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.
Medical Marijuana As A Treatment For Parkinsons Symptoms
Parkinsons disease is a disorder of the central nervous system that causes tremors, slow movement, stiffness, and loss of balance. Because marijuana directly affects the central and peripheral nervous systems, scientists have studied the effect of marijuana as a treatment for Parkinsons symptoms.
A 2020 review of 14 different studies acknowledged evidence that medical marijuana provides a reduction in anxiety, tremors, and involuntary or erratic movements. However, the researchers concluded that there is insufficient evidence to recommend medical marijuana use as part of Parkinson’s treatment.
A 2017 study with patients who used medical marijuana over three months to manage Parkinson’s symptoms found that the treatment improved their symptoms and did not cause major adverse effects.
Other research has shown that medical marijuana may be able to help with some Parkinsons disease symptoms, including:
- Smoking
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 , .

Rasagiline: A Treatment For Parkinson’s
22 November, 2019
Parkinsons disease is one of the most common neurodegenerative diseases. Rasagiline, also known under the brand name Azilect, is a highly effective pharmaceutical treatment for this condition. Its similar to selegiline, and has been proven to improve a patients motor function within one day after starting treatment.
According to its data sheet, this medication is good for treating Parkinsons disease either on its own or in conjunction with other medications such as levodopa. Its generally most effective on its own during the early stages of the disease. Once the disease has become more advanced, its better to combine it with other medications.
The first thing patients will notice is an improvement in motor function. With time, it can also help with the stiffness, bradykinesia, and shaking. Many studies have shown that rasagiline is an effective treatment for Parkinsons.
Like we mentioned above, this treatment is most commonly sold under the brand name Azilect. Its an oral medication that comes in 1-milligram doses once per day, whether theyre also using levodopa or not. Theres no need to adjust the doses, and patients can take it with or without food. They can also use it with other Parkinsons treatments.
Traditional Chinese Medicine And Acupuncture
Traditional Chinese Medicine views disease as caused by internal imbalances. It has historically been used to treat Parkinson disease with acupuncture and individually prepared herbal remedies. One study showed that acupuncture improved symptoms in a small group of people with Parkinson disease. People with Parkinson disease may also find that acupuncture helps them sleep better. If you consult a TCM practitioner, make sure your doctor is aware of any suggested treatment.

Surgery: Deep Brain Stimulation For Parkinsons Disease
Deep brain stimulation is a surgery used to control Parkinsons motor symptoms including tremor, slowness of movement and stiffness. DBS was FDA-approved for Parkinsons disease in 2002 and works by delivering electrical pulses to specific areas of your brain that control movement. These electrical pulses disrupt the abnormal nerve signaling happening in your brain . By interrupting the abnormal signals, DBS can improve your motor symptoms, reduce on/off fluctuations and reduce the severity of dyskinesia .16 Some new research suggests DBS used in people with early-onset Parkinsons may actually slow down the progression of tremors.14
If you undergo DBS, you will likely be awake for the first part of the surgery, although DBS can in some cases be performed under general anesthesia, while youre asleep.9 Talk to your doctor about which option makes the most sense for your body. Heres what you might expect if you and your doctor decide DBS is right for you.
The first step is placing a halo a metal ring screwed into your head that keeps your head from moving. Local anesthesia is provided so it is not painful. However, some surgeries are now frameless and dont require a halo. Then, youll receive a local anesthetic while a small hole is made in your skull, near your ear. Through this hole, a wire connected to an electrode is placed in one or both sides of your brain in the areas that control movement. The wire and electrode are very thin.8
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.

