Which class is used to treat severe pain and may be habit forming in high doses over prolonged time?

• A. General anesthetic
• B. Analgesics (Class)
• C. Analgesic narcotics
• D. Analgesic anti-inflammatories

Answer: (C)

Opioid analgesics are potent medicines used for severe, persistent pain, but they come with a real risk of dependence and tolerance when used in high doses for a long time. Their strong analgesic effect is due to action on opioid receptors in the brain and spinal cord, which provides substantial relief but can lead to craving and withdrawal if use is stopped abruptly or continued beyond needs. That combination—effective relief for severe pain plus a high potential for habit formation with prolonged, high-dose use—is why this class fits best.

General anesthetics are for surgery and induce loss of consciousness, not long-term pain control. The broader category of analgesics includes many non-opioid drugs that are not typically habit-forming and may be insufficient for severe chronic pain. Analgesic anti-inflammatories (NSAIDs) relieve pain and inflammation but carry little risk of dependence, and they’re not the primary choice for managing severe, ongoing pain in many patients.
