Description
Articaine HCl was introduced in the USA in 2000 and has become a very popular anesthetic agent. Though classified as an amide local anesthetic it is actually a hybrid molecule, possessing both ester and amide characteristics. With epinephrine, articaine provides approximately 60 minutes of pulpal anesthesia and between 3 to 5 hours of soft tissue anesthesia. Its unique molecular characteristics make articaine a preferred anesthetic in the pregnant and the nursing patient as well as the lighter weight (<30kg) pediatric patient. However, articaine is used as a 4% solution and there has been some concern about the possibility of 4% anesthetics possessing a greater risk of producing paresthesia than local anesthetics used in lesser concentrations.
