Cocaine = Soluble Lignocaine = Soluble Benzocaine = Insoluble Oxethazaine = Insoluble
Match the following properties with Ester LAs or Amide LAs:
Short duration = Ester LAs Longer duration = Amide L As Less intense analgesia = Ester LAs More intense analgesia = Amide L As
Match the following hypersensitivity risk with the respective type of local anesthetic:
High risk = Ester LAs Low risk = Amide L As Hydrolyzed by plasma = Ester LAs Metabolized in the liver = Amide L As
