Cocaine Action Pathway

Homo sapiens
Cocaine exerts its local anaesthetic effect by blocking voltage-gated sodium channels in peripheral neurons. Cocaine diffuses across the neuronal plasma membrane in its uncharged base form. Once inside the cytoplasm, it is protonated and this protonated form enters and blocks the pore of the voltage-gated sodium channel from the cytoplasmic side. For this to happen, the sodium channel must first become active so that so that gating mechanism is in the open state. Therefore cocaine preferentially inhibits neurons that are actively firing.

Cocaine Analgesic Action Pathway

Homo sapiens
Cocaine is a local anesthesia and vasoconstrictor that is clinically used during diagnostic proceedures or during surgery in or through the nasal cavity. It comes in drugs called Goprelto and Numbrino which comes as a nasal spray. In these clinical drugs it takes the form of cocaine hydrochloride. The illicit drug has the same effects. Primarily it acts on sensory neurons in the nasal cavity by inhibiting the sodium channels. Stimulation from touch, pressure, stretch, or pain causes sodium channels on sensory receptors to open. Cocaine inhibits those channels, preventing the sensory receptor from depolarizing and triggering an action potential. The different types of sensory neurons it inhibits are mechanoreceptors(pressure, vibrations, and texture), thermoreceptors (temperature), and nociceptors (pain). The prevention of depolarization and action potential in these neurons causes an anesthetic effect in the nasal cavity.

Cocaine Dopamine-reuptake Inhibitor Action Pathway

Homo sapiens
Cocaine is a local anesthesia and vasoconstrictor that is clinically used during diagnostic proceedures or during surgery in or through the nasal cavity. It comes in drugs called Goprelto and Numbrino which comes as a nasal spray. In these clinical drugs it takes the form of cocaine hydrochloride. The illicit drug has the same effects. It primarily acts on sensory neurons in the nasal cavity, but also inhibits dopamine, serotonin, and norepinephrine re-uptake channels. This inibition leads to an accumulation in the synapse of these neurotransmitters. For dopamine this leads to activation of dopamine receptors, especially the D2 dopamine receptor which has been implicated in the cause of addiction through the reward pathway. D2 receptors inhibit adenylate cyclase which leads to a lower concentration of cAMP which lowers neuronal excitability. Other dopamine receptors also have an effect on addiction,, especially the D1 dopamine receptor. The exact mechanisms in which D2 receptors cause addiction is unknown. D1 dopamine receptors also have an effect on addiction. They are Gs coupled and activated adenylate cyclase rather than inhibit. D1-D2 dopamine receptor heteromers have also been found to effect addiction, although they have not been researched enough to understand how.
