Procaine is a analgesic drug. It is used primarily to reduce the pain of getting certain shots, and is also used by dentists. The drug is usually sold under the name Novocaine, or Novacaine.

Procaine was first made in 1905, and was the first man-made pain-killer that could be taken as a shot. It was created by the German scientist Alfred Einhorn (1857-1917) who gave the chemical the name Novacaine, from the Latin word novus (which means new) and caine, as in "cocaine."
