Description

Droxidopa is a synthetic amino acid precursor of (-)-norepinephrine which is absorbed from the gut and metabolized to norepinephrine. In Parkinsonian patients, droxidopa added to existing levodopa/decarboxylase inhibitor therapy produces significant improvements in retropulsion, dysarthria and muscular rigidity refractory to other treatments; however, tremor was unaffected.
