Benefits of NAROPIN® vs Bupivacaine
Why Choose NAROPIN?
NAROPIN offers several advantages when compared with bupivacaine including faster return of motor function,1-8 effective sensory block,1-5,8,9 opioid reduction,10-13 improved safety and tolerability,11,13-17 and greater patient satisfaction.10,18
- Faster return of motor function1-8

delivery6,7
- -More spontaneous vaginal deliveries7,11
- -Significantly fewer instrumented deliveries6,7,11
- Faster return of motor function following
caesarean sections2,3
- 5.6 to 9.6 hours faster for lower arm surgery4
- 8 to 10 hours faster for total knee replacement8
- Similar onset and duration, and effective sensory block1-5,8,9
- Significant reduction in the need for opioids10-13
- 57% fewer intraoperative requests for
opioids vs bupivacaine10
- Significantly better cardiovascular and CNS profile11,14,15
