Levobupivacaine (Chirocaine, (S)-(-)-Bupivacaine, L-(-)-Bupivacaine), the S (-)-enantiomer of bupivacaine, is a long-acting amide local anaesthetic used in analgesia and anaesthesia. Levobupivacaine exhibits effects on motor and sensory nerves by inhibiting the opening of voltage-gated sodium channels.
