amide and ester local anesthetics

Amide-type local anesthetics compared to ester-type anesthetics are more commonly used due to their better pharmacokinetic properties and lower incidence of adverse effects [1R].

What is the difference between esters and amides?

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?

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 the difference between amide and ester local anesthetics?

Amides are biotransformed in the liver but esters are hydrolyzed in the bloodstream by plasma esterases.
Ester local anesthetics are no longer packaged in dental cartridges and are used infrequently, with the exception of benzocaine, found in several topical anesthetic preparations.

Commonly used ester LAs include chloroprocaine, procaine, and tetracaine. The commonly used amide LAs include lidocaine, bupivacaine, ropivacaine, mepivacaine, and outside the United States, levobupivacaine. Articaine is an amide LA used primarily in dentistry.