Medications For Parkinson’s Symptoms
Most Parkinson’s medications treat motor symptoms of the disease. These symptoms can include:
- Resting tremor
- Imbalance while standing or walking
- Gait freezing
- Bradykinesia
Treatment for these symptoms can include:
Carbidopa-levodopa: Levodopa is considered to be the “gold standard” for Parkinson’s treatment. It’s a natural chemical that passes into the brain, where it’s converted to dopamine. Levodopa is combined with carbidopa to prevent levodopa from converting into dopamine early, outside of the brain.
After some time taking dopamine treatments the amount of time varies from patient to patient it may begin to be less effective. This means you may experience what are called “off” times during which your treatment isn’t working optimally, but before it’s time for your next treatment.
Long-term use of levodopa can also cause dyskinesia, involuntary movements that are often mistaken for Parkinson’s symptoms themselves.
Duopa/Duodopa: A brand-name medication sometimes prescribed later in the Parkinson’s disease course, Duodopa is made up of carbidopa/levodopa and administered through a feeding tube. It can be an option for patients who still respond to levodopa, but experience a lot of “off” time. Duopa is continuously delivered, keeping blood levels of the two drugs constant.
Advanced And Future Treatments For Parkinsons
While theres no cure for Parkinsons disease, recent research has led to improved treatments.
Scientists and doctors are working together to find a treatment or prevention technique. Research is also seeking to understand who is more likely to develop the disease. In addition, scientists are studying the genetic and environmental factors that increase the chance of a diagnosis.
Here are the latest treatments for this progressive neurological disorder.
In 2002, the FDA approved deep brain stimulation as a treatment for Parkinsons disease. But advances in DBS were limited because only one company was approved to make the device used for the treatment.
In June 2015, the FDA approved the

Indulge Yourself In The Following Activities As A Part Of Parkinsons Disease Treatment
A Daily Walk
If you cannot afford for a workout, you can at least afford for a daily walk, anytime in a day. However, working out is not much recommended for patients undergoing Parkinsons disease treatment as the muscles and nerves should be treated carefully without any rigid movement.
You can have a stroll around your nearby park to relax and have the best time. A regular morning, as well as an evening walk, can show a tremendous effect on your physical movement. It helps in relieving you from the stiffness and brings more flexibility to your body.
Some Simple Stretches
Simple stretches are recommended for people undergoing Parkinsons disease treatment as this is going to bring flexibility in the body and improve your movement day after day. The stretches mentioned are very elementary and are very effective in the reducing the effects of Parkinsons disease.
Wall Stretch
You can practice this at any time in your home. Stay about 2 feet away from the wall. Place both hands on the wall and lean forward. Bend your knee forward and stay in the position for twenty seconds. Shift the leg and repeat the same.
Quad Stretch
Stand erect with both the hands placed on either side of your body. Lift one of your legs and try to grab the foot of your leg with the respective side of your hand. Hold for 30 seconds and remain in the position. Relax and repeat the same with another leg.
Leg Stretch
Practice the same with the alternate hand.

Medical Treatment Of Parkinsons Disease
Enormous progress has been made in the treatment of Parkinsons disease over the past half century, but levodopa remains the most potent drug for controlling PD symptoms . Prior to instituting medical therapy, a correct diagnosis of PD must be established and the level of impairment determined . Each patients therapy is to be individualized, and diverse drugs other than levodopa are presently available. Among these are the dopamine agonists , catechol-o-methyl-transferase inhibitors and nondopaminergic agents . Head-to-head comparisons of drugs within classes are rare, and the differences that have emerged are related to the effects on motor fluctuations, dyskinesias, on/off times and adverse effects of the specific agents within each class .

Parkinsons disease is the second-leading cause of dementia and is characterized by a progressive loss of dopaminergic neurons in the substantia nigra alongside the presence of intraneuronal -synuclein-positive inclusions. Therapies to date have been directed to the restoration of the dopaminergic system, and the prevention of dopaminergic neuronal cell death in the midbrain. This review discusses the physiological mechanisms involved in PD as well as new and prospective therapies for the disease. The current data suggest that prevention or early treatment of PD may be the most effective therapeutic strategy. New advances in the understanding of the underlying mechanisms of PD predict the development of more personalized and integral therapies in the years to come. Thus, the development of more reliable biomarkers at asymptomatic stages of the disease, and the use of genetic profiling of patients will surely permit a more effective treatment of PD.
What Is Parkinsons Disease
Parkinsons disease, PD a heavy and progressive disease of the central nervous system that affects the motor, and at later stages cognitive function. The disease acts on an area in the midbrain called the substantia nigra that controls movement, affecting neurons that produce a chemical messenger . Progression of the disease results in decreased levels of dopamine as these neurons are destroyed, resulting in abnormal brain activity predominantly uncontrolled movement. Scientists have not been able to ascertain the cause of Parkinsons disease, but have found a clear genetic link, as well as the pathogenic role of some neurotoxins, such as Lewy bodies. Symptoms resembling PD may occur with prolonged use of certain medications that block the action of dopamine. PD is less common in young adults it usually develops in people around the age of 60 and older, affecting more men than women. PD is a form of parkinsonism which is used to describe symptoms associated with PD but due to other causes, treatment may be of benefit to these such causes, and so its important to distinguish between the two disorders.

