Dopamine Agonist Withdrawal Syndrome
If you suddenly stop taking dopamine agonists, this can lead to dopamine agonist withdrawal syndrome, which can cause symptoms such as depression, anxiety or pain.
Any withdrawal from Parkinsons drugs needs to be done in a tapered way, under the supervision of a health professional.
Speak to your specialist for advice.
What Should I Know About Storage And Disposal Of This Medication
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture .
Store cassettes containing levodopa and carbidopa enteral suspension in the refrigerator in their original carton, protected from light. Do not freeze the suspension.
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location â one that is up and away and out of their sight and reach.
Managing Medication Interactions And Side Effects
All prescribed medications can have potential side effects, including those used to treat Parkinsons. Some things you think are symptoms of Parkinsons may actually be side effects of medication. Some peoples side effects will have a big impact on their lives and have to be kept under control along with the symptoms.

Why Is This Medication Prescribed
The combination of levodopa and carbidopa is used to treat the symptoms of Parkinson’s disease and Parkinson’s-like symptoms that may develop after encephalitis or injury to the nervous system caused by carbon monoxide poisoning or manganese poisoning. Parkinson’s symptoms, including tremors , stiffness, and slowness of movement, are caused by a lack of dopamine, a natural substance usually found in the brain. Levodopa is in a class of medications called central nervous system agents. It works by being converted to dopamine in the brain. Carbidopa is in a class of medications called decarboxylase inhibitors. It works by preventing levodopa from being broken down before it reaches the brain. This allows for a lower dose of levodopa, which causes less nausea and vomiting.
How Anticholinergics Are Used
These medications are older and are not used very often for Parkinsons today. Sometimes they are prescribed for reducing tremor and muscle stiffness. They can be used on their own, especially in the early stages of your Parkinsons when symptoms are mild, before levodopa is prescribed.
Anticholinergics can also be used with levodopa or a glutamate antagonist. They are taken as tablets or as a liquid.

What Are The Surgical Treatments For Parkinsons Disease
Most patients with Parkinsons disease can maintain a good quality of life with medications. However, as the disease worsens, medications may no longer be effective in some patients. In these patients, the effectiveness of medications becomes unpredictable reducing symptoms during on periods and no longer controlling symptoms during off periods, which usually occur when the medication is wearing off and just before the next dose is to be taken. Sometimes these variations can be managed with changes in medications. However, sometimes they cant. Based on the type and severity of your symptoms, the failure of adjustments in your medications, the decline in your quality of life and your overall health, your doctor may discuss some of the available surgical options.
What Causes Parkinsons Disease
Parkinsons disease occurs when nerve cells in an area of the brain called the substantia nigra become impaired or die. These cells normally produce dopamine, a chemical that helps the cells of the brain communicate . When these nerve cells become impaired or die, they produce less dopamine. Dopamine is especially important for the operation of another area of the brain called the basal ganglia. This area of the brain is responsible for organizing the brains commands for body movement. The loss of dopamine causes the movement symptoms seen in people with Parkinsons disease.
People with Parkinsons disease also lose another neurotransmitter called norepinephrine. This chemical is needed for proper functioning of the sympathetic nervous system. This system controls some of the bodys autonomic functions such as digestion, heart rate, blood pressure and breathing. Loss of norepinephrine causes some of the non-movement-related symptoms of Parkinsons disease.
Scientists arent sure what causes the neurons that produce these neurotransmitter chemicals to die.

Side Effects And Problems Of Anticholinergics
Another reason these drugs are not a first choice for treating Parkinsons are their side effects. Some people may experience confusion, a dry mouth, constipation and blurred vision when taking anticholinergics.
Anticholinergics may interfere with levodopa absorption in the small bowel, which reduces the effectiveness of Madopar or Sinemet, forms of the drug levodopa.
Side Effects Of Medication
All prescribed medication can have potential side effects, including those used to treat Parkinsons.
Many people find their Parkinsons medication works very well when they start taking it, but this may change over time and side effects can develop.
Some things you think are symptoms of Parkinsons may actually be side effects of medication.
Some peoples side effects will have a big impact on their lives and have to be kept under control along with the symptoms.

