Which statement accurately describes methadone?

• A. It has the same effects as opiate narcotics and is derived from opium
• B. It has the same effects as opiate narcotics but is not derived from opium or morphine
• C. It has no analgesic effects
• D. It acts as a stimulant

Answer: (B)

Methadone is a synthetic opioid that produces effects similar to other opiate narcotics because it activates the same μ-opioid receptors in the brain, giving analgesia and the classic opioid effects (euphoria, sedation, respiratory depression) at appropriate doses. It is not derived from opium or morphine, which is why it’s described as synthetic rather than opium-derived. It is not a stimulant; opioids depress CNS activity. Methadone does have analgesic properties and is widely used for pain management and for opioid dependence treatment because of its long duration of action, but its origin is synthetic, not from opium.