Other Therapies To Consider
Trained therapists across a number of disciplines can work with you to develop exercises and lifestyle strategies to improve specific challenges youre having as a result of Parkinsons disease. You dont have to wait until youre struggling to seek out a therapist its important to intervene early. These lifestyle changes will hopefully benefit you now and down the road.37
Physical Therapy
A physical therapist can help you do exercises to improve your balance, gait, coordination and dealing with symptoms like freezing. For example, a physical therapist can teach you to cope with freezing episodes by using a laser which projects a line on the ground, stepping over such lines on the ground to cue your brain to start moving again, and walking assisted by rhythmic musical cues.13
One specific type of physical therapy for Parkinsons is LSVT BIG, which utilizes overexaggerated movements to retrain your bodys smaller, slower movements caused by Parkinsons. For example, buttoning a button with more purposeful, forceful movements, like youre angry at the buttons, can help you button faster.22 Some research found LSVT BIG to be more effective at improving your movement abilities than general exercise.24
Occupational Therapy
Occupational therapists teach you how to do everyday activities that have become difficult for you. For example, how to do daily tasks when you have a tremor and how to keep track of when your food has gone bad after you lose your sense of smell.13
On And Off Periods With Parkinsons
As your Parkinsons progresses over the years, you will probably start to notice even though youre still taking your carbidopa-levodopa regularly, you experience periods where its working effectively and then periods where the medication seems to not be working . When youre on, you should feel like you can move more normally, with less tremor, stiffness and/or slowness. And then when youre off, all those stiff, rigid, slow movements and your tremor return, almost as if your medications have decided to stop working. Frustratingly, it can be hard to predict exactly how long your on and off periods will last.
Off periods are a result of the disease progressing and becoming harder to control through medication. When you first start medication, its common to go through a honeymoon period of several years, where its working well and you can hardly tell you have Parkinsons.23 Then, as the condition progresses, your body produces less dopamine, making you more dependent on your dopamine-replacement medication. Over time this leads to more and more instances where the medication is supposed to kick in, or supposed to last for several hours, but is less effective.31

Monoamine Oxidase B Inhibitors
Selegeline is an example of this class of drug. It selectively and irreversibly inhibits intracellular and extracellular monoamine oxidase B and therefore reduces or delays the breakdown of dopamine to dihydroxyphenylacetic acid and hydrogen peroxide. The latter has been implicated in oxidative damage in dopaminergic neurons in the substantia nigra. It also inhibits reuptake of dopamine from the synaptic cleft. Adding selegeline to L-dopa may allow a reduction of the L-dopa dose of 10%15%, occasionally up to 30%.Mild L-dopa response fluctuations can often be reduced by adding selegeline. Monotherapy in de novo patients delays the need for additional treatment by approximately a year.Possible neuroprotective effects will be discussed later . Side effects of L-dopa, including dyskinesias and psychiatric problems, are potentially enhanced by selegeline. Orthostatic hypotension may also occur.

Treatment Of Neurobehavioral Features
Treatment of cognitive deficits associated with PD is as challenging as the treatment of Alzheimers disease and other dementias. While the general assumption has been that cognitive deficits are a feature of late-stage PD, clinically inapparent cognitive changes on neuropsychiatric testing may be found . With the introduction of cholinesterase inhibitors such as donepezil , rivastigmine , and galantamine and the NDMA antagonist memantine , it is possible that cognition, orientation and language function will improve, and that such improvement will lead to a meaningful improvement in function. Both donepezil and rivastigmine improve cognition to the same effect, but donepezil is better tolerated . The largest and best-designed study of rivastigmine in dementia associated with PD involved 541 patients enrolled in a 24-week randomized, multicenter, double-blind clinical trial . The patients had a relatively mild dementia , with onset of dementia about 2 years after onset of PD symptoms. The mean ADAS-cog score, the primary efficacy variable, improved by 2.1 points in the rivastigmine group, compared to 0.7 in the placebo group , and the MMSE improved by 0.8 in the rivastigmine group and worsened by 0.2 in the placebo group . At the end of the study, 55.5% were receiving 9 to 12 mg. The adverse effects that were significantly more frequent in the rivastigmine group were nausea, vomiting, dizziness, and tremor.
