<prompt> False about ropivacaineLess cardiotoxic than bupivacaineMore cardiotoxic than lignocaineContains only R enantiomerOnset of action is faster than bupivacaine  <response>: 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.
