Novocain: Full Drug Profile
Novocain - General Information
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). [PubChem]
Pharmacology of Novocain
Novocain is an anesthetic agent indicated for production of local or regional anesthesia, particularly for oral surgery. Novocain (like cocaine) has the advantage of constricting blood vessels which reduces bleeding, unlike other local anesthetics like lidocaine. Novocain is an ester anesthetic. It is metabolized in the plasma by the enzyme pseudocholinesterase through hydrolysis into para-aminobenzoic acid (PABA), which is then excreted by the kidneys into the urine.
Novocain for patients
Novocain Interactions
Anticholinesterases
Concurrent use of procaine hydrochloride and anticholinesterase agents may result in increased systemic toxicity since anticholinesterases inhibit the breakdown of procaine hydrochloride.
Antimyasthenics
Concurrent use of procaine hydrochloride and antimyasthenics may result in loss of control of symptoms of myasthenia gravis due to antagonism of the effects of antimyasthenics on skeletal muscle. Temporary dosage adjustment of antimyasthenics may be required. Also antimyasthenics may have anticholinesterase activity.
CNS depressant medications
Concurrent use of procaine hydrochloride and CNS depressant medications may result in additive depressant effects.
Hyaluronidase
Hyaluronidase may increase the diffusion rate of procaine hydrochloride, resulting in a decreased time of onset, but an increase in systemic toxicity.
Neuromuscular blocking agents (such as suxamethonium chloride)
Concurrent use of procaine hydrochloride and neuromuscular blocking agents may result in prolongation or enhancement of the neuromuscular blockade.
Sulfonamides
Concurrent use of procaine hydrochloride and sulfonamides may result in a reduction of the antibacterial action of the sulfonamide.
Acetazolamide
Concurrent use of acetazolamide and procaine hydrochloride may extend the plasma half-life of procaine.

Additional information about Novocain
Novocain Indication: Used as a local anesthetic primarily in oral surgery Mechanism Of Action: Novocain acts mainly by inhibiting sodium influx through voltage gated sodium channels in the neuronal cell membrane of peripheral nerves. When the influx of sodium is interrupted, an action potential cannot arise and signal conduction is thus inhibited. The receptor site is thought to be located at the cytoplasmic (inner) portion of the sodium channel. Novocain has also been shown to bind or antagonize the function of N-methyl-D-aspartate (NMDA) receptors as well as nicotinic acetylcholine receptors and the serotonin receptor-ion channel complex.
