The treatment of orthostatic hypotension with dihydroxyphenylserine.
Neurogenic orthostatic hypotension is an incapacitating symptom of central and peripheral autonomic nervous system degeneration. It occurs in such clinical conditions as multiple system atrophy, pure autonomic failure, and small-fiber peripheral neuropathies. Although many treatments are available, their effects are inconsistent, unsustained, and complicated by side effects. 3,4-Dihydroxyphenylserine is a synthetic, unnatural amino acid that is an immediate norepinephrine precursor. There is theoretical and clinical evidence supporting the use of this agent in the treatment of neurogenic orthostatic hypotension in patients with peripheral and central autonomic nervous system dysfunction. We review the biochemistry, pharmacokinetics, and possible mechanisms of action and clinical utility of this agent in the treatment of neurogenic orthostatic hypotension.
