Types Of Parkinsons Medication
There is currently no cure for Parkinsons, but medication can usually provide good symptom control for a long time. Meanwhile researchers continue to search for a cure, and research into new and improved medicines continues.
Dopamine is a chemical messenger made in the brain. The symptoms of Parkinsons are largely associated with a decrease in the levels of this chemical, due to the death of the nerve cells that make it.
Unfortunately, taking dopamine as a drug treatment would not help you, because it cannot cross into your brain where it is needed. There are a number of approaches that can be taken to try to compensate for the dopamine deficit and therefore alleviate the symptoms of the condition. Ultimately these will increase the levels of dopamine and help to overcome some of the symptoms of the condition. However, many of the medications may have side effects which should be taken into account when being prescribed.
A wide range of Parkinsons medications is available. These may be taken in many different forms. Your doctor will try to find the medication that is most suitable for you throughout your Parkinsons treatment. What is available will also depend on the country in which you live.
How Are Parkinsons Tremors Treated
Tremor can be unpredictable. Some experts say itâs the toughest symptom to treat with medication. Your doctor may prescribe medication for your tremors:
- Levodopa/carbidopa combination medicines . This treatment is a type of medication called a dopamine agonist. Itâs usually the first treatment for Parkinsonâs.

Some Disadvantages Of Mao
When selegiline is taken together with levodopa, side effects such as dyskinesias , hallunications or vivid dreaming may sometimes occur or worsen.
When people have taken rasagiline on its own , the most commonly reported side effects have been:
When taken with levodopa, the most common reports have been of uncontrolled movements and accidental falls.
Many of these side effects may be due to the increase in dopamine caused by rasagiline or selegiline. Your doctor or consultant can alter the dosage to correct these effects.
If youre taking some types of antidepressant, you might not be able to take MAO-B inhibitors, as these drugs can interact with each other to raise blood pressure to a dangerous level.
Your neurologist or pharmacist is the best person to advise on potential interactions with other medications.

Managing The Social And Emotional Impact
The effects of PD are broad and impact on the social and economic life of the person and their family from the time of diagnosis in a variety of ways.
Coping and adjusting to the diagnosis, facing increasing challenges at work and planning for the future can be a daunting undertaking.
Navigating this newfound uncertainty requires careful consideration and appropriate specialised support.
As the disorder progresses, caregiver burden also increases and quality of life can decrease.
A social worker specialised in movement disorders such as PD can assist the person with PD, their caregiver and family negotiate the challenges faced across the life time of the persons PD.
Social workers are highly skilled professionals who can assist you and your loved ones by:
- providing a range of different therapys like counselling
- assistance with linking to other support services
- directing you to financial support services
- information provision of entitlements for care packages
- help to facilitate suitable respite arrangements for the caregiver
- assistance and support with navigating the pathway to permanent residential care if the need arises.
After receiving a diagnosis of PD it is normal to experience a change in mood. A social worker has the appropriate specialised skills to help you deal with the reaction to your diagnosis.
Social workers are specifically trained to support you in understanding how best to manage such symptoms.
Medication Guidelines For Parkinson’s Disease
There is no one best mix of Parkinsonâs medicines. You and your doctor will have to try a few treatment approaches to figure out the best one for you.
But there are some general guidelines for taking your medication. Be sure to ask your doctor or pharmacist for any specific tips for your treatment.

Treatment Of Late Stage Complications Of Parkinsons Disease
Postural hypotension
Levodopa and dopamine agonists worsen postural hypotension and it may be necessary to lower the dose of levodopa or withdraw the agonist. Treatment is difficult, but patients should be advised to sleep with the head of the bed raised by one or two bricks and to add salt to their diet. Fludrocortisone can then be added at a dose of 0.1 mg in the morning, increasing if necessary up to 0.5 mg in the morning. If these measures are ineffective, the alpha agonist midodrine 10-20 mg four hourly can be useful but it is experimental and only available via the Special Access Scheme. Patients treated for postural hypotension need to have electrolytes, renal function and supine blood pressures closely monitored.
Parkinsonian psychosis, depression and dementia
Psychotic symptoms such as visual hallucinations and persecutory delusions occur most commonly in the setting of dementia, which may be mild and therefore easily missed. Most drugs for Parkinsons disease make these symptoms worse. Depression is also common and requires treatment in its own right.
Exploring Seven Recently Approved Parkinsons Treatments
Remarkably, in the last five years, seven new medications have been approved for the treatment of the motor symptoms of Parkinsons disease , with two approved in 2020. Thats exciting progress! And while it is great to have so many choices, the various options can be confusing so today I will describe these new medications and their uses.

