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.
Complementary And Alternative Medicine And Over
With Parkinsons, exercise is better than taking a bottle of pills. If you dont do anything youll just stagnate. Brian Lambert
With Parkinsons you have two choices: You can let it control you, or you can control it. And Ive chosen to control it. US Senator Isakson
Introduction: Having one of the numerous neurodegenerative disorders can be disheartening, difficult and life-threatening/ending however, Parkinsons remains in the forefront of treatment schemes and therapeutic options. We may have a slowly evolving disorder, yet I remain firmly entrenched both in striking back to try-to-slow its progression and in remaining hopeful that new advances are on the horizon to throttle-back its progression. Recently, several people have asked for an update on my strategy for treating Parkinsons. My plan consists of traditional Parkinsons medication, supplemented by a complementary and alternative medicine approach, and fueled by exercise. My philosophy is simple because I truly believe there are steps I can follow to remain as healthy as possible, which include having a positive mindset to support this effort, and to accept the axiom of the harder I try the better Ill be.
Life is to be lived even if we are not healthy. David Blatt
My way of dealing with Parkinsons is to keep myself busy and ensure my mind is always occupied. David Riley

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.

Smartphone Automated Audiogram Image Recognition Found To Have Low Accuracy
The automated audiogram image recognition feature in the iPhone has low accuracy, according to a research letter published online Jan. 5 in JAMA Otolaryngology-Head & Neck Surgery.
The researchers found that the accuracy of the automated audiogram image recognition was 7.0 and 11.8 percent for right and left ears, respectively. For more than 80 percent of ears, the feature was unable to detect adequate thresholds to calculate pure-tone average, prompting the user to manually enter the audiogram data. When hearing was asymmetric, accuracy was significantly higher . Accuracy was not associated with type, degree of hearing loss, or number of missing thresholds.
“Future efforts will be needed to improve the accuracy of automated audiogram image recognition if this approach is used for the customization of future over-the-counter hearing aids,” the authors write.
One author disclosed financial ties to Apple and the regenerative medicine industry.

Levodopa: The Most Effective Drug For Treating Parkinsons
Levodopa, also known as L-DOPA, has long been, and continues to be, the most effective drug in treating Parkinsons disease symptoms. Most people with Parkinsons disease will take this drug at some point. There are side effects that can occur with Levodopa including nausea, fatigue and orthostatic hypotension. Often these side effects can be successfully treated so that Levodopa can be tolerated better. In addition, as the disease progresses and the brain has less ability to produce and process dopamine, dyskinesias, or involuntary movements can develop from Levodopa.

Why Is This Medication Prescribed
The combination of levodopa and carbidopa is used to treat the symptoms of Parkinsons disease and Parkinsons-like symptoms that may develop after encephalitis or injury to the nervous system caused by carbon monoxide poisoning or manganese poisoning. Parkinsons 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.
Medication Names And Forms
Most medications have two names. The generic name describes the active ingredient in the drug. Every drug that has the same active ingredient will have the same generic name, no matter who manufactures it. The different drug companies who produce the medication market it using a brand or trade name and these may vary from country to country.
For example, the levodopa group of drugs can exist in a number of forms. Each of these contains the chemical levodopa in combination with a second chemical called carbidopa. Together, these are referred to as co-careldopa.

