Flashcards
Topical Anesthesia
Topical Anesthesia
Benzocaine is frequently used for topical anesthesia due to its ability to numb the surface tissues when applied directly.
Metabolizing Enzyme
Metabolizing Enzyme
Pseudocholinesterase is the enzyme responsible for metabolizing ester-type local anesthetics in the plasma.
Lidocaine Metabolism
Lidocaine Metabolism
Lidocaine, an amide-type local anesthetic, is metabolized in the liver by the cytochrome P450 enzyme system.
