4 Pharmacology and Biochemistry
4.1 MeSH Pharmacological Classification

Anesthetics

Agents capable of inducing a total or partial loss of sensation, especially tactile sensation and pain. They may act to induce general ANESTHESIA, in which an unconscious state is achieved, or may act locally to induce numbness or lack of sensation at a targeted site. (See all compounds classified as Anesthetics.)
