Dopaminesold under the brandname Intropin among others, is a medication most commonly used in the treatment of very low blood pressurea slow heart rate that is causing symptoms, and, if epinephrine is not available, cardiac arrest. Common side effects include worsening kidney functionan irregular heartbeatchest painvomitingheadacheor anxiety. In newborn babies it continues to be the preferred treatment for very low blood pressure.
In those with low blood volumethis should be corrected with intravenous fluids before dopamine is considered. Low-dosage dopamine has been routinely used for the treatment and prevention of acute kidney injury. However, since a number of reviews have concluded that doses at such low levels are not effective and may sometimes be harmful. Since the half-life of dopamine in plasma is short—approximately one minute in adults, two minutes in newborn babies and up to five minutes in preterm babies —it is usually given as a continuous intravenous drip rather than a single injection.
A fluorinated form of L-DOPA known as fluorodopa is available for use in positron emission tomography to assess the function of the nigrostriatal pathway. Dopamine should generally not be given to people who have a pheochromocytoma or uncorrected very fast heart rate. If extravasation occurs local tissue death may result. Its effects, depending on dosage, include an increase in sodium excretion by the kidneys, an increase in urine output, an increase in heart rateand an increase in blood pressure.

What Is Dopamine?Why do people continue to use alcohol and other drugs chronically even after experiencing serious medical, social, legal, or financial consequences? This is a question that has interested professionals in a wide variety of addiction-related fields for many years.
Advances in neuroscience and biology have allowed scientists to better understand the physical roots of substance use and dependence, which has led to the contemporary disease model of addiction. By studying and understanding the biological characteristics of substance dependence, scientists and physicians are able to develop medical and pharmacological treatments that can significantly improve recovery outcomes.
In order to carry out all of its necessary functions, from making sure your lungs are breathing to working out a calculus algorithm, the brain uses a complex communication system made up of tree-like cells called neurons. Neurons send electrical signals through your brain and the rest of your nervous system in order to manage everything that happens in the body. These electrical signals are controlled by chemicals called neurotransmitters, which are secreted from within the neurons and sent out in the brain to other surrounding neurons in order to activate or deactivate them.
Neurons absorb these neurotransmitters through receptors. Each neurotransmitter is like a key, and it fits into its own specific receptor, which acts like a lock. In order to maintain balance, the brain is able to change these receptor "locks" to fit other neurotransmitters when there is too much, or not enough, of a certain neurotransmitter in the system. While there are many different kinds of neurotransmitters, each neuron is only designed to produce one or two specific types.
Generally, neurons are grouped together based on the neurotransmitters they produce and receive, which is why specific areas of the brain regulate certain functions. The early draw of drug use for most people is the pleasurable feeling they get while "high," 2 a feeling that results from electric stimulation of specific areas of the brain that make up what is collectively called the brain's "reward center": the ventral tegmental area VTAnucleus accumbens NAcand substantia nigra SNall of which are located near the front of the brain.
Alcohol and other mood-altering drugs, however, artificially create this effect and do so more efficiently and intensely than natural rewards. While the intense feelings of pleasure and reward derived from early drug use can play a substantial part in continued use of the drug, it is only a small part of the neurophysiological cycle of addiction.
Learning has long been understood to be tied to the administration of rewards and punishments, and the intense reward sensation of drug intoxication creates a strong and rapid learning response in the brain, associating drug use with feelings of pleasure.
First, reduced dopamine receptors in the SN are associated with impulsive behavior that has been tied in lab studies to escalating and compulsive self-administration of drugs. The depressive feelings of anhedonia can drive a user to administer drugs in a reactive attempt to feel pleasure again, especially in a state of low self-control. Increased understanding of the function and mechanisms of the brain's reward system, particularly dopamine and its receptors, has led to several innovations related to medical treatment of addiction and cravings.
Some clinicians now use dopamine agonists and antagonists. These substances act like "skeleton keys" by fitting into the receptors meant for dopamine and either initiating the same response that the dopamine would have agonist or shutting down the response that dopamine would have initiated antagonist. Treatment at each of the Hazelden Betty Ford Foundation sites is constantly guided and improved by scientific innovation. As a result, our treatment plans incorporate pharmacological treatments with traditional counseling sessions for patients with high-risk dependence behaviors.
Do the brain's dopamine levels and reward center ever return to normal after drug use stops? Recently, scientists have discovered that after long periods of abstinence from alcohol and other drugs, the brain's physiology does begin to return to normal.
By maintaining lower dopamine levels in the brain, dopamine receptors can start returning to higher, normal levels. Increasing the number of dopamine receptors to normal levels reduces impulsivity and anhedonia symptoms. Additionally, abstinence from drugs and alcohol for a year or longer has been shown to allow the brain to begin repairing structural damage caused by drug toxicity, which in turn improves cognitive function and allows chemically dependent patients to exert stronger self-control.
For Family Members: While the consequences of longterm substance abuse alone may seem dire enough to convince your loved one to stop using, it is important to remember that the chemically dependent person's reasoning and decision-making are impaired by the physical effects of drug use.
If you know someone who is unable to stop using despite clear negative consequences, it is important to encourage him or her to seek medical help because substance abusers may benefit from taking prescription medication to control the physiological symptoms of their dependence.
The Hazelden Betty Ford Foundation is a force of healing and hope for individuals, families and communities affected by addiction to alcohol and other drugs. As the nation's leading nonprofit provider of comprehensive inpatient and outpatient treatment for adults and youth, the Foundation has 17 locations nationwide and collaborates with an expansive network throughout health care.
With a legacy that began in and includes the founding of the Betty Ford Center, the Foundation today also encompasses a graduate school of addiction studies, a publishing division, an addiction research center, recovery advocacy and thought leadership, professional and medical education programs, school-based prevention resources and a specialized program for children who grow up in families with addiction.

