While there is currently no cure for Parkinson’s, there are a range of drugs that can be used to manage the symptoms of the condition.
These are the main types of drugs used to treat Parkinson’s: Levodopa, Dopamine agonists, MAO-B inhibitors, COMT inhibitors, Glutamate antagonist and Anticholinergics.
The symptoms of Parkinson’s happen when the level of dopamine, a chemical messenger in your brain, becomes too low. This is because many of the brain cells that produce dopamine have died or are dying.
Without enough dopamine, your movement slows down and it may take longer to do things. You may also lack co-ordination or your hands or other body parts may shake. Each type of drug works in a different way to alleviate this problem.
Most of the drugs work to help the movement symptoms of Parkinson’s either by: increasing the amount of Dopamine in the brain or stimulating the parts of the sense brain where Dopamine works, or blocking the action of other factors (enzymes) that break the down Dopamine.
