LNP is new extended release (ER) oily solution formulation of ropivacaine that is intended for local infiltration into surgical wounds. The formulation is designed to slowly release the ropivacaine over 36-72 hours. By providing local analgesia over a long time span, the need for systemic analgesics is expected to be reduced and hospital stays may be shortened. The purpose of this study is to determine the ease of usage and administration of LNP in the surgical setting, to follow the PK profile of LNP over 72 hours and evaluate the duration of analgesia witnessed in the surgical setting.

Primary Outcome Measures:
  • Evaluate the safety of LNP when administrated in a surgical setting [ Time Frame: 72 hours ] [ Designated as safety issue: Yes ]
    All AE's reported by the subjects will be recorded

Secondary Outcome Measures:
  • Evaluated the plasma PK profile of LNP [ Time Frame: 72 hours ] [ Designated as safety issue: Yes ]
    Blood samples will betaken for evaluation of plasma ropivacaine levels

Other Outcome Measures:
  • Evaluate the duration of analgesia witnessed in the surgical setting [ Time Frame: 72 hours ] [ Designated as safety issue: No ]
    Pain scales and questioners will be used to evaluate the pain intensity following the surgical procedure

Estimated Enrollment: 30
