Local Anesthetic Agents

Local anesthetic agents are medications used to temporarily block sensation in a specific area of the body. They work by inhibiting nerve signals, preventing pain during medical procedures such as dental work or minor surgeries. These agents are typically administered through injection or topical application, and they allow patients to remain awake and alert while experiencing minimal discomfort. The effects usually wear off within a few hours, and patients can return to their normal activities shortly afterward. Common examples include lidocaine and procaine.
