Dopamine is a neurotransmitter that regulates movement, emotional response and the ability to feel pleasure and pain. When dopamine is secreted from the presynaptic neuron, it moves into the frontal lobe and regulates the flow of information from other parts the brain. An excess amount of dopamine is associated with paranoia and schizophrenia while decreased levels of dopamine are associated with depression and loss of memory. Drugs such as Wellbutrin, Mirapex and Cabergoline are proven to increase the level of dopamine in the brain.
Wellbutrin
Wellbutrin is an antidepressant medication classified as a dopamine reuptake inhibitor, notes Anxiety-and-depression-solutions.com. Wellbutrin prevents the reuptake of dopamine into the presynaptic synapse and thus increases the level of dopamine in the central nervous system.
Mirapex
Mirapex is dopamine receptor agonist used to stimulate dopamine receptor sites in the brain and consequently increase the level of dopamine. Mirapex is a medication prescribed for treatment of Parkinson's disease. Parkinson's disease is caused by a shortage of dopamine, which leads to uncontrolled movements, tremors and spasms. Mirapex increases the level of dopamine in the brain and thus relieves the symptoms of Parkinson's disease. While the exact mechanism by which Mirapex increases dopamine levels and relieves the symptoms of Parkinson's disease is unknown, scientists believe it is related to Mirapex’s ability to stimulate dopamine D2 and D3 receptors in the striatum, notes drugdevelopment-technology.com.
Cabergoline
Cabergoline is a dopamine agonist used for the treatment of Parkinson's disease. Cabergoline increases the level of dopamine by stimulating D2 receptor sites and thus relieves the uncontrolled movements associated with Parkinson's disease.
