BACKGROUND L-threo-3,4-dihydroxyphenylserine (L-DOPS), a norepinephrine (NE) prodrug, is investigational for orthostatic hypotension, which occurs commonly in Parkinsons disease. Adjunctive anti-parkinsonian drugs might interact with L-DOPS. We tested whether L-aromatic amino-acid decarboxylase inhibition by carbidopa (CAR) attenuates L-DOPS conversion to NE and blocks the pressor effect of L-DOPS, whereas catechol-O-methyltransferase inhibition by entacapone (ENT) interferes with L-DOPS metabolism and augments the pressor effect. METHODS Twelve patients with autonomic failure took 400 mg of L-DOPS with 200 mg of placebo (PLA), CAR, or ENT on different days. Plasma L-DOPS, NE, and deaminated NE metabolites (dihydroxyphenylglycol [DHPG], dihydroxymandelic acid [DHMA]) were measured. RESULTS L-DOPS+PLA and L-DOPS+ENT increased systolic pressure similarly (by 27 ± 8 and 24 ± 9 mm Hg at 3 hours). L-DOPS+CAR did not increase pressure. The peak increase in plasma NE (0.57 ± 0.11 nmol/L) averaged less

Droxidopa (INN; trade name Northera; also known as L-DOPS, L-threo-dihydroxyphenylserine, L-threo-DOPS and SM-5688) is a synthetic amino acid precursor which acts as a prodrug to the neurotransmitter norepinephrine (noradrenaline). Unlike norepinephrine, droxidopa is capable of crossing the protective blood-brain barrier (BBB). Neurogenic orthostatic hypotension (NOH) dopamine beta hydrolase deficiency, as well as NOH associated with multiple system atrophy (MSA), familial amyloid polyneuropathy (FAP), pure autonomic failure (PAF). Intradialytic hypotension (IDH) or hemodialysis-induced hypotension. Freezing of gait in Parkinsons disease (off-label) Droxidopa was developed by Sumitomo Pharmaceuticals for the treatment of hypotension, including NOH, and NOH associated with various disorders such as MSA, FAP, and PD, as well as IDH. The drug has been used in Japan and some surrounding Asian areas for these indications since 1989. Following a merger with Dainippon Pharmaceuticals in 2006, ...

Treatment of rats with noradrenaline stimulated $H_20_2$ generation in liver mitochondria using succinate, choline or glycerol 1-phosphate as substrate. The dehydrogenase activity with either succinate or choline as substrate showed no change, whereas that with glycerol 1-phosphate increased. 2. The effect was obtained with noradrenaline, but not with dihydroxyphenylserine. 3. Phenoxybenzamine and yohimbine, but not propranolol, prevented the response to noradrenaline treatment. 4. Phenylephrine could stimulate $H_20_2$ generation, whereas isoprenaline had only a marginal effect. 5. Theophylline treatment slightly decreased the generation of $H_20_2$ in liver mitochondria, but treatment with pargyline, Ro4-1284 and dibutyryl cyclic AMP had little effect. 6. These studies showed that noradrenaline might possibly be acting through the $\alpha_2$-adrenergic system.. ...

Noradrenaline (NA) is a neurotransmitter produced in the central nervous system by neurons localized essentially in the brainstem, particularly in the locus ceruleus (LC) (Foote et al., 1983). Through the activation of adrenoceptors and corresponding second messenger systems (Molinoff, 1984), NA participates in a variety of motor and mental functions, such as locomotor control, cognition, motivation, and attention (Foote et al., 1983). In addition to these classic transmitter signaling functions, NA is thought to play a key role in neuronal survival, differentiation and plasticity, and to participate in brain repair mechanisms. For instance, compounds that mimic or increase LC output, including NA itself, its precursorl-threo-3,4-dihydroxyphenylserine, and amphetamine, improve behavioral recovery (Feeney, 1998), stimulate neural sprouting and synaptogenesis (Lee et al., 1994; Stroemer et al., 1998) and limit neuronal death in experimental models of cerebral ischemia (Lee et al., 1994). Another ...

Fibromyalgia syndrome (FMS) and Chronic widespread pain (CWP) are two syndromes within a broader class known as functional somatic syndromes. Chronic widespread pain (CWP) is defined according to the American College of Rheumatology (ACR), as pain both above and below the waist involving both sides of the body and lasting for at least 3 months. Fibromyalgia syndrome (FMS), a subset of CWP, is a multisystem disease characterized by sleep disturbance, fatigue, headache, morning stiffness, paresthesias, and anxiety.. While there is debate as to specific etiology and pathogenesis, fibromyalgia is generally believed to be the result of a perturbation of central pain processing, specifically the neuroendocrine system. Fibromyalgia patients have been shown to have lower levels of metabolites from three neurotransmitters (serotonin, norepinephrine, and dopamine) in their cerebrospinal fluid (CSF) compared to healthy controls. The low rate of turnover of these neurotransmitters supports the hypothesis of ...

Dopamine β-hydroxylase (DBH) converts dopamine (DA) to norepinephrine (NE) in noradrenergic/adrenergic cells. DBH deficiency prevents NE production and causes sympathetic failure, hypotension and ptosis in humans and mice; DBH knockout (Dbh -/-) mice reveal other NE deficiency phenotypes including embryonic lethality, delayed growth, and behavioral defects. Furthermore, a single nucleotide polymorphism (SNP) in the human DBH gene promoter (-970C,T; rs1611115) is associated with variation in serum DBH activity and with several neurological- and neuropsychiatric-related disorders, although its impact on DBH expression is controversial. Phenotypes associated with DBH deficiency are typically treated with L-3,4-dihydroxyphenylserine (DOPS), which can be converted to NE by aromatic acid decarboxylase (AADC) in the absence of DBH. In this study, we generated transgenic mice carrying a human bacterial artificial chromosome (BAC) encompassing the DBH coding locus as well as ~45 kb of upstream and ~107 ...

The increases in MAP and HR recorded via telemetry during the first week after CBU are very similar to results published previously based on daily recordings with the dog resting quietly in a sling under laboratory conditions (28). The effects of CBU on PRA were also replicated; PRA was elevated on some days during the week following CBU but never suppressed below control levels. Furthermore, we also observed a significant increase in plasma NE in response to CBU. All of these responses are compatible with the hypothesis that CBU caused an increase in sympathetic outflow. However, contrary to our expectations, the initial increases in MAP, HR, and plasma NE were not sustained. Plasma NE and HR declined to control levels by the third week after CBU (Figs. 4 and 7). There was also a decline in MAP over the same time period, but MAP stabilized at a level that averaged 10 ± 3 mmHg above control during the third to fifth weeks after CBU (Fig. 2). There are a number of possibilities that could ...