Dopamine Replenishment Remains The Key To Symptomatic Treatment
Parkinson disease has long been synonymous with cerebral dopamine depletion, and dopamine replenishment remains the fundamental substrate for medical treatment. Both motor and nonmotor symptoms reflect loss of the nigrostriatal dopaminergic system, and these symptoms often respond dramatically to dopamine restoration. However, it is now well-recognized that PD involves much more than loss of dopamine. Other neurotransmitter systems are not only affected late in PD but also early, preceding PD motor symptoms. Early symptoms such as rapid eye movement sleep behavior, olfactory loss, anxiety, or dysautonomia may develop 20 or more years before recognizable PD.4 The temporal course of PD, spanning decades, has been formalized in the Braak staging scheme.5
Although PD is now understood to be much more than a dopamine deficiency state, most of the therapeutic gains are achieved through restoring brain dopamine neurotransmission. Understanding how best to accomplish this is key to managing PD.
How Can People Cope With Parkinsons Disease
While PD usually progresses slowly, eventually daily routines may be affectedfrom socializing with friends to earning a living and taking care of a home. These changes can be difficult to accept. Support groups can help people cope with the diseases emotional impact. These groups also can provide valuable information, advice, and experience to help people with PD, their families, and their caregivers deal with a wide range of issues, including locating doctors familiar with the disease and coping with physical limitations. A list of national organizations that can help people locate support groups in their communities appears at the end of this information. Individual or family counseling may also help people find ways to cope with PD.
People with PD may also benefit from being proactive and finding out as much as possible about the disease in order to alleviate fear of the unknown and to take a positive role in maintaining their health. Many people with PD continue to work either full- or part-time, although they may need to adjust their schedule and working environment to accommodate their symptoms.

A New Era For Parkinsons Disease Treatment
A non-invasive ultrasound treatment for Parkinsons disease that was tested in a pivotal trial led by University of Maryland School of Medicine researchers is now broadly available at the University of Maryland Medical Center .
Howard Eisenberg, MD, Dheeraj Gandhi, MD, MBBS, Paul Fishman, MD, PhD, Bert W. OMalley, MD.
The device, called Exablate Neuro, was approved in November by the U.S. Food and Drug Administration to treat advanced Parkinsons disease on one side of the brain. The approval was based on findings from the UMSOM clinical trial and effectively expands access to focused ultrasound beyond clinical trial participation.
Rapid Reversal of Symptoms
Focused ultrasound is an incisionless procedure, performed without the need for anesthesia or an in-patient stay in the hospital. Patients, who are fully alert, lie in a magnetic resonance imaging scanner, wearing a transducer helmet. Ultrasonic energy is targeted through the skull to the globus pallidus, a structure deep in the brain that helps control regular voluntary movement. MRI images provide doctors with a real-time temperature map of the area being treated. During the procedure, the patient is awake and providing feedback, which allows doctors to monitor the immediate effects of the tissue ablation and make adjustments as needed.

How Do I Take Care Of Myself
If you have Parkinsons disease, the best thing you can do is follow the guidance of your healthcare provider on how to take care of yourself.
- Take your medication as prescribed. Taking your medications can make a huge difference in the symptoms of Parkinsons disease. You should take your medications as prescribed and talk to your provider if you notice side effects or start to feel like your medications arent as effective.
- See your provider as recommended. Your healthcare provider will set up a schedule for you to see them. These visits are especially important to help with managing your conditions and finding the right medications and dosages.
- Dont ignore or avoid symptoms. Parkinsons disease can cause a wide range of symptoms, many of which are treatable by treating the condition or the symptoms themselves. Treatment can make a major difference in keeping symptoms from having worse effects.

New Medications For Off Time
A number of new medications approved recently are designed to reduce OFF time. These medications fall into two major categories:
- Medications that lengthen the effect of a carbidopa/levodopa dose
- Medications that are used as needed if medication effects wear off
Well give specific examples below. In general, new medications that extend the length of a carbidopa/levodopa dose are used if OFF time is somewhat predictable and occurs prior to next dose. New medications that are used as needed are most beneficial when OFF time is not predictable.
New medications that lengthen the effect of a dose of carbidopa/levodopa
- Istradefylline is an adenosine A2A receptor antagonist which was approved in the US in 2019 as an add-on therapy to levodopa for treatment of OFF time in PD. Unlike many of the other medications, it has a novel mechanism of action and is the first medication in its class to be approved for PD. It acts on the adenosine receptor, which modulates the dopaminergic system, but is not directly dopaminergic. The drug was developed in Japan and underwent clinical trials both in Japan and in the US.
- Opicapone is a catechol-O-methyltransferase inhibitor that is taken once a day. It was approved in the US in 2020 as an add-on therapy to levodopa for motor fluctuations.

