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]
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]
Procaine is a local anesthetic drug of the amino ester group. It is most commonly used in dental procedures to numb the area around a tooth [1] and is also used to reduce the pain of intramuscular injection of penicillin. Owing to the ubiquity of the trade name Novocain or Novocaine, in some regions, procaine is referred to generically as ...
Amide-linked local anesthetic agents, such as lidocaine and bupivacaine, can become "trapped" in their ionized forms on the fetal side of the placenta, so their net transfer across the placenta is increased. An ester-linked local anesthetic agent, such as 2-chloroprocaine, is rapidly metabolized, and placental transfer is limited.
MEGX has a longer half-life than lidocaine, but also is a less potent sodium channel blocker. [49] The volume of distribution is 1.1 L/kg to 2.1 L/kg, but congestive heart failure can decrease it. About 60% to 80% circulates bound to the protein alpha 1 acid glycoprotein .
Prilocaine (/ ˈ p r aɪ l ə ˌ k eɪ n / [1]) is a local anesthetic of the amino amide type first prepared by Claes Tegner and Nils Löfgren.In its injectable form (trade name Citanest), it is often used in dentistry.

Skin paleness – usually disappear in few minutes to half an hour. [6] Tissue necrosis – usually seen in the hard palate.
