In spite of methadone's Considerably longer duration of action compared to possibly heroin and other shorter-acting agonists and the need for repeat doses with the antagonist naloxone, it is still used for overdose therapy. As naltrexone has a longer half-life, it really is more difficult to titrate. If too significant a dose of your opioid antagonist is given to a dependent human being, it will end in withdrawal symptoms (perhaps serious).
