A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...

A local anesthetic is a drug that causes reversible local anesthesia and a loss of nociception.When it is used on specific nerve pathways (nerve block), effects such as analgesia (loss of pain sensation) and paralysis (loss of muscle power) can be achieved.
Chloroprocaine (trade name Nesacaine, Nesacaine-MPF) (often in the hydrochloride salt form as the aforementioned trade names) is a local anesthetic given by injection during surgical procedures and labor and delivery.

Articaine is a dental amide-type local anesthetic. It is the most widely used local anesthetic in a number of European countries [2] and is available in many countries. It is the only local anaesthetic to contain a thiophene ring, meaning it can be described as 'thiophenic'; this conveys lipid solubility. [3]