All Rights Reserved.Dopamine is a neurotransmitter that helps us feel pleasure and stay motivated. Though oral dosing of dopamine is ineffective—it cannot cross the blood-brain barrier—dopamine building blocks can enter the central nervous system and be converted into dopamine in the brain.
In addition, certain pharmaceutical medicines can create a functional increase in dopamine—though this strategy may deplete this important neurotransmitter over the long term. Levodopa is a compound that the human body is able to convert into dopamine. This process does not just happen in the brain, however. If levodopa is taken by itself, much of it is converted to dopamine outside of the central nervous system, which blunts its therapeutic effect.
This dopamine is not able to cross the blood-brain barrier and tends to cause side effects like nausea and vomiting. Some levodopa will cross into the brain and be converted to dopamine, but the amount is unpredictable. Therefore, levodopa is combined with carbidopa—a compound that prevents conversion to dopamine in the periphery. Mucuna pruriens is an herb that happens to contain levodopa in its seeds. In Ayurvedic medicine, it is a traditional treatment for depression.
Ingesting a powder of crushed Mucuna seeds does not seem to result in the conversion problems encountered with a pharmaceutical preparation of levodopa. However, this was only one study, and more research is needed. Tyrosine is an amino acid that is the foundational building block of dopamine.
L-tyrosine is converted into levodopa which is, in turn, converted into dopamine. When tyrosine is taken at levels that are greater than what is possible from diet alone, central nervous system amounts of dopamine increase. This strategy gives each dopamine molecule a longer lifespan and increases dopamine-derived nerve transmission.

About the Author.Dopamine DAa contraction of 3,4- d ihydr o xy p henethyl amine is an organic chemical of the catecholamine and phenethylamine families. It functions both as a hormone and a neurotransmitterand plays several important roles in the brain and body. It is an amine synthesized by removing a carboxyl group from a molecule of its precursor chemical L-DOPAwhich is synthesized in the brain and kidneys.
Dopamine is also synthesized in plants and most animals. In the brain, dopamine functions as a neurotransmitter —a chemical released by neurons nerve cells to send signals to other nerve cells. The brain includes several distinct dopamine pathwaysone of which plays a major role in the motivational component of reward-motivated behavior.
The anticipation of most types of rewards increases the level of dopamine in the brain,  [ failed verification ] and many addictive drugs increase dopamine release or block its reuptake into neurons following release.
Other brain dopamine pathways are involved in motor control and in controlling the release of various hormones. These pathways and cell groups form a dopamine system which is neuromodulatory.
In popular culture and media, dopamine is usually seen as the main chemical of pleasure, but the current opinion in pharmacology is that dopamine instead confers motivational salience ;    in other words, dopamine signals the perceived motivational prominence i.
Outside the central nervous system, dopamine functions primarily as a local paracrine messenger. In blood vessels, it inhibits norepinephrine release and acts as a vasodilator at normal concentrations ; in the kidneys, it increases sodium excretion and urine output; in the pancreas, it reduces insulin production; in the digestive system, it reduces gastrointestinal motility and protects intestinal mucosa ; and in the immune system, it reduces the activity of lymphocytes.
With the exception of the blood vessels, dopamine in each of these peripheral systems is synthesized locally and exerts its effects near the cells that release it. Several important diseases of the nervous system are associated with dysfunctions of the dopamine system, and some of the key medications used to treat them work by altering the effects of dopamine.
Parkinson's diseasea degenerative condition causing tremor and motor impairment, is caused by a loss of dopamine-secreting neurons in an area of the midbrain called the substantia nigra. There is evidence that schizophrenia involves altered levels of dopamine activity, and most antipsychotic drugs used to treat this are dopamine antagonists which reduce dopamine activity.
Restless legs syndrome and attention deficit hyperactivity disorder ADHD are associated with decreased dopamine activity. Dopamine itself is available as a manufactured medication for intravenous injection : although it cannot reach the brain from the bloodstreamits peripheral effects make it useful in the treatment of heart failure or shockespecially in newborn babies.
A dopamine molecule consists of a catechol structure a benzene ring with two hydroxyl side groups with one amine group attached via an ethyl chain.Dopamine Nursing Considerations, Side Effects, and Mechanism of Action Pharmacology for Nurses
Like most amines, dopamine is an organic base. Dopamine is synthesized in a restricted set of cell types, mainly neurons and cells in the medulla of the adrenal glands.
