Question 10

Most local anesthetics contain a tertiary amine group. This specific functional group is critical for which aspect of their mechanism of action?

Accepted Answer

B. Allowing the drug to exist in an ionized form that can bind to intracellular sodium channels. — The tertiary amine group in local anesthetics allows them to be protonated (ionized) at physiological pH. While the uncharged form crosses the neuronal membrane, the intracellular charged form is essential for binding to the voltage-gated sodium channels from the inside, thereby blocking nerve impulse transmission. The amide linkage, not the tertiary amine, is responsible for resistance to esterase metabolism, and the overall structure is designed for membrane penetration.

Answer

A. Increasing the overall lipophilicity of the drug molecule.

Answer

C. Preventing their metabolism by plasma esterases or hepatic enzymes.

Answer

D. Enhancing the drug's ability to remain in the extracellular space.
