Monoamine oxidase inhibitors (MAOIs)
prolong the effects of
dopamine in the brain by preventing its breakdown.
They also may prevent the removal of dopamine between nerve endings and enhance
release of dopamine from nerve cells. Rasagiline and selegiline are selective
monoamine oxidase (MAO-B) inhibitors.
MAO-B inhibitors may be used in the
early stages of
Parkinson's disease to treat very mild symptoms (such
as resting tremor) and delay the need for levodopa.
In people with advanced Parkinson's disease who are
taking levodopa, rasagiline or selegiline may be added to levodopa treatment to
motor fluctuations, increase the time of effect of the levodopa, and decrease
the amount of levodopa needed to control symptoms.
In the early stages of Parkinson's
disease MAO-B inhibitors may improve symptoms and can delay the need for
levodopa. But the benefits are considered modest.1
MAO-B inhibitors are helpful to many
people who have Parkinson's disease. Treatment with rasagiline or selegiline
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