What Future Medications May Be Available For Parkinsons
There are numerous studies investigating new treatments for Parkinsons disease.
There has been new information about the role of autoimmunity and T-cells in the development of Parkinsons disease, possibly opening the door to a role for biologics.
Stem cells are also being investigated as a treatment option for Parkinsons disease.
What Are The Different Stages Of Parkinsons Disease
Each person with Parkinsons disease experiences symptoms in in their own unique way. Not everyone experiences all symptoms of Parkinsons disease. You may not experience symptoms in the same order as others. Some people may have mild symptoms others may have intense symptoms. How quickly symptoms worsen also varies from individual to individual and is difficult to impossible to predict at the outset.
In general, the disease progresses from early stage to mid-stage to mid-late-stage to advanced stage. This is what typically occurs during each of these stages:
Early symptoms of Parkinsons disease are usually mild and typically occur slowly and do not interfere with daily activities. Sometimes early symptoms are not easy to detect or you may think early symptoms are simply normal signs of aging. You may have fatigue or a general sense of uneasiness. You may feel a slight tremor or have difficulty standing.
Often, a family member or friend notices some of the subtle signs before you do. They may notice things like body stiffness or lack of normal movement slow or small handwriting, lack of expression in your face, or difficulty getting out of a chair.
Standing and walking are becoming more difficult and may require assistance with a walker. You may need full time help to continue to live at home.

How Dopamine Agonists Are Used
Dopamine agonists are used at all stages of Parkinsons. You might take them alone when treatment is being started, or alongside levodopa to provide a more effective treatment with fewer side effects.
Treatment with dopamine agonists has to be started carefully to minimise the risk of side effects, with the dose gradually increasing until you and your specialist or Parkinsons nurse are happy that your symptoms are under control. Some dopamine agonists are available as one a day tablets. These can be a better option for the body and may help both movement and other symptoms of Parkinsons.
Medications Used To Treat Parkinson’s Disease
Nice To Know:
A few important comments before describing the medications for Parkinson’s Disease
- Drug therapy for Parkinson’s disease, and the choice of drugs used for the treatment of Parkinson’s disease, should be a joint decision between the person with Parkinson’s disease and the physician, based on the severity of symptoms and their impact on quality of life.
- It is emphasized that treatment for Parkinson’s disease should always be individually tailored for each person.
- Never compare your treatment schedules with those of other people with Parkinson’s Disease. You are all different.
Properly selected medications with the correctly tailored dose form the mainstay of treatment of Parkinson’s Disease.
Drugs currently used to treat Parkinson’s Disease make movement easier and can prolong function for many years. Medications aim to replace or mimic the missing chemical dopamine in the brain.
The following are the medications used in the treatment of Parkinson’s Disease. Each will be considered below.

How Is Parkinsons Disease Diagnosed
Diagnosing Parkinsons disease is sometimes difficult, since early symptoms can mimic other disorders and there are no specific blood or other laboratory tests to diagnose the disease. Imaging tests, such as CT or MRI scans, may be used to rule out other disorders that cause similar symptoms.
To diagnose Parkinsons disease, you will be asked about your medical history and family history of neurologic disorders as well as your current symptoms, medications and possible exposure to toxins. Your doctor will look for signs of tremor and muscle rigidity, watch you walk, check your posture and coordination and look for slowness of movement.
If you think you may have Parkinsons disease, you should probably see a neurologist, preferably a movement disorders-trained neurologist. The treatment decisions made early in the illness can affect the long-term success of the treatment.
What Should I Know About Parkinsons Disease And Medications
There have been rapid and remarkable changes over the past decade in treating Parkinsons disease . The development of new medicines and the understanding of how best to use them and the older drugs have significantly improved the quality of life for people with the disease.
There is currently no treatment that has been proven to affect the disease progression or development of medication that can slow the disease process. There are two general approaches to the treatment of PD improve the symptoms with medications and engage in physical therapy. Most patients with PD can be adequately treated with medicines that alleviate their symptoms. For the approximately 15% of patients for whom medicines are not sufficiently effective, new, highly effective, and safe surgical treatments are available.
Choices about medicines made early in the course of the disease have a strong impact on the long-term course of the illness. Therefore, you should seek the advice of doctors specially trained in treating PD even when the illness is only suspected. Movement disorders specialists are neurologists who have completed their training in neurology and have received special advanced training in treating PD and other related diseases.

