| DROXIDOPA Usage And Synthesis |
| 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. | | Description | Droxidopa (L-DOPS) is a synthetic precursor and prodrug of the neurotransmitter norepinephrine. It is transformed into norepinephrine through the action of DOPA decarboxylase. L-DOPS increases norepinephrine levels in the rat heart following intraperitoneal administration and in the brain following intracerebroventricular administration at doses of 125 and 100 μg/animal, respectively. It increases arterial pressure and mesenteric arterial resistance in rats with ligated portal vein or biliary ducts when used at doses of 25-50 mg/kg. L-DOPS crosses the blood brain barrier, however, its effects can be blocked by the peripherally-restricted DOPA decarboxylase inhibitor carbidopa , indicating that the mechanism is peripheral. Formulations containing droxidopa are used in the treatment of neurogenic orthostatic hypotension. | | Chemical Properties | Off-White Solid | | Originator | Sumitomo (Japan) | | Uses | The L-threo-form Droxidopa. A synthetic amino acid precursor of Norepinephrine (N674500). Antiparkinsonian. | | Uses | Droxidopa is a psychoactive drug and acts as a prodrug to the neurotransmitters norepinephrine (noradrenaline) and epinephrine (adrenaline). | | Uses | L-DOPS has been administered for clinical trial studies in mice with amyloid pathology. | | Definition | ChEBI: 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 | | Brand name | DOPS | | General Description | L-DOPS, also called L-threo 3,4-Dihydroxyphenylserine or droxidopa is a catecholamine. L-DOPS has many clinical advantages and may be useful for treating norepinephrine deficiency. It is used for treating neurogenic orthostatic hypotension and improves norepinephrine levels. L-DOPS mediates reduction of amyloid plaques and could have a therapeutic potential for treating amyloid pathology. | | Biochem/physiol Actions | L-DOPS is a norepinephrine precursor in vivo. |
