(±)-Methadone is a synthetic opioid used primarily for pain management and as part of drug addiction detoxification programs. It is classified as a racemic mixture, containing equal parts of two enantiomers, which contributes to its pharmacological effects. The substance acts primarily as a mu-opioid receptor agonist, providing analgesic effects, while also exhibiting NMDA receptor antagonism, which may help in reducing opioid tolerance. Methadone has a long half-life, allowing for once-daily dosing in maintenance therapy, which is beneficial for patients in opioid dependence treatment. It is soluble in organic solvents but has limited solubility in water, which influences its formulation and administration routes. Side effects can include respiratory depression, sedation, and potential for dependence, necessitating careful monitoring during use. Due to its potency and risk of overdose, methadone is classified as a controlled substance in many jurisdictions, highlighting the importance of responsible prescribing and usage practices.
