Active ingredient

Chloroprocaine

Chloroprocaine is procaine in which one of the hydrogens ortho- to the carboxylic acid group is substituted by chlorine. Chloroprocaine, blocks the generation and the conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse and by reducing the rate of rise of the action potential. Chloroprocaine (like cocaine) has the advantage of constricting blood vessels which reduces bleeding, unlike other local anesthetics like lidocaine.
