Background
- Class of analgesic medications that act primarily on the μ-opioid receptor
Morphine Milligram Equivalent Dose
Drug | MME per mg PO | MME per mg IV/SC |
---|---|---|
Meperidine | 0.1 | — |
Codeine | 0.15 | — |
Morphine | 1 | 2 |
Oxycodone | 1.5 | — |
Methadone | 3 | — |
Hydromorphone | 5 | 10 |
Fentanyl | 200 MME per 50 mcg/h transdermal |
Fentanyl
Fentanyl mcg/h | MME |
---|---|
25 | 60-134 |
37 | 135-179 |
50 | 180-224 |
62 | 225-269 |
75 | 270-314 |
87 | 315-359 |
100 | 360-404 |
- IV is essentially twice as strong as PO
