Cocaine is an ester local anesthetic used during diagnostic procedures and surgeries in or through the nasal cavities.
Cocaine produces anesthesia by inhibiting excitation of nerve endings or by blocking conduction in peripheral nerves. This is achieved by reversibly binding to and inactivating sodium channels. Sodium influx through these channels is necessary for the depolarization of nerve cell membranes and subsequent propagation of impulses along the course of the nerve. Cocaine is the only local anesthetic with vasoconstrictive properties. This is a result of its blockade of norepinephrine reuptake in the autonomic nervous system. Cocaine binds differentially to the dopamine, serotonin, and norepinephrine transport proteins and directly prevents the re-uptake of dopamine, serotonin, and norepinephrine into pre-synaptic neurons. Its effect on dopamine levels is most responsible for the addictive property of cocaine.
