False about ropivacaine
Ropivacaine contains only S enantiomer so cardiotoxicity is less than bupivacaine (but still higher than lignocaine). Anaesthetic propeies (onset, intensity; duration of I action) of ropivacaine are almost similar to bupivacaine.
Less cardiotoxic than bupivacaine
More cardiotoxic than lignocaine
Contains only R enantiomer
Onset of action is faster than bupivacaine
