Description
Sources: https://www.ncbi.nlm.nih.gov/pubmed/21080185
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/23948989 http://www.accessdata.fda.gov/drugsatfda_docs/label/2010/021485s20lbl.pdf

Levodopa (L-DOPA) was first isolated from seedlings of Vicia faba by Marcus Guggenheim in 1913. Levodopa, a dopamine precursor, is an effective and well-tolerated dopamine replacement agent used to treat Parkinson's disease. Oral levodopa has been widely used for over 40 years, often in combination with a dopa-decarboxylase inhibitor carbidopa, which reduces many treatment complications, extending its half-life and increasing levodopa availability to the brain. Entacapone, a catechol-O-methyltransferase inhibitor, can also be used to improve the bioavailability of levodopa, especially when used in conjunction with a carbidopa.
