 | Chemical Properties | White Solid |  | Uses | A synthetic amino acid precursor of Norepinephrine. Antiparkinsonian. |  | Definition | ChEBI: Droxidopa is a serine derivative that is L-serine substituted at the beta-position by a 3,4-dihydroxyphenyl group. A prodrug for noradrenalone, it is used for treatment of neurogenic orthostatic hypotension It has a role as a prodrug, a vasoconstrictor agent and an antihypertensive agent. It is a L-tyrosine derivative and a member of catechols. |
