Etilevodopa (L-Dopa ethyl ester), an ethyl-ester prodrug of Levodopa, is rapidly hydrolyzed to Levodopa and ethanol by nonspecific esterases in the gastrointestinal tract. Etilevodopa is used for the treatment of Parkinson disease (PD). Levodopa is the direct precursor of dopamine and is a suitable prodrug as it facilitates CNS penetration and delivers dopamine.

How to use

In Vitro:

Etilevodopa (L-Dopa ethyl ester) passes unchanged through the stomach to the duodenum, where it is rapidly hydrolyzed by local esterases to Levodopa and ethanol, and is subsequently absorbed into the blood stream as Levodopa. Compared with standard Levodopa, Etilevodopa has greater solubility in the stomach, faster passage to the small intestine, and a shortened time to maximum Levodopa concentration.
