Description:   Ropivacaine is an aminoamide local anaesthetic drug commonly marketed by AstraZeneca under the trade name Naropin. Naropin was launched in 1996 in Australia, Denmark, Finland, the Netherlands and Sweden as a local anesthetic. It can be prepared in a number of ways the most efficient involves a three step sequence beginning with L-pipecolic acid. This compound is the first one in this family to be produced as the pure (S)- enantiomer. The (R)-enantiomer has been shown to have cardiotoxic effects. Thus ropivicaine has less cardiovascular and CNS toxicity than bupivacaine. It is a Na channel blocker that is specific for affecting nerve fibers responsible for transmission of pain (Aδ and C) with no effect on fibers responsible for motor function (Aβ). Clinically, it has distinct advantages over bupivacaine. Its effects are slower in onset, less intense and have a shorter duration. This is a result of extensive metabolism in the liver to the 3-hydroxy isomer by CYPIA2 isoenzyme.
Ropivacaine is an anesthetic (numbing medicine) that blocks the nerve impulses that send pain signals to your brain.
Ropivacaine is used as a local (in only one area) anesthesia for a spinal block, also called an epidural. The medication is used to provide anesthesia during a surgery or C-section, or to ease labor pains.