Is Parkinsons Disease Inherited
Scientists have discovered gene mutations that are associated with Parkinsons disease.
There is some belief that some cases of early-onset Parkinsons disease disease starting before age 50 may be inherited. Scientists identified a gene mutation in people with Parkinsons disease whose brains contain Lewy bodies, which are clumps of the protein alpha-synuclein. Scientists are trying to understand the function of this protein and its relationship to genetic mutations that are sometimes seen in Parkinsons disease and in people with a type of dementia called Lewy body dementia.
Several other gene mutations have been found to play a role in Parkinsons disease. Mutations in these genes cause abnormal cell functioning, which affects the nerve cells ability to release dopamine and causes nerve cell death. Researchers are still trying to discover what causes these genes to mutate in order to understand how gene mutations influence the development of Parkinsons disease.
Scientists think that about 10% to 15% of persons with Parkinsons disease may have a genetic mutation that predisposes them to development of the disease. There are also environmental factors involved that are not fully understood.
What Lifestyle Changes Can I Make To Ease Parkinsons Symptoms
Exercise: Exercise helps improve muscle strength, balance, coordination, flexibility, and tremor. It is also strongly believed to improve memory, thinking and reduce the risk of falls and decrease anxiety and depression. One study in persons with Parkinsons disease showed that 2.5 hours of exercise per week resulted in improved ability to move and a slower decline in quality of life compared to those who didnt exercise or didnt start until later in the course of their disease. Some exercises to consider include strengthening or resistance training, stretching exercises or aerobics . All types of exercise are helpful.
Eat a healthy, balanced diet: This is not only good for your general health but can ease some of the non-movement related symptoms of Parkinsons, such as constipation. Eating foods high in fiber in particular can relieve constipation. The Mediterranean diet is one example of a healthy diet.
Preventing falls and maintaining balance: Falls are a frequent complication of Parkinson’s. While you can do many things to reduce your risk of falling, the two most important are: 1) to work with your doctor to ensure that your treatments whether medicines or deep brain stimulation are optimal and 2) to consult with a physical therapist who can assess your walking and balance. The physical therapist is the expert when it comes to recommending assistive devices or exercise to improve safety and preventing falls.

Parkinson’s Pain Can Be Linked To Depression
If exercise and/or adjusting your medications do not help with the pain, ask yourself and your doctor if you might be depressed. Pain in Parkinson’s disease is linked to depression, and treating the depression may help to diminish any persistent pains. Depression affects about 40% of people with Parkinson’s. In some cases, psychotherapy may alleviate pain from Parkinson’s.
If you don’t have depression or if the pains persist after treating your symptoms of depression, then you may want to consider seeing a pain specialist before taking over-the-counter remedies. Pain control specialists have a whole array of pain control treatments and techniques, ranging from special medications to special surgical procedures, that are known to be effective.
Your Parkinson’s Drug Treatment
Dopamine is a chemical messenger made in the brain. The symptoms of Parkinsons appear when dopamine levels become too low. This is because many of the cells in your brain that produce dopamine have died or are dying. Taking dopamine as a drug doesnt work because it cannot cross the blood brain barrier. To get around this, doctors use other medication that can act in a similar way.
Looking Out For Side Effects If You’re A Carer
If youre a carer of someone with Parkinsons, medication side effects can be difficult and tiring to cope with.
It may be that the person having side effects such as hallucinations and delusions or impulsive and compulsive behaviour does not realise they are experiencing them.
Its important to seek help from your specialist as soon as you can.
Treatments And Outcomes Of Dip
DIP is generally treated by cessation of the offending drugs. Patients who cannot stop taking antipsychotic drugs because of their psychiatric diseases, such as those with schizophrenia or major depressive disorders, may be switched to atypical antipsychotics that have a lower risk of EPS. People who are prescribed dopamine antagonists due to simple GI disturbance, headache, dizziness, or insomnia should stop taking the offending drugs as soon as possible. Anticholinergics including trihexyphenidyl, benztropine, amantadine, and levodopa have been empirically tested for their ability to relieve symptoms of DIP, but this has produced no clear evidence of their effects in DIP patients.,,,,

Impulsive And Compulsive Behaviour
A small number of people taking levodopa have problems with impulsive or compulsive behaviour. This can also be called impulse control disorder. It affects a much smaller percentage of people taking levodopa than those taking dopamine agonists, but it is still a possible side effect. Further information is available at Compulsive and impulsive behaviour.
Another potential problem is dopamine dysregulation syndrome, where someone with Parkinsons might be tempted to take more of their Parkinsons medication than they are prescribed. If you think this is happening to you or the person you are caring for, tell your GP, specialist or Parkinsons nurse right away.
It is important that all people with Parkinsons are monitored for any potential risk of impulsive and compulsive behaviour while being treated with levodopa.
People with Parkinsons, their carers, friends and family members should work with healthcare professionals to monitor any changes in behaviour. If you start to experience these symptoms, you should discuss it with your specialist or Parkinsons nurse immediately. You should not stop taking the medication.
Controlled Release Madopar And Sinemet
Controlled release preparations have the letters CR or HBS after the drug name.
These let the levodopa enter your body slowly instead of all at once. They can increase the time between doses.
They may be used when the dose of standard levodopa starts to wear off and the person taking it no longer feels the treatment is effective.
Controlled release options can sometimes reduce involuntary movements .
