Cardiovascular Safety Considerations in the Treatment of Neurogenic Orthostatic Hypotension

The American Journal of Cardiology, 2020
Neurogenic orthostatic hypotension (nOH), a drop in blood pressure upon standing resulting from autonomic malfunction, may cause debilitating symptoms that can affect independence in daily activities and quality-of-life. nOH may also be associated with cardiovascular comorbidities (e.g., supine hypertension, heart failure, diabetes, and arrhythmias ...

Early postural blood pressure response and cause-specific mortality among middle-aged adults [PDF]

, 2011
Orthostatic hypotension (OH) is associated with increased total mortality but contribution of specific death causes has not been thoroughly explored. In this prospective study, authors followed up 32,068 individuals without baseline history of cancer or ...

L-Dops and the Treatment of Neurogenic Orthostatic Hypotension

Future Neurology, 2013
L-threo-dihydroxyphenylserine (L-DOPS) is an oral prodrug that is converted to the sympathetic neurotransmitter noradrenaline through a single-step decarboxylation by the endogenous enzyme 3,4-dihydrophenylalanine decarboxylase. DOPS can provide an exogenous source of noradrenaline to adrenergic neurons that are involved in the maintenance of blood ...
