Anesthetics are a class of strong analgesics that have strong analgesic properties without antipyretic and anti-inflammatory properties and are often used to numb specific areas of the body during medical procedures or surgery. This type of compound mainly acts on the central nervous system, including morphine and morphine-like drugs, esters such as procaine and benzocaine, and amides such as lidocaine and bupivacaine. Its function is to selectively inhibit pain sensation, which weakens the perception and reaction of pain and increases the pain threshold but does not affect other senses (touch, light, and hearing). In addition to their analgesic properties, these drugs are prone to addiction and should be strictly controlled.
