Types Of Parkinson’s Medication

What Are The Common Side Effects

Are there different types of Parkinson’s?

Common side effects of carbidopa-levodopa include:

Common side effects of dopamine agonists include:

  • Compulsive behaviors such as hypersexuality, gambling, and eating

Common side effects of monoamine oxidase B inhibitors include:

Common side effects of catechol O-methyltransferase inhibitors include:

  • Increased risk of involuntary movements

Common side effects of anticholinergics include:

  • Impaired memory
  • Impaired urination

This is not a complete list of side effects and other serious side effects or health problems that may occur because of the use of this drug. Call your doctor for medical advice about serious side effects or adverse reactions. You may report side effects or health problems to the FDA at 1-800-FDA-1088.

Causes Of Parkinsons Disease

At present, we do not know the cause of Parkinsons disease. In most people there is no family history of Parkinsons Researchers worldwide are investigating possible causes, including:

  • environmental triggers, pesticides, toxins, chemicals
  • genetic factors
  • combinations of environment and genetic factors

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.

Medication For Parkinsons Disease

Once the doctor diagnoses Parkinsons disease, the next decision is whether a patient should receive medication, which depends on the following:

  • The degree of functional impairment

  • The degree of cognitive impairment

  • Ability to tolerate antiparkinsonian medication

  • The advice of the attending doctor

No two patients react the same way to a given drug, therefore, it takes time and patience to find an appropriate medication and dosage to alleviate symptoms.

Treatment Of Late Stage Complications Of Parkinson’s Disease

Drugs Used In Parkinson

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 Parkinson’s disease make these symptoms worse. Depression is also common and requires treatment in its own right.

Symptomatic Treatment Of Motor Symptoms

Levodopa

A majority of patients with PD require levodopa therapy within 2 years of symptom onset. Levodopa, the most effective drug in the treatment of PD, is almost always combined with carbidopa or benserazide, aromatic acid decarboxylase inhibitors that prevent its peripheral metabolism and markedly reduce the risk of nausea. Increasing the ratio of carbidopa:levodopa from the current standard 1:4 has been shown to increase on time without dyskinesia and reduce off time.

The global antiparkinsonian efficacy of levodopa is so predictable that a positive therapeutic response is used to support the diagnosis of PD. Adverse effects of levodopa include nausea and vomiting, orthostatic hypotension, sedation, confusion, sleep disturbance, hallucinations and dyskinesias. There are many different types of dyskinesia but peak-dose chorea or stereotypy and wearing off dystonia are most common. About half of the patients experience wearing off, and a third experience dyskinesias within 2 years after initiation of levodopa therapy. Latency from ingestion of levodopa to observable therapeutic benefit can be shortened by taking levodopa on an empty stomach , avoiding or reducing protein intake, or by crushing the levodopa tablet and mixing it with a carbonated beverage.

Other drugs

Besides levodopa, there are many other types of medications available for the treatment of PD-related motor symptoms: anticholinergics, amantadine, MAOIs, COMTIs, dopamine agonists and istradefylline.

Side Effects And Problems With Levodopa

In the early days of taking levodopa, you may feel sickness or nausea. In most people this will pass as your body adjusts to the medication.

Overtime as Parkinsons progresses the levodopa dose will need to be adjusted. Many people will become more aware that symptoms sometimes return between doses of medication. This is called wearing off and is a sign your dose needs to be adjusted.

As levodopa is absorbed through the gut, constipation or other stomach problems may impact on uptake of the medication. In some people who have had Parkinsons for sometime extra involuntary movements can occur. Your neurologist will be able to help adjust medications to minimise dyskinesia.

Other side effects may include:

Side effects of levodopa can sometimes be improved by changing your dose, the form of the drug or how often you take it. If this doesnt work, other types of drug may be combined with levodopa.

Speak to your GP or specialist about the right treatment for you.

Your Parkinsons 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.

Which Medication Will I Take

My Parkinson’s Story: Medications

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.

Treatment For Associated Issues

Medical problems such as depression, insomnia, pseudobulbar affect , dementia, and others are common in people with Parkinsons disease. As such, you may require treatment to manage them in addition to whats prescribed for your Parkinsons symptoms.

Your doctor may recommend OTC therapies for various symptoms and complications of Parkinsons disease. For example:

  • Pain relievers may be used for muscle or nerve pain.
  • Fiber supplements may be recommended for constipation.
  • People with Parkinsons disease may develop difficulty in swallowing, with food and drink going down the wrong pipe and into the airway, rather than the stomach. Using thickeners for liquids can help prevent this problem.
  • Your doctor may recommend vitamin D or calcium supplements to help maintain your bone health, as people with Parkinsons disease are increasingly at risk from falls and fractures.

