Background:
(-)-Ropivacaine-d7is intended for use as an internal standard for the quantification of (-)-ropivacaine by GC- or LC-MS. (-)-Ropivacaine is a potent and reversible blocker of sodium channels in nerve fibers.1In vivo, (-)-ropivacaine induces complete impairment of proprioception, motor function, and nociception in the hindleg of rats when 100 μL of an 8 mM solution is injected percutaneously into the sciatic nerve.2(-)-Ropivacaine depresses myocardial contractile force in isolated rat hearts less potently than (±)-ropivacaine, as well as (-)- and (±)-bupivacaine .3Formulations containing (-)-ropivacaine have been used as local anesthetics during surgery and childbirth.
