Lidocaine's half-life in the body is about 1.5–2 hours. [2] The time it takes for the anesthetic medication to prevent pain in the area (speed of onset) and length of time that the area does not have painful sensations are considerations when choosing an appropriate approach to dental treatment.
Lidocaine/prilocaine is a eutectic mixture of equal quantities (by weight) of lidocaine and prilocaine. A 5% emulsion preparation, containing 2.5% each of lidocaine/prilocaine, is marketed by APP Pharmaceuticals under the trade name EMLA (an abbreviation for Eutectic Mixture of Local Anesthetics ).

Lidocaine is an antiarrhythmic medication of the class Ib type. [7] This means it works by blocking sodium channels thus decreasing the rate of contractions of the heart. [10] [7] When injected near nerves, the nerves cannot conduct signals to or from the brain. [8] Lidocaine was discovered in 1946 and went on sale in 1948. [11]
The GI cocktail is a mixture of a viscous anesthetic, an antacid, and an anticholinergic. [1] [2] Common viscous anesthetics use are viscous lidocaine or xylocaine.Common antacids used are magnesium hydroxide, aluminum hydroxide, or simethicone (more commonly known as Mylanta or Maalox). [3]
Aside from its use as a dental anesthetic, procaine is used less frequently today, since more effective (and hypoallergenic) alternatives such as lidocaine (Xylocaine) exist. Like other local anesthetics (such as mepivacaine , and prilocaine ), procaine is a vasodilator, thus is often coadministered with epinephrine for the purpose of ...
Studies comparing lidocaine and articaine found that articaine is more effective than lidocaine in anaesthetising the posterior first molar region. [12] Articaine has been found to be 3.81 times more likely than lidocaine to produce successful anaesthesia when used for infiltration injections.
To induce general anesthesia, propofol is the drug used almost exclusively, having largely replaced sodium thiopental. [13]It is often administered as part of an anesthesia maintenance technique called total intravenous anesthesia, using either manually programmed infusion pumps or computer-controlled infusion pumps in a process called target controlled infusion (TCI).
Pethidine is indicated for the treatment of moderate to severe pain, and is delivered as a hydrochloride salt in tablets, as a syrup, or by intramuscular, subcutaneous, or intravenous injection. For much of the 20th century, pethidine was the opioid of choice for many physicians; in 1975, 60% of doctors prescribed it for acute pain and 22% for ...
