Ropivacaine hydrochloride Usage And Synthesis

Description

(–)-Ropivacaine is a potent and reversible blocker of sodium channels in nerve fibers. In 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. (–)-Ropivacaine depresses myocardial contractile force in isolated rat hearts less potently than (±)-ropivacaine, as well as (–)- and (±)-bupivacaine . Formulations containing (–)-ropivacaine have been used as local anesthetics during surgery and childbirth.

Chemical Properties

White Solid

Uses

Ropivacaine hydrochloride monohydrate has been used as an analyte in tandem mass spectrometry and as an amide-based local anaesthetic to test its effect on breast cancer cell methylation.

Uses

Anesthetic (local).

Definition

ChEBI: The monohydrate form of (S)-ropivacaine hydrochloride.

General Description

Ropivacaine has lidocaine-related structure with tertiary amine side chains.?It is a pure S(-)enantiomer with a propyl group on the piperidine nitrogen atom.

Biochem/physiol Actions

Local anaesthetic with less cardiotoxicity than bupivacaine; causes reversible blockade of impulse propagation along nerve fibres by preventing the inward movement of sodium ions through the cell membrane of the nerve fibers.
