[PDF] amide and ester local anaesthetics

Clinical Tips. Amide local anesthetics (e.g., lidocaine, mepivacaine, bupivacaine, ropivacaine) are most commonly used and are metabolized primarily by the liver. Most ester local anesthetics are metabolized by pseudocholinesterases in the blood.

  • What is the difference between ester and amide in local anesthesia?

    Esters are hydrolyzed by plasma esterases, whereas amides are biotransformed in the liver.
    Esters are no longer packaged in dental cartridges and are used infrequently with the exception of benzocaine, which is found in several topical anesthetic preparations.

  • What are the list of ester and amide local anesthetics?

    There are 2 classes of local anesthetics, amides and esters.
    Esters include benzocaine, chloroprocaine, cocaine, procaine, proparacaine, and tetracaine.
    The amides include articaine, bupivacaine, levobupivacaine, dibucaine, etidocaine, mepivacaine, prilocaine, ropivacaine, and finally, lidocaine.

  • What is an ester local anesthetic?

  • What is an ester local anesthetic?
