Source & Nature
PROCAINUM is the homeopathic name for procaine, a synthetic aminoester local anaesthetic of the para-aminobenzoic acid (PABA) series. The free base is C13H20N2O2 (CAS 59-46-1, PubChem CID 4914); the usual pharmaceutical salt is procaine hydrochloride, C13H21ClN2O2 (CAS 51-05-8, PubChem CID 5795). It was first synthesised in 1905 by the German chemist Alfred Einhorn as a safer alternative to cocaine and introduced into surgery by Heinrich Braun under the trade name Novocain.
Commercially it has been used as an injectable local and regional anaesthetic in dentistry, infiltration and neuraxial blocks, and as a depot carrier for intramuscular penicillin (penicillin G procaine). It should be distinguished from procainamide, a related amide antiarrhythmic.
