The name ropivacaine refers to both the [[racemate]] and the marketed ''S''-[[enantiomer]]. '''Ropivacaine hydrochloride''' is commonly marketed by [[AstraZeneca]] under the [[trade name]] '''Naropin'''. ==History== Ropivacaine was developed after [[bupivacaine]] was noted to be associated with [[cardiac arrest]] in 0.5–0.75% of cases, particularly in pregnant women. Ropivacaine was found to have less cardiotoxicity than bupivacaine in animal models. ==Clinical use== ===Indications=== Ropivacaine is indicated for local anaesthesia including infiltration, [[nerve block]], [[epidural]] and [[intrathecal]] anaesthesia in adults and children over 12 years. It is also indicated for peripheral nerve block and [[caudal]] epidural in children 1–12 years for surgical pain. It is also sometimes used for infiltration anaesthesia for surgical pain in children. Ropivacaine is often co-administered with [[fentanyl]] for epidural [[analgesia]], for example in pregnant women during [[Childbirth|labour]]. ===Contraindications=== Ropivacaine is contraindicated for IV regional anaesthesia (IVRA). ===Adverse effects=== [[Adverse drug reaction]]s (ADRs) are rare when it is administered correctly. Most ADRs relate to administration technique (resulting in systemic exposure) or pharmacological effects of anesthesia, however [[allergy|allergic]] reactions can rarely occur. Systemic exposure to excessive quantities of ropivacaine mainly result in [[central nervous system]] (CNS) and [[cardiovascular]] effects – CNS effects usually occur at lower [[blood plasma]] concentrations and additional cardiovascular effects present at higher concentrations, though cardiovascular collapse may also occur with low concentrations. CNS effects may include CNS excitation (nervousness, tingling around the mouth, [[tinnitus]], tremor, dizziness, blurred vision, [[seizure]]s) followed by depression (drowsiness, loss of consciousness, [[respiratory depression]] and [[apnea]]). Cardiovascular effects include [[hypotension]], [[bradycardia]], [[arrhythmia]]s, and/or [[cardiac arrest]] – some of which may be due to [[Hypoxia (medical)|hypoxemia]] secondary to respiratory depression.<ref name="AMH2006">Rossi S, editor.