What Medications Are Used To Treat Parkinsons Symptoms
Since many of the motor symptoms of Parkinsons are the result of a lack of dopamine in the brain, most drugs used to treat Parkinsons are aimed at temporarily replenishing or imitating dopamine. The following list is a guide to medications approved by Health Canada to treat symptoms of Parkinsons1. Speak to your doctor for detailed information regarding effectiveness and side effects of a particular drug.
Levodopa
- Converted into dopamine in the brain and stored in nerve cells to replace depleted dopamine
- Combined with another drug, carbidopa or benzerazide, allows more levodopa to get to the brain and reduces side effects
- Helps improve muscle rigidity and movement
- Side effects include dyskinesias
- Over years of use, may be associated with wearing off
Dopamine Agonists
- Can reduce dyskinesias and improve wearing off

Reversing Parkinsons Through Diet
What is the best nutrional plan for Reversing Parkinsons Through Diet? The Ketogenic Parkinsons Diet is by far the best diet for Parkinsons Disease as well as most neurological conditions. The Ketogenic Diet dramatically improves Parkinsons Disease. Like most diseases or conditions, what you put into your body matters quite a bit. The holistic treatment for Parkinsons Disease begins with keeping your natural dopamine levels in proper balance.
Implementing a low carb, low sugar diet will keep the acidic sugars from interfering with your brain chemistry and causing over excitation of your brain neurons. It is a big part of the natural Parkinsons disease treatment and works well with the natural remedies for Parkinsons shown at the bottom of this page.
Dr. Otto Warburg proved that disease cant form or live in an alkaline body. If you have been diagnosed with a neurological condition like Parkinsons, then you will want to look into getting an alkaline Water Ionizer! Alkaline Water Ionizers make oxygen rich, antioxidant rich, electrolyte rich, micro clustered and hexagonal super healing drinking water that prevents nerve degenerative based diseases like Parkinsons Disease from taking hold in your body!
Pain Is A Common But Overlooked Problem In Parkinsons Disease
Pain is an often overlooked non-motor symptom of Parkinsons disease . Studies show that between 40-80% of people with PD report pain, which is likely why it is often suggested as a topic for this blog.
One of the reasons why the topic of pain and PD is difficult to address is that it is sometimes tough to discern whether a particular pain is due to PD or not. Chronic pain is such a common symptom among the general population, and people with PD are not immune to common problems as well. However, there are aspects of PD that may exacerbate the pain experienced from a common problem. In addition, there are particular types of pain that may be unique to people with PD.

Mechanism Of Action Of Available Drugs
The major classes of drugs currently available for the treatment of idiopathic Parkinsons disease are shown in Table 1. Many aim to increase dopamine in the brain, by increasing its production or altering its metabolism .

Drugs with alter metabolism in boxed red italics
Levodopa
Levodopa is absorbed from the small intestine and transported into the brain where it is converted to dopamine. Levodopa has a short plasma half-life of about one hour. Early in Parkinsons disease, levodopa has a long duration of action which is independent of plasma concentration, but as the disease progresses, the duration of the effect reduces. The short-duration effect is strongly linked to plasma concentration and lasts, at most, hours.
Slow-release preparations are gradually absorbed, resulting in more sustained plasma concentrations. They have reduced bioavailability higher doses are required to match the benefit of an equivalent strength of a standard preparation. Rapid release preparations are taken in liquid form to enhance passage through the stomach and absorption from the small intestine.
Dopamine agonists
Apomorphine is a potent emetic so patients must be pre-treated with domperidone 20 mg three times daily orally for at least 48 hours before the first injection. Domperidone should be continued for at least a few weeks once regular intermittent treatment has commenced. The dose can then be tapered slowly as tolerance to the emetic effects of apomorphine usually develops.
Side Effects Talk To Your Doctor Or Pharmacist
Like any medicines, Parkinson’s medicines can give you side effects. If you get side effects from your Parkinson’s medicines, tell your doctor or pharmacist. Common side effects include nausea , light-headedness, leg swelling and sleep problems. Also let them know if you think your medicines are causing confusion, hallucinations or involuntary movements. Some people have an unusual desire to gamble or engage in other obsessive behaviours. Tell your doctor if you experience any side effects, they may adjust the amount of medicine you take or you may be given another type. It is important that you don’t stop taking your Parkinsons medicines until you are advised to do so.

What Are The Early Warning Signs Of Parkinsons Disease
Parkinsons warning signs can be motor symptoms like slow movements, tremors or stiffness. However, they can also be non-motor symptoms. Many of the possible non-motor symptoms can appear years or even decades ahead of motor symptoms. However, non-motor symptoms can also be vague, making it difficult to connect them to Parkinsons disease.
Non-motor symptoms that might be early warning signs include:
- Sleep problems such as periodic limb movement disorder , rapid eye movement behavior disorder and restless legs syndrome.
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.
