What is the difference between levobupivacaine and bupivacaine?
Levobupivacaine is the s-isomer of racemic Bupivacaine. It is less cardio, neurotoxic and equally potent local anaesthetic compared to its racemate. It is known to cause less Depression of myocardial contractility. Dexmeditomidine when used via epidural route has synergistic effect with local anaesthetics.
Why is levobupivacaine (( S )- bupivacaine preferred clinically to Racaemic bupivacaine?
Levobupivacaine is a single-enantiomer preparation consisting of the S enantiomer of bupivacaine. Compared with racemic bupivacaine, levobupivacaine has considerably reduced CNS and cardiovascular toxicity, allowing a larger dose to be given.
