Morphine Equivalents Visualized

My day job involves the creation of visualization software to help engineers evaluate complex systems. In my last post detailing Morphine Equivalents there was math, and numbers, and eyes glazing. So, as an aide to the previous post I submit to you a graph of the three narcotic dosing schedules. I pulled the half-lives from Wikipedia and assumed a bioavailability of 100% for the IV route.

The half-lives used are:
  • Morphine: 2-3 hours
  • Fentanyl: 2-4 hours
  • Dilaudid: 2-3 hours
