Anesthetic

Capable of producing anesthesia.

Substance that decreases the capacity of nerves to experience pain.

A substance that blocks sensation and dulls pain.

Numbs perception of external sensations.

That which produces loss of sensation with or without loss of consciousness.

A substance that decreases nerve sensitivity to pain. (Examples: nitrous oxide, Peppermint.)

Abolishes sensitivity to external stimuli.

A drug used to induce sleep and to reduce sensitivity to pain.

An agent that deadens sensation.

Drugs that cause a loss of sensation, including pain. Anesthetics may be general, which is when a temporary loss of consciousness is induced in a patient, or local, when specific nerves are targeted to produce numbness (and a loss of sensation) in only that part of the body.

An agent that reduces or abolishes sensation, affecting either the whole body (general anesthetic) or a particular region (local anesthetic). General anesthetics, used for surgical procedures, depress activity of the central nervous system, producing loss of consciousness. ‘Anesthesia is induced by short-acting barbiturates (such as thiopental) and maintained by inhalation anesthetics (such as halothane). Local anesthetics inhibit conduction of impulses in sensory nerves in the region where they are injected or applied; they include cocaine and lignocaine.

A drug or other agent which depresses feeling or the sensation of pain.

A drug or substance that causes loss of feeling or awareness. Local anesthetics cause loss of feeling in a part of the body. General anesthetics put the person to sleep.

This substance acts as a suppressor of neuronal activity, ultimately leading to a diminishment of the capacity to sense physical discomfort and other forms of stimuli.

Anesthetics are medications that induce a state of insensitivity, particularly towards pain. Certain types of anesthetics can also induce a loss of consciousness.
