What is an articaine and epinephrine injection?

Articaine and epinephrine are used together as a dental anesthetic. They are injected, in various proportions, before dental surgery in order to diminish pain. Articaine is the primary anesthetic; it acts by increasing the threshold required for pain nerves to transmit an impulse. Epinephrine acts as a vasoconstrictor. This drug is available by prescription under a variety of different names, including Articadent and Septocaine.
