13. What is levodopa?
The main therapy for Parkinson's disease is the drug levodopa, also called L-dopa. It is a simple chemical found naturally in plants and animals. Nerve cells use levodopa to make dopamine to replenish the brain's supply. Levodopa helps to reduce tremors and other symptoms of Parkinson's disease during the early stages of the disease. It allows most people with Parkinson's to extend the period of time in which they can lead relatively normal, productive lives.
