anesthetics
Pain-blocking medications
Anesthetics are drugs that cause loss of sensation, used to prevent pain during medical procedures.
Local anesthetics numb a specific area: The dentist injected anesthetic before the extraction.
General anesthetics render patients unconscious for surgery.
The term extends figuratively to anything that dulls awareness or feeling: Television as anesthetic for the masses.
