Procaine is a benzoic acid derivative with local anesthetic and antiarrhythmic properties. Procaine binds to and inhibits voltage-gated sodium channels, thereby inhibiting the ionic flux required for the initiation and conduction of impulses. In addition, this agent increases electrical excitation threshold, reduces rate of rise of action potential and slows nerve impulse propagation thereby causing loss of sensation.

NCI Thesaurus (NCIt)

Procaine is a benzoate ester, formally the result of esterification of 4-aminobenzoic acid with 2-diethylaminoethanol but formed experimentally by reaction of ethyl 4-aminobenzoate with 2-diethylaminoethanol. It has a role as a local anaesthetic, a central nervous system depressant, a peripheral nervous system drug and a drug allergen. It is a benzoate ester, a substituted aniline and a tertiary amino compound. It derives from a 2-diethylaminoethanol and a 4-aminobenzoic acid. It is a conjugate base of a procaine(1+).


A local anesthetic of the ester type that has a slow onset and a short duration of action. It is mainly used for infiltration anesthesia, peripheral nerve block, and spinal block. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1016). Procaine has also been investigated as an oral entry inhibitor in treatment-experienced HIV patients.