Be sure to discuss any OTC medications, supplements, or herbal products with your doctor. Some can interact with prescription medications.

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.

Lifestyle And Other Protective Factors

Levodopa (L

Cigarette smoking and caffeine consumption are the two most consistent protective factors associated with a reduced risk of PD. Other reported associations include higher serum urate, ibuprofen use and exercise, among others. The negative association between cigarette smoking and PD is most intriguing. This inverse relationship is not easily explained, but some have suggested that PD-related cautious personality predisposes some individuals to quitting neuroprotective smoking as the biological mechanism involved in PD. The other hypothesis links nicotine to dopaminergic neuronal protection since it has been shown to stimulate the release of dopamine in the striatum and preserve dopaminergic function in experimental models. It is also possible that there are other unidentified neuroprotective components in cigarette smoke.

The relative risk reduction of PD among caffeine drinkers is between 0.5 and 0.8 and, similar to smoking, a dose-dependent effect has been consistently demonstrated in most studies. Caffeine, an antagonist of adenosine A2a receptor, has been postulated to exert neuroprotective role by blocking this receptor. In addition to caffeine, it is possible that antioxidants present in some beverages may contribute to a protective effect among black tea drinkers, independent of caffeine.

Medications To Avoid Or To Use With Caution

It can be challenging to keep track of all your medications, especially if youre using medications for both motor and non-motor symptoms. However, keeping an accurate up-to-date list of your medications decreases the likelihood of an unwanted medication interaction. Studies have found that one in three people with Parkinsons have been prescribed contraindicated drugs while they were hospitalized, which highlights the importance of having an up-to-date list of medications available at all times. Learn about medications to avoid or use with caution here.

Stay Safe With Your Medicines

Read all labels carefully.

  • Tell all your health care providers about all the medicines and supplements you take.
  • Know all the medicines and foods youâre allergic to.
  • Review any side effects your medicines can cause. Most reactions will happen when you start taking something, but thatâs not always the case. Some reactions may be delayed or may happen when you add a drug to your treatment. Call your doctor right away about anything unusual.
  • Use one pharmacy if possible. Try to fill all your prescriptions at the same location, so the pharmacist can watch for drugs that might interact with each other.
  • You can use online tools to see if any of your medicines wonât work well together.

You have the right and responsibility to know what medications your doctor prescribes. The more you know about them and how they work, the easier it will be for you to control your symptoms. You and your doctor can work together to create and change a medication plan. Make sure that you understand and share the same treatment goals. Talk about what you should expect from medications so that you can know if your treatment plan is working.

Impulsive And Compulsive Behavior

Some people taking dopamine agonists may experience problems with impulsive or compulsive behaviours. For example an increased desire to gamble or engage in sexual activity. These behaviours often develop slowly so may not seem to be a problem immediately. It is important for both the person living with Parkinsons and their family to be aware of this side effect. If affected by this side effect, a reduction in dose or stopping the medication will stop the behaviour.

Other Types Of Parkinsonism

Like Parkinsons, MSA can cause stiffness and slowness of movement in the early stages. However, people with MSA can also develop symptoms that are unusual in early Parkinsons, such as unsteadiness, falls, bladder problems and dizziness.

PSP affects eye movement, balance, mobility, speech and swallowing. Its sometimes called Steele-Richardson-Olszewski syndrome.

Normal pressure hydrocephalus mainly affects the lower half of the body. The common symptoms are walking difficulties, urinary incontinence and memory problems. Removing some cerebrospinal fluid through a needle in the lower back can help with these symptoms in the short term. If there is improvement after this procedure, an operation to divert the spinal fluid permanently can help in the long term.

While these are not parkinsonian disorders, you may be diagnosed with one of these conditions if tremor is your only symptom.

There are several other, much rarer, possible causes of parkinsonism. These include rare conditions like Wilsons disease, an inherited disorder where theres too much copper in your bodys skin and muscles.

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.

Support For People Living With Parkinsons Disease

While the progression of Parkinsons is usually slow, eventually a persons daily routines may be affected. Activities such as working, taking care of a home, and participating in social activities with friends may become challenging. Experiencing these changes can be difficult, but support groups can help people cope. These groups can provide information, advice, and connections to resources for those living with Parkinsons disease, their families, and caregivers. The organizations listed below can help people find local support groups and other resources in their communities.

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 .