How Should This Medicine Be Used
The combination of levodopa and carbidopa comes as a regular tablet, an orally disintegrating tablet, an extended-release tablet, and an extended-release capsule to take by mouth. The combination of levodopa and carbidopa also comes as a suspension to be given into your stomach through a PEG-J tube or sometimes through a naso-jejunal tube using a special infusion pump. The regular and orally disintegrating tablets are usually taken three or four times a day. The extended-release tablet is usually taken two to four times a day. The extended-release capsule is usually taken three to five times a day. The suspension is usually given as a morning dose and then as a continuous dose , with extra doses given no more than once every 2 hours as needed to control your symptoms. Take levodopa and carbidopa at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take levodopa and carbidopa exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release tablets whole do not chew or crush them.
To take the orally disintegrating tablet, remove the tablet from the bottle using dry hands and immediately place it in your mouth. The tablet will quickly dissolve and can be swallowed with saliva. No water is needed to swallow disintegrating tablets.
Which Medication Will I Take
You will be prescribed levodopa, a dopamine agonist or an MAO-B inhibitor. Which medication you take depends on how much your symptoms affect you and other factors, such as your age and your lifestyle.
Most people find they tolerate their treatment well and will return to clinic after six to eight weeks to review their response. This is when your specialist or Parkinsons nurse will increase or decrease the doses, the frequency, or add new drugs until your symptoms are as controlled as possible.
Before leaving the clinic you should get the contact details of your Parkinsons nurse or the number of the clinic in case you have any problems with side effects.

What Should I Do If I Forget A Dose
Take the missed dose of the regular tablet, orally disintegrating tablet, extended-release tablet, or extended-release capsule as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
If you are using levodopa and carbidopa enteral infusion and will be disconnecting the infusion pump for a short time , other than the normal nightly disconnection, ask your doctor if you should use an extra dose before you disconnect the pump. If the infusion pump will be disconnected for longer than 2 hours, call your doctor you probably will be advised to take levodopa and carbidopa by mouth while you are not using the suspension.

An Approach To The Treatment Of Parkinson’s Disease
No treatment can arrest or slow neurodegeneration in Parkinson’s disease. The aim is to relieve symptoms and avoid the complications of therapy.
Early Parkinson’s disease
Many studies have shown that early treatment with dopamine agonists reduces the incidence of dyskinesia.1Fewer motor fluctuations were shown in some but not all of the studies. We recommend a dopamine agonist as the first treatment in younger patients who have mild disease and no cognitive deficit. It is necessary to add levodopa within 1-5 years in most patients. In more severe disease, treatment begins with levodopa but a dopamine agonist may be added to keep the daily dose of levodopa in the lower range if there is no cognitive deficit. Dopamine agonists are used infrequently and with caution in patients more than 70 years old because of the risk of neuropsychiatric adverse effects and postural hypotension. They are contraindicated in the presence of dementia.
Isolated resting tremor is rarely disabling, but if it interferes with function it can usually be managed with levodopa. When this is ineffective at low to moderate doses, the addition of an anticholinergic can sometimes be useful.

Levodopa is a chemical building block that your body converts into dopamine in the brain.
Levodopa already occurs naturally in your body and taking it as a drug treatment boosts the supply, meaning the nerve cells can make more dopamine.
Levodopa drugs are sometimes one of the first types of medication that people with Parkinsons are prescribed. However, this will not be the same for everyone.
Your levodopa treatment will usually start with a low dose. This will gradually be increased until your symptoms are under control.
Levodopa can help treat Parkinsons symptoms because it helps to top up dopamine levels in the brain.
You may experience a big improvement in your symptoms when taking it, especially with stiffness and slowness of movement.
Levodopa becomes less effective over time. This is because it cannot stop the dopamine-producing cells from being lost so you will continue to get symptoms. This means that more frequent doses are needed.
Your brain cant become resistant to levodopa. People with Parkinsons will benefit from medications containing levodopa throughout their lifetime.
The patient information leaflet that comes with your drugs will tell you the full range of side effects that you may experience but some possible ones include:
Wearing off
Involuntary movements

Managing Your Parkinson’s Medication
At first you may be prescribed only low doses of Parkinson’s medication. Or your doctor may suggest you delay taking medication until symptoms increase. This is because medicines may become less effective over time, or cause side effects. Over time as Parkinsons progresses, your symptoms will change. Your specialist may gradually increase the dose and add new medications to control symptoms as effectively as possible.
Your doctor or Parkinsons nurse will advise the times of day you should take the medication so that it works best for you.
Important! It is very important to keep to the daily dose prescribed by your doctor and follow any instructions you are given. Following your medication regime carefully is a key part of effectively managing your Parkinsons. Work closely with your doctor to agree your treatment regime, so that you are comfortable with what you need to take, when and how.
If you do not take the right dose of medication at the right time, it could mean that your symptoms are not well controlled. This could not only impact on your quality of life but it could also increase the need for further treatment. It could also waste public money spent on healthcare.

