Description:
Procaine is a local anesthetic drug of the amino ester group. It is used primarily to reduce the pain of intramuscular injection of penicillin, and it is also used in dentistry. Owing to the ubiquity of the trade name Novocain, in some regions procaine is referred to generically . It acts mainly by being a sodium channel blocker. Today it is used therapeutically in some countries due to its sympatholytic, anti-inflammatory, perfusion enhancing, and mood enhancing effects.
Procaine was first synthesized in 1905, shortly after amylocaine. It was created by the German chemist Alfred Einhorn who gave the chemical the trade name , from the Latin nov- (meaning new) and -caine, a common ending for alkaloids used as anesthetics. It was introduced into medical use by surgeon Heinrich Braun. Prior to the discovery of Stovaine and was the most commonly used local anesthetic Einhorn wished his new discovery to be used for amputations, but surgeons preferred general anesthetic. Dentists, however, found it very useful. Einhorn was displeased by this and spent many years touring dental schools to advise them not to use it.

Application:
Procaine is the primary ingredient in the controversial preparation Gerovital H3 by Ana Aslan (Romania), which is claimed by its advocates to remedy many effects of aging. The mainstream medical view is that these claims were seriously studied and discredited in the 1960s.
A 1% procaine injection has been recommended for the treatment of extravasation complications associated with venipuncture (along with moist heat, ASA, steroids, antibiotics). It has likewise been recommended for treatment of inadvertent intra-arterial injections (10 ml of 1% procaine), as it helps relieve pain and vascular spasm.
Procaine is an occasional additive in illicit street drugs.
