This study is designed to supply L-DOPS (droxidopa) on a long term basis to patients with a genetic form of profound orthostatic hypotension, most commonly DBH deficiency. It also allows us to collect medical history information on this small population of patients that would allow us to determine if there are any complications from this type of treatment.

Drug: droxidopa

Study Type: Interventional

Arms Assigned Interventions
L-DOPS (droxidopa)
Supply L-DOPS (droxidopa) on a long term basis to patients with a genetic form of profound orthostatic hypotension, most commonly DBH deficiency.
Drug: droxidopa
Droxidopa (L-DOPS) comes in capsule form, 100 mg or 200 mg strength and is usually administered 2 - 3 times per day. It would be taken indefinitely to improve symptoms of orthostatic hypotension
Other Names:
  • L-DOPS
  • DOPS


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 18 years old or older with orthostatic hypotension
  • established diagnosis of DBH deficiency and fractionated plasma catecholamine levels that show high dopamine levels and very low norepinephrine and epinephrine levels. Blood pressure increase in response to oral treatment with L-DOPS during previous studies.

Exclusion Criteria:

  • subjects with orthostatic hypotension that do not have a genetic form of the disorder and catecholamine pattern is not consistent with that above.
