Chelsea Therapeutics Announces FDA Acceptance of NORTHERA(TM) (droxidopa) NDA

                      *PDUFA Date Set as January 3, 2014

CHARLOTTE, N.C., July 17, 2013 (GLOBE NEWSWIRE) -- Chelsea Therapeutics
International, Ltd. (Nasdaq:CHTP) today announced that the U.S. Food and Drug
Administration (FDA) has acknowledged receipt of the New Drug Application
(NDA) resubmission seeking approval to market NORTHERA™ (droxidopa), an orally
active synthetic precursor of norepinephrine, for the treatment of symptomatic
neurogenic orthostatic hypotension (NOH) in patients with primary autonomic
failure (Parkinson's disease, multiple system atrophy and pure autonomic
failure), dopamine beta hydroxylase deficiency and non-diabetic autonomic
neuropathy. The FDA has deemed the resubmission a complete response to its
March 28, 2012 Complete Response Letter and assigned a new Prescription Drug
User Fee Act (PDUFA) goal date of January 3, 2014.

"Northera holds the potential to serve as an important new therapeutic option
for patients living with the debilitating effects of NOH," said Joseph G.
Oliveto, Interim Chief Executive Officer of Chelsea. "FDA acknowledgement of
the completeness of our NDA resubmission is another key milestone in reaching
this goal. We will continue to work closely with the FDA toward an approval
decision for Northera by early next year, and advance our commercial strategy
in anticipation of a U.S. commercial launch soon after this."

Northera was previously granted Orphan Drug Designation and received Fast
Track designation from the FDA.Fast Track designation is designed to
facilitate the review of products that address serious or potentially
life-threatening conditions for which there is an unmet medical need.

About Symptomatic NOH

NOH is a chronic neurogenic disorder resulting from deficient release of
norepinephrine that predominantly affects patients with primary autonomic
failure, a group of diseases which includes Parkinson's disease (PD), multiple
system atrophy (MSA) and pure autonomic failure (PAF). Symptoms of NOH
include: dizziness, lightheadedness, blurred vision, fatigue, poor
concentration, and fainting episodes when a person assumes a standing
position, often severely limiting a person's ability to perform routine daily
activities that require standing or walking for both short and long periods of

About Northera

NORTHERA™ (droxidopa), the lead investigational agent in Chelsea Therapeutics'
pipeline, is currently in Phase III development for the treatment of
symptomatic neurogenic orthostatic hypotension (NOH) in patients with primary
autonomic failure — an indication that includes a significant number of
patients with Parkinson's disease, multiple system atrophy (MSA) and pure
autonomic failure (PAF). Droxidopa is a synthetic catecholamine that is
directly converted to norepinephrine (NE) via decarboxylation, resulting in
increased levels of NE in the nervous system, both centrally and peripherally.

Droxidopa, developed by and licensed from Dainippon Sumitomo Pharma Co., Ltd.
(DSP), initially received Japanese approval in 1989 for the treatment of
frozen gait and dizziness on standing associated with Parkinson's Disease and
for the treatment of orthostatic hypotension, syncope or dizziness on standing
associated with Shy-Drager syndrome and Familial Amyloidotic Polyneuropathy.
In 2000, Droxidopa received expanded marketing approval to include prevention
of vertigo, dizziness and weakness associated with orthostatic hypotension in
hemodialysis patients.
