How Dopamine Agonist Drugs Work
Dopamine is a prominent part of our brain chemistry that influences our moods, motivation, and movement. When the dopaminergic pathways in the brain aren’t working effectively, physical and mental health issues may arise, impacting the quality of daily life. For some people, dopamine agonist drugs may provide a solution. Keep reading to learn more about how dopamine agonists can manage a variety of disorders and symptoms, including symptoms of Parkinson’s disease.
How do dopamine agonist drugs work?
To understand how dopamine agonists can help manage different disorders, it can be beneficial to first learn about what dopamine is and how it works. Dopamine is a chemical called a neurotransmitter. It acts as a messenger to help regulate motivation, reward, and movement. The message is sent and received if the dopaminergic pathways are functioning properly. When dopamine binds to its receptors, it triggers signaling in nerve cells.. Dopamine agonist drugs are chemical agents that activate a specific receptor to initiate a reaction in nerve cells in the dopaminergic pathway. For example, some of the older dopamine agonists interact with dopamine D1 and D2 receptors, serotonin, and adrenergic receptors, whereas newer dopamine agonists primarily attach to the dopamine D2 and D3 receptors.
Dopamine agonists mimic dopamine and affect the receptors. Dopamine antagonist are drugs or natural substances that block dopamine receptors to reduce symptoms associated with excess dopamine activity in the system. These symptoms can include hallucinations, delusions, hypersexuality, and impulse-control symptoms such as problematic gambling or binge eating. Antipsychotic medications, which are typically dopamine antagonists, are used frequently in the treatment of conditions such as bipolar disorder and schizophrenia. They can also be used to treat nausea and vomiting.
Dopamine agonist drugs effectively treat many disorders
Potential side effects of how dopamine agonist drugs work
Indirect dopamine receptor agonists include dopamine reuptake inhibitors and dopamine-releasing agents. They have been used in the treatment of Parkinson's disease and restless legs syndrome, and they may also have applications in other conditions in some cases. They may also be effective for some people experiencing depression.

While dopamine agonist medication can be extremely helpful for these conditions, they may also result in unwanted drug interactions or side effects such as:
- Euphoria
- Hallucinations
- Psychosis
- Low blood pressure upon standing
- Weight loss
- Loss of appetite
- Nausea and vomiting
- Insomnia
- Fatigue or weakness
- Dizziness
- Drowsiness
- Excessive daytime sleepiness
- Sudden sleep attacks
- Lightheadedness
- Irregular heartbeat
- Muscle twitching
- Involuntary movements
- Motor fluctuations
- Leg swelling
- Impulse-control symptoms related to gambling, shopping, or sexual behavior
- Withdrawal syndrome after long-term use
Drawbacks of taking dopamine agonists for treatment
Dopamine agonists work to increase dopamine like activity in the body by stimulating dopamine receptors. There are however a few drawbacks in addition to the listed side effects that may deter some individuals from using them.
For instance, the cost may play a determining role, although how much you will need to spend will depend on the specific medication you take, your dose, your insurance, and your location. Also, the drugs’ effectiveness relies on a commitment to treatment, whether you’re on higher or lower doses, and some patients report adverse side effects from stopping the medication.
For these reasons (among others), some patients choose to start with psychotherapy instead of medications as the sole treatment for dopamine-related symptoms, depending on severity and circumstances of their symptoms.
Natural dopamine agonists
Some foods and supplements may support dopamine production or dopamine-related activity in the body, although they do not necessarily work the same way as prescription dopamine agonist medications. Foods and supplements that may support dopamine levels include:
- Chicken
- Cheese
- Eggs
- Fish
- Watermelon
- Wheat germ
- Beans
- Ripe bananas
- Raw almonds
- Sunflower seeds
- Fruits and vegetables that contain antioxidants
- Theanine supplements or teas
- Tyrosine supplements
Dopamine dysfunction symptoms in Parkinson’s disease and others
Parkinson's disease, restless leg syndrome, narcolepsy, depression, and ADHD are examples of conditions associated with dopamine dysfunction. However, there are several factors beyond genetics or natural causes that may affect dopamine levels as well. For instance, poor diet, obesity, and stress have all been linked to changes in dopamine function.
