Treatment Options for Cocaine Abuse and Amphetamines Background
- Methylphenidate has a greater effect in control subjects, while the DA system in dependent individuals is less responsive to DA reuptake blocking, contributing to behavioral tolerance and a "hypodopaminergic" state.
- Chronic cocaine use has systemic effects on organ systems, and high-dose use can lead to panic attacks, temporary paranoid psychosis, and elevated body temperature, which can cause multiple organ failure and overdose death.
- There are no FDA-approved medications for treating cocaine abuse, but some studies show a significant decrease in cocaine use with ketamine, a diabetes drug, and gene therapy, and GLP-1 agonists have shown potential in reducing the intake of palatable food.
- Clinical trials using older GLP-1 analogs have been completed, and new trials using semaglutide are underway to determine its capabilities against addiction and to identify which patients are most likely to benefit.
- GLP-1 is produced by neurons in the NTS and sends direct projections to the VTA and nucleus accumbens, regulating the intake of highly palatable food.
- Previous work has shown that GLP-1 agonist drugs reduce the intake of palatable food, and GLP-1 is produced by neurons in the NTS, which sends projections to structures in the mesolimbic DA circuit.

- Amphetamine and methamphetamine, also known as "uppers," "bennies," "dexies," "black beauties," "diet pills," "meth," "speed," "crank," and "zip," have long half-lives and are metabolized by the liver at a slow rate.
- Amphetamine and methamphetamine are indirect agonists of the catecholaminergic systems and can enter DA nerve terminals via uptake by DAT and cause vesicles to release DA into the cytoplasm.
- Chronic cocaine use has systemic effects on organ systems, and high-dose use can lead to panic attacks, temporary paranoid psychosis, and elevated body temperature, which can cause multiple organ failure and overdose death.
- There are no FDA-approved medications for treating cocaine abuse, but some studies show a significant decrease in cocaine use with ketamine, a diabetes drug, and gene therapy, and GLP-1 agonists have shown potential in reducing the intake of palatable food.
Acute Behavioral and Physiological Effects of Cocaine
- Cocaine has powerful reinforcing properties and high abuse potential, often with no alternative reinforcer available in self-administration studies.
- Animals trained to press a lever for either saccharin or IV cocaine showed a preference for saccharin, despite cocaine having a higher breaking point.
- The addictive potential of intense sweetness may result from an inborn hypersensitivity to sweet tastants due to the evolution of sweet receptors in mammals.
- Cocaine, a psychomotor stimulant, activates the sympathetic nervous system, leading to increased heart rate, vasoconstriction, hypertension, and hyperthermia.
- Thalamic hemorrhage and changes in blood vessels are observed after cocaine use, signifying reduced blood flow.
- Rats genetically divided into low and high cocaine responder groups showed differences in dopamine signaling and locomotor behavior.
- In humans, the intensity of the "high" from cocaine depends on dopamine transporter (DAT) occupancy, rate of occupancy, baseline DA release, and individual differences.
- A genomic analysis revealed that individuals with increased levels of DAT due to a polymorphism in the DAT gene had a greater behavioral response to cocaine challenge.
- Chronic cocaine exposure leads to adaptations in the nucleus accumbens (NAcc) underlying tolerance and sensitization, resulting in reduced dopamine release and clearance.
- Transition from recreational to compulsive cocaine use is modeled, showing escalating intake and increased reward response in long-access sessions.
- Factors contributing to chronic cocaine abuse include tolerance to euphoric effects, comorbidity with psychiatric disorders, incubation of craving, and abnormal prefrontal cortex function.
- PET imaging of cocaine-dependent individuals showed reduced baseline D2 receptor binding, indicating neurochemical changes in the brain due to chronic cocaine use.

- Methylphenidate has a greater effect in control subjects, while the DA system in dependent individuals is less responsive to DA reuptake blocking, contributing to behavioral tolerance and a "hypodopaminergic" state.
- Chronic cocaine use has systemic effects on organ systems, and high-dose use can lead to panic attacks, temporary paranoid psychosis, and elevated body temperature, which can cause multiple organ failure and overdose death.
- There are no FDA-approved medications for treating cocaine abuse, but some studies show a significant decrease in cocaine use with ketamine, a diabetes drug, and gene therapy, and GLP-1 agonists have shown potential in reducing the intake of palatable food.
- Clinical trials using older GLP-1 analogs have been completed, and new trials using semaglutide are underway to determine its capabilities against addiction and to identify which patients are most likely to benefit.
- GLP-1 is produced by neurons in the NTS and sends direct projections to the VTA and nucleus accumbens, regulating the intake of highly palatable food.
- Previous work has shown that GLP-1 agonist drugs reduce the intake of palatable food, and GLP-1 is produced by neurons in the NTS, which sends projections to structures in the mesolimbic DA circuit.
- Amphetamines, including amphetamine and methamphetamine, are synthetic derivatives of phenylethylamine and natural amphetamines include cathinone, ephedrine, and pseudoephedrine.
- Alexander Shulgin, also known as Dr. Ecstasy, wrote "Phenethylamines I Have Known And Loved" and contributed to the understanding of amphetamines.
- Amphetamine and methamphetamine, also known as "uppers," "bennies," "dexies," "black beauties," "diet pills," "meth," "speed," "crank," and "zip," have long half-lives and are metabolized by the liver at a slow rate.
- Amphetamine and methamphetamine are indirect agonists of the catecholaminergic systems and can enter DA nerve terminals via uptake by DAT and cause vesicles to release DA into the cytoplasm.
- Chronic cocaine use has systemic effects on organ systems, and high-dose use can lead to panic attacks, temporary paranoid psychosis, and elevated body temperature, which can cause multiple organ failure and overdose death.
- There are no FDA-approved medications for treating cocaine abuse, but some studies show a significant decrease in cocaine use with ketamine, a diabetes drug, and gene therapy, and GLP-1 agonists have shown potential in reducing the intake of palatable food.