Common Drugs For Parkinson’s Disease
Levodopa and carbidopa . Levodopa is the most commonly prescribed medicine for Parkinsonâs. Itâs also the best at controlling the symptoms of the condition, particularly slow movements and stiff, rigid body parts.
Levodopa works when your brain cells change it into dopamine. Thatâs a chemical the brain uses to send signals that help you move your body. People with Parkinsonâs donât have enough dopamine in their brains to control their movements.
Sinemet is a mix of levodopa and another drug called carbidopa. Carbidopa makes the levodopa work better, so you can take less of it. That prevents many common side effects of levodopa, such as nausea, vomiting, and irregular heart rhythms.
Sinemet has the fewest short-term side effects, compared with other Parkinsonâs medications. But it does raise your odds for some long-term problems, such as involuntary movements. An inhalable powder form of levodopa and the tablet istradefylline have been approved for those experiencing OFF periods, OFF periods can happen when Parkinsonâs symptoms return during periods between scheduled doses of levodopa/carbidopa.
People who take levodopa for 3-5 years may eventually have restlessness, confusion, or unusual movements within a few hours of taking the medicine. Changes in the amount or timing of your dose will usually prevent these side effects.
Dopamine agonists. These drugs act like dopamine in the brain. They include pramipexole , rotigotine , and ropinirole .

Impulsive And Compulsive Behaviours
People who experience impulsive and compulsive behaviours cant resist the temptation to carry out an activity often one that gives immediate reward or pleasure.
Behaviours may involve gambling, becoming a shopaholic, binge eating or focusing on sexual feelings and thoughts. This can have a huge impact on peoples lives including family and friends.
Not everyone who takes Parkinsons medication will experience impulsive and compulsive behaviours, so these side effects should not put you off taking your medication to control your symptoms.
If you have a history of behaving impulsively you should mention this to your GP, specialist or Parkinsons nurse.
Asking your specialist to make changes to your medication regime or adjusting the doses that you take is the easiest way to control impulsive and compulsive behaviours. So, if you or the person you care for is experiencing this side effect, tell your healthcare professional as soon as possible before it creates large problems.
If you are not able to get through to your healthcare professional straight away, you can call our Parkinsons UK helpline on 0808 800 0303.
We have advice that can help you manage impulsive and compulsive behaviours as well as information on what behaviour to look out for.
Names Of Parkinsons Drugs
Drugs for Parkinsons can be divided into three categories.
On our website, we have listed drugs in the following order to help you see each category clearly.
- The class or type of drug, for example levodopa.
- The generic name, such as co-beneldopa, which will include the active ingredients of the drug. For example, co-beneldopa is a combination of levodopa and benserazide.
- The brand name. For example, Madopar is the name that the pharmaceutical company, Roche, uses to sell co-beneldopa.
Your specialist will decide whether to prescribe you branded or generic versions of your medication. It usually depends on which area of the country you are in or what is most common to prescribe in that area. Once there are no longer any legal rights to the brand name any company can make generic versions of a drug.
The active ingredient of a generic drug is always the same as the branded version and lots of people wont have any problems using the generic medication.
In the UK, a generic or branded medicine needs a licence and there is a strict process for this. This means that the quality of a generic or branded version of the same medicine will be the same, and they will also act in the same way.
If you find that you respond a bit differently to generic medication, discuss this with your specialist or Parkinsons nurse.
The brand name will usually be the most visible name on your packet of medication. The generic name is usually written in small print.
