L-DOPS (L-threo-dihydroxyphenylserine; Droxidopa; SM-5688) is a psychoactive drug and synthetic amino acid precursor which acts as a prodrug to the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline).[1] Unlike norepinephrine and epinephrine themselves, L-DOPS is capable of crossing the protective blood–brain barrier (BBB).[1]

Neurogenic orthostatic hypotension (NOH),[2] as well as NOH associated with multiple system atrophy (MSA), familial amyloid polyneuropathy (FAP), pure autonomic failure (PAF), and Parkinson’s disease (PD).
Intradialytic hypotension (IDH) or hemodialysis-induced hypotension.
Hypotension associated with fibromyalgia syndrome (FMS) and chronic fatigue syndrome (CFS).[3]
History

L-DOPS was developed by Sumitomo Pharmaceuticals under the trade name Droxidopa for the treatment of hypotension, including NOH,[2] and NOH associated with various disorders such as MSA, FAP, and PD, as well as IDH. The drug has been used in Japan and some surrounding Asian areas for these indications since 1989. Following a merge with Dainippon Pharmaceuticals in 2006, Dainippon Sumitomo Pharma licensed L-DOPS to Chelsea Therapeutics to develop and market it worldwide except in Japan, Korea, China, and Taiwan.

Clinical trials
Though L-DOPS has been used in Japan and Southeast Asia already for some time, it is also currently in clinical trials at the phase III point in the United States (U.S.), Canada, Australia, and throughout Europe. Provided L-DOPS successfully completes clinical trials, it could be approved for the treatment of NOH as early as 2011.[4] Additionally, phase II clinical trials for IDH are also underway. Chelsea Therapeutics obtained orphan drug status (ODS) for L-DOPS in the U.S. for NOH, and that of which associated with PD, PAF, and MSA, and is the pharmaceutical company developing it in that country.
