Local Anesthetics, Amides

Class Summary

Local anesthetics are used for local pain relief.

Lidocaine (Xylocaine)

Lidocaine inhibits depolarization of type-C sensory neurons by blocking sodium channels. Topical 1% lidocaine (Xylocaine) is a commonly used anesthetic.

Ropivacaine (Naropin)

Ropivacaine decreases permeability to sodium ions in neuronal membranes. This results in the inhibition of depolarization, blocking the transmission of nerve impulses. This agent is an option for longer postoperative analgesia. The onset will be delayed from 5 min to about 20 min.

Bupivacaine and epinephrine (Marcaine, Vivacaine, Sensorcaine)

Bupivacaine 0.25% with or without epinephrine may be used. It decreases permeability to sodium ions in neuronal membranes. This results in the inhibition of depolarization, blocking the transmission of nerve impulses.
