What drugs are used to treat Parkinson's disease?
COMT inhibitors (entacapone, tolcapone): These drugs decrease “wearing off” in advanced disease. They may make the side effects of carbidopa-levadopa worse. Amantadine: This may have a modest effect on motor symptoms in early Parkinson’s, but it is particularly helpful with treating dyskinesia.

Can Parkinson's disease be reversed?
If you have Parkinson’s disease, there aren’t any treatments that can slow, reverse or stop the condition’s progression. But although there is no cure, more than a dozen medications can help patients manage symptoms.
What is MAO B inhibitor?
MAO-B inhibitors (selegiline, rasagiline): These may have a mild symptomatic benefit early in the course of Parkinson’s disease. Similar to dopamine agonists, this medication may help to smooth the motor fluctuations in advanced disease. They may also be used with Sinemet to prolong the action of the Sinemet.
Why is speech therapy important?
Speech therapy is also beneficial because patients often develop a soft voice, and they can learn how to project their voice. Such therapy may also help if they develop swallowing problems. YouTube. For more information, watch Dr. Wyant’s talk from the University of Michigan’s 2016 Parkinson’s & You Symposium.
Can you take Sinemet at night?
If you miss a dose, your symptoms may return. Sinemet controlled-release tab: This drug can be given at night to help with early morning symptoms, or it may be used instead of the immediate-release version to decrease nausea.
What is the cause of Parkinson's disease?
The motor symptoms of Parkinson’s are caused by a lack of the neurotransmitter dopamine in the brain. This causes symptoms like: 1,2. Dopamine is the chemical messenger that is responsible for smooth, purposeful movement. The main drug treatments used for PD help increase dopamine levels in the brain.
What is the best medication for PD?
Amantadine, a mild NMDA receptor antagonist. It is important for people with PD to see a movement disorders specialist who is trained in the use of these drugs for PD. They understand the interactions of these drugs and how some drugs may make symptoms worse.
What are the symptoms of PD?

Is L-DOPA good for Parkinson's?
Levodopa, also known as L-DOPA, has long been, and continues to be, the most effective drug in treating Parkinson’s disease symptoms . Most people with Parkinson’s 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.
What are the side effects of L-DOPA?
There are side effects that can occur with Levodopa including nausea, fatigue and orthostatic hypotension.

Is there a cure for Parkinson's disease?
Parkinson’s disease (PD) is one of the common chronic degenerative conditions of the nervous system. There is currently no cure for PD, but a number of drugs offer benefits in terms of controlling the motor symptoms.
Is there a drug for PD?
There are currently no disease-modifying drugs for PD, but the treatments that are used can offer significant symptomatic relief of the motor symptoms. They offer little clinical benefit in terms of the non-motor manifestations of PD.
What is the precursor of dopamine?
In the classical biosynthetic pathway of dopamine, the direct metabolic precursor is L-dihydroxyphenylalanine (levodopa or L-DOPA) which is synthesized either directly from tyrosine (a non-essential amino acid) or indirectly from phenylalanine (an essential amino acid) (8).
Is there a treatment for PD?
CURRENT TREATMENTS. There are currently no disease-modifying drugs for PD, but the treatments that are used can offer significant symptomatic relief of the motor symptoms. They offer little clinical benefit in terms of the non-motor manifestations of PD.
How long does levodopa last?
Generally, the clinical effect of levodopa is noticed quickly, and may last for several hours, particularly in the early stages of disease (15). However, as disease becomes more advanced, the effect of the drug usually wears off after shorter durations, and an increased frequency of dosing is often required.
What is rotigotine patch?
Rotigotine patches, for example, are useful in patients that are unable to take oral medications, for example, when they are kept nil-by-mouth in preparation for surgery.
What happens when dopaminergic neurons are lost?
Loss of dopaminergic neurons results in disturbance of the normal balance between dopamine and acetylcholine in the brain, and anticholinergic drugs may lead to restoration and maintenance of the normal balance between these two neurotransmitters (33).

Medications For Parkinson’s Disease
- There are several different classes of drugs used to treat the symptoms of PD, including: 1. Dopamine therapy, notably carbidopa-levodopa therapy 2. Dopamine receptor agonists 3. Anticholinergics 4. MAO-B (monoamine oxidase-B) inhibitors 5. COMT (catechol-O-methyltransferase) inhibitors 6. Amantadine – a mild NMDA receptor antagonist 7. And other m...
Carbidopa-Levodopa Therapy
- The motor symptoms of Parkinson’s—resting tremor, bradykinesia (gradual loss and slowing down of spontaneous movement), rigidity, and postural instability (impaired balance)—are caused by a lack of the neurotransmitter dopamine in the brain. Dopamine is the chemical messenger that is responsible for smooth, purposeful movement. The main drug treatments used for PD hel…
Dopamine Receptor Agonists
- Dopamine receptor agonists are not as effective on the motor symptoms of PD as carbidopa-levodopa therapy, but they may have fewer side effects. Dopamine receptor agonists mimic dopamine in the brain, and neurons in the brain use the dopamine agonists instead of dopamine. This can provide relief from symptoms of PD, particularly the motor symptoms such as tremor, r…
Anticholinergics
- Anticholinergics block the action of acetylcholine, another neurotransmitter involved in messages from the brain to the muscles. Anticholinergics are frequently used in combination with other treatments for PD.4,5
MAO-B Inhibitors
- MAO is an enzyme found throughout the cells in the body. In the brain, MAO-B plays an important role in the breakdown of neurotransmitters (chemical messengers) like dopamine. MAO inhibitors block the action of the enzyme. Adding an MAO-B inhibitor to levodopa therapy slows the breakdown of levodopa and dopamine in the brain, and may boost the effect of levodopa.3,6
COMT Inhibitors
- COMT (catechol-O-methyltransferase) is an enzyme that metabolizes or degrades neurotransmitters such as dopamine. COMT inhibitors block the action of the COMT enzyme. Adding a COMT inhibitor to levodopa therapy slows the breakdown of levodopa and dopamine, and may boost the effect of levodopa by making more of it available in the brain.7,8
Amantadine, A Mild NMDA Receptor Antagonist
- Amantadine is a weak, uncompetitive antagonist of the N-methyl-D-aspartate (NMDA) receptor. While the exact way Amantadine works isn’t fully understood, scientists believe that the drug may increase dopamine release and block dopamine reuptake in the brain. Amantatine may provide relief from symptoms of PD, particularly dyskinesias and tremors.9,10
Other Medications
- Other medications that may be used in the treatment of PD include medications which treat specific symptoms, including dementia, hallucinations, delusions, depression, tremor, or orthostatic hypotension (a falling of blood pressure that occurs upon changing positions or standing).3Not all antipsychotic medications are considered safe for people with PD but there ar…
