difference between ester and amide local anesthetics metabolism
How are ester-type local anesthetics metabolized?
Ester-type local anesthetics are metabolized by plasma pseudocholinesterase and their metabolites are excreted through urine. 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 amide and Ester local anesthetic?
Amide and ester local anesthetics differ in their chemical stability, metabolism, and allergic potential. Amides are extremely stable, whereas esters are relatively unstable, particularly in neutral or alkaline solution. Amide compounds undergo enzymatic degradation in the liver, whereas ester compounds are hydrolyzed in plasma by esterases.
