be identified. OBJECTIVE To review dosing and monitoring of methadone therapy in pregnancy. METHODS A literature search was performed in several databases (PubMed, MEDLINE, Embase, International Pharmaceutical Abstracts, and the Cochrane Database of Sys...
