Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). 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 ...
Drug-induced amnesia is amnesia caused by drugs. Amnesia may be therapeutic for medical treatment or for medical procedures, or it may be a side-effect of a drug, such as alcohol, or certain medications for psychiatric disorders, such as benzodiazepines. [1] It is seen also with slow acting parenteral general anaesthetics. [citation needed]
Local anesthesia, in a strict sense, is anesthesia of a small part of the body such as a tooth or an area of skin. Regional anesthesia is aimed at anesthetizing a larger part of the body such as a leg or arm. Conduction anesthesia encompasses a great variety of local and regional anesthetic techniques.
Local anesthetic injections are given in specific areas of the mouth, rather than the whole body. Although several different medications are available, the most commonly used local anesthetic to prevent pain in the area around a tooth is lidocaine (also called xylocaine or lignocaine). Lidocaine's half-life in the body is about 1.5–2 hours. [2]
Examples of preanesthetic agents are: Acepromazine [1]; atropine [1]; diazepam [1]; Scopolamine; Opioid analgesics, such as morphine, pethidine and buprenorphine.; These drugs are used before the administration of an anesthetic to improve patient comfort, reduce possible side effects such as Postanesthetic shivering, relieve pain, and increase the effectiveness of the anesthetic.
In the United States, cocaine is regulated as a Schedule II drug under the Controlled Substances Act, meaning that it has a high potential for abuse but has an accepted medical use. [38] While rarely used medically today, its accepted uses are as a topical local anesthetic for the upper respiratory tract as well as to reduce bleeding in the ...
Benzocaine, sold under the brand name Orajel amongst others, is a local anesthetic, belonging to the amino ester drug class, commonly used as a topical painkiller or in cough drops. It is the active ingredient in many over-the-counter anesthetic ointments such as products for oral ulcers. It is combined with antipyrine to form A/B ear drops.
