Cocaine is a powerful stimulant known to make users feel energetic, cheerful, talkative, etc. In time, negative side effects include increased body temperature, irregular or rapid heart rate, high blood pressure, increased risk of heart attacks, strokes and even sudden death from cardiac arrest.
Cocaine addiction results from complex molecular changes in the brain following multiple exposures to cocaine. [16] Dynorphins have been shown to be an important part of this process. Although a single exposure to cocaine does not affect brain dynorphin levels, repeated exposures to the drug increases dynorphin concentrations in the striatum ...
The effects of KOR agonism on dopamine systems are well documented, and recent work also implicates the mitogen-activated protein kinase cascade and pCREB in KOR-dependent behaviors. [40] [81] While the predominant drugs of abuse examined have been cocaine (44%), ethanol (35%), and opioids (24%). [82]
Neuroscientists believe that drug addicts’ behavior is a direct correlation to some physiological change in their brain, caused by using drugs. This view believes there is a bodily function in the brain causing the addiction. This is brought on by a change in the brain caused by brain damage or adaptation from chronic drug use. [1] [2]
Behavioral neuropharmacology focuses on the study of how drugs affect human behavior (neuropsychopharmacology), including the study of how drug dependence and addiction affect the human brain. [2] Molecular neuropharmacology involves the study of neurons and their neurochemical interactions, with the overall goal of developing drugs that have ...
Cocaine is a non-selective, competitive inhibitor of monoamine transporters, sharing a similar mechanism with that of methylphenidate. Cocaine interacts with DAT, SERT, and NET, although the behavioral and reinforcing effects of cocaine depend on its inhibition of DAT and the increase in extracellular dopamine. [1]
Life gets more complicated when you have medical issues. High blood pressure adds extra caution to your day, the medications you use to treat health conditions come with side effects, and side ...
Drugs targeting the neurotransmitter of major systems affect the whole system, which can explain the complexity of action of some drugs. Cocaine , for example, blocks the re-uptake of dopamine back into the presynaptic neuron, leaving the neurotransmitter molecules in the synaptic gap for an extended period of time.