Dopamine dysfunction symptoms
Dopamine dysfunction can cause a wide range of symptoms, including:
- Muscle cramps, stiffness, twitching, and body aches
- Balance problems
- Difficulty swallowing
- Slowed speech
- Lack of motivation
- Sleeping too much
- Restless legs syndrome
- Mood swings
- Depressed feeling
- Loss of pleasure in daily activities
- Forgetfulness
- Cravings for sweets, fats, and alcohol
- Trouble losing weight
- Low sex drive
Dopamine agonist drugs and psychotherapy
If you’re experiencing symptoms that may be related to dopamine dysfunction and you think that dopamine agonist treatment may be helpful, speak to your doctor or psychiatrist for guidance. Based on a full evaluation, they may discuss medication options, and depending on your symptoms, they may also recommend changes in diet.
Your doctor might also suggest that you attend adjunct therapy sessions in addition to, or instead of, taking dopamine agonist drugs. While more research is needed, studies suggest that psychotherapy can support changes in the brain that may help relieve some symptoms associated with dopamine-related conditions.

What are dopamine agonist drugs used for in treatment?
These medications activate certain types of cells in the brain, mirroring some of the effects of dopamine in the body. They are commonly used for movement disorders like Parkinson’s disease, as well as for restless legs syndrome, high prolactin levels, and some other medical conditions. Whether a dopamine agonist is appropriate depends on a full medical evaluation.
What is the best drug to increase dopamine?
The most appropriate medication depends on the condition being treated, a person’s health history, and a prescribing clinician’s evaluation. Examples of medications that affect dopamine pathways include:
- Amantadine
- Fenoldopam
- Apomorphine
- Pramipexole
- Rotigotine
What does an agonist do?
An agonist activates specific cells in the brain. Cells throughout the nervous system have what are called “receptors” which act as locks, while different neurotransmitters act as keys to these locks. Each key has a different shape, and unlocks specific functions. A dopamine receptor agonist works specifically on dopamine receptors with a similar mechanism of action to natural dopamine, so that the body reacts as though dopamine is present.
What are signs of low dopamine?
Dopamine has many functions in the body, to include helping regulate certain processes related to the heart, kidneys, reproductive system, endocrine system, and digestive system.
Signs of low dopamine, including Parkinson’s disease
Some common signs of low dopamine can include:
- A lack of motivation
- Difficulty concentrating
- Moodiness or anxiety
- Low sex drive
- Depressive symptoms, a feeling of hopelessness
- Sleep disturbances
- Hand tremors or cramps
- Parkinson’s disease
- Restless legs syndrome
- Symptoms associated with schizophrenia, including social withdrawal and reduced emotional expression
- Symptoms associated with ADHD, including impulsiveness, forgetfulness, and lack of organization
What foods support dopamine production?
Foods that are rich in magnesium and tyrosine can support dopamine production. This includes things like chicken, avocado, bananas, beets, chocolate, almonds, leafy greens, oatmeal, oranges, green tea, tomato, peas, and sesame seeds.
What happens when you have too much dopamine?
Too much dopamine in your system can lead to the following:
- Excessive energy
- Feelings of anxiety
- Hallucinations
- Mania
- Insomnia
- Impulse control issues
What happens if you take dopamine pills?
Dopamine agonist drugs activate dopamine receptors in the body in a similar way to the actual neurotransmitter. Dopamine receptor agonists can create effects in the body similar to increased dopamine activity, which may help address some effects associated with low dopamine.
Dopamine agonist therapy is commonly used to treat Parkinson’s disease and other movement disorders.
Which antidepressant increases dopamine?
Norepinephrine and dopamine reuptake inhibitors (NDRIs), including bupropion, may affect dopamine levels. Whether a medication is appropriate depends on an individual evaluation by a licensed medical provider.
How to make your brain release dopamine?
There are a number of ways to support dopamine activity in the brain without prescription drugs. Certain foods and supplements may influence dopamine-related pathways, including chocolate, probiotics, ginkgo, and green tea. There are also healthy lifestyle habits that are known for their potential to support dopamine levels, including regular exercise, getting sufficient sleep, and practicing mindfulness exercises like meditation.
What are the side effects of dopamine agonists?
Dopamine agonist therapy can be effective at treating many conditions and is generally considered safe when used under the supervision of a medical professional. There are some potential side effects linked with medication use, including depression, impulse control issues, mania, or confusion.
There can be drug interactions with MAOIs, and some people may need to stop taking them before starting dopamine agonist therapy, based on medical guidance. Pregnant people and those with high blood pressure or kidney or liver disease may need additional medical review before using a dopamine agonist.
Finally, around 15 to 20% of those who use dopamine agonists may experience what is known as dopamine agonist withdrawal syndrome (DAWS) when their dose is abruptly reduced or stopped altogether. Symptoms of dopamine agonist withdrawal syndrome may include:
- Agitation
- Excessive sweating
- Anxiety or panic attacks
- Pain
- Nausea
- Orthostatic hypotension
