Local anaesthetics are a sub-classification of anaesthetics. They generally induce insensitivity to pain and are therefore used to induce anaesthesia.Local anaesthetic drugs achieve this by causing a temporary loss of sensation. Therefore they numb feelings in a specific part of the body. Furthermore, they usually last for only a short time. These drugs are useful for minor surgeries and procedures that can be done quickly.
Only qualified medical professionals should administer these medications.
