Safety and Tolerability
Significantly fewer cardiovascular side effects1,2
- Less depression of cardiac conductivity
- Significantly higher dose of NAROPIN tolerated vs bupivacaine

Lower risk of systemic toxicity than bupivacaine1-3
In labor and delivery, serious maternal cardiotoxicity has been reported after inadvertent i.v. bupivacaine administration, which may lead to treatment-resistant cardiac arrest.4
- NAROPIN has a shorter systemic half-life than bupivacaine, which makes it safer for repeated doses3
- The maximum tolerated concentration of NAROPIN (unbound arterial plasma concentrations at the end of infusion) is twice as high as that of bupivacaine (P<0.001)2
NAROPIN has a more favorable pregnancy category (Category B) vs bupivacaine (Category C)5,6
Severity and frequency of symptoms were greater with bupivacaine1,2

NAROPIN is indicated for the production of regional or local anesthesia for surgery and for acute pain management.
