Which opiate is often prescribed for pain management?

Morphine is a well-established and commonly prescribed opiate for pain management, particularly in hospital settings or for chronic pain management. It is a potent analgesic that acts directly on the central nervous system to relieve moderate to severe pain.

Heroin, while an opiate, is not prescribed for pain management due to its high potential for abuse and addiction, as well as its illegal status in many places. Fentanyl, another powerful opiate, is indeed used for pain management and is frequently prescribed in clinical settings, especially for severe pain or in patients with opioid tolerance. However, it is often considered alongside other treatment options and is typically used with caution due to its potency.

While the listed options include both morphine and fentanyl, the primary and most traditional option for routine pain management remains morphine, making it the best answer in this context.
