The prescribed opioid pain regimen is 80-100 times more potent than which medication?

Morphine is the reference standard for opioid potency. Fentanyl is 80-100 times more potent than morphine. This makes fentanyl extremely dangerous — small amounts can cause fatal respiratory depression. Hydromorphone is 5-7x stronger than morphine. Meperidine is ~0.1x (weaker). Codeine is 0.1-0.15x. Morphine = the opioid benchmark.
