Methadone is a synthetic analgesic for pain. It is frequently used in maintenance programs as a substitute for heroin or other abused opiates, while allowing the subject to successfully participate in drug rehabilitation. It suppresses opiate withdrawal symptoms, allowing the patients to function well and perform tasks competently. Recreationally, it is abused for its sedative and analgesic effect.
