Medical Definition of Droxidopa

1. A precursor of noradrenaline that is used in the treatment of parkinsonism. The racaemic form (dl-threo-3,4-dihydroxyphenylserine) has also been used, and has been investigated in the treatment of orthostatic hypotension. There is a deficit of noradrenaline as well as of dopamine in parkinson's disease and it has been proposed that this underlies the sudden transient freezing seen usually in advanced disease. Administration of dl-threo-3,4-dihydroxyphenylserine has been claimed to result in an improvement in this phenomenon but controlled studies have failed to demonstrate improvement.
