Novocaine belongs to the group of local anesthetics. Novocaine prevents generation of impulses in sensorial nerves endings and along nerve fibers; inhibits both painful and other impulses; intravenous administrated, affects generally the animal body; reduces acetylcholine formation and decreases affectability of peripheral cholinergic systems; provides a blocking effect on autonomic ganglion; reduces smooth muscles spasms; reduces irritability of heart muscle and the brain motor areas; causes excitation in toxic doses, followed by central nervous system paralysis.
Fast hydrolyzed, forming PABA and diethylaminoethanol, being pharmacologically active substances.
Fast and acute, when administrated.
Infiltration anesthesia in the form of 0,125%‑0,5% solution, previously diluted with sterile saline to the desired concentration.
